Why You Should Keep Reading

If you’re serious about growing your eyewear business with TR90 frames, this guide will give you a clear roadmap—whether you’re just starting or looking to switch suppliers for better results.

Part 1: What Are TR90 Eyeglass Frames?

TR90 eyeglass frames are made from a type of thermoplastic material developed using Swiss technology. This material, known as TR90, is widely used in the eyewear industry due to its exceptional flexibility, lightness, and resistance to damage. In simple terms, TR90 frames are built to be comfortable, durable, and unbreakable under normal use—making them ideal for daily wear, sports, and even children’s eyewear.

What Makes TR90 Material Unique?

TR90 is a memory plastic, meaning it can bend and return to its original shape without warping. It’s also heat-resistant, chemical-resistant, and non-toxic, which makes it safe for users with sensitive skin. Many eyewear brands prefer TR90 for its ability to combine practical performance with stylish frame design.

Whether you’re selling to athletes, students, professionals, or fashion-conscious consumers, TR90 optical frames can meet a wide variety of needs.

Key Advantages of TR90 Eyewear Frames

1. Ultra-Lightweight
   TR90 frames are significantly lighter than acetate or metal, making them more comfortable for long hours of wear.
2. Highly Flexible and Durable
   They can twist or bend without breaking. Perfect for daily wear, rough handling, or customers with active lifestyles.
3. Impact Resistant
   Ideal for kids’ frames and sports sunglasses. They’re tough enough to handle accidental drops or pressure.
4. Hypoallergenic
   TR90 is non-irritating and suitable for sensitive skin, unlike some low-grade plastics or metal alloys.
5. Heat and Chemical Resistant
   TR90 maintains its shape and color even in high-temperature or high-humidity environments.
6. Customizable for Branding
   The surface of TR90 is suitable for logo printing, laser marking, and various coating finishes—making it an excellent option for private label eyewear brands.

TR90 vs. Other Frame Materials

Feature / Material	TR90	Acetate	Metal (e.g. Stainless Steel)	Injection Plastic
Weight	★★★★★ Ultra-light	★★★ Medium	★★★★ Light	★★★ Light
Flexibility	★★★★★ Excellent	★★ Low	★★★ Medium	★ Low
Durability	★★★★ Durable	★★★ Medium	★★★★ High	★★ Low
Comfort for Long Wear	★★★★★ Excellent	★★★ Good	★★★ Good	★★ Poor
Skin Safety	Hypoallergenic	Usually safe	Usually safe	May contain irritants
Cost	Affordable	Mid to high	Higher	Low

 Conclusion: TR90 eyeglass frames offer the best combination of weight, comfort, and toughness—especially for customers who value comfort without sacrificing design.

Who Uses TR90 Frames?

• Optical shops looking for lightweight prescription frames
• Sports eyewear brands needing flexibility and durability
• Children’s eyewear suppliers focusing on safety
• Fashion brands needing customizable frame colors and styles
• Online retailers looking for bulk-ready or fast-selling stock styles

Whether you’re wholesaling ready stock or planning to launch your own eyewear line, TR90 frames are one of the most profitable and low-risk categories in the market today.

Part 2: Types of TR90 Eyeglass Frames

TR90 is not just one style or category—it’s a versatile frame material that can be molded into a wide range of designs, colors, and functions. Depending on your brand positioning and customer needs, different types of TR90 eyeglass frames serve different markets—from functional sport eyewear to fashionable optical frames.

Below are the most common and profitable types of TR90 frames to consider when sourcing from China:

1. Full TR90 Frames

These are frames made entirely from TR90 material—including the front frame and temples.
They are:

• Extremely lightweight
• Flexible and unbreakable
• Perfect for daily optical use

 Ideal for: Optical shops, everyday users, budget-friendly collections

2. TR90 with Metal Temples

This type combines the comfort of TR90 on the front with the structure of metal temples. It adds a more premium or fashionable feel to the frame while still maintaining flexibility.

• Stylish, structured look
• Better weight balance
• Often used in business or unisex styles

 Ideal for: Office wear, adult optical frames, modern fashion collections

3. TR90 Sport Frames

Designed specifically for active lifestyles, TR90 sport frames are:

• Impact-resistant
• Designed with rubberized or non-slip finishes
• Often wrap-around or larger in shape

These frames are used not only in sports sunglasses but also in optical frames for athletes or outdoor professionals.

 Ideal for: Sports brands, cycling/running shops, safety eyewear distributors

4. TR90 Kids’ Frames

TR90’s unbreakable and skin-safe qualities make it perfect for children. These frames are often colorful, soft-edged, and designed to handle rough use.

Features include:

• No metal parts – Safe and soft for children
• Bright colors and fun shapes
• Often come with strap holders or bendable temples

 Ideal for: Pediatric eyewear suppliers, school frame programs, children’s brands

5. TR90 Sunglasses

TR90 is widely used in fashion sunglasses due to its shape memory, lightweight feel, and compatibility with various lens types like polarized, gradient, or mirrored lenses.

Key selling points:

• Won’t slide or cause discomfort during hot weather
• Easy to mold into oversized, retro, or cat-eye shapes
• Durable enough for beach, driving, or travel use

 Ideal for: Fast fashion sunglasses, travel brands, optical retailers expanding into sunwear

6. TR90 Hybrid Frames (Combo)

These are customized TR90 frames mixed with other materials like:

• Acetate temples
• Metal bridges
• Silicone nose pads

Such designs are often used by independent brands who want something unique and eye-catching while still benefiting from TR90’s durability and comfort.

 Ideal for: Private label brands, niche designers, boutique collections

Why Understanding TR90 Frame Types Matters

When working with Chinese suppliers, clearly identifying the type of TR90 frame you need helps avoid misunderstanding and ensures faster quoting and sampling. Some manufacturers—like Eyewearglobo—have experience across all types, and can recommend styles based on your:

• Target market
• Price point
• Design style
• MOQ and lead time

If you’re not sure which type fits your business best, start with ready-stock full TR90 frames, and then expand into custom or hybrid designs as your brand grows.

Part 3: How to Wholesale TR90 Eyeglass Frames from China?

Step 1: Find the Best Places to Look for Eyewear Manufacturers

The first and most important step to successfully wholesale TR90 eyeglass frames from China is finding the right supplier. A good supplier will not only deliver the right products, but also ensure smooth communication, timely delivery, and long-term partnership potential.

Here are three proven ways to find reliable TR90 eyewear manufacturers in China:

1.1 Use Google – The Smart Way

Many experienced eyewear wholesalers start their sourcing journey on Google—and for good reason. A well-optimized supplier website often signals serious investment in international business and a stable production setup.

To begin, try searching with specific keywords such as:

• “TR90 eyeglass frame manufacturer in China”
• “custom TR90 eyewear supplier”
• “wholesale TR90 optical frames factory”
• “TR90 sunglasses OEM China”

From the search results, focus on suppliers with:

• A professional website (look for .com domains, clear contact info, product categories)
• Certifications mentioned (CE, FDA, ISO)
• Real factory photos or videos
• Downloadable catalogs or product listings

 Example: Eyewearglobo is a trusted Chinese eyewear manufacturer specializing in TR90 frames for global B2B buyers. With 5 production lines and support for custom and ready-stock orders, they are a strong choice for importers looking for a balance of price and quality.

1.2 Use Alibaba – For Pricing Comparison & Factory Vetting

Alibaba.com remains one of the most popular platforms for sourcing eyewear from China. It allows you to compare multiple TR90 frame suppliers quickly and request quotations based on your target specs.

When using Alibaba:

• Filter by Gold Supplier, Verified, and Trade Assurance
• Check MOQs, response rates, and certifications
• Look at customer reviews and factory videos
• Don’t choose purely by the lowest price—quality and communication matter more

 Tip: Message 3–5 suppliers with the same RFQ (Request for Quote), and compare how detailed and professional their responses are. This often shows how they will treat you as a long-term partner.

1.3 Attend Eyewear & Optical Exhibitions

If you’re serious about building long-term relationships or want to inspect products in person, consider attending trade fairs and expos related to eyewear.

Popular trade shows for eyewear sourcing:

• Canton Fair (Guangzhou, China) – Large-scale sourcing fair with dedicated eyewear sections
• SILMO (Paris) – International eyewear show featuring both brands and OEM/ODM factories
• Hong Kong Optical Fair – Highly focused on eyewear and accessories, many Chinese TR90 frame factories exhibit here

Meeting suppliers face-to-face helps you:

• Verify their professionalism
• Check the real quality of TR90 frames
• Negotiate better pricing or custom deals

 Even if you can’t attend in person, many Chinese suppliers offer virtual exhibitions or video factory tours—just ask.

Step 2: Communicate with Manufacturers

Once you’ve shortlisted a few promising TR90 eyeglass frame suppliers, the next step is communication—and it’s more important than many people realize.

Clear, professional, and efficient communication not only saves time but also reduces the risk of misunderstandings, wrong samples, or delays in production.

2.1 Start with a Clear Introduction

When reaching out to suppliers (whether via email, Alibaba, or WhatsApp), avoid generic one-liners like:

“Hi, I want to buy TR90 glasses. Please send price.”

Instead, give them a brief and structured message that shows you’re serious. For example:

Subject: TR90 Eyeglass Frame OEM Inquiry

Hello,

My name is [Your Name], and I’m the purchasing manager at [Your Company Name], an eyewear distributor based in [Country]. We are looking for a reliable supplier for TR90 optical frames and sunglasses.

Could you please send me:

• Product catalog (TR90 models)
• MOQ for custom branding
• Lead time
• CE/FDA certifications

Looking forward to your reply.

Best regards,
[Your Name]

2.2 What to Ask Suppliers Upfront

Here’s a checklist of essential questions when sourcing TR90 frames from China:

•  What is the MOQ (Minimum Order Quantity) for TR90 frames?
•  Do you support custom logo printing or private labeling?
•  What’s the lead time for ready stock vs custom models?
•  Are your frames made with 100% TR90 material?
•  Do you have CE or FDA certifications for export?
•  Can you provide samples, and what’s the sample policy?
•  What is your warranty or after-sales policy?

Asking these early helps filter out the suppliers who are not experienced, certified, or responsive enough for long-term cooperation.

2.3 What to Avoid During Communication

To protect your business from costly mistakes, avoid these common communication errors:

Mistake	Why It’s a Problem
Being vague (“I want good quality TR90”)	“Good quality” is subjective. Be specific—ask about material specs, hinges, coatings, etc.
Ignoring time zones	If you’re in the US or Europe, be aware that most China-based suppliers respond during Beijing Time (GMT+8).
Relying only on chat	Always summarize key agreements in writing (e.g., Proforma Invoice or email). Verbal messages via WhatsApp are risky.
Not confirming customization limits	Some suppliers may only offer logo printing, not full custom molds. Clarify this early.

 Pro Tip: A good supplier will reply within 24 hours, give detailed answers, and proactively ask about your target market and needs. If they don’t, consider moving on.

2.4 Build a Relationship, Not Just a Transaction

Especially for wholesale or repeat orders, treat communication as the foundation of a business partnership, not just a one-time purchase.

Here are ways to build long-term trust:

• Be responsive and clear in your replies
• Share feedback on samples or past orders
• Offer reasonable timelines and expectations
• Pay on time and maintain transparency

Suppliers like Eyewearglobo, who have years of export experience, often assign dedicated sales reps to long-term clients. This helps you avoid delays, miscommunication, or quality surprises down the road.

Step 3: Visit Eyewear Manufacturing Sites (If Possible)

If you’re planning to place a large order—or looking for a long-term TR90 eyewear supplier—it’s highly recommended to visit the manufacturer’s site in person or request a virtual factory tour. This step helps you verify the factory’s real capabilities, avoid “middleman” traps, and gain peace of mind before investing.

3.1 Take a Product Display Site Tour

Most established eyewear manufacturers in China have a product showroom or display area. Visiting this space allows you to:

• Examine their TR90 frame collections up close
• Touch and feel frame weight, flexibility, and texture
• See color options, lens finishes, and packaging styles
• Compare stock models vs custom design capabilities

You can also request to see past projects, including branded TR90 frames for other B2B clients. This helps you evaluate whether their style and quality match your brand’s needs.

3.2 Visit the Production Lines

A real factory visit (or live video walkthrough) gives you a clear picture of:

• Injection molding machines used for TR90 material
• Assembly processes – how frames, hinges, nose pads are fitted
• Quality control procedures – from raw material to final inspection
• Packaging and warehousing systems

This is especially important if you’re doing OEM (custom frame design) or high-volume orders. You’ll want to confirm that the supplier has the production capacity and equipment to meet your specs and deadlines.

 If visiting in person is not possible, ask the factory to provide:

• A pre-recorded video tour
• Live video call walkthrough on platforms like WeChat or Zoom
• Photos of machines, QC records, and packaging areas

3.3 What You’ll Gain from a Site Visit

Whether in person or virtual, this step helps you:

•  Validate that the supplier is a real manufacturer (not a trading company)
•  Understand production timelines and potential bottlenecks
•  Build trust with the sales team and management
•  Spot any red flags (outdated machinery, poor storage, low hygiene standards)

 Pro Tip: Factories like Eyewearglobo welcome both physical and online visits. Their 5 production lines are set up for both ready-stock and custom TR90 frame production, making them transparent and reliable partners for global B2B clients.

。

Step 4: Consider the Following Before Placing an Order

Before you place your first wholesale order for TR90 eyeglass frames from a Chinese supplier, take the time to double-check a few key points. These details will directly affect your product quality, delivery timeline, import clearance, and ultimately, your brand reputation.

Think of this step as your final risk control before you move forward.

 Check Product Certifications (CE, FDA, ISO)

Certifications aren’t just a “nice-to-have”—they’re often a requirement for import into your country.

Ask the supplier for:

• CE Certificate (for European Union markets)
• FDA Registration (for the U.S. market)
• ISO 9001 or ISO 13485 (for quality management)
• Material Safety Sheet (MSDS) or TR90 composition report

 Tip: Don’t just take their word for it. Request scanned copies of certificates with official stamps or serial numbers. Cross-check with public databases if needed.

 Understand the Supplier’s Export Experience

You want to work with a supplier who:

• Regularly ships to your region (e.g., North America, Europe, Southeast Asia)
• Understands export procedures, customs clearance, and packaging requirements
• Has experience working with eyewear wholesalers, retailers, or private brands

Questions to ask:

• “Which countries do you currently export to?”
• “Can you provide references or order history for international clients?”
• “Are you familiar with CE/FDA documentation for eyewear?”

 Experienced exporters will be able to guide you, not just follow instructions blindly.

 Assess Customization Capabilities

Even if you’re starting with ready-stock TR90 frames, sooner or later you’ll want to offer:

• Logo printing or engraving
• Custom colors or transparent finishes
• Packaging with your brand identity
• Custom lens options (for sunglasses or blue light protection)

Ask for:

• Their customization catalog
• Past samples they’ve done for other brands
• Minimum order quantities (MOQs) for OEM or private label projects
• Whether they offer 3D mockups or prototyping

 Not all suppliers are equipped for advanced customization. Factories like Eyewearglobo offer in-house logo printing, color matching, and even mold development for brand owners who want to stand out.

 Review the Final Product Specification Sheet

Before signing a PI (Proforma Invoice) or contract, make sure both sides have agreed in writing on:

• Frame model & size (e.g., 52-18-140)
• Frame material (100% TR90 or TR90 + metal)
• Color code or pantone
• Lens type (clear, demo, tinted, polarized)
• Logo printing details (location, method, color)
• Packaging (case, pouch, cleaning cloth, box)
• Lead time & shipping terms

 Having a spec sheet signed by both parties avoids disputes later on.

Step 5: Negotiate Pricing with TR90 Eyewear Suppliers

Once you’ve confirmed the TR90 frame specs, certifications, and customization needs, the next crucial step is to negotiate pricing. But pricing is more than just asking “How much?”—it’s about understanding the full cost structure, identifying hidden fees, and ensuring both sides are clear on what’s included.

Done right, this step can help you maximize your profit margin without sacrificing product quality.

 Ask for a Detailed Quotation

Don’t settle for a one-line price like:

“TR90 frames: $4.20/piece.”

Instead, request a quotation sheet (or Excel) that clearly outlines:

• Base unit price (e.g. per piece for 100/300/500 pcs)
• Logo printing fees (per logo or per mold)
• Lens upgrade costs (e.g., blue light lens, UV400, demo lens)
• Packaging options (case, pouch, microfiber cloth, box)
• Shipping method & cost estimate (if applicable)
• Free vs paid samples

 Pro Tip: Ask for tiered pricing (e.g., for 300, 500, and 1000 units). Many suppliers offer discounts at higher volumes, which helps you plan future scale.

 Clarify What’s Included (And What’s Not)

You don’t want surprises later. So confirm:

 Don’t Just Negotiate Price – Negotiate Value

A common mistake is focusing only on the lowest price, which often leads to:

• Low-quality TR90 alternatives
• Thinner frames that break easily
• Poor printing or color coating
• Delays due to lack of QC

Instead, aim for best value—reasonable price with guaranteed quality, responsive service, and on-time delivery.

If you plan to reorder in future, you can also ask for:

• Better terms for second or third order
• Free logo printing above certain quantity
• Free express sample for reorders

 Building a relationship with the supplier can give you negotiation leverage over time—especially when you become a repeat buyer.

 Example of a Smart Price Negotiation Email

Here’s a quick email template you can use:

Subject: Request for Detailed Quotation – TR90 Optical Frames

Hello [Supplier’s Name],

Thank you for your previous reply. Could you please provide a detailed quotation based on the following:

• Frame model: [Model Code or Sample Photo]
• Quantity: 500 pcs
• Logo: 1-color printed on temples
• Lenses: Clear demo lens
• Packaging: With case & microfiber cloth

Please break down the unit price, logo cost, packaging fee, and estimated lead time.

We are planning for long-term cooperation and may scale up in future orders. Looking forward to your best offer.

Best regards,
[Your Name]
[Company Name]

Step 6: Place an Order with the Manufacturer

Once you’ve agreed on the TR90 frame model, customization details, pricing, and lead time, it’s time to formalize your order. This step is all about locking everything in writing, so there’s no confusion between you and the supplier later—especially when production begins.

In international wholesale, verbal promises or casual chats are not enough. You need clear documentation to protect both sides.

 Use a Proforma Invoice (PI) or Sales Contract

Most Chinese suppliers will issue a Proforma Invoice (PI) for the order. This is not just a quotation—it’s a binding document that outlines everything you’re paying for.

Make sure the PI includes:

• Your company name & shipping address
• Supplier’s name, address, and contact info
• Order number & date
• Product details: model, color, size, TR90 material
• Quantity and unit price
• Total order value (with currency)
• Payment terms (e.g. 30% deposit, 70% before shipment)
• Delivery time (e.g. 30–45 days after deposit)
• Incoterms: EXW, FOB, or CIF
• Bank account info (confirm this carefully!)
• After-sales or warranty terms (if agreed)

 Tip: If the order is large or highly customized, you may want to sign a separate Sales Contract in addition to the PI. This offers stronger legal protection and can be drafted by your sourcing agent or legal team.

 Confirm Product Specifications in Writing

Don’t assume the supplier remembers every detail from your chat. The PI or contract should clearly specify:

 Pro Tip: Ask for photo confirmation or a sample before production starts, especially if you’re ordering a new design or color.

 Clarify Production Lead Time and Penalties

TR90 frames usually take 25–45 days to produce, depending on the quantity and customization level.

Make sure the PI or contract includes:

• Estimated production time
• Shipment deadline
• Any penalty clause (e.g., late by 10+ days = 2% discount or refund)

This will help you stay on schedule—especially if you’re aligning the delivery with a retail season or launch.

 Set the Payment Terms Clearly

The most common payment term for international eyewear orders is:

• 30% deposit before production
• 70% balance after QC inspection and before shipment

Make sure:

• The bank account name matches the supplier’s company name
• The currency is agreed upon (usually USD)
• You receive an official invoice or confirmation after each payment

 Warning: Double-check payment info over a video call or a second channel if the amount is large. Email hacks and fraudulent bank accounts do happen in international trade.

 Keep All Documents Organized

Create a folder (digital or printed) with:

• Quotation & PI
• Sample photos
• Email confirmations
• Payment receipts
• Inspection reports (if applicable)

This becomes your proof and protection if any disputes arise later.

Step 7: Make a Deposit

After you’ve signed the Proforma Invoice (PI) and confirmed all specs and timelines, the next step is to make the deposit—usually 30% of the total order amount. This is when the manufacturer officially schedules your production in their queue and begins preparing raw materials (TR90 pellets, molds, etc.).

But before you hit “Send” on your international transfer, it’s critical to verify everything carefully to avoid costly mistakes or fraud.

 Understand Standard Payment Terms

For wholesale TR90 eyewear orders, the most common payment term is:

• 30% deposit before production
• 70% balance after QC inspection and before shipment

Occasionally, for smaller ready-stock orders or repeat customers, some suppliers may accept:

• 50/50 terms
• Full payment in advance (not recommended unless supplier is well-known)
• Letter of Credit (L/C) – used in large corporate or government orders

 Tip: Always confirm that the supplier has officially received your deposit before assuming your order has started production.

 Use Secure and Verified Payment Channels

For your own financial safety, avoid informal payments or personal bank accounts.

The most widely used and secure methods include:

 Warning: Always confirm bank details via an official company email or phone/video call—not just chat. Email phishing scams that redirect payments are sadly common.

 What to Confirm Before Sending the Deposit

1. Company name on bank account matches the name on your PI or contract
2. Bank details are sent from official email (e.g., *@eyewearglobo.com)
3. Currency (USD, EUR, etc.) and amount match the PI
4. SWIFT code and bank address are provided
5. If using Alibaba, the supplier’s Trade Assurance account is active and tied to their company name

 Request a Payment Confirmation

After you’ve sent the deposit, ask the supplier to confirm:

• Amount received
• Date of receipt
• Estimated production start date and completion date

This helps you track the project timeline internally.

 You can send a simple confirmation email like this:

Subject: Payment Confirmation – TR90 Frame Order

Hello [Supplier Name],

Please note we have transferred the 30% deposit today.

Kindly confirm once received, and please update us on the estimated production schedule.

Best regards,
[Your Name]
[Company Name]

Step 8: Inspect the Product

Before making the final payment and shipping your TR90 eyewear frames, it’s essential to inspect the products—either by yourself, by a third-party quality control (QC) agency, or through the supplier’s internal QC team.

Skipping this step can result in:

• Receiving the wrong model or color
• Poor logo printing or missing branding
• Low-quality TR90 material (not flexible, too thin)
• Scratched lenses or packaging damage
• Entire batches needing to be reworked—or worse, discarded

In short, inspection helps you catch small problems before they become expensive ones.

 Option 1: Hire a Third-Party QC Company

If you’re not in China and want objective quality control, consider using a third-party inspection agency. These companies specialize in product checks at the factory before shipment.

Recommended QC providers:

• QIMA – www.qima.com
• SGS China – www.sgsgroup.com.cn
• AsiaInspection – Part of QIMA, also widely used in eyewear QC

What they typically check for TR90 frames:

• Frame model, size, and color match the PI
• Logo placement and clarity
• TR90 flexibility (bend test)
• Surface finish (smooth, no bubbles or scratches)
• Lenses are clean, intact, and correctly fitted
• Packaging as per agreement

 Most QC companies offer detailed inspection reports with photos, test results, and pass/fail notes.

 Option 2: Request Supplier to Provide Inspection Materials

If you’re working with a trusted supplier like Eyewearglobo, they may offer:

• Pre-shipment photos and videos
• QC checklist signed by the factory’s quality team
• Live video call inspection (via WhatsApp, Zoom, or WeChat)
• A few random samples shipped to you for final approval

This can be a cost-effective alternative, especially for repeat orders or lower-volume batches.

 What to Include in the Inspection Checklist

Whether it’s you, a QC team, or your supplier doing the inspection, make sure to check:

 Request “Golden Samples” for Reference

If you plan to reorder in the future, ask the factory to keep 1–2 pieces of the approved final product as “golden samples.” This ensures consistent quality for repeat orders.

 What to Do if Problems Are Found

If your inspection (third-party or internal) finds issues:

• Immediately notify the supplier in writing (with photos)
• Request rework or replacements before shipment
• Refer to the PI or contract for any penalty terms or compensation
• Never pay the final 70% until QC is passed and confirmed

 Warning: If the supplier pushes for final payment before QC—or refuses inspection—that’s a major red flag.

Step 9: Final Payment

Once your TR90 eyeglass frames have passed inspection, it’s time to make the final payment—usually the remaining 70% of the total order value. This is the last step before your goods are shipped, so it’s important to handle it carefully and document everything clearly.

 Confirm Inspection Approval Before Payment

Before you pay, double-check:

• You have received the final inspection report, with “Pass” status
• Product photos or videos match your specifications
• You’ve seen packaging details (carton markings, label placement, etc.)
• Any agreed corrections or rework have been completed

 If you’re using a third-party QC service, ask them to release the “shipment approval notice” to you directly.

 Review the Final Invoice

The supplier will typically issue a Final Commercial Invoice after inspection. Make sure it includes:

• Accurate quantities and product details
• Final unit prices and total amount
• Shipping terms (FOB, EXW, etc.)
• Bank account details
• Incoterms and payment terms
• Reference to your original PO or PI number

This invoice may also be used later for customs clearance, so accuracy is important.

 Use the Same Secure Payment Channel

Pay the remaining 70% through the same secure method you used for the deposit (usually T/T or Alibaba Trade Assurance).

Before you send the money:

• Re-confirm the bank account name and number (to prevent fraud)
• Ask the supplier to send a “bank account confirmation letter” with company chop
• Notify your bank of any currency conversion or SWIFT code requirements

 Security Tip: If you receive a last-minute email saying the bank account has changed—stop and verify by phone or video call. This is a common fraud tactic in international trade.

 Keep Records of the Payment

After sending the final payment, save the following documents:

• Bank remittance slip / transaction receipt
• Final invoice and PI
• Any email confirmations or delivery commitments

Also, ask the supplier to:

• Confirm receipt of the funds
• Share the estimated shipping date
• Provide the bill of lading info or courier tracking number (once available)

 What Happens After Final Payment?

Once payment is confirmed, the factory will:

1. Arrange shipping booking (if FOB/CIF terms)
2. Finalize packaging and labeling
3. Issue the necessary documents for export:
   • Packing List
   • Commercial Invoice
   • Certificate of Origin (if required)
   • CE/FDA documents (for customs)

Depending on your agreement, this process takes 3–7 days after final payment.

 Reminder: If you’re working with a supplier like Eyewearglobo, they will typically assist with all shipping documents and offer post-payment support, including logistics tracking and customs declaration help.

Step 10: Get Ready to Import TR90 Eyeglass Frames

After your final payment is completed, your supplier will begin preparing the shipment. But before your TR90 eyeglass frames are on the way, you need to make a few important decisions related to shipping and import logistics.

Your choices here will affect:

• Shipping cost
• Delivery speed
• Who’s responsible if something goes wrong in transit

Let’s break it down.

10.1 Choose Your Shipping Method

Depending on your order size, urgency, and budget, you can choose:

 Pro Tip: For TR90 frames in bulk, sea freight is the most cost-effective option, especially if your warehouse can handle long lead times.

10.2 Understand Incoterms: Who Handles What?

Incoterms (International Commercial Terms) define who is responsible for each part of the shipping process—from the factory to your warehouse.

Here are the two most common terms used in TR90 eyewear sourcing:

10.3 EXW – Ex Works

Under EXW, the supplier’s responsibility ends when the goods are ready for pickup at their factory.

You (the buyer) handle:

• Pickup from factory
• Export documents
• Customs clearance in China and at destination
• Full freight and insurance

Advantages:

• Full control over the shipping process
• Can negotiate better freight rates with your own forwarder

Risks:

• More work for you
• You must coordinate with a local Chinese freight forwarder

10.4 FOB – Free On Board

Under FOB, the supplier handles:

• Inland transport to port
• Export customs clearance
• Loading onto the ship/plane

You handle:

• International freight
• Import customs
• Final delivery to your warehouse

Advantages:

• Less stress and fewer unknowns on the China side
• Standard practice for many buyers

Risks:

• Freight rates may be slightly higher than EXW (but worth it for convenience)

 Most buyers prefer FOB when importing TR90 frames from China, especially for first-time orders.

10.5 Should You Use a Freight Forwarder?

Yes—especially if you’re importing via sea or air freight. A freight forwarder helps you:

• Book space on vessels or planes
• Prepare customs documents
• Handle insurance and duty estimation
• Coordinate delivery to your warehouse

You can either:

• Ask your supplier to recommend a trusted forwarder
• Use your own local freight agent who has China partners
• Work with global platforms like:
  • Flexport – Tech-enabled freight coordination
  • Freightos – Instant online shipping quotes
  • DHL Global Forwarding, C.H. Robinson, etc.

 Bonus Tip: If you’re importing to the USA, check if your forwarder offers bonded warehouse services for holding goods before duty is paid.

Step 11: Track Your Cargo While in Transit

Once your TR90 eyeglass frames have been shipped, it’s not the end—it’s the middle. Now comes the critical step of tracking your shipment to ensure that everything stays on schedule and arrives in good condition.

Whether you’re using air freight, sea freight, or express delivery, keeping a close eye on your cargo helps you plan for:

• Inventory readiness
• Customs clearance
• Warehouse scheduling
• Seasonal promotions or sales cycles

Here’s how to stay informed and in control.

 11.1 Get Tracking Information from Your Supplier or Forwarder

As soon as the goods leave the factory or warehouse, ask for the following (depending on the shipping method):

You can use these numbers to track the shipment on:

• Carrier websites (e.g., DHL.com, Maersk.com, CMA-CGM.com)
• Freight platforms like Flexport or Freightos
• Forwarder’s online dashboard, if available

 For sea freight, remember that updates may take longer (often updated every 1–2 days), so don’t panic if you don’t see movement immediately.

 11.2 Communicate with Your Freight Forwarder

Your freight forwarder should be your logistics partner, not just a service provider. Stay in contact with them to:

• Confirm the Estimated Time of Arrival (ETA)
• Get notified of any delays, port congestion, or customs inspections
• Prepare import documents ahead of time
• Coordinate last-mile delivery to your warehouse or fulfillment center

 A quick weekly check-in via email or WhatsApp is often enough during transit.

 11.3 Plan Ahead for Receiving the Cargo

To avoid delays or warehouse issues on your side:

• Schedule receiving staff ahead of time
• Notify your warehouse or logistics partner of the incoming goods
• Double-check your import paperwork:
  • Commercial invoice
  • Packing list
  • Certificate of origin (if needed)
  • CE/FDA certificates for customs

 If you’re using a bonded warehouse or Amazon FBA, be sure to follow their labeling and carton requirements exactly.

 11.4 Know What to Expect at Arrival

In all cases, you’ll be responsible for import taxes, duties, and any local delivery charges (unless agreed otherwise).

 Suppliers like Eyewearglobo often assist with document preparation to make customs clearance smoother.

Step 12: What to Do When the Product is Delayed or Damaged

Even with careful planning, international shipping can sometimes run into unexpected issues—delays, damages, or lost cargo. How you respond can determine whether the issue is a minor hiccup or a major financial loss.

Here’s a structured approach to help you handle such situations calmly and professionally.

 12.1 If the Shipment is Delayed

Delays can happen due to port congestion, customs inspections, extreme weather, or carrier scheduling issues. First, identify the type of delay:

 Pro Tip: Always build a 7–10 day buffer in your timeline if you’re importing TR90 frames for peak seasons or product launches.

 12.2 If the Product Arrives Damaged

Upon receiving the goods, always inspect immediately. Look for:

• Broken frames or bent temples
• Scratched lenses
• Faded or missing logos
• Damaged packaging or missing items
• Frames that are not TR90 (low-quality plastic substitutes)

 12.3 Document Everything

To file a claim or resolve the issue, you’ll need proof. Collect:

• Unboxing photos/videos (clearly show packaging condition)
• Close-ups of damaged items or incorrect models
• Copy of the packing list, invoice, and inspection report
• Description of how many pieces are affected
• If possible, keep the original cartons and labels untouched

 12.4 Communicate with Your Supplier Professionally

Send an email with:

• Order reference number
• Description of the issue
• Attached photos/videos
• Your preferred resolution (e.g., refund, credit, or replacement)

 Example:

Subject: URGENT: TR90 Frame Shipment – Damaged Goods Report

Hello [Supplier’s Name],

We have received our order (PI #12345), but unfortunately, we found that 70 units were damaged during transit (see attached images).

Please advise on how we can proceed with compensation or replacement.

We are happy to cooperate to resolve this professionally.

Best regards,
[Your Name]

 12.5 Possible Solutions

Depending on your agreement and the nature of the damage, your supplier may offer:

• Replacement goods in next shipment
• Partial refund or credit toward your next order
• Discount on balance payment (if damage was found before final payment)
• Insurance claim through the shipping carrier (if insured)

 Suppliers like Eyewearglobo typically offer a 3–6 month limited warranty, covering production defects under normal use. Be sure to clarify warranty scope before placing your order.

Step 13: Transport the Products to Your Warehouse

Once your TR90 eyeglass frames have cleared customs and arrived in your country, the final step is to move the goods from the port or airport to your warehouse (or to your fulfillment center, if you use 3PL services). Though this step may seem simple, handling it well ensures your inventory is safe, complete, and ready to sell.

 13.1 Plan Domestic Logistics in Advance

Whether you’re using sea freight or air freight, once the shipment lands, you usually have a limited free time window at the port or terminal (commonly 3–7 days). If you miss it, demurrage and storage fees can add up quickly.

So make sure to:

• Coordinate with your freight forwarder or customs broker to confirm release time
• Book local trucking or last-mile delivery to your warehouse
• Ensure your warehouse is ready to receive the goods (staff, space, unloading equipment, etc.)

 If you’re new to logistics, consider hiring a local delivery agent experienced in handling imported goods.

 13.2 Use a Bonded Warehouse (Optional)

If you’re importing a large quantity of TR90 frames and want to delay paying duties or split the shipment over time, consider using a bonded warehouse. This is a secure, government-supervised storage space where you can:

• Store your goods without paying import duty upfront
• Inspect the products before full release
• Ship out partial batches as needed

 Ideal for B2B distributors who resell frames under multiple brands or manage inventory seasonally.

 13.3 Inspect the Goods at Your Warehouse

Before shelving or shipping out your frames, conduct a final inbound inspection to ensure everything matches your expectations:

This is your last chance to catch any issues before the products go live for sale.

 Prepare for Sales or Fulfillment

Once the TR90 frames are stored safely:

• Update your inventory system with product SKUs, quantities, and batch info
• If you’re selling B2C, pass the stock to your eCommerce fulfillment center
• If you’re selling B2B, start preparing your catalogs, pricing sheets, and samples for retail partners or distributors

 At this point, you’re ready to start generating revenue from your order—the sourcing cycle is complete.

Step 14: Check for Warranty of the Eyeglass Frames

Even after your TR90 eyeglass frames have been delivered and stored, your responsibility as a buyer doesn’t end there—after-sales support matters just as much as the product itself. Whether you’re selling to optical shops, distributors, or direct-to-consumer channels, issues may occasionally arise.

A clear, reliable warranty policy helps you:

• Build trust with your downstream customers
• Handle complaints professionally
• Strengthen long-term partnerships with your supplier

Let’s go over what to check and how to handle after-sales support for TR90 frames.

 Confirm Warranty Terms Before Ordering

Ideally, warranty terms should be written clearly in your sales contract or PI. If not, ask your supplier questions like:

• Do you offer a warranty on TR90 frames?
• What does it cover? (e.g. material defects, color fading, loose hinges)
• What is the warranty period? (3 months? 6 months?)
• Does the warranty apply after the goods are received, or after they are sold to customers?

 Reminder: Many reputable Chinese eyewear factories provide a 3–6 month limited warranty covering manufacturing defects under normal usage conditions.

 Understand What the Warranty Typically Covers

While warranties vary between suppliers, most cover the following:

 How to Claim a Warranty (If Needed)

If you or your customer experience a problem with the product:

1. Document the issue clearly (photos, short videos if needed)
2. Reference the batch number or invoice number
3. Contact the supplier with a brief written explanation
4. Propose a fair solution:
   • Replacement in next shipment
   • Credit note for future orders
   • Partial refund (if agreed beforehand)

 Pro Tip: Be professional and constructive in tone. Suppliers are more likely to cooperate if they see you as a long-term partner rather than a one-time buyer.

• Full replacement or refund for frames with proven material or production defects

We aim to support our wholesale partners beyond the sale—because your success is our success.
