Sourcing Sunglasses From China: FDA Impact Rules, QC and Packing
Quick answer: Sunglasses are light, cheap to ship and easy to brand, which makes them a classic China-sourced product. They are also medical devices in the US. The FDA classifies non-prescription sunglasses as Class I devices, and every lens sold in the US must be impact-resistant under 21 CFR 801.410, proven by a drop-ball test on samples from each production batch. An importer who resells sunglasses counts as the "manufacturer" for this rule, and a shipment without a test certificate can be held. On top of that, "UV400" and "polarized" are claims you must be able to prove, and children's sunglasses need third-party lead testing. Get the paperwork first, then check every batch.
What US rules apply to sunglasses
| Requirement | What it means | Who handles it |
|---|---|---|
| Impact-resistant lenses (21 CFR 801.410) | Lenses must survive a 5/8-inch steel ball dropped from 50 inches without fracturing. Plastic lenses are tested on a statistically significant sample from each batch; glass lenses are tested one by one. | Factory tests; the importer for resale is treated as the manufacturer and keeps the records |
| Drop-ball test certificate | A certificate with each shipment stating the lenses were tested under 801.410, with test records kept for 3 years | Supplier provides; importer holds and supplies to FDA on request |
| FDA establishment registration | Foreign manufacturers must register with the FDA and list their devices; initial importers in the US register too | Factory and US importer |
| UV and polarization claims | Any claim on the label or listing must be accurate and supported by testing | Seller |
| Children's sunglasses | Third-party lead testing at a CPSC-accepted lab, a Children's Product Certificate and tracking labels | Importer or US brand |
Two common misunderstandings. First, there is no such thing as "FDA-approved" sunglasses: non-prescription sunglasses are exempt from premarket review, and FDA registration is not an approval. A listing that says "FDA approved" is usually exaggerating a factory registration. Second, the impact rule is not optional for fashion glasses. Cheap novelty frames still need impact-resistant lenses.
Choosing frames and lenses
Materials decide durability, weight and how easily you'll pass the impact test:
- Lenses. Polycarbonate is light and naturally impact-resistant, which makes it the easiest choice. TAC (triacetate) is the usual material for cheap polarized lenses; ask for test results. Avoid glass lenses for online sales: they're heavy, break in transit and each one must be tested individually.
- Frames. TR90 nylon is flexible and light, good for sports and kids. Injection-molded plastic is cheapest. Acetate looks premium but costs more and needs careful polishing. Metal frames need solid hinges and nose pads.
- Coatings. Mirror and gradient coatings sell well in photos but can peel or scratch. Ask about the coating process and check it on samples.
- Hinges. Spring hinges survive daily use far better than basic barrel hinges. Loose screws are one of the most common complaints.
Documents to ask for before you order
- Drop-ball test report and certificate covering your lens type, with the batch or lot number. You need one for each shipment, not one from three years ago.
- UV transmission test to a recognized sunglass standard, such as ANSI Z80.3 in the US or ISO 12312-1, if you plan to claim UV400 or 100% UV protection.
- Polarization test if you sell polarized lenses.
- The factory's FDA registration number. Check it yourself in the FDA's public registration and listing database, and make sure the company name matches.
- For kids' styles: lead test reports from a CPSC-accepted lab for the frame, hinges, nose pads and any paint, plus the information you need for a Children's Product Certificate. Children's sunglasses have been recalled several times for lead in surface paint, and since July 2026 the CPSC requires most import certificates to be filed electronically at entry.
If a supplier can't produce a recent drop-ball certificate, move on. It's the first document the FDA will ask for.
Quality checks for each batch
Paperwork proves the design. Inspection catches the bad units in this particular batch. For sunglasses, check:
- Lens surface. Scratches, bubbles, waves (look at a straight line through the lens) and coating peel at the edges.
- Polarization. Look at a phone or laptop screen through the lens and rotate the glasses. Polarized lenses darken the screen at one angle. Mark every pair that doesn't.
- UV claims. A handheld UV transmission meter is inexpensive and quickly exposes fake UV400 lenses. Spot-check a few pairs per batch.
- Fit and alignment. Set the glasses on a flat table; both temple arms should touch. Lenses should sit level and secure in the frame.
- Hinges and screws. Open and close several times; check that screws are tight and spring hinges return.
- Branding. Logo print or laser marks on the temple should be sharp, centered and not rub off with a thumb.
- Accessories. Case, cloth and pouch present, clean and the right color.
We inspect 20% of every batch free at our Xinxiang warehouse. Extra inspection is $7 per person per hour if you want every pair checked. Our product inspection page explains the process.
Packing sunglasses for shipping
- Sleeve every pair. A soft poly or microfiber sleeve stops lenses rubbing on the case.
- Choose the case on purpose. A hard case protects best but makes the parcel bigger and heavier. A soft pouch in a padded mailer is cheaper to ship; a hard case is worth it for premium pricing and gifts.
- Protect against crushing. A pair in a pouch inside a plain poly mailer can be crushed in a sorting machine. Use a padded mailer or a small box.
- Brand the unboxing. A printed case, a logo cloth and an insert card make a $15 pair feel like a brand. See packaging and branding for options.
Worked example: a private-label launch
Say you order $2,000 of polarized sports sunglasses with your logo on the temples, plus branded hard cases and cloths:
- Sourcing fee: 10% in the first tier plus 2.5% for private label = 12.5%, so $250.
- Inspection: 20% checked free. To check every pair for polarization and lens defects, two inspectors for four hours is 8 × $7 = $56.
- Pick and pack: on a day with fewer than 20 orders, one pair is $2.00 per order; if the case is stocked as its own SKU, the order is $2.00 + $1.00 = $3.00.
- Storage: free for the first 2 months, and free while orders are moving.
Product cost, packaging, shipping and US duties are added at cost. Parcels from China pay US duties whatever their value now, so price on landed cost. Full rates are on our pricing page, and our private label guide covers the branding side.
How PackQuay helps
We source sunglasses from Chinese factories, ask suppliers for drop-ball, UV and registration documents before you order, and check incoming batches at our own warehouse. We can add your logo, cases, cloths and insert cards, and pack each pair so it arrives unscratched. We don't issue certifications, but we'll tell you which documents are missing before your money is committed. Send your styles on WhatsApp.
FAQ
Do sunglasses from China need FDA approval?
No approval exists for non-prescription sunglasses, but they are FDA-regulated Class I medical devices. Lenses must pass the impact-resistance drop-ball test, the factory must be FDA-registered, and each shipment should come with a test certificate.
What is the drop-ball test for sunglasses?
A 5/8-inch steel ball is dropped from 50 inches onto the center of the lens, which must not fracture. Plastic lenses are tested on a statistically significant sample from each batch, and glass lenses are tested individually.
Who is responsible for the impact test when I import sunglasses?
Under the FDA rule, an importer who resells sunglasses is treated as the manufacturer. The test can be done in China, but you must hold the certificate and records and be able to give them to the FDA on request.
How can I check if sunglasses are really polarized or UV400?
Look at a phone or laptop screen through the lens and rotate it; polarized lenses darken it at one angle. For UV400, ask for a lab report and spot-check samples with a handheld UV transmission meter.
Do kids' sunglasses have extra rules?
Yes. Sunglasses designed mainly for children 12 and under are children's products, which need third-party lead testing at a CPSC-accepted lab, a Children's Product Certificate and permanent tracking labels.
