Search how to sell sunglasses from China and you get import guides that list standards, a compliance site with a wall of rules, and supplier blogs promising "UV400, FDA, CE" on every pair. None of them tells a Shopify brand what each of those words is worth, what its own box and product page have to show, or which line a pair travels on.

The short answer: sunglasses ship on the general goods products that parcel lines out of China run, so the shipping is the easy part. The work is proof. In the US, sunglasses count as a medical device, the lowest class, and every lens has to pass an impact test, done on a sample of each production batch. In the EU, sunglasses are protective equipment: the pair carries the CE mark, its lens category, your name and address, and instructions in the buyer's language.

This guide covers:

• What "FDA approved", "UV400", "polarized" and "CE" on a factory listing are worth
• The US impact test, and the records to ask the factory for
• The EU lens categories, and the driving warning that goes with them
• What the box, the frame and your product page have to show
• Which line sunglasses go on, and how long they take

What the claims on a factory listing are worth

A sunglasses listing from a Chinese factory usually carries the same row of words. Read them like this:

• "FDA approved". The FDA does not approve sunglasses. They are a Class I medical device, exempt from premarket review. What exists is a duty: the factory registers with the FDA and lists its products, and the lenses pass an impact test.
• "UV400". A seller's term, generally used to mean the lens blocks ultraviolet light up to about 400 nanometres. It is not a category in the US rule or the EU standard. Ask for the test report and check it shows the UV transmittance for your lens.
• "Polarized". A real lens type that cuts glare off water and roads. It is a claim like any other, so it should be in the test report, not only on the listing.
• "CE". In the EU, the brand that sells the pair is treated as the manufacturer and signs the declaration. A CE mark printed by the factory does not make the declaration yours.

The useful question is "which lens is this, what was it tested against, and can I see the report for this batch?". The guide to verifying a Chinese supplier covers checking the company behind the answer, and the guide to ordering product samples from China covers getting a pair in hand before you order.

The US impact test, and the records to ask for

Under 21 CFR 801.410, sunglasses sold in the US must have impact-resistant lenses. The test is a drop ball test: a steel ball about 16 mm across, about 16 grams, dropped from 127 cm (50 inches) onto the centre of the lens. The lens must not break.

Three things make this practical for a brand:

• The test runs on every batch. For plastic lenses, the manufacturer tests a statistically significant sample from each production batch. A report from last year's run does not cover this year's.
• The records are kept for three years. Test results, the method and the apparatus, ready to show the FDA on request. Ask the factory for the record for your batch, not a general certificate.
• The factory is registered. Foreign manufacturers register their establishment with the FDA, name a US agent and list their devices. You can look a factory up in the FDA's public registration and listing database.

The voluntary US standard for sunglasses, ANSI Z80.3, adds optical and UV tests on top. It is worth asking for, but it is not the legal minimum. Sunglasses for children can also count as a children's product, with the lab test and certificate in the guide to selling toys from China. This is a summary, not legal advice; an optical test lab can tell you which tests your range needs.

The EU lens categories, and the driving warning

In the EU, sunglasses are personal protective equipment under Regulation (EU) 2016/425, in the lowest risk group: protection from sunlight. That means no outside body has to check them. The brand runs its own checks, holds the technical file and the EU declaration of conformity for 10 years, and puts the CE mark on the pair.

The harmonised standard, EN ISO 12312-1, sorts every lens into one of five filter categories by how much light gets through:

For everyday sun, those uses point to category 2 or 3. Category 4 lenses, the darkest, are not suitable for driving at any time, and the pair has to say so. Darker lenses are generally not for driving at dusk or at night either. The category is marked on the frame, usually after "cat.", and goes in the instructions.

What the box, the frame and your page have to show

Under the PPE Regulation, a pair sold in the EU carries:

• The CE mark, often on the inside of the frame
• A type, batch or serial number, on the pair or on the packaging when it will not fit
• Your name, trade name or trade mark and a postal address, on the pair, the packaging or a document that comes with it
• Instructions and information in a language the buyer understands, including the filter category, the driving warning and care notes

This is where most pairs fail. In 2024, one Czech regional inspectorate found faults in about two in three sunglasses types it checked, and the most common ones were paperwork: no instructions or none in Czech, no name and address, no declaration of conformity.

The product page has its own rule. Since 13 December 2024, the EU's General Product Safety Regulation asks every online offer to show the manufacturer's name and contact details, an EU responsible person when the manufacturer is outside the EU, a picture of the product and its warnings. For sunglasses, put the filter category and any driving warning in the description, near the top, in the same words as the leaflet. This is a summary, not legal advice.

Which line sunglasses go on

Parcel lines out of China run separate products by goods class, and a parcel goes on the one its contents allow. YunExpress, a frontier line, runs a general "Economy, Unrestricted" product beside its "Economy with Battery" product. SDH, a lowest-cost line to the US, runs general goods, battery and sensitive goods lines.

• Sunglasses, cases, cleaning cloths and cords ship as general goods.
• Audio glasses, smart glasses and anything with a light or a charger carry a battery and follow the rules in the guide to shipping products with batteries from China.
• Magnetic clip-on lenses can be treated as sensitive goods because of the magnets. Ask the line first.

A hard case protects the lenses but adds size, and on lines that bill the greater of scale and volumetric weight, size can cost more than weight. The rules are in the guide to custom packaging for products shipped from China.

How long sunglasses take from China

Sunglasses orders are too small a set to give them a figure of their own, so the times here are for the line products they travel on. On YunExpress to the US, parcels with a first carrier scan in August 2026, the per-store median on the general goods Economy product ran 8.9 to 18.7 days, and 9 in 10 parcels arrived within 12.1 to 21.6 days depending on the store. On SDH, a lowest-cost line, the general goods product ran 14.3 to 15.2 days. Audio glasses on the YunExpress battery product ran 11.0 to 14.0 days.

Sunglasses sell most in spring and summer, so stock and testing for the season are worth starting in winter, before the factories close for Chinese New Year.

What to do

• Ask for the drop ball test record for your batch, not a general certificate, and check it names your lens
• Look the factory up in the FDA's registration and listing database
• Ask for the UV transmittance in the report before you write "UV400" or "100% UV protection" on the page
• Check the filter category of every lens and colour, and print the driving warning on anything in category 4
• Hold your own EU declaration of conformity, with the CE mark, a batch number and your name and address on the pair or the box
• Put the instructions in the buyer's language, and the category and warnings in the product description
• Sort your range by goods class: general, battery (audio and smart glasses), or check first (magnets)

How we handle this at Commercive

Commercive is your all in one sourcing and fulfilment partner. We source from a product link or a photo across our vetted factories, or work with the supplier you already use, and we test products without holding you to the factory's minimum, which suits a sunglasses store trying a few frames and lens colours before it commits.

Your stock is received on our floor in China, and every order ships on the line that fits the product and the destination: a general goods line for sunglasses and cases, a battery line for audio and smart glasses, and a check with the line before anything magnetic goes out. Each parcel's scans sit in our dashboard. We recommend frontier lines such as YunExpress to essentially everyone; a lower-cost line might suit low-price frames with patient customers. Our measured delivery times by line and country are on our shipping status page.

If you're currently running a brand, just give us the product and your daily order volume. We'll get you a quote within the next 24 hours to hold up against what you're paying today.

Where these numbers come from. The US rules are from 21 CFR 886.5850 (sunglasses as a Class I device, exempt from premarket notification), 21 CFR 801.410 (impact-resistant lenses and the drop ball test) and the FDA's page on sunglasses, spectacle frames and lenses (registration, listing and labeling), read 30 October 2026. The EU rules are from Regulation (EU) 2016/425, Annex I and Articles 8 and 19, read 30 October 2026, with the EN ISO 12312-1:2022 filter categories and the 2024 inspection results as published by the Czech Trade Inspection Authority, and the category uses as published by the Norwegian Directorate for Civil Protection. This is a summary, not legal advice. Line product names are the carriers' own. Delivery times are our own measurement: parcels to the US from stores we fulfil from China, first carrier scan 1 to 31 August 2026, test stores excluded, calendar days from the first scan to the first delivered scan, measured 30 October 2026, shown as the range of per-store medians and 90th percentiles for stores with at least 30 delivered parcels on that line product.

Do sunglasses need FDA approval to sell in the US?

No. The FDA does not approve sunglasses. They are a Class I medical device, exempt from premarket review, but the lenses must pass the FDA's impact test, done on a sample of each production batch, and the factory has to be registered with the FDA and list its products.

What is the drop ball test for sunglasses?

It is the impact test in 21 CFR 801.410. A steel ball about 16 mm across, about 16 grams, is dropped from 127 cm onto the centre of the lens, and the lens must not break. For plastic lenses the manufacturer tests a sample from each production batch and keeps the records for three years.

What does UV400 mean on sunglasses?

It is generally used to mean the lens blocks ultraviolet light up to about 400 nanometres. It is a seller's term, not a category in the US rule or the EU standard, so ask for the test report and check it shows the UV transmittance for your lens before you put the claim on your page.

What do the sunglasses categories 0 to 4 mean?

They are the EU filter categories in EN ISO 12312-1, by how much light the lens lets through: category 0 lets through 80 to 100%, category 2 lets through 18 to 43%, and category 4 only 3 to 8%. Category 4 is for high mountains and the sea and is not suitable for driving.

Do sunglasses need a CE mark to sell in the EU?

Yes. Sunglasses are protective equipment under Regulation (EU) 2016/425, in the lowest risk group, so the brand runs its own checks, signs an EU declaration of conformity and puts the CE mark on the pair, with a batch number, its name and address and instructions in the buyer's language.

How long do sunglasses take to ship from China to the US?

About as long as other general goods on the same line. On YunExpress in August 2026, the per-store median on the general goods product ran 8.9 to 18.7 days from the first carrier scan to delivery, and a lowest-cost line took 14.3 to 15.2 days.
