What documents and certifications does apparel export require?
Layer 1 — documents every shipment needs
- Commercial invoice — items, quantities and values. The basis for customs clearance and duty.
- Packing list — contents, counts and weights per box, used for inspection and clearance.
- Transport document — a bill of lading (B/L) for sea freight, an air waybill (AWB) for air.
- Korean export declaration — filed with Korea Customs, normally through a licensed customs broker.
The most common failure at this layer is not a missing document but a wrong HS code. Apparel splits into chapter 61 (knit) and chapter 62 (woven), then subdivides by fiber, gender and use. Get the code wrong and the duty rate and applicable regulations both change — fix it with a customs broker at the quoting stage.
Layer 2 — certificates of origin: where the duty is decided
A certificate of origin (C/O) proves where goods were made. A general C/O for origin marking and a preferential C/O for FTA duty savings are different documents, and preferential certification works differently under each agreement.
| Agreement | How certification works | Notes |
|---|---|---|
| Korea–US | Self-certification, no prescribed form | Exporter, producer or importer may certify |
| Korea–EU | Self-certification via an origin declaration on the invoice | Above EUR 6,000, only an approved exporter may declare |
| Korea–China | Issued by an authority | Chamber of commerce or customs office |
| RCEP · Korea–ASEAN | Authority-issued (RCEP also allows approved-exporter self-certification) | Common where production is split across Asia |
The trap: "sewn in Korea" does not automatically mean "Korean origin." Origin rules differ by agreement and product, and the origin of the fabric — even the yarn — affects the ruling. Under the Korea–US FTA, apparel generally follows a yarn-forward rule, meaning the yarn must originate in the region, so sewing imported fabric in Korea may not qualify. This is why origin should be assessed when fabric sourcing is decided, not after production.
One more caution: since 2025 the US has applied additional tariff measures separate from FTA rates, and the details keep changing. For US-bound orders, confirm the effective rate at the time of shipment with a customs broker before contracting.
Layer 3 — destination rules: labels and safety
| Market | What is typically required |
|---|---|
| US | Fiber content, origin and care labeling (FTC rules); for children 12 and under, CPSIA (lead and phthalate testing, certificate, tracking label); flammability standards |
| EU | Fiber-composition labeling, REACH restricted substances (azo dyes among others), safety standards for cords and drawstrings on childrenswear |
| Japan | Composition and care labeling under the household-goods quality labeling law |
The most expensive compliance mistake is fixing labels after production. Content wording, language and care symbols differ by market — lock the label text to the destination's rules before production and put it in the spec sheet.
Test reports and certifications — separating must from may
- Regulatory (mandatory) — tests the law requires, such as childrenswear safety and restricted substances, with reports from accredited laboratories. In Korea, institutes such as KOTITI, KATRI and FITI perform them.
- Buyer-required (contractual) — quality tests like colorfastness, shrinkage and pilling, run to the buyer's standard.
- Differentiators (voluntary) — product certifications such as OEKO-TEX Standard 100 (harmful-substance safety), GOTS (organic) and GRS (recycled content), and factory compliance audits such as BSCI, SEDEX and WRAP. Their absence does not block export, but some buyer groups — European retail in particular — make them a condition of trade.
The right time to test is after the fabric is confirmed and before bulk production. A failed test after bulk cannot be undone.
What is coming — the EU digital product passport (DPP)
Under the EU ecodesign regulation (ESPR), textile products are set to carry a digital product passport. The textile rules are expected to be adopted in 2027 and to apply after a transition period — realistically 2028 or later. It is not a document you need today, but the direction is fixed: material composition and supply-chain data attached at product level. Brands planning for the EU market should start organizing material and process data now. Attaching data to an individual garment is also the direction we have pursued with our sew-in RFID (RFID-X).
Who prepares what — buyer and manufacturer
In practice the split is clean. The manufacturer typically prepares the commercial invoice, packing list and certificate of origin (and maintains the bill of materials behind it), and cooperates on testing. Verifying destination rules and finalizing label text is usually the importer's responsibility. That is why the factory checklist tells you to verify export-documentation capability before ordering. Korean Friends has handled export procedures through its branch network in six countries — the US, China, Japan, Saudi Arabia, Vietnam and Indonesia — so production and export paperwork can run as one flow.
Frequently asked questions
Does sending a few samples require export formalities?
Simplified procedures exist depending on item and value, but "it's a sample" is not an automatic exemption. The US in particular ended its de minimis duty exemption in August 2025, so low-value shipments are subject to duty and formal entry regardless of value. Check with your courier or customs broker before shipping.
Who issues the certificate of origin?
Depending on the agreement, the exporter self-certifies or a chamber of commerce or customs office issues it. Either way, the manufacturer must maintain the bill of materials and origin records that make certification possible — verify this when selecting a factory.
Who pays for testing and certification?
There is no fixed rule — it is a contract matter. For legally required tests, writing who pays and at which stage into the order terms prevents disputes.
