Why Cleared Apparel Still Can't Reach the Shelf
Importing Apparel & Textiles from China — Korea's KC Safety Compliance, Fiber Content, and Care Labeling Explained

Hello, this is GreenFrog Seoul.

"T-shirts don't need any certification — you just bring them in and sell them, right?"
"The factory said 100% cotton, so I just put that on the label, don't I?"
"Do I import baby clothes the same way as adult clothes?"

When certification comes up with clothing, most people think "surely it isn't that involved." There's no circuit board inside — it's just stitched fabric. But clothing touches your skin all day, and it can't leak harmful substances or bleed color after repeated washing. So Korea manages household textiles under the Electrical Appliances and Consumer Products Safety Act (the "safety act"). It doesn't mean you must slap on a visible KC mark, but there is a clear duty to meet safety standards and a duty to label in Korean. Miss this before you order, and you meet it later — as goods that cleared customs fine, yet can't be sold domestically.

Pin the big picture up front and it gets far less confusing. Importing apparel and textiles carries two kinds of homework. One is the product's own safety — did it meet the standards for formaldehyde, pH, and harmful dyes? The other is the label — are fiber content, country of origin, manufacturer/importer, size, and care instructions properly attached in Korean? On top of that sit items where the rules tighten a notch, like baby textiles for children 36 months and under, plus the customs-and-tariff side with HS codes and a Korea-China FTA certificate of origin. Today we walk through, in that order, what to confirm before you sell — from a buyer's perspective.

Having already covered the separate gate for food-contact products (#64) and KC certification for children's products (#65), today it's the turn of the clothes and fabric we wear every day. The labeling angle ties into #46 (Korean labeling & country of origin), so read them together.

1. Clothing Isn't "Just a Scrap of Fabric You Import"

Everyday textiles — T-shirts, knitwear, dresses, bedding — are classified under the safety act as safety-standard-compliance consumer products. The name is stiff, but unpacked it means this: you don't have the duty to get a certificate and attach a KC mark, but you absolutely must meet the safety standards the state has set. It isn't "no mark, so sell whatever you like." It's closer to "the mark is waived, but you meet the standards on your own."

So what gets checked? The items that flow from clothing's nature — it touches skin and must survive washing. The main ones addressed in the safety standards are formaldehyde (an irritant that can come from resin finishing and the like), pH (fabric that's too acidic or alkaline irritates skin), and dyes that release certain aryl-amines (so-called harmful azo dyes). The exact limits are set in the standards by product and target group, so here just hold the big frame: these items have to stay within the set limits.

2. Baby Textiles Are a Notch Stricter

The same garment tells a different story once it's a textile product for infants 36 months and under. Unlike adult clothing under safety-standard compliance, baby textiles generally fall under safety confirmation. In plain terms, that's a heavier gate: you pass testing at a lab, obtain KC certification (safety confirmation), and display it. The standards are stricter because it's the age when skin is delicate and clothes go into the mouth.

This is easy to confuse with children's products (#65), but the texture differs a little. Where children's products like toys and baby goods follow their own KC scheme, baby "textiles" follow a safety-confirmation requirement matched to the nature of fabric. Which requirement you take depends on the target age and product, so if you plan to bring in kids' or infant clothing, first settle whether your product ends at the adult standard or has to go all the way to infant safety confirmation.

3. The Label Is the Sales Condition — Korean Marking

Clothing is a classic category where perfectly good goods get blocked by the label alone. Even after clearing customs, to sell domestically you have to attach the required information in Korean. The items that matter most for textiles are these.

Miss even one of these and it can be a labeling violation. Fiber content and care symbols especially are what a consumer relies on to judge how to wash a garment, so getting them wrong goes beyond a clerical slip and can spill into consumer harm. Chinese factories often attach only their own label or an English care tag, but that doesn't substitute for Korean marking for the domestic market. Lock the label artwork in Korean before you order and hand it to the factory (#46).

4. What to Confirm When Talking to a Chinese Factory

In apparel sourcing, accidents cluster where the factory's words and reality diverge. Composition and color are especially hard to judge by eye. So pin them down not with words but with documents and testing.

Demand a test report on composition

Don't just trust the factory's spoken description of fabric composition — confirm it with a third-party lab report. That goes double for safety-related items like formaldehyde, pH, and harmful dyes. Instead of the phrase "100% cotton," ask for the test report run on that fabric, and the factory's level of preparation shows itself too. A factory that produces the report on the spot and one that talks around it part ways right here on trust.

Watch for declared-vs-measured fiber-content mismatches

The most common dispute is the gap between the declared fiber content and the measured value. The factory said "100% cotton," but it's actually a blend, or the declared ratio and the measured ratio don't line up. This sometimes stems from cost-cutting to lower the unit price, and sometimes crops up when the fabric lot changes. If the content on the label differs from the actual fabric, it becomes a false declaration, so you need a step that re-checks against the mass-production fabric.

Ask about dye fastness

A garment that bleeds color easily comes back as a claim after a single wash. Dye fastness — how well color holds against washing, rubbing, sweat, and light — tends to be weak in cheap fabrics especially. Confirm the fastness level before you order, and for a bright color or a dark shade worn with white, weigh the color-transfer risk in advance.

5. Import Practice — HS Codes, Tariffs, and the Korea-China FTA

With safety and labeling handled, next is the customs-and-tariff side. Apparel splits broadly into knit and woven, and the HS code splits here too. Knitted apparel falls under Chapter 61 and woven apparel under Chapter 62 as the basic skeleton. The same shirt gets a different code depending on whether it's knit or woven, and a different code means a different applied tariff rate.

The card to play here is the Korea-China FTA. Even for Chinese-made goods, if you meet the FTA's rules of origin and properly hold a certificate of origin (C/O), you can cut the duty burden with the preferential rate. The catch: it isn't "made in China, therefore automatically Chinese origin." You have to satisfy the rules of origin tied to the fabric and processing stages. Cases where the origin call splits — like fabric brought in from a third country and only sewn in China — really do come up.

At the clearance stage, an origin-marking check also happens. Customs looks at whether the origin marking on the garment meets the rules and whether the label's country of manufacture matches the paperwork. Mark the origin in a misleading way or leave it out, and it gets caught here and the goods stop.

6. This Is Where Sales Stop — Failure Patterns

Recurring accidents in apparel import mostly sort into a few patterns. These aren't about any particular company — read them as the general types that come up in the market.

What these patterns share is that the goods themselves look perfectly fine. The stitching is good and the design is nice, yet one of composition, label, or origin is off, so you can't sell. That's why with clothing, the accidents happen in "getting it sellable," not in "making it." The few days spent squaring safety standards, labeling, and origin before you order head off the accident where goods sit tied up in the warehouse after clearance.

7. Apparel & Textile Import Checklist

Safety standards and scope

• Settled whether my product is safety-standard compliance (adult) or infant safety confirmation
• Planned to secure test reports for safety items like formaldehyde, pH, and harmful dyes
• For infant items 36 months and under, booked KC certification (safety confirmation) schedule and cost separately

Labeling

• Locked the Korean label artwork with fiber content, origin, manufacturer/importer, size, and care instructions
• Set the spec so the label is attached to survive washing and not rub off
• Assumed Korean marking is needed for the domestic market, separate from the factory's English/Chinese label

Factory and customs

• Added a step to re-verify fiber content and dye fastness against the report and the mass-production fabric
• Confirmed HS classification (Ch. 61/62) and the applied tariff rate before ordering
• Checked whether the Korea-China FTA rules of origin are met and prepared the certificate of origin

Closing — With Clothing, "Making It" Is Easier Than "Getting It Sellable"

Today's content, compressed one line each:

• Safety: household textiles carry no KC-mark duty, but they're a safety-standard-compliance product that still must meet standards for formaldehyde, pH, and harmful dyes
• Infant: textiles for children 36 months and under generally fall under safety confirmation, a heavier gate that needs KC certification
• Label: fiber content, origin, manufacturer/importer, size, and care instructions must go on in Korean and survive washing before you can sell
• Factory talk: confirm composition with a test report, and watch declared-vs-measured fiber-content mismatch, dye fastness, and mass-fabric switches
• Customs: the HS code splits into Chapters 61 and 62, and meeting the Korea-China FTA rules of origin with a certificate of origin can cut duty

The substance of apparel import comes down to this: it's less about making the garment well and more about getting that garment ready to sell in Korea. The few days spent squaring composition, label, and origin before you order later head off goods stuck after clearance and recalls of stock already brought in. If you're preparing T-shirts, knitwear, or kids' clothing and can't tell which safety standard and marking to take, feel free to reach out. From checking safety standards to reviewing test reports, producing the Korean label, and pre-shipment inspection, we'll help in one flow.
