Custom Underwear for the Japanese and Korean Market — Antibacterial Knit with Woven Label
We supply underwear to japanese and korean buyers built for East Asian rainy season. Cloth weight, weave openness and colour fastness are specified for the climate first: Antibacterial Knit at 160-200 gsm, shade-matched to hold through the Japanese gift-giving season. Programmes start at 100 pieces per style per colour and ship to Incheon.
The failures here are predictable: color drift between lab dips and bulk fabric, and inconsistent sizing between production runs. We lock the specification before bulk — weight, shrinkage, stitch density and tolerance — and prepare the conformity documents for Korea so containers clear instead of accruing demurrage while the Japanese gift-giving season passes.

Import, duty and delivery
Korean KC safety certification for textiles is arranged before the goods leave the factory. We ship to Incheon with the commercial invoice, packing list and certificate of origin. Buyers here inspect to a tighter standard: needle detection, dimensional stability after washing and seam appearance are checked before packing, and labelling follows the Household Goods Quality Labelling rules rather than a generic care tag.
FAQ
What file formats do you need for artwork?
Vector files (AI, EPS, PDF) give the best print and embroidery results. For raster artwork please supply at least 300 dpi at the final print size. We digitise embroidery files in-house and return a sew-out photo for approval.
Can you match a specific colour?
Yes. Send us a Pantone TCX reference or a physical swatch. We return lab dips for approval and hold bulk shade within the agreed tolerance band before cutting.
Do you provide compliance documents?
We can arrange OEKO-TEX, GOTS, BSCI, WRAP and ISO documentation as well as third-party testing reports for GRS recycled content claim, and we support REACH, CPSIA and Prop 65 declarations for the relevant markets.
How is shipping handled?
We quote EXW, FOB, CIF and DDP. Consolidated sea freight is the default for bulk programmes, with air or express options when a launch date is at risk.
