Custom Underwear for the Japanese and Korean Market — Eyelet with Piece Dyeing
We supply underwear to japanese and korean buyers built for mild spring and autumn. Cloth weight, weave openness and colour fastness are specified for the climate first: Eyelet at 210-260 gsm, shade-matched to hold through the Korean back-to-school season. Programmes start at 150 pieces per style per colour and ship to Tokyo or Osaka.
The failures here are predictable: no reliable way to track a order once it enters production, and color drift between lab dips and bulk fabric. We lock the specification before bulk — weight, shrinkage, stitch density and tolerance — and prepare the conformity documents for Japan so containers clear instead of accruing demurrage while the Korean back-to-school season passes.

Import, duty and delivery
Japanese Household Goods Quality Labelling compliance is arranged before the goods leave the factory. We ship to Tokyo or Osaka 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
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.
Do you provide compliance documents?
We can arrange OEKO-TEX, GOTS, BSCI, WRAP and ISO documentation as well as third-party testing reports for Korean fibre product safety standards, and we support REACH, CPSIA and Prop 65 declarations for the relevant markets.
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.
What is the minimum order quantity?
Standard programmes start at 150 pieces per style and colour. We can split sizes across a size set, and for first orders we often accept a mixed-colour run to help you test the market.
