Custom Underwear for the Japanese and Korean Market in Viscose with Tie-Dye Wash for East Asian Corporate Uniforms

Custom Underwear for the Japanese and Korean Market — Viscose with Tie-Dye Wash

We supply underwear to japanese and korean buyers built for cold Korean winters. Cloth weight, weave openness and colour fastness are specified for the climate first: Viscose at 160-200 gsm, shade-matched to hold through the Korean back-to-school season. Programmes start at 500 pieces per style per colour and ship to Tokyo or Osaka.

The failures here are predictable: minimum order quantities far above what a growing brand can absorb, and inconsistent sizing between production runs. 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

Korean KC safety certification for textiles 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

What is the minimum order quantity?

Standard programmes start at 500 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.

How long does sampling take?

A first prototype is typically ready in 10 working days after the tech pack is confirmed, including fabric sourcing if the base cloth is not in our stock library. Revisions add about 5 days each.

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.
