Custom Underwear for the Japanese and Korean Market in UPF 50+ Sun Fabric with Piping and Binding for Japanese Retail and Select Shops

Custom Underwear for the Japanese and Korean Market — UPF 50+ Sun Fabric with Piping and Binding

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: UPF 50+ Sun Fabric at 90-120 gsm, shade-matched to hold through the spring and autumn new-arrival window. Programmes start at 300 pieces per style per colour and ship to Tokyo or Osaka.

The failures here are predictable: long lead times that miss the selling season, 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 spring and autumn new-arrival window passes.

Import, duty and delivery

JIS textile testing documentation 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 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.

What is the minimum order quantity?

Standard programmes start at 300 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 7 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.

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.
