Custom Underwear for the Japanese and Korean Market in Poplin with Dye-Sublimation Printing for East Asian Corporate Uniforms

Custom Underwear for the Japanese and Korean Market — Poplin with Dye-Sublimation Printing

We supply underwear to japanese and korean buyers built for heated indoor environments. Cloth weight, weave openness and colour fastness are specified for the climate first: Poplin at 120-150 gsm, shade-matched to hold through the rainy-season quick-dry demand. Programmes start at 500 pieces per style per colour and ship to Busan.

The failures here are predictable: color drift between lab dips and bulk fabric, and packaging that arrives crushed and unsellable. 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 rainy-season quick-dry demand passes.

Import, duty and delivery

Japanese Household Goods Quality Labelling compliance is arranged before the goods leave the factory. We ship to Busan 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

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 long does sampling take?

A first prototype is typically ready in 14 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.

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.

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.
