Custom T-Shirt for the Japanese and Korean Market — Organic Cotton with Custom Button
We supply t-shirt to japanese and korean buyers built for cold Korean winters. Cloth weight, weave openness and colour fastness are specified for the climate first: Organic Cotton at 210-260 gsm, shade-matched to hold through the Korean back-to-school season. Programmes start at 100 pieces per style per colour and ship to Busan.
The failures here are predictable: inconsistent sizing between production runs, 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 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 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
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 is the minimum order quantity?
Standard programmes start at 100 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.
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.
