The Compliance Matrix by Market

Kids’ underwear is the most documentation-heavy category we supply: CPSIA for the US, EU GPSR for Europe, AS/NZS 1249 where sleepwear is involved. We assemble the compliance file per market at order stage, not at shipment. Category-level sourcing guides and the full product programme are linked below.

Multi-size assortments are planned with you at order stage: boys’ and girls’ styles can share prints and fabric lots, and packs are ratio-packed across the 2–16 size range to your market’s sell-through curve.

On the QC side, AQL 2.5 inspection is standard on kids’ orders, and metal detection can be added to the routine where your market or retailer requires it.

For retail programmes we coordinate hangtags, polybag printing and carton marks through the same order file, so packaging requirements such as fibre content and warning labels ship correctly with the goods.

Unitex runs its own liaison office in Jinjiang, on the ground inside the Fujian knitwear cluster, handling order follow-up, QC and factory audits.
