Custom Boning — PU Leather with Ultrasonic Welding
We supply boning to garment factories and brands, built in PU Leather with ultrasonic welding for childrenswear and schoolwear. On a trim like this the specification that decides the outcome is tip finishing, which decides whether it wears through the casing, so that is agreed in writing before bulk — not discovered when the first carton is opened on the line. Programmes start at 3000 pieces per style per finish.
The failures here are predictable: unclear responsibility when a defect shows up after washing, or inconsistent sizing between production runs. We lock material, finish, dimension and tolerance before bulk, and prepare CPSIA and California Prop 65 compliance so the shipment clears instead of sitting at port while your selling season passes.

Where it is used
- Denim and workwear — hard-wearing finishes that survive industrial washing
- Outerwear and tailoring — matched to the shell fabric so it drapes with the garment
- Childrenswear and schoolwear — tested to the destination's safety standard
- Bridal and eveningwear — small runs with hand-finished detail
- Uniform and corporate programmes — repeatable spec held on file for reorders
Packing, testing and delivery
Trims are packed to the ratio you specify — by size, by colour or by garment set — with barcodes applied where the line needs them. Test reports for GRS recycled content claim are prepared for the destination market. We ship to Los Angeles or New York with the commercial invoice, packing list and certificate of origin, and hold the approved reference so reorders reproduce the same material, the same finish and the same tip finishing.
FAQ
Can you do small runs across many designs?
Yes — many studio and boutique programmes run small quantities across a wide design set.
Can you match a reference sample?
Yes. Send the trim and we match material, finish and shade, then confirm on a pre-production sample before bulk.
How do you control colour on reorders?
The approved reference and the bulk standard are retained, and every reorder is checked against them before shipment.
Which compliance documents do you provide?
We prepare GRS recycled content claim and the supporting test reports for the destination market.
