Custom Boning — PU Leather with Hard Enamel Fill
We supply boning to garment factories and brands, built in PU Leather with hard enamel fill for denim and workwear programmes. On a trim like this the specification that decides the outcome is spring-back, because boning that takes a permanent bend is scrap, so that is agreed in writing before bulk — not discovered when the first carton is opened on the line. Programmes start at 5000 pieces per style per finish.
The failures here are predictable: unclear responsibility when a defect shows up after washing, or colour drift between the approved sample and the bulk trim. We lock material, finish, dimension and tolerance before bulk, and prepare GB 18401 safety classification with GB/T 29862 fibre labelling 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 salt spray test for metal finishes are prepared for the destination market. We ship to Shanghai or Shenzhen 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 spring-back.
FAQ
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.
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.
Which compliance documents do you provide?
We prepare salt spray test for metal finishes and the supporting test reports for the destination market.
