Production know-how

We know which line works for hoodies, outerwear or denim — not just price tags.

What we source

Trims we specialise in

Zippers and metal hardware are where 70% of trim cost sits — and where most brands overpay. That's our focus.

About Japan Trim

We're not a vendor. We're your sourcing team.

Most brands assume their trims cost is fixed. It isn't. The same YKK zipper exists in different factories, different lines and different specifications — with prices that can vary by 10–30%, while looking and feeling identical to the end customer.

We work as an external BOM and supply-chain advisor. We sit between you and the YKK factories — finding the right line for the right product, at the right price, with the flexibility (MOQ, lead times) that direct sourcing rarely gives you.

  • BOM optimisation without touching brand quality
  • Alternative YKK lines — same brand, better economics
  • Flexible MOQ for growing collections
  • Built for 100–50000 unit production runs
