Waterproof Zipper Sourcing Program for Denim Mills
Waterproof Zipper Programme for Denim Mills
This programme covers the full path from a waterproof zipper requirement to a repeatable bulk supply for denim mills. Instead of buying whatever a catalogue happens to stock, you specify the base material, the 3# Gauge, the finish and the packing, and we hold that specification so every reorder matches the last one.
The most common failure in waterproof zipper sourcing is not price — it is drift. A base material changes mill, the shade moves, a plating bath changes and the item quietly stops matching the approved sample. We prevent that with a written spec, an approved counter sample and a golden sample retained at the factory.
What the programme covers
- Specification build from your tech pack or a physical reference sample
- Base material and finish options with costed alternatives
- Sampling, testing and approval against EN 71-3
- Bulk production with in-line inspection and photo reporting
- Packing, documentation and shipment under the agreed Incoterm
Recommended specifications
- TPU — used when strength and abrasion resistance come first
- PU Leather — best balance of cost, availability and test performance
- Cotton — chosen when the item has to survive repeated laundering
- Genuine Leather — best balance of cost, availability and test performance

FAQ
How long does sampling take?
7 working days for the first sample, with 3 days per revision round. Plated or dyed-to-match items add a few days.
Which compliance documents do you provide?
EN 71-3 documentation is issued with the shipment. Test reports can be ordered against any additional standard you nominate.
Do you hold stock for reorders?
Approved specifications are kept on file and, for repeat programmes, base material can be reserved against a rolling forecast.
Can you handle our own artwork or tooling?
Yes. Artwork files or existing tooling can be used; we confirm tolerances in writing before the first production run.
Share the programme details and we will propose two alternatives — one optimised for unit cost, one for lead time — and let you choose.
