Nylon Zipper for a Sportswear Brand in Switzerland
A Sportswear Brand approached us with a nylon zipper requirement for the Switzerland market. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive freight and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.
The challenge
- A spec that lived in an email instead of a tech pack
- A compliance document that arrived after the goods were already shipped
- Cartons packed to the factory ratio instead of the buyer's size ratio
What we specified
| Item | Nylon Zipper |
|---|---|
| Client type | A Sportswear Brand |
| Market | Switzerland |
| Order volume | 10,000 pieces across 4 specifications |
| Base material | TPU |
| Standard size | 5# Gauge |
| Finish | Epoxy Doming |
| Sampling rounds | 2 |
| Delivery window | 8 weeks from PO to ex-factory |
| Compliance | California Prop 65 |
How it was resolved
- We rebuilt the specification around TPU and locked the tolerance before bulk.
- The finish was moved to Epoxy Doming after strike-off tests showed better durability.
- A pre-production sample was approved and retained as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and ratio specification.
Result
- 10,000 pieces delivered inside the 8-week window.
- Unit cost held within 3.0% of the original quotation.
- Inspection-related rejection stayed under 1.5%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Approve a pre-production sample made from the actual bulk base material. Substitute material behaves differently in finishing.
