Waterproof Zipper for a Workwear Distributor in Egypt
A Workwear Distributor approached us with a waterproof zipper requirement for the Egypt 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
- Shrinkage that only showed up after the first wash
- An interlining that bubbled after the first press
- Elastic that lost recovery after three washes
What we specified
| Item | Waterproof Zipper |
|---|---|
| Client type | A Workwear Distributor |
| Market | Egypt |
| Order volume | 10,000 pieces across 2 specifications |
| Base material | Iron |
| Standard size | 10# Gauge |
| Finish | Brushed Silver Finish |
| Sampling rounds | 2 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | GB 18401 |
How it was resolved
- We rebuilt the specification around Iron and locked the tolerance before bulk.
- The finish was moved to Soft-Touch Rubber Coating 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 10-week window.
- Unit cost held within 1.5% of the original quotation.
- Inspection-related rejection stayed under 0.5%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.
