Zipper Chain for a Pet Product Brand in Poland
A Pet Product Brand approached us with a zipper chain requirement for the Poland 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
- Reorders that quietly changed supplier and changed the hand feel
- Lead time quoted without the plating or dyeing sub-process
What we specified
| Item | Zipper Chain |
|---|---|
| Client type | A Pet Product Brand |
| Market | Poland |
| Order volume | 20,000 pieces across 6 specifications |
| Base material | Recycled PET |
| Standard size | 9 mm Width |
| Finish | Nickel-Free Electroplating |
| Sampling rounds | 2 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | ISO 105 Colour Fastness |
How it was resolved
- We rebuilt the specification around Recycled PET and locked the tolerance before bulk.
- The finish was moved to Yarn-Dyed Finish 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
- 20,000 pieces delivered inside the 5-week window.
- Unit cost held within 4.5% of the original quotation.
- Inspection-related rejection stayed under 1.0%.
- 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.
