Eyelet for a Car Interior Supplier in Poland
A Car Interior Supplier approached us with a eyelet 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
- A zipper puller that broke under pull test at the warehouse
- Shrinkage that only showed up after the first wash
- Lead time quoted without the plating or dyeing sub-process

What we specified
| Item | Eyelet |
|---|---|
| Client type | A Car Interior Supplier |
| Market | Poland |
| Order volume | 10,000 pieces across 4 specifications |
| Base material | PU Leather |
| Standard size | 38 mm Width |
| Finish | Glossy Enamel Coating |
| Sampling rounds | 4 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | EN 71-3 |
How it was resolved
- We rebuilt the specification around PU Leather and locked the tolerance before bulk.
- The finish was moved to Antique Copper 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
- 10,000 pieces delivered inside the 4-week window.
- Unit cost held within 4.5% of the original quotation.
- Inspection-related rejection stayed under 2.0%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
