Zipper Chain for a Logistics Company in Thailand
A Logistics Company approached us with a zipper chain requirement for the Thailand 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 compliance document that arrived after the goods were already shipped
- Elastic that lost recovery after three washes
- Shade drift between the approved lab dip and the bulk lot
What we specified
| Item | Zipper Chain |
|---|---|
| Client type | A Logistics Company |
| Market | Thailand |
| Order volume | 10,000 pieces across 4 specifications |
| Base material | Brass |
| Standard size | 32 mm Width |
| Finish | Chrome Plating |
| Sampling rounds | 3 |
| Delivery window | 6 weeks from PO to ex-factory |
| Compliance | BSCI |
How it was resolved
- We rebuilt the specification around Brass and locked the tolerance before bulk.
- The finish was moved to Antique Brass Plating 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 6-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
Approve a pre-production sample made from the actual bulk base material. Substitute material behaves differently in finishing.
