Sew-On Button for a Supermarket Own-Brand Team in Taiwan
A Supermarket Own-Brand Team approached us with a sew-on button requirement for the Taiwan 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
- Reorders that quietly changed supplier and changed the hand feel
- Shrinkage that only showed up after the first wash
- MOQ that was quoted per colourway rather than per style
What we specified
| Item | Sew-On Button |
|---|---|
| Client type | A Supermarket Own-Brand Team |
| Market | Taiwan |
| Order volume | 20,000 pieces across 2 specifications |
| Base material | Zinc Alloy |
| Standard size | 38 mm Width |
| Finish | Antique Copper Finish |
| Sampling rounds | 2 |
| Delivery window | 8 weeks from PO to ex-factory |
| Compliance | OEKO-TEX Standard 100 |
How it was resolved
- We rebuilt the specification around Zinc Alloy and locked the tolerance before bulk.
- The finish was moved to Enzyme Wash 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 8-week window.
- Unit cost held within 4.5% 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
Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.
