Tack Button for a Promotional Product Agency in Taiwan
A Promotional Product Agency approached us with a tack 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
- MOQ that was quoted per colourway rather than per style
- Shade drift between the approved lab dip and the bulk lot
- An interlining that bubbled after the first press
What we specified
| Item | Tack Button |
|---|---|
| Client type | A Promotional Product Agency |
| Market | Taiwan |
| Order volume | 20,000 pieces across 2 specifications |
| Base material | Glass |
| Standard size | 25 mm Width |
| Finish | Gunmetal Finish |
| Sampling rounds | 4 |
| Delivery window | 8 weeks from PO to ex-factory |
| Compliance | OEKO-TEX Standard 100 |
How it was resolved
- We rebuilt the specification around Glass and locked the tolerance before bulk.
- The finish was moved to Matte Black 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
- 20,000 pieces delivered inside the 8-week window.
- Unit cost held within 1.5% 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.
