Stud Trim for a School Uniform Buyer in Mexico
A School Uniform Buyer approached us with a stud trim requirement for the Mexico 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
- An interlining that bubbled after the first press
- Elastic that lost recovery after three washes
- Lead time quoted without the plating or dyeing sub-process
What we specified
| Item | Stud Trim |
|---|---|
| Client type | A School Uniform Buyer |
| Market | Mexico |
| Order volume | 5,000 pieces across 2 specifications |
| Base material | Genuine Leather |
| Standard size | 9 mm Width |
| Finish | Powder Coating |
| Sampling rounds | 4 |
| Delivery window | 8 weeks from PO to ex-factory |
| Compliance | EN 71-3 |
How it was resolved
- We rebuilt the specification around Genuine Leather and locked the tolerance before bulk.
- The finish was moved to Piece-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
- 5,000 pieces delivered inside the 8-week window.
- Unit cost held within 2.0% 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
Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.
