Iron-On Patch for a Denim Manufacturer in New Zealand
A Denim Manufacturer approached us with a iron-on patch requirement for the New Zealand 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
- Elastic that lost recovery after three washes
- A compliance document that arrived after the goods were already shipped
- MOQ that was quoted per colourway rather than per style
What we specified
| Item | Iron-On Patch |
|---|---|
| Client type | A Denim Manufacturer |
| Market | New Zealand |
| Order volume | 5,000 pieces across 4 specifications |
| Base material | Ceramic |
| Standard size | 15 mm Width |
| Finish | Antique Brass Plating |
| Sampling rounds | 4 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | ISO 105 Colour Fastness |
How it was resolved
- We rebuilt the specification around Ceramic and locked the tolerance before bulk.
- The finish was moved to Mercerised 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 10-week window.
- Unit cost held within 2.0% 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.
