Silicone Patch for a Startup Apparel Label in Portugal
A Startup Apparel Label approached us with a silicone patch requirement for the Portugal 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
- Shrinkage that only showed up after the first wash
- MOQ that was quoted per colourway rather than per style
What we specified
| Item | Silicone Patch |
|---|---|
| Client type | A Startup Apparel Label |
| Market | Portugal |
| Order volume | 5,000 pieces across 6 specifications |
| Base material | Iron |
| Standard size | 10# Gauge |
| Finish | Powder Coating |
| Sampling rounds | 4 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | RoHS |
How it was resolved
- We rebuilt the specification around Iron 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
- 5,000 pieces delivered inside the 10-week window.
- Unit cost held within 1.5% 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
Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
