Heat Transfer Label for a Uniform Supplier in Peru
A Uniform Supplier approached us with a heat transfer label requirement for the Peru 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
- Shade drift between the approved lab dip and the bulk lot
- Shrinkage that only showed up after the first wash
- A zipper puller that broke under pull test at the warehouse
What we specified
| Item | Heat Transfer Label |
|---|---|
| Client type | A Uniform Supplier |
| Market | Peru |
| Order volume | 2,000 pieces across 3 specifications |
| Base material | Glass |
| Standard size | 15 mm Width |
| Finish | Brushed Silver Finish |
| Sampling rounds | 2 |
| Delivery window | 6 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 Silicone 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
- 2,000 pieces delivered inside the 6-week window.
- Unit cost held within 4.5% 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
Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
