Wool Fabric for a Denim Manufacturer in Peru
A Denim Manufacturer approached us with a wool fabric 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
- A spec that lived in an email instead of a tech pack
- Shrinkage that only showed up after the first wash
- A trim that passed sampling but failed in-line because it was never cycle tested
What we specified
| Item | Wool Fabric |
|---|---|
| Client type | A Denim Manufacturer |
| Market | Peru |
| Order volume | 20,000 pieces across 2 specifications |
| Base material | Nylon |
| Standard size | 80 gsm |
| Finish | Chrome Plating |
| Sampling rounds | 2 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | CPSIA |
How it was resolved
- We rebuilt the specification around Nylon and locked the tolerance before bulk.
- The finish was moved to Soft-Touch Rubber 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 5-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
Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.
