Elastic Thread for a Workwear Distributor in South Africa
A Workwear Distributor approached us with a elastic thread requirement for the South Africa 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
- MOQ that was quoted per colourway rather than per style
- Shrinkage that only showed up after the first wash
- A zipper puller that broke under pull test at the warehouse

What we specified
| Item | Elastic Thread |
|---|---|
| Client type | A Workwear Distributor |
| Market | South Africa |
| Order volume | 50,000 pieces across 4 specifications |
| Base material | PU Leather |
| Standard size | 50 mm Width |
| Finish | Rose Gold Plating |
| Sampling rounds | 4 |
| Delivery window | 6 weeks from PO to ex-factory |
| Compliance | ISO 9001 |
How it was resolved
- We rebuilt the specification around PU Leather and locked the tolerance before bulk.
- The finish was moved to Anodised 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
- 50,000 pieces delivered inside the 6-week window.
- Unit cost held within 2.0% of the original quotation.
- Inspection-related rejection stayed under 2.0%.
- 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.
