Chain Trim for a Footwear Factory in Japan
A Footwear Factory approached us with a chain trim requirement for the Japan 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
- Cartons packed to the factory ratio instead of the buyer's size ratio
- Elastic that lost recovery after three washes
- An interlining that bubbled after the first press

What we specified
| Item | Chain Trim |
|---|---|
| Client type | A Footwear Factory |
| Market | Japan |
| Order volume | 50,000 pieces across 2 specifications |
| Base material | Polyester |
| Standard size | 3# Gauge |
| Finish | Gunmetal Finish |
| Sampling rounds | 3 |
| Delivery window | 6 weeks from PO to ex-factory |
| Compliance | AATCC Test Methods |
How it was resolved
- We rebuilt the specification around Polyester 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 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
Approve a pre-production sample made from the actual bulk base material. Substitute material behaves differently in finishing.
