Seat Belt Webbing for a Bridal Studio in South Korea
A Bridal Studio approached us with a seat belt webbing requirement for the South Korea 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
- MOQ that was quoted per colourway rather than per style
- Elastic that lost recovery after three washes
What we specified
| Item | Seat Belt Webbing |
|---|---|
| Client type | A Bridal Studio |
| Market | South Korea |
| Order volume | 20,000 pieces across 2 specifications |
| Base material | ABS Resin |
| Standard size | 3# Gauge |
| Finish | Pearlescent Coating |
| Sampling rounds | 4 |
| Delivery window | 8 weeks from PO to ex-factory |
| Compliance | BSCI |
How it was resolved
- We rebuilt the specification around ABS Resin and locked the tolerance before bulk.
- The finish was moved to Yarn-Dyed 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
- 20,000 pieces delivered inside the 8-week window.
- Unit cost held within 3.0% 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
Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.
