Leather Cord for a Car Interior Supplier in South Korea
A Car Interior Supplier approached us with a leather cord 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
- Cartons packed to the factory ratio instead of the buyer's size ratio
- Shrinkage that only showed up after the first wash
- MOQ that was quoted per colourway rather than per style
What we specified
| Item | Leather Cord |
|---|---|
| Client type | A Car Interior Supplier |
| Market | South Korea |
| Order volume | 5,000 pieces across 2 specifications |
| Base material | Nylon |
| Standard size | 6 mm Width |
| Finish | Piece-Dyed Finish |
| Sampling rounds | 4 |
| Delivery window | 6 weeks from PO to ex-factory |
| Compliance | ISO 105 Colour Fastness |
How it was resolved
- We rebuilt the specification around Nylon and locked the tolerance before bulk.
- The finish was moved to Nickel-Free Electroplating 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
- 5,000 pieces delivered inside the 6-week window.
- Unit cost held within 1.5% 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
Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
