Satin Fabric for a Car Interior Supplier in Japan
A Car Interior Supplier approached us with a satin fabric 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
- A spec that lived in an email instead of a tech pack
- A zipper puller that broke under pull test at the warehouse
- Reorders that quietly changed supplier and changed the hand feel

What we specified
| Item | Satin Fabric |
|---|---|
| Client type | A Car Interior Supplier |
| Market | Japan |
| Order volume | 2,000 pieces across 3 specifications |
| Base material | Rubber |
| Standard size | 280 gsm |
| Finish | Rainbow Iridescent Finish |
| Sampling rounds | 4 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | RoHS |
How it was resolved
- We rebuilt the specification around Rubber and locked the tolerance before bulk.
- The finish was moved to Pearlescent 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
- 2,000 pieces delivered inside the 4-week window.
- Unit cost held within 2.0% of the original quotation.
- Inspection-related rejection stayed under 0.5%.
- 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.
