Grommet for a Car Interior Supplier in Singapore
A Car Interior Supplier approached us with a grommet requirement for the Singapore 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 trim that passed sampling but failed in-line because it was never cycle tested
- A spec that lived in an email instead of a tech pack
- A zipper puller that broke under pull test at the warehouse
What we specified
| Item | Grommet |
|---|---|
| Client type | A Car Interior Supplier |
| Market | Singapore |
| Order volume | 5,000 pieces across 3 specifications |
| Base material | PU Leather |
| Standard size | 50 mm Width |
| Finish | Yarn-Dyed Finish |
| Sampling rounds | 3 |
| Delivery window | 6 weeks from PO to ex-factory |
| Compliance | BSCI |
How it was resolved
- We rebuilt the specification around PU Leather and locked the tolerance before bulk.
- The finish was moved to Brushed Silver 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
- 5,000 pieces delivered inside the 6-week window.
- Unit cost held within 2.0% 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
Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
