Rivet for a Baby Product Brand in Spain
A Baby Product Brand approached us with a rivet requirement for the Spain 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
- Reorders that quietly changed supplier and changed the hand feel
- Shade drift between the approved lab dip and the bulk lot
- A zipper puller that broke under pull test at the warehouse
What we specified
| Item | Rivet |
|---|---|
| Client type | A Baby Product Brand |
| Market | Spain |
| Order volume | 5,000 pieces across 3 specifications |
| Base material | ABS Resin |
| Standard size | 15 mm Width |
| Finish | Antique Copper Finish |
| Sampling rounds | 3 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | ISO 105 Colour Fastness |
How it was resolved
- We rebuilt the specification around ABS Resin and locked the tolerance before bulk.
- The finish was moved to Antique Copper 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 10-week window.
- Unit cost held within 1.5% 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
Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
