Carabiner Clip for a Denim Manufacturer in Ireland
A Denim Manufacturer approached us with a carabiner clip requirement for the Ireland 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
- Shrinkage that only showed up after the first wash
- A spec that lived in an email instead of a tech pack
- An interlining that bubbled after the first press
What we specified
| Item | Carabiner Clip |
|---|---|
| Client type | A Denim Manufacturer |
| Market | Ireland |
| Order volume | 20,000 pieces across 3 specifications |
| Base material | TPU |
| Standard size | 9 mm Width |
| Finish | Soft-Touch Rubber Coating |
| Sampling rounds | 3 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | California Prop 65 |
How it was resolved
- We rebuilt the specification around TPU and locked the tolerance before bulk.
- The finish was moved to Anodised 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 4-week window.
- Unit cost held within 3.0% of the original quotation.
- Inspection-related rejection stayed under 2.0%.
- 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.
