Shock Cord for a Supermarket Own-Brand Team in Chile
A Supermarket Own-Brand Team approached us with a shock cord requirement for the Chile 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
- Lead time quoted without the plating or dyeing sub-process
- Elastic that lost recovery after three washes

What we specified
| Item | Shock Cord |
|---|---|
| Client type | A Supermarket Own-Brand Team |
| Market | Chile |
| Order volume | 20,000 pieces across 3 specifications |
| Base material | Neoprene |
| Standard size | 6 mm Width |
| Finish | Matte Black 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 Neoprene 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
- 20,000 pieces delivered inside the 4-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
Approve a pre-production sample made from the actual bulk base material. Substitute material behaves differently in finishing.
