Shock Cord for a Supermarket Own-Brand Team in Colombia
A Supermarket Own-Brand Team approached us with a shock cord requirement for the Colombia 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
- Cartons packed to the factory ratio instead of the buyer's size ratio
- Elastic that lost recovery after three washes
What we specified
| Item | Shock Cord |
|---|---|
| Client type | A Supermarket Own-Brand Team |
| Market | Colombia |
| Order volume | 50,000 pieces across 4 specifications |
| Base material | Acrylic |
| Standard size | 8# Gauge |
| Finish | Yarn-Dyed Finish |
| Sampling rounds | 2 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | GB 18401 |
How it was resolved
- We rebuilt the specification around Acrylic 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
- 50,000 pieces delivered inside the 5-week window.
- Unit cost held within 4.5% 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
Approve a pre-production sample made from the actual bulk base material. Substitute material behaves differently in finishing.
