Woven Interlining for a Supermarket Own-Brand Team in the United States
A Supermarket Own-Brand Team approached us with a woven interlining requirement for the the United States 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 zipper puller that broke under pull test at the warehouse
- A compliance document that arrived after the goods were already shipped

What we specified
| Item | Woven Interlining |
|---|---|
| Client type | A Supermarket Own-Brand Team |
| Market | the United States |
| Order volume | 5,000 pieces across 2 specifications |
| Base material | Recycled PET |
| Standard size | 3# Gauge |
| Finish | Matte Black Coating |
| 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 Recycled PET and locked the tolerance before bulk.
- The finish was moved to Matte Black Coating 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 1.0%.
- 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.
