Zipper Tape for a Craft Wholesaler in Spain
A Craft Wholesaler approached us with a zipper tape 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
- A spec that lived in an email instead of a tech pack
- Reorders that quietly changed supplier and changed the hand feel
- Lead time quoted without the plating or dyeing sub-process
What we specified
| Item | Zipper Tape |
|---|---|
| Client type | A Craft Wholesaler |
| Market | Spain |
| Order volume | 5,000 pieces across 2 specifications |
| Base material | ABS Resin |
| Standard size | 50 mm Width |
| Finish | Soft-Touch Rubber Coating |
| Sampling rounds | 3 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | Bluesign |
How it was resolved
- We rebuilt the specification around ABS Resin and locked the tolerance before bulk.
- The finish was moved to Mercerised 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 4.5% of the original quotation.
- Inspection-related rejection stayed under 1.5%.
- 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.

Tell us the item, the quantity and the delivery window. We will quote it with the sub-processes named, so the lead time you approve is the lead time you get.
