Two-Way Separating Zipper for a Hospital Procurement Team in Vietnam
A Hospital Procurement Team approached us with a two-way separating zipper requirement for the Vietnam 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
- Shade drift between the approved lab dip and the bulk lot
- MOQ that was quoted per colourway rather than per style
- Lead time quoted without the plating or dyeing sub-process
What we specified
| Item | Two-Way Separating Zipper |
|---|---|
| Client type | A Hospital Procurement Team |
| Market | Vietnam |
| Order volume | 20,000 pieces across 4 specifications |
| Base material | Cotton |
| Standard size | 38 mm Width |
| Finish | Rainbow Iridescent Finish |
| Sampling rounds | 3 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | REACH SVHC Screening |
How it was resolved
- We rebuilt the specification around Cotton and locked the tolerance before bulk.
- The finish was moved to Nickel-Free Electroplating 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 4.5% 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.
