Sew-On Button for a Hospital Procurement Team in Canada
A Hospital Procurement Team approached us with a sew-on button requirement for the Canada 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
- MOQ that was quoted per colourway rather than per style
- A compliance document that arrived after the goods were already shipped
- A zipper puller that broke under pull test at the warehouse

What we specified
| Item | Sew-On Button |
|---|---|
| Client type | A Hospital Procurement Team |
| Market | Canada |
| Order volume | 10,000 pieces across 3 specifications |
| Base material | POM Plastic |
| Standard size | 38 mm Width |
| Finish | Soft-Touch Rubber Coating |
| Sampling rounds | 3 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | AATCC Test Methods |
How it was resolved
- We rebuilt the specification around POM Plastic and locked the tolerance before bulk.
- The finish was moved to Glossy Enamel 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
- 10,000 pieces delivered inside the 5-week window.
- Unit cost held within 3.0% 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
Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
