Zipper Slider for a Baby Product Brand in Hong Kong
A Baby Product Brand approached us with a zipper slider requirement for the Hong Kong 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 compliance document that arrived after the goods were already shipped
- A zipper puller that broke under pull test at the warehouse
- Cartons packed to the factory ratio instead of the buyer's size ratio
What we specified
| Item | Zipper Slider |
|---|---|
| Client type | A Baby Product Brand |
| Market | Hong Kong |
| Order volume | 5,000 pieces across 2 specifications |
| Base material | POM Plastic |
| Standard size | 38 mm Width |
| Finish | Pearlescent Coating |
| Sampling rounds | 2 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | Bluesign |
How it was resolved
- We rebuilt the specification around POM Plastic and locked the tolerance before bulk.
- The finish was moved to Brushed Silver 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 2.0% 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
Approve a pre-production sample made from the actual bulk base material. Substitute material behaves differently in finishing.
