Metallic Thread for a Bag and Luggage Maker in Hong Kong
A Bag and Luggage Maker approached us with a metallic thread 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
- Cartons packed to the factory ratio instead of the buyer's size ratio
- Reorders that quietly changed supplier and changed the hand feel
- MOQ that was quoted per colourway rather than per style

What we specified
| Item | Metallic Thread |
|---|---|
| Client type | A Bag and Luggage Maker |
| Market | Hong Kong |
| Order volume | 2,000 pieces across 4 specifications |
| Base material | Zinc Alloy |
| Standard size | 9 mm Width |
| Finish | Glossy Enamel Coating |
| Sampling rounds | 4 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | EN 71-3 |
How it was resolved
- We rebuilt the specification around Zinc Alloy and locked the tolerance before bulk.
- The finish was moved to Yarn-Dyed 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
- 2,000 pieces delivered inside the 4-week window.
- Unit cost held within 3.0% of the original quotation.
- Inspection-related rejection stayed under 0.5%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
