Heat Transfer Vinyl for a Footwear Factory in Vietnam
A Footwear Factory approached us with a heat transfer vinyl 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
- A spec that lived in an email instead of a tech pack
- An interlining that bubbled after the first press
- Reorders that quietly changed supplier and changed the hand feel

What we specified
| Item | Heat Transfer Vinyl |
|---|---|
| Client type | A Footwear Factory |
| Market | Vietnam |
| Order volume | 10,000 pieces across 2 specifications |
| Base material | POM Plastic |
| Standard size | 38 mm Width |
| Finish | Black Nickel Finish |
| Sampling rounds | 4 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | ISO 9001 |
How it was resolved
- We rebuilt the specification around POM Plastic and locked the tolerance before bulk.
- The finish was moved to UV Printing 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 1.5% 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
Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.
