Waterproof Seam Seal Tape for a Uniform Supplier in the Netherlands
A Uniform Supplier approached us with a waterproof seam seal tape requirement for the the Netherlands 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
- A zipper puller that broke under pull test at the warehouse
- A compliance document that arrived after the goods were already shipped
What we specified
| Item | Waterproof Seam Seal Tape |
|---|---|
| Client type | A Uniform Supplier |
| Market | the Netherlands |
| Order volume | 50,000 pieces across 4 specifications |
| Base material | POM Plastic |
| Standard size | 8# Gauge |
| Finish | Antique Brass Plating |
| Sampling rounds | 4 |
| Delivery window | 6 weeks from PO to ex-factory |
| Compliance | ISO 14001 |
How it was resolved
- We rebuilt the specification around POM Plastic 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
- 50,000 pieces delivered inside the 6-week window.
- Unit cost held within 1.5% of the original quotation.
- Inspection-related rejection stayed under 2.0%.
- 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.
