Waterproof Seam Seal Tape for an Independent Boutique in Singapore
An Independent Boutique approached us with a waterproof seam seal tape requirement for the Singapore 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
- Shade drift between the approved lab dip and the bulk lot
- A compliance document that arrived after the goods were already shipped
- Cartons packed to the factory ratio instead of the buyer's size ratio
What we specified
| Item | Waterproof Seam Seal Tape |
|---|---|
| Client type | An Independent Boutique |
| Market | Singapore |
| Order volume | 10,000 pieces across 3 specifications |
| Base material | Acrylic |
| Standard size | 15 mm Width |
| Finish | Antique Brass Plating |
| Sampling rounds | 2 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | Bluesign |
How it was resolved
- We rebuilt the specification around Acrylic and locked the tolerance before bulk.
- The finish was moved to Powder 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 4-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
Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
