Waterproof Seam Seal Tape Sourcing Program for Car Seat Cover Makers: Blouses
Waterproof Seam Seal Tape Programme for Car Seat Cover Makers: Blouses
This programme covers the full path from a waterproof seam seal tape requirement to a repeatable bulk supply for car seat cover makers. Instead of buying whatever a catalogue happens to stock, you specify the base material, the 38 mm Width, the finish and the packing, and we hold that specification so every reorder matches the last one. It is built around blouses, which is where most of the specification detail sits.
The most common failure in waterproof seam seal tape sourcing is not price — it is drift. A base material changes mill, the shade moves, a plating bath changes and the item quietly stops matching the approved sample. We prevent that with a written spec, an approved counter sample and a golden sample retained at the factory.

What the programme covers
- Specification build from your tech pack or a physical reference sample
- Base material and finish options with costed alternatives
- Sampling, testing and approval against EN 71-3
- Bulk production with in-line inspection and photo reporting
- Packing, documentation and shipment under the agreed Incoterm
Recommended specifications
- TPU — chosen when the item has to survive repeated laundering
- Polyester — best balance of cost, availability and test performance
- Copper — selected for colour depth and finish stability
- Brass — chosen when the item has to survive repeated laundering

FAQ
How long does sampling take?
10 working days for the first sample, with 5 days per revision round. Plated or dyed-to-match items add a few days.
What happens if a bulk lot fails inspection?
The lot is reworked or remade at our cost. Inspection reports are shared before the balance payment is due.
What is the minimum order quantity?
Standard MOQ is 3000 per style per colour. Mixed colourways can be combined on the same spec if the base material is identical.
Can you match a physical sample?
Yes. Send the reference and we reverse engineer the specification, then produce a counter sample for approval before any bulk commitment.
Send the reference sample or tech pack and we will come back with a costed specification, a sampling timetable and the compliance documents your market requires.
