Sewing Thread with Piece-Dyed Finish for Underwear
This sewing thread is supplied to a written specification so that reorders match the approved sample. The product spec is fixed at quotation stage — base material, the piece-dyed finish surface, the 8# Gauge and the packing — and held on file, which is what keeps underwear consistent across seasons instead of drifting with whatever the mill happens to have in stock.
The usual reason buyers come to us is not price. It is a compliance document that arrived after the goods were already shipped, or reorders that quietly changed supplier and changed the hand feel. Both are preventable once the specification is written down before bulk starts.

FAQ
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.
What are the payment and delivery terms?
Standard terms are a deposit with the order and the balance before shipment, under EXW / FOB / CIF / DDP as agreed.
How long does sampling take?
7 working days for the first sample, with 5 days per revision round. Plated or dyed-to-match items add a few days.
Which compliance documents do you provide?
Sedex SMETA documentation is issued with the shipment. Test reports can be ordered against any additional standard you nominate.
