Cotton Thread with Yarn-Dyed Finish for Underwear
This cotton 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 yarn-dyed finish surface, the 25 mm Width 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 shade drift between the approved lab dip and the bulk lot, or a trim that passed sampling but failed in-line because it was never cycle tested. 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.
How long does sampling take?
10 working days for the first sample, with 3 days per revision round. Plated or dyed-to-match items add a few days.
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.
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.
