Overlocking Thread Sourcing Program for Airlines and Rail Operators: Underwear
Overlocking Thread Programme for Airlines and Rail Operators: Underwear
This programme covers the full path from a overlocking thread requirement to a repeatable bulk supply for airlines and rail operators. Instead of buying whatever a catalogue happens to stock, you specify the base material, the 50 mm Width, the finish and the packing, and we hold that specification so every reorder matches the last one. It is built around underwear, which is where most of the specification detail sits.
The most common failure in overlocking thread 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 REACH SVHC Screening
- Bulk production with in-line inspection and photo reporting
- Packing, documentation and shipment under the agreed Incoterm
Recommended specifications
- POM Plastic — best balance of cost, availability and test performance
- Rubber — best balance of cost, availability and test performance
- Recycled PET — chosen when the item has to survive repeated laundering
- Wood — best balance of cost, availability and test performance

FAQ
How long does sampling take?
14 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.
Which compliance documents do you provide?
REACH SVHC Screening documentation is issued with the shipment. Test reports can be ordered against any additional standard you nominate.
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.
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.
