Seven steps from enquiry to delivery, and the traps at each one.
China is the largest producer of electric heating alloys, and buying from there is routine — but the process has traps that cost money when they are missed.
Marketplaces and search results mix manufacturers with trading companies. Ask for the business licence, a factory video, and a video call walking through the production floor.
Pitfall: trading companies quoting manufacturer prices, then sourcing from whoever is cheapest this month.
Give the grade, or the service temperature, atmosphere and furnace type. State form, size, quantity, and any standard (ASTM, EN, GB).
Pitfall: "we need heating wire" — the supplier can only guess, and you get something that does not fit.
Ask for unit price, MOQ, lead time, payment terms, and whether freight and tax are included.
Pitfall: a price that excludes freight and tax can land 30% higher than it looked.
Check dimensions, cold resistance, and composition. Keep a retained sample.
Pitfall: the sample is hand-picked, the bulk is not. Retain the sample and compare.
Common terms: 30% deposit with 70% against the bill of lading copy. Letters of credit for larger orders.
Pitfall: full prepayment. The risk sits entirely with the buyer.
Ask for photos during production and an inspection before dispatch — your own or a third party.
Pitfall: no inspection means any problem is discovered after the container has sailed.
Sea freight for volume, air for urgency, courier for samples. Make sure the documents match the destination country's requirements.
Pitfall: incomplete documents mean the goods sit in port accruing storage charges.

"Stock" means different things. It can mean finished goods on the shelf, semi-finished material, raw billet, or nothing at all. Ask specifically: "for this grade and size, what is the earliest dispatch date?" — and get it in writing.
