FAQ
1. What's the minimum quantity customer can order?
If we have your size in stock, we can provide any quantity you
want.
If we do not have, for spool wire, we can produce 1 spool, about
2-3kg. For coil wire, 25kg.
2. How can you pay for small sample amount?
We have account, wire transfer for sample amount also ok.
3. Customer do not have express account. How will us arrange the
delivery for sample order?
Just need to provide your address information, we will check the
express cost, you can arrange the express cost together with sample
value.
4. What's our payment terms?
We can accept LC T/T payment terms, it also depending on delivery
and total amount. Let's talk more in details after getting your
detailed requirements.
5. Do you provide free samples?
If you want several meters and we have stock of your size, we can
provide, customer need to bear the International express cost.
