RFQ FAQ

What should I include in the RFQ?
Send drawings or sample photos, material, size, quantity, finish, application and inspection requirements.

Can XiYu quote from samples?
Yes. Photos and measurements help initial review; physical samples can be used for confirmation when needed.

Is pricing fixed online?
