Procurement FAQ
What is the minimum order quantity?
Standard catalog parts: 50–100 pieces per SKU. Custom-manufactured parts: typically 200+ pieces, though we accommodate smaller pilot runs for new product development.
How long is the production lead time?
Stock items ship within 3–5 business days. Custom orders require 15–30 days depending on complexity and finishing requirements.
Can you match an existing part from another supplier?
Yes. Send us a sample, technical drawing, or even a photograph with key dimensions. Our engineering team will reverse-engineer and quote within 48 hours.
What payment terms do you offer?
T/T (30% deposit, 70% before shipment) is standard. For established accounts, we offer flexible terms including L/C and open-account arrangements.
Do you provide quality documentation?
Every shipment includes a Certificate of Conformance. Full material test reports (MTR), pressure test records, and third-party inspection reports are available on request.
How do you handle defective parts?
We maintain a defect rate below 0.3% across all product lines. In the event of a confirmed quality issue, we offer free replacement or credit on your next order — no disputes, no delays.
