1. What is your minimum order quantity (MOQ)?

   MOQ differs based on wire type, specifications and production craft. Small trial orders are acceptable for standard items. Please send your detailed demands for targeted quotation.

2. Are free samples available for testing?

   Yes, we provide test samples for performance verification. Sample lead time is around 3–7 working days subject to specifications and stock status.

3. Can you customize wire parameters as our drawings?

   Fully customizable service is supported. We adjust conductor size, insulation grade, thermal class, surface color and packaging to fit your unique application demands.

4. Which international standards do your products follow?

   Our production complies with global mainstream standards including JIS, NEMA and IEC. Custom standard compliance can be realized for special industrial requirements.

5. How long is your regular production lead time?

   Lead time varies by item and order volume. Standard flat wires take 2–3 weeks after deposit confirmation; customized products need extra production cycle accordingly.
