Q1: How fast can you deliver a custom matching transformer to the USA?
A: Standard stock ships within 3‑5 working days. Custom designs (prototype) are ready in 7‑10 days, with express freight delivering to any U.S. port within 48 hours.
Q2: Do you offer OEM/ODM services for low‑volume orders?
A: Yes. Our R&D team can handle orders as low as 500 pcs with full design support, tooling, and certification assistance.
Q3: What certifications are required for industrial procurement?
A: We provide CE, UL, FCC, RoHS, CB, and ISO 9001 documentation. Additional certifications (e.g., IECEx) are available on request.
Q4: What payment terms are accepted?
A: We accept T/T, L/C at sight, and PayPal for samples. For recurring contracts, net‑30 or net‑60 terms can be negotiated after the first successful shipment.
Q5: How do you ensure consistent quality across large batches?
A: Automated winding machines, in‑process laser inspection, and 100 % electrical testing (HI‑pot, insulation resistance, load test) guarantee batch‑to‑batch uniformity.
Q6: Can you handle cross‑border logistics and customs clearance?
A: Yes. Our logistics team prepares all required export paperwork (commercial invoice, packing list, ECCN, CO, certificate of origin) and works with your freight forwarder.
Q7: What after‑sales support is available?
A: 24 / 7 technical hotline, free replacement within 12 months for any manufacturing defect, and on‑site engineering assistance for large projects.
