Frequently Asked Questions

What Buyers Want to Know Before Ordering

Common questions from international OEM customers. Don't see your question? Just ask via the form above.

What is your minimum order quantity (MOQ)?

For most standard harness types, our MOQ is 500 pieces. For complex custom assemblies or specific automotive-grade requirements, MOQ may start at 1,000 pieces.

For prototyping and engineering samples, we accept orders as small as 5–20 pieces to support your validation phase. Sample tooling fees may apply for fully custom designs.

How fast can I receive a sample?

Once we receive your approved drawing and confirm specifications, sample lead time is typically 7–15 working days, depending on connector availability and assembly complexity.

If connectors need to be sourced from specific brands (TE, Molex, JST, Yazaki, Sumitomo), please indicate the part numbers in your inquiry so we can confirm stock and timing upfront.

What certifications do you hold?

Our quality management system is certified to IATF 16949 (automotive), and our facility is ISO 9001 compliant. Specific product lines carry UL component recognition and CCC certification.

All products meet RoHS and REACH requirements for European markets. Reach certificates and test reports are available upon request after RFQ approval.

Do you accept OEM and ODM projects?

Yes. We handle three engagement models:

β‘  Build-to-Print (OEM): You provide drawings and specifications, we manufacture exactly to spec.
β‘‘ Co-Design (ODM): You share the use case and performance requirements, our engineering team designs the harness, you approve.
β‘’ Reverse Engineering: You send a physical sample, we replicate or improve.

What payment terms do you offer?

For first-time orders, we typically require 30% T/T deposit upon order confirmation and 70% balance before shipment. For samples below $500, full prepayment is required.

For repeat customers and established business relationships, we can extend terms to L/C at sight, D/P, or Net 30/60 after credit review.

We accept payments in USD, EUR, RMB via T/T (wire transfer), L/C, Western Union, and PayPal (for samples only).

How do you handle shipping to my country?

We ship globally via DHL, FedEx, UPS (express, 3–7 days), air freight (5–10 days), and sea freight (25–40 days depending on destination).

Common Incoterms supported: EXW, FOB Shenzhen/Yantian, CIF, DAP, DDP. We can recommend the best option for your order size and destination.

Our team handles export documentation: commercial invoice, packing list, certificate of origin (Form A, FTA), test reports, and any country-specific compliance documents.

Can you sign an NDA before discussing my project?

Absolutely. We routinely sign Non-Disclosure Agreements before reviewing confidential drawings, especially for new product development, defense, medical, or proprietary EV/semiconductor applications.

Send us your standard NDA template, or request ours, and our legal team will execute it within 1–2 business days.

What languages does your sales team speak?

Our sales engineering team supports English and Mandarin Chinese fluently. For German, Spanish, French, Italian, Portuguese and other European languages, we have translation partners for technical documents and can respond via written communication.

WhatsApp and email are typically the most efficient channels for international communication across time zones.
