For standard items, we offer flexible MOQs, typically starting at 500-1000 pieces per item to make trial orders accessible. For custom ODM projects, the MOQ is based on the tooling and production setup, which we will discuss transparently.
Absolutely. Customization is our strength. Send us your drawings or samples, and our engineering team will provide a feasibility analysis, a quote, and produce prototypes for your approval before mass production.
We provide FOB (Free On Board) prices from our nearest port (Tianjin/Xingang) for most orders. This gives you control over your choice of freight forwarder and final shipping costs. For larger projects, CIF quotes are available upon request.
Quality control is integrated at three stages: 1) Incoming Material Check, 2) In-Process Inspection during stamping, forming, and welding, and 3) Final Pre-shipment Inspection for dimensions, finish, and packaging. We can arrange third-party inspections (e.g., SGS) if required.
Standard terms are 30% deposit via T/T, 70% balance against copy of Bill of Lading. For established clients, other terms can be discussed. We use secure, standard international banking procedures.
Yes, we provide free samples of our standard products. You only need to cover the freight cost. For custom-designed samples, a modest tooling/sample fee may apply, which is often credited against your first bulk order.
"I was hesitant to source directly from China, but Jinzehong's communication was flawless—in perfect English. The duct connectors were packaged perfectly, no damage, and exactly to the spec sheet. We've locked in an annual contract."
"Their quality is on par with European suppliers we've used, but the pricing is significantly more competitive. The CE documentation they provided for our project was complete and accurate, making our compliance review easy."
"We had a rush project with a non-standard rectangular-to-round transition. Not only did Jinzehong deliver the custom connectors within 3 weeks, but their technical drawing before production caught a minor flaw in our own spec. Saved us time and money."
