About MPNBridge

A real person, a narrow service and a visible next step.

MPNBridge is being built as a small, accountable sourcing service—not as a catalogue, a virtual inventory warehouse or a fictional global team.

Who is responsible

I'm Jason Cheng, based in Shenzhen.

I handle the first RFQ review, requirement clarification, China-side supplier coordination and order follow-up. The purpose is simple: give an overseas buyer one accountable contact when an exact part number or small BOM needs work in China.

I do not claim manufacturer authorization, stock that I do not hold, testing facilities that I do not operate, or a quality conclusion that the available evidence cannot support. A quotation should make the source type, current checks, open questions and customer approvals visible.

Why exact MPNs and small BOMs?

These are requests where specification discipline and coordination can be more valuable than adding another catalogue. A missing suffix can change the part. Two prices are not comparable when their source, packing, date code, validity or trade terms differ. A ten-line BOM can also create ten separate follow-ups.

MPNBridge focuses on making those details easier to review and hand over. It is not intended to replace a direct authorized purchase when that is already the simplest and safest route.

Company and brand

MPNBridge is the English-facing brand of 深圳市源序科技有限公司, currently completing registration in Shenzhen.

The public location is currently limited to Shenzhen, China. Formal quotations, contracts, payment details and shipment documents must use the actual entity and terms confirmed for that transaction.

What you can expect

Small-company transparency.

One contact

The person who receives the RFQ remains visible through clarification and follow-up.

Written boundaries

Source status, checks, unavailable evidence and customer approvals are not hidden behind “quality guaranteed.”

Evidence before scale

Cases, response times, delivery countries and testimonials will be added only after they exist and can be disclosed.
