ABOUT

Run by hardware engineers, for hardware buyers.

Most sourcing agents are logistics coordinators who happen to be in China. We're engineers who happen to do sourcing. That's a different product.

Our Story

I'm Martin, founder of Sky Flux — the company behind China Sourcing Agents. Before this, I spent 7 years as a hardware and full-stack engineer — building port management systems, IoT sensor networks, and embedded devices for clients across Asia.

During that time, I watched procurement team after procurement team get burned by sourcing agents who couldn't read a schematic, didn't know what a BOM was, and couldn't tell a factory from a trader. The result: wrong components, failed certifications, production runs that had to be scrapped.

I started China Sourcing Agents to fix that. Not with a team of salespeople, but with a founder who actually knows the difference between a LoRa module and a LoRa gateway, and why that matters when you're placing a $40,000 order.

How We Work

Transparent pricing
You see the factory quote. Our fee is on top, stated clearly. No rebates, no hidden margins.
Direct factory contact
After the first order, you have direct factory contact. We don't create dependency — we create relationships.
Weekly status reports
Every active production order gets a written status update every Friday, with photos from any inspections that week.
Technical English
We handle all factory communication. If there's a technical issue, we translate it accurately — not approximately.

I'm Martin Wang, founder of Sky Flux and the sourcing engineer behind every project on this site. Before starting China Sourcing Agents, I spent 7+ years as a hardware and full-stack engineer — building port-management systems, LoRa sensor networks, and embedded devices for clients across Asia.

That background matters because electronics sourcing is not a messaging problem. A factory can say "yes" to a spec they don't actually understand. I review schematics, evaluate BOMs, check PCB stack-ups for manufacturability, and assess FCC/CE/UKCA/PSE compliance risk before you commit tooling budget.

Hardware + full-stack engineer
7+ years building firmware, embedded devices, and production systems — not just forwarding emails.
Reads schematics and BOMs
We catch DFM issues, component substitutions, and bad PCB stack-ups before tooling is cut.
Certification risk assessment
FCC, CE, UKCA, PSE, UN 38.3, IEC — flagged during scoping, not after your shipment hits customs.
On-site in China
Room 3014, Tower 3, Excellence Century Center, Fuhua 3rd Road, Futian District, Shenzhen, 518048, Guangdong, China. Travels to factory floors in Shenzhen, Dongguan, and Yiwu for audits and inspections.

Why us

5–8%
Commission

Stated separately from the factory quote. No hidden margin. Factory audits run $300–800.

15–20
Active clients

We cap our roster so your project gets a real engineer, not a ticket queue.

< 1%
Average defect rate

Three-stage QC (pre-production, in-line, pre-shipment) catches drift before it becomes scrap.

24 hrs
Response SLA

Reply within 24 hours, including weekends. Weekly status reports with factory photos.

How we work

Every engagement follows the same 10-step process — from RFQ and technical scoping through factory search, on-site audit, sample approval, three-stage QC, and door-to-door logistics. You are actively involved in steps 1–3; after that, we handle the factory work and ask for about 1–2 hours of your time per week to review reports and approve decisions.

Our Values

Engineering rigor over sales talk

We'll tell you if your design has a DFM problem before we find you a factory. That's more useful than just taking your order.

Long-term over single deals

The goal is a factory relationship that works for your 10th order, not just your first. We optimize for that from day one.

Transparent over comfortable

If an inspection finds problems, we send you the photos and the honest assessment — not a softened version designed to avoid conflict.

Trust signals

Transparent pricing
You see the factory quote and our fee separately. Commission is 5–8% of order value; standalone audits are $300–800.
No factory rebates
We do not take kickbacks or hidden incentives from factories. Our only income is the fee you approve in writing.
Direct factory contact
After the first order, you get the factory contact. We build relationships, not dependency.
Weekly reports
Every active order gets a written Friday update with inspection photos, audit findings, and clear next steps.
No hidden margin
The factory price is the factory price. We do not mark up quotes or add undisclosed spreads.
On-site verification
We visit factories in person — no virtual tours, no third-party subcontractors without your knowledge.
