How to verify a Chinese factory without flying there
Updated September 2026 · 7 min read
Most bad sourcing outcomes are not caused by bad factories — they are caused by unverified assumptions. The factory you found on a listing site may be real, may be a middleman with a showroom, or may not exist as described. Here is the verification sequence we run for every new supplier, and what you should demand from anyone who claims to check for you.
Step 1 — Paper trail (do this today, costs nothing)
- Business license. Ask for the license scan and check the registered capital, scope and establishment date. A "manufacturer" registered last year with tiny capital is a red flag.
- Public credit record. China's public enterprise credit systems show lawsuits, default lists and administrative penalties. Get a screenshot, not a verbal assurance.
- Export track record. Ask which ports they ship from and request one (redacted) bill of lading copy. No export history means longer learning curves — and hidden forwarding costs.
Step 2 — Live video walkthrough (not a showroom tour)
A real visit answers three questions: do the machines for your product exist, are they running, and does the place match the photos? Insist on a live call where you direct the camera: walk from the gate, show the workshop floor, film machines actually running your type of product, and pan across the warehouse. Recorded showroom reels prove nothing.
Step 3 — Sample teardown, not just a sample
A beautiful golden sample is often hand-finished by the boss's best worker. What matters is what mass production will look like. Before the sample ships to you, have someone on-site: weigh and measure it against spec, open it up, check material claims, and photograph everything with dates. Demand a written report with measurements — not three photos on WeChat.
Step 4 — Pre-shipment inspection with teeth
Before the balance payment, run an AQL 2.5/4.0 inspection: correct quantity, workmanship sampling, function tests, barcode and artwork verification, carton drop tests. The report should end with a PASS / FAIL / PENDING verdict and photo evidence — and your payment terms should be tied to it.
The documents to demand from any agent
- License copy + public-record screenshot (dated)
- Dated on-site photos and video walkthrough
- Sample inspection report with measurements
- Container and seal numbers with loading photos
This is exactly the evidence pack we deliver with every order. You should not fly 9,000 km to find out what a camera and a checklist would have told you for free. See our sample inspection report or send us a product to verify.
