How to Verify a Chinese Sign Factory Before You Send a Deposit
Key takeaways
- Ask for a live video walkthrough of the workshop, not a photo gallery.
- Match the business licence, the factory address and the invoice beneficiary name.
- Pin the component brands in writing, then compare the part numbers on the goods.
- Pay against milestones you can verify: approved drawings, production photos, lighting test video.
Buying signage from overseas is routine once the supplier is real, and expensive when they are not. This checklist is the one we would use ourselves: it takes about a week, costs nothing, and filters out most trading companies pretending to be a factory.

Five checks that take a week
- A live video walkthrough — ask them to open a crate, show the welding bench and walk past finished goods with today's date visible
- The business licence, matched against the invoice beneficiary and the bank account name
- The factory address, checked on a map and against any verified supplier listing
- Component brands in writing: module brand and driver brand, with the part numbers you will find on the goods
- Two references from customers in your own market buying a similar product
Documents a real factory provides without arguing
- A quotation with the build written out: return material, face thickness, LED brand, driver brand, IP rating
- Drawings for approval before production, with dimensions and mounting points
- Component certification — CE, RoHS, EMC and UL listed options on request
- Photos or videos of the finished sign before packing, plus the lighting test result
- Packing list, crate dimensions and weight before the freight booking
- Warranty in writing: ours is 3 years on LED components and 5 years on the structural aluminium housing
Payment terms that protect both sides
- Deposit against the approved drawing, not against a verbal description
- Balance against photo or video approval of the finished sign, before the crate leaves
- Payment to the company named on the quotation and the business licence, never to an unrelated account
- On repeat orders, agree a spare-parts allowance: a driver and a handful of modules per build
We are happy to do the walkthrough and send component part numbers before any payment. If a supplier resists those two requests, that is the answer to the question you were asking.
Warning signs worth acting on
- A price far below the others with the specification left vague
- No drawing stage — production starting straight from a photo
- A bank account in a different company name, or a late change of beneficiary
- Unable to name the LED module or driver they use
- Pressure to pay in full before any production photo exists
Conclusion
Verification is not distrust; it is how trade buyers normally work. Ask for the walkthrough, match the documents, pin the components in writing, and pay against milestones you can see. Everything on the list is ordinary practice for a factory that intends to keep the account.
Frequently asked questions
How can I tell a factory from a trading company?
Ask for a live walkthrough showing production equipment and work in progress, then match the business licence, the factory address and the invoice beneficiary. Trading companies can quote well but usually cannot show you the line that will make your sign.
What certifications should a sign factory provide?
CE, RoHS and EMC are standard on our electrical components, with UL listed options for North American projects. Ask for component certificates rather than a company-level certificate, because it is the components that carry the listing.
Should I pay a deposit before seeing drawings?
No. The drawing is the specification, so pay the deposit once you have approved it. A supplier who cannot produce a drawing before payment has no record to manufacture against.
