Sourcing interactive flat panels — smart boards — from China can cut your hardware cost dramatically, but the difference between a good factory and a problematic one only shows up after you have wired the deposit. This checklist is the same one we recommend to our own OEM/ODM partners before they sign with any supplier, including us.
1. Verify the factory, not just the website
Ask for a live video factory tour, a business license, and the factory address — then check that address on a map. A real manufacturer will happily show assembly lines, aging-test racks and warehouse stock on a video call. If you can, commission a third-party audit (SGS, TÜV, BV); it costs a few hundred dollars and pays for itself the first time it filters out a trading company posing as a factory.
2. Check certifications match your target market
For North America, the baseline is FCC (EMC compliance). For Europe, CE and RoHS. CB scheme certificates simplify multi-country safety approval, and ISO 9001 tells you the factory runs a documented quality system. If you need Google Mobile Services on a smart board, ask specifically about Google EDLA certification — it is not the same as "runs Android". Always request the actual certificate files and verify the certificate holder matches the factory name.
3. Test the sample policy before discussing price
A supplier confident in its product makes sampling easy. Typical industry practice: standard samples ship within 7–15 working days, and the sample fee is refundable or deductible against your first volume order. If a supplier refuses samples, or will only sell a full container first, walk away. When the sample arrives, test touch accuracy, boot time, Wi-Fi stability and the actual firmware build — not just the spec sheet.
4. Understand the real MOQ
Minimum order quantity decides whether you can test a market before committing. Some factories demand 100+ units for any customization; others — including our OEM/ODM program — start custom orders (logo, firmware, packaging) from as few as 5 units. Ask for the MOQ at three levels: standard model, logo customization, and full ODM. Also ask how pricing scales, because a factory that welcomes small trial orders usually grows with you instead of forcing a large first commitment.
5. Read the warranty and spare-parts terms line by line
"One year warranty" means little without detail. Ask: Is the warranty whole-unit or parts-only? Who pays shipping on warranty claims? How long are spare parts — mainboards, panels, power boards — guaranteed to remain available? A strong benchmark in this industry is a 2-year whole-unit warranty with spare parts available for 10 years. Get the RMA process in writing, including response times and how DOA (dead-on-arrival) units are handled.
6. Score their customization capability
For traders and brands, the supplier's engineering depth matters more than the unit price. Can they modify the bezel, boot logo, launcher UI and pre-installed apps? Do they offer OPS slot configurations, camera/mic options, and custom packaging? Can they supply SKD/CKD kits if you later assemble locally? Ask for photos of previous white-label projects — a capable OEM partner will have a portfolio of brands they have built for.
7. Judge communication before you need it
Time-zone overlap, response speed and documentation quality predict how problems will be handled later. Send a technical question and a documentation request (spec sheet, mechanical drawing, certificate copies) and see what comes back. Suppliers who support project tenders with drawings, SDK access and compliance packs tend to be organized everywhere else too.
The bottom line
Price is the last thing to negotiate, not the first. A supplier that passes all seven checks — verified factory, market-matched certifications, easy sampling, flexible MOQ, a real warranty, deep customization and responsive communication — will almost always cost you less over a three-year relationship than the cheapest quote on the table.
