1. Verify certifications — and check the listing number yourself
For the US and Canada, check both plumbing and electrical evidence for the exact model. Do not accept a logo alone: ask for the listing number and covered-model scope. WaterSense and ADA are separate program or project requirements and must also be checked per model.
- ✓cUPC (IAPMO R&T) — ask for the File Number and verify at pld.iapmo.org
- ✓ETL (US) — electrical safety listing
- ✓WaterSense (EPA) — water-efficiency labeling
- ✓ADA — compliant seat heights for commercial/accessibility projects
- ✓EU buyers: confirm CE; UK buyers: confirm UKCA and WRAS requirements per order
2. Confirm OEM / ODM and private-label scope
A real manufacturer (not a trading company) should brand the product as yours end-to-end. Clarify exactly what is customizable and what the tooling/branding minimums are.
- ✓Your logo on unit, remote, packaging, manual and barcodes
- ✓Custom remote / app, color and finish options
- ✓Written MOQ per model, packaging and customization level
- ✓Whether they own the factory (ask for it — trading companies add cost and risk)
3. Pin down commercial terms — MOQ, pricing, lead time, samples
Get these in writing before you compare quotes. Do not infer price, MOQ, lead time, stock or sample availability from general marketing copy.
- ✓MOQ per model and for a mixed container
- ✓FOB / CIF / DDP pricing to your port
- ✓Production and approval lead time for the exact order
- ✓Sample availability, cost and delivery timing
4. Match the specifications to your market
Smart toilets are electro-mechanical products — the spec sheet matters. Confirm dimensions and rough-in fit your market’s plumbing, and that heating, drainage and voltage are right.
- ✓Tankless instant heating vs tank — instant heating gives unlimited warm water
- ✓Dimensions (W×D×H) and rough-in distance (e.g. 300/400 mm)
- ✓Floor vs wall drainage to match the installation
- ✓Voltage configured for the destination market
- ✓Core features: heated seat, warm-water wash, warm-air drying, self-cleaning nozzle, auto open/close
5. Do basic factory due diligence
Reduce risk before you wire a deposit. Reputable factories are transparent about capacity, testing and references.
- ✓Production capacity evidence and agreed inspection plan
- ✓Verifiable certifications (see step 1) and export references
- ✓Responsiveness — a supplier slow to reply pre-sale is slower post-sale
- ✓Clear warranty and spare-parts support

A worked example: applying the checklist to OTOL
OTOL supplies integrated smart toilets and bidet seats for OEM/ODM and private-label programs. North American buyers can request current cUPC and ETL evidence, ask for the current file number and match the quoted variant in the IAPMO R&T directory — while WaterSense, ADA, MOQ, pricing, stock, lead time and samples are confirmed separately for the exact order.
Frequently asked questions
How do I verify a Chinese smart toilet manufacturer’s cUPC certification?
Ask for the current IAPMO R&T file number, validity and covered-model list, then look it up in the public directory and match the exact quoted model.
What MOQ should I expect from a smart toilet OEM factory?
There is no reliable universal MOQ. It depends on model, voltage, tooling, packaging and customization, so compare written quotations on the same scope.
What certifications do I need to import smart toilets into the US?
Check plumbing and electrical requirements such as cUPC and ETL for the exact model. WaterSense and ADA are separate requirements that may apply depending on the product and project; do not assume they cover every model.
Is instant (tankless) heating better than a tank model?
Tankless instant heating provides continuous warm water without waiting for a reservoir to reheat, which is preferred in most markets. Confirm the heating method on the spec sheet for each model.
Should I buy from a manufacturer or a trading company?
Buying direct from the manufacturer usually means better pricing, faster technical support, genuine OEM/private-label capability, and clearer certification ownership. Ask whether the supplier owns the factory.
