Heated massagers, NIR therapy devices and wearable heat products live on the boundary between electronics and personal care. That is exactly where sourcing mistakes are expensive. This checklist is what we walk our own buyers through before the first purchase order.
Request a scheduled live video walk-through. Check that the business licence name matches the name on your proforma invoice, and ask for a recent third-party audit (SGS, TÜV, BSCI). A real manufacturer shows lines without rehearsal time.
Certificates are issued per model and per market. Ask which certificate covers the exact SKU you are buying, who the certificate holder is, and whether it is still valid. A certificate held by a sister company does not cover your product.
For heated products: measure heat-up time, surface temperature uniformity across the pad, and stability over a full battery cycle. For air-pressure massagers: run the pump for its full rated cycle and check noise. Keep one sample as the reference for incoming QC.
"We can do 10,000 a month" means little. Ask which plant, how many lines, and what the daily output of that plant is. Honest suppliers state scope: for example, LightBDB's 5,000+ pcs/day figure refers to the Yangon plant only.
MOQ from 500 pcs per model is typical for body-care platforms (heated, NIR and wearable heat-therapy devices). Clarify whether tooling or moulds are needed, who owns them, and how sample fees are handled on a first order.
Default is usually FOB Shenzhen. Confirm the Incoterm, the port, freight method and payment structure (commonly T/T 30/70) before the proforma invoice is issued.
Agree the AQL level, who pays for pre-shipment inspection, and what happens on failure. Put it in the contract, not in a chat message.
The seven steps above decide who you buy from. They do not decide whether a specific container is allowed to leave. That is a separate set of judgements, and we publish ours so they can be checked rather than trusted.
Ask for the inspection standard by document number and revision. "We check it visually" is not a basis — it is one person's opinion on one day. If the report cannot cite a revision, the report proves nothing.
Invoice, packing list and carton marks must agree on both quantity and lot number. Two cartons of difference is not a rounding error; it means nobody cross-checked before the container was sealed.
The person who judges a release and the person who reviews it should be different people. A single signature means the same person decided and approved their own decision.
We run our own export shipments through twelve published checks across four gates — versioned, dated, free to cite. Use them on us.
The cheapest quote usually means thinner heating film, unrated batteries or no certification budget. The cost shows up later as returns, not as savings.
They don't. A CE certificate for one eye massager does not cover a different PCB or a different heating element.
Rechargeable heat products need UN38.3 and MSDS for shipping, plus a battery that holds capacity over hundreds of cycles. Ask for the cell supplier's spec.
Without a sealed reference sample you cannot resolve a quality dispute. Keep one signed sample from the approved batch.
Ask how the supplier handles a second run 12 months later: is the mould still available, is the heating film still sourced from the same vendor, is the firmware version archived?
