This is the single most common point of failure. Many companies present themselves as factories while outsourcing assembly.
Start with the business license and check that the registered scope covers the manufacture of the relevant red light therapy bed equipment, rather than trade or technical consulting. Verify that the registered address matches the address on the quotation and the certification documents.
Then request a live video walkthrough rather than a photo gallery. Ask to see the SMT line or assembly benches, the aging and burn-in area, the darkroom or testing station used for irradiance measurement, and the packing area. A red light therapy bed supplier that cannot walk you through its own floor in real time is telling you something.
If the order value justifies it, commission a third-party factory audit. The cost is small relative to a container of red light therapy beds that fails on arrival.
