FDA cleared vs FDA registered PEMF: why almost nothing is cleared

Registration and listing are paperwork

"FDA registered" and "FDA listed" mean a company has told the FDA it exists and which products it makes, and paid a fee. The FDA does not review the device, test it, or agree that it works before a company can say this. There is no inspection of the claim behind it. So "FDA registered" on a PEMF page tells you the maker filed forms, nothing more. It is the same trap as a red light panel saying "FDA registered" rather than "cleared."

A 510(k) clearance is a real finding

A 510(k) clearance is different. The maker submits data to show the device is substantially equivalent to a legally marketed predicate device for a specific use, and the FDA reviews it and clears it for that use. It comes with a K-number you can look up in the FDA's public database. That is a real regulatory finding, tied to a specific indication, not a self-declaration. In PEMF, genuine 510(k) clearances are most common in medical bone-growth stimulators and are rare in consumer wellness devices.

Why so little consumer PEMF is cleared

Getting a 510(k) takes data, time, and money, and it locks you into specific claims. Many consumer PEMF brands instead sell as general wellness devices, which sidesteps the clearance process entirely, and then borrow credibility with "FDA registered" language. A few systems do hold real clearances, and when they do we credit it. The rest, the ones that headline registration or make no FDA claim at all, do not earn that credit, and the ones that dress registration up as a clearance get flagged.

How we score it

Our Regulatory Honesty dimension mirrors the red light rubric. A verified 510(k) clearance earns real credit. "FDA registered or listed" earns nothing and is flagged as paperwork, not a clearance. A device that makes no FDA claim at all actually scores slightly above one that markets registration as if it were a clearance, because it is not implying something it does not have. We also reward an electrical or EMC certification, such as FCC or CE, which is a genuine safety listing for a powered field-emitting device.

What to actually look for

Three checks. First, does the brand claim a 510(k) clearance with a K-number you can verify, or just "registered" or "listed"? Second, if it says "FDA-registered Class 1," read that as the lowest-oversight category and a self-declaration, not an endorsement. Third, separate the regulatory claim from the field-spec claim, a device can be honestly specified on its field and make no FDA claim, which is more trustworthy than a vague device waving registration around.
