Can a reported absence of registrations be reproduced in a documented primary-source search with a defined date and scope?

Yes.

EPA's own registration record is public and can be searched by anyone, on any date. The Pesticide Product and Label System, at https://ordspub.epa.gov/ords/pesticides/f?p=PPLS:1, describes itself as providing “a collection of pesticide product labels that have been accepted by EPA under Section 3 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)”, and it can be searched by EPA registration number, by company name or by company number. A device is not required to be registered under FIFRA section 3: that is what 40 C.F.R. § 152.500(b) says. The requirements that apply instead are labelling; establishment registration and reporting; books and records; inspection of establishments; violations, enforcement and penalties; import and export; child-resistant packaging; and the Agency's authority under FIFRA section 25(c)(4). So there is no section 3 registration for a device to find, and finding none is the expected result rather than a discrepancy. The absence of a registration is not an approval either. No agency has approved, registered or cleared the NanoFlashing™ Air Filter. The company classifies the article itself.
