Can a state reviewer require supporting evidence beyond a federal classification argument?

Can a state reviewer require supporting evidence beyond a federal classification argument?

The company publishes no position on what a state reviewer may require; what a state requires of a product sold within it is decided by that state, under its own law.

The company classifies its own article, and no agency has approved, registered or cleared it. A device is defined at 40 C.F.R. § 152.500(a) as “any instrument or contrivance (other than a firearm) intended for trapping, destroying, repelling, or mitigating any pest or any other form of plant or animal life (other than man and other than a bacterium, virus, or other microorganism on or in living man or living animals) but not including equipment used for the application of pesticides (such as tamper-resistant bait boxes for rodenticides) when sold separately therefrom.” NF Technical Products Inc. classifies the NanoFlashing™ Air Filter as a device under Section 2(h) of the Federal Insecticide, Fungicide, and Rodenticide Act, 7 U.S.C. § 136(h), and that definition. Its Statement of Classification states at 3.6 that a charge is a physical property, that it is not a substance or a mixture of substances, and that the filter therefore incorporates no substance or mixture of substances to perform its intended pesticidal purpose.

Under 40 C.F.R. § 152.500(b) a device is not required to be registered under FIFRA section 3, and 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). For the same filter in the European Union, C-POLAR Technologies, Inc. classifies it as neither a biocidal product nor a treated article under Regulation (EU) No 528/2012.
