How do US state rules apply?

In which states may each finished product be sold, and what current state records support that answer?

What a state requires of a product sold within it, of the party that sells it and of the records that party keeps is decided by that state, under its own law, with the party that places the product on that market.

The company sets out its classification under federal law and under Regulation (EU) No 528/2012. 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 40 C.F.R. § 152.500(a). 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). No agency has approved, registered or cleared the article; the company classifies it itself.

How would a state-specific claim restriction affect existing inventory, listings and downstream sellers?

A claim on a product, on a listing or on stock already sold is the responsibility of the party that made it.

The manufacturer and seller of a finished product are responsible for its design, manufacture, labeling, instructions, claims, sale, and warranty, except for a responsibility C-POLAR expressly accepts in a Separate Agreement. The Terms of Use state: “Nothing on the Site authorizes anyone to manufacture, integrate, market, resell, or describe a product as C-POLAR-enabled. Nothing authorizes anyone to describe itself as a C-POLAR partner. Written permission is required.”

The company publishes no state claim restriction of its own; a restriction of that kind is worked through by the sellers under the terms they have agreed.

What state-specific basis supports any claim that a federally framed device does not require a state product filing?

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).

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. 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.

The company makes no claim about state product filings; it sets out its classification under federal law and under Regulation (EU) No 528/2012. State rules apply on top of the federal rules. Each state decides, under its own law, what it requires of a product sold within it and of the party that sells it. The company classifies its own article. No agency has approved, registered or cleared the filter, and for a device there is no such approval to obtain, because EPA does not review a device for safety or efficacy before it is sold.

Does a reseller fulfilment warehouse create obligations in a state where the brand has no office?

What a state requires of a product sold within it, of the party that sells it and of the records that party keeps is decided by that state, under its own law, with the party that places the product on that market.

The company sets out its classification under federal law and under Regulation (EU) No 528/2012. 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 40 C.F.R. § 152.500(a). 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). No agency has approved, registered or cleared the article; the company classifies it itself.

Every commercial NanoFlashing™ product is made by a manufacturing partner, in their facility, in their format. NanoFlashing™ is a technology; the name, rating and sale of a product that carries it are set by that product's maker and seller. NF Technical Products Inc. accepts that each requirement listed at 40 C.F.R. § 152.500(b) applies to the NanoFlashing™ Air Filter.

Would changing a product's name while keeping its construction require a state record update?

A change to what is said about a product is handled by the party that says it, and on this site it is handled by publishing the changed page.

Each answer here carries the date it was last reviewed, and when its wording changes, the answer carries the new text and a new review date. The Terms of Use state: “Site Content may become outdated after the publication or review date shown with it,” and: “Nothing on the Site authorizes anyone to manufacture, integrate, market, resell, or describe a product as C-POLAR-enabled. Nothing authorizes anyone to describe itself as a C-POLAR partner. Written permission is required.”

A change to a name, a claim or an intended use on a finished product is assessed for that product by the party that makes and sells it, under the rules of the market it is sold in. A materials review or a wording request is arranged in writing, through [email protected] on the Contact page.

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

What a state requires of a product sold within it is decided by that state, under its own law. 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.

The company classifies its own article. No agency has approved, registered or cleared the filter, and for a device there is no such approval to obtain, because EPA does not review a device for safety or efficacy before it is sold.
