Import, export and country of origin

What records connect the imported shipment to the correct manufacturer, product and market requirements?

What connects a shipment to the article is what the article itself carries, and the records of a shipment are the importer's.

The company's label for the NanoFlashing™ Air Filter carries the product name, the panel filter description, the net contents, the nominal size, the net weight, the rated airflow, the maximum face velocity, and a company name and address. The filings a device shipment requires are set out in the regulations: a Notice of Arrival of Pesticides and Devices, EPA Form 3540-1, under 19 C.F.R. § 12.112(a), and the books and records of devices produced, received, shipped and in stock under 40 C.F.R. § 169.2(b) to (e).

The manufacturer and seller of a finished product are responsible for its design, manufacture, labeling, instructions, claims, sale, and warranty. NanoFlashing™ is a technology; the name, rating and sale of a product that carries it are set by that product's maker and seller.

The manufacturer and seller of a finished product are responsible for its design, manufacture, labeling, instructions, claims, sale, and warranty.

Whether a step of manufacture is enough to change origin, and what a finished assembly must declare, are decided under the rules of the place where the declaration is made, by the party that makes it.

Can a shipment described as filter material be challenged if its promotional claims indicate another category?

The company publishes no position on how a customs or other authority would treat a shipment; it classifies the NanoFlashing™ Air Filter itself, as a device, 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. NanoFlashing™ is a technology; the name, rating and sale of a product that carries it are set by that product's maker and seller.

Would re-export of rejected stock require permission from the destination authority?

The company publishes no re-export position for rejected stock.

A question of that kind is decided by the party that moves the goods, under the rules of the places it moves them between, and the company publishes no customs or export position.

C-POLAR markets a materials technology. Every commercial NanoFlashing™ product is made by a manufacturing partner, in their facility, in their format. The Terms of Use state: “The Site does not sell products or accept orders. These Terms do not govern the sale, delivery, installation, return, warranty, or use of a finished product,” and: “Accessing the Site or contacting C-POLAR through the Site does not create a partnership, agency, joint venture, distribution right, supply commitment, license, exclusive right, or other business relationship.”

A tariff heading, a declared value, an origin statement, a temporary-import procedure, a screening step and the terms that allocate clearance are matters for the importer or exporter of record and for the agreement between the parties to the shipment. The company does not give legal advice and does not comment on how a case would be decided.
