Last updated: August 2026 dataTefluthrin, a pyrethroid insecticide active ingredient carved out at 2916201000, anchors the named-compound line within this heading, while the broad residual line (2916205000) captures naphthenic acids, cyclopentanecarboxylic acid derivatives, and other alicyclic monocarboxylic intermediates used in lubricant additives, agrochemicals, and specialty resins. India leads US supply, followed by Australia and Mexico. Pyrethroid intermediates like tefluthrin may be subject to EPA pesticide import requirements, and the wide chemical diversity of the residual line makes precise structural documentation essential for correct classification.

CBP expects a complete chemical name, CAS registry number, and structural formula on the commercial invoice. For compounds that could plausibly fall under a named line (such as tefluthrin at 2916201000), importers must confirm the ISO or IUPAC identity. When the product is a mixture or technical-grade material, a certificate of analysis showing active ingredient content is also advisable.
Yes. Tefluthrin is a registered pesticide active ingredient, and imports are subject to EPA FIFRA requirements. Shipments must comply with EPA registration conditions, and importers should be prepared to provide documentation of the foreign registrant's authorization. Consult a licensed customs broker familiar with pesticide import procedures before shipment.
