Permethrin

Permethrin (CAS 52645-53-1, EC 258-067-9) is a synthetic pyrethroid insecticide and acaricide commercially available under trade names including Nix, COOPEX, AMBUSH, DRAGON, and S 3151. It carries no assigned E-code and is classified under HS code 29162090.

In agricultural applications, permethrin disrupts sodium channel function in insect nervous systems, causing paralysis and death in target pests on crops and livestock. In textile and leather processing, it is applied as a durable fabric treatment to confer insect-repellent and flame-retardant properties, with efficacy retained through multiple wash cycles.

Permethrin is supplied as a crystalline solid and in technical-grade or formulation-ready concentrations depending on end-use requirements. It is subject to REACH registration obligations within the EU and falls under Biocidal Products Regulation (BPR) for relevant product types. Procurement teams should confirm current authorisation status for their specific application and jurisdiction before ordering.
