Chloropicrin — also known as trichloronitromethane — is a soil fumigant and tear-gas agent with a single US tariff line at 2904910000. EPA regulates its use as a pesticide under FIFRA, and imports must comply with EPA pesticide registration requirements in addition to standard CBP entry. China is the leading US supplier, followed by Japan and India, making supply concentration a notable risk consideration for agricultural distributors who rely on it for pre-plant soil treatment in high-value crops.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes. Chloropicrin is a registered pesticide under FIFRA, and imported product must conform to an EPA-registered label. Importers may also need to comply with EPA's pesticide import notification procedures, and shipments are subject to EPA sampling at the port of entry.
Chloropicrin is specifically enumerated at the HS6 level (2904.91) as a named compound, separating it from the broader 'other' category at 2904.99. Its unique combination of both halogen (chloro) and nitro substituents on a single carbon, along with its distinct end-use profile as a fumigant, justifies this dedicated classification.
