HS Code 2931.54 – Halogenated organo-phosphorous derivatives; trichlorfon (ISO)
HS code 2931.54 is the 6-digit subheading for halogenated organo-phosphorous derivatives, trichlorfon (ISO). It is used for trichlorfon, dipterex, neguvon, veterinary anthelmintic and agricultural insecticide.
What HS 2931.54 covers
HS code 293154 is dedicated to Trichlorfon (ISO), a well-known halogenated organo-phosphorous derivative. Trichlorfon is a broad-spectrum organophosphate insecticide and anthelmintic, widely used in agriculture for crop protection, in veterinary medicine for treating parasitic infections in livestock, and historically in public health for pest control. Its effectiveness comes with significant toxicity, leading to varying regulatory statuses globally, with some countries restricting or banning its use. Importers include agrochemical distributors, veterinary pharmaceutical companies, and public health organizations. Exporters are typically chemical manufacturers specializing in agrochemicals and veterinary products. Key trade considerations include regulatory compliance, safety handling, and environmental impact assessments.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
