Classification of methamidophos under HS 2930.80
Methamidophos is a highly toxic organophosphorus insecticide classified under HS code 293080. This classification falls within Chapter 29 (Organic Chemicals), specifically under the heading for organo-sulphur compounds (2930). Methamidophos contains both phosphorus and sulfur atoms in its chemical structure, but the Harmonized System's hierarchical rules prioritize its status as an organo-sulphur compound. Specifically, 293080 was created to monitor and control the trade of this substance due to its inclusion in international environmental agreements like the Rotterdam Convention. The classification applies to the pure chemical or technically pure compound. If the methamidophos is prepared as a finished pesticide (e.g., mixed with surfactants, solvents, or put up for retail sale), the classification would shift to Chapter 38. However, for the bulk chemical substance, 293080 is the mandatory code. This ensures that customs authorities can track the movement of this hazardous substance for regulatory compliance and safety monitoring.

Codes often confused with 2930.80
Common mistake. The most common misclassification is HS code 380891, which covers insecticides put up in forms or packings for retail sale or as preparations. If the product is a ready-to-use spray or a formulated powder, it belongs in 3808, not 2930. Another error is using 2931, which covers 'other organo-inorganic compounds.' Since methamidophos contains a sulfur-carbon bond, it is specifically directed to 2930 by the chapter notes. Furthermore, it should not be confused with other organophosphates that do not contain sulfur, which would be classified elsewhere in Chapter 29.
Top exporters and importers of HS 293080 (the code used for methamidophos), 2025
In 2025, the largest exporter of HS 293080 (the code used for methamidophos) in UN Comtrade data was China, with 67% of world exports; the largest importer in UN Comtrade data was the United States, with 68% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 293080, not only methamidophos.

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).
