HS Code for Methamidophos

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.

Products Included

• Technical grade methamidophos (pure)
• Methamidophos in bulk crystals or powder
• Methamidophos dissolved in an organic solvent (unmixed)
• Organo-sulphur compounds specifically identified as Methamidophos (ISO)

Common Misclassification

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.
