HTS US: 2920.XX.XXXX
Description
This heading encompasses esters derived from inorganic acids of nonmetals, excluding esters of hydrogen halides, as well as their salts. It also includes halogenated, sulfonated, nitrated, or nitrosated derivatives of these esters. These compounds are primarily used in agricultural chemicals, pesticides, and various industrial applications.
Notable substances under this classification include:
- Parathion and parathion-methyl (methyl-parathion): Organophosphate pesticides widely used for insect control.
- Fenitrothion: An organophosphorus insecticide classified under other esters.
- Endosulfan: A chlorinated insecticide and acaricide.
- Phosphites: Including dimethyl, diethyl, trimethyl, and triethyl phosphite, which have applications in chemical synthesis and as intermediates.

What is NOT Classified Here?
To ensure precise classification, note these exclusions:
- Esters of hydrogen halides: These are excluded and classified under different headings.
- Organic esters not related to inorganic acids of nonmetals: Classified elsewhere.
- Other pesticide classes: Some pesticides not chemically falling under these esters are classified in other chapters.
Notes
- Regulatory Considerations: Many substances in this heading, such as parathion and endosulfan, are highly regulated or banned in various countries due to toxicity and environmental concerns.
- Tariff and Trade: Duty rates for chemicals under this heading vary widely depending on compound and end use. Importers should consult current tariff schedules and regulatory restrictions.
- Usage: These chemicals are mainly used in agriculture as pesticides or as intermediates in chemical manufacturing.
