Products classified under Tariff item 2920.11.00.00
Methyl Parathion High Purity Reference Standard
This is a high-purity (99%+) methyl-parathion reference standard used for analytical testing and quality control in pesticide residue analysis. It is a separate chemically defined organic compound, specifically the thiophosphoric ester parathion-methyl, which falls squarely under tariff item 2920.11.00.
2920.11.00Parathion 80% Wettable Powder Technical
This is parathion technical material formulated as an 80% wettable powder for easier handling in manufacturing. Although formulated, it remains a thiophosphoric ester (parathion) and is classified under tariff item 2920.11.00, as the formulation does not alter its chemical identity.
2920.11.00Parathion Anhydrous Liquid 98%
This is anhydrous parathion liquid at 98% purity, stabilized with epichlorohydrin for safe transport. The stabilizer is added for safety and does not render the product for specific use, so it remains a separate chemically defined organic compound under tariff item 2920.11.00.
2920.11.00Parathion-Methyl (Methyl Parathion) 97% TC
This is methyl-parathion (ISO) technical concentrate at 97% purity, the primary form used for manufacturing emulsifiable concentrates. As a thiophosphoric ester specifically named in tariff item 2920.11.00, it is classified here regardless of its technical grade.
2920.11.00Parathion-Methyl Sodium Salt Solution 50%
This is an aqueous solution of parathion-methyl sodium salt at 50% active ingredient. Per Chapter 29 Note 1(d), products dissolved in water are covered by the chapter, and per Note 5(C)(1), inorganic salts of organic compounds are classified with the organic compound. Thus, it falls under tariff item 2920.11.00.
2920.11.00Parathion Technical Grade 95%
This is parathion technical grade at 95% purity, a highly toxic organophosphate insecticide. It is a separate chemically defined organic compound, specifically the thiophosphoric ester parathion, and is classified under tariff item 2920.11.00 as the named product.
