Subheadings
Products classified under Tariff item 2920.22
Bulk Diethyl Phosphite in ISO Tanks
Bulk diethyl phosphite shipped in ISO tanks for industrial chemical distribution. The product is a separate chemically defined organic compound of heading 29.20, and the ISO tank is transport packaging that does not alter its classification.
2920.22.00Diethyl Phosphite
Diethyl phosphite, a colorless liquid organophosphorus compound with the formula (C2H5O)2P(O)H, is a separate chemically defined phosphite ester of an inorganic acid of a non-metal. It meets the Chapter 29 criteria for classification under heading 29.20.
2920.22.00Diethyl Phosphite 98% Technical Grade
Technical grade diethyl phosphite at 98% purity is a separate chemically defined compound, even with minor impurities. It is used in industrial synthesis of herbicides like glyphosate intermediates and falls under heading 29.20 as a phosphite ester.
2920.22.00Diethyl Phosphite Flame Retardant Intermediate
Diethyl phosphite used as an intermediate for synthesizing phosphorus-based flame retardants is a separate chemically defined compound. Its end use does not affect classification under heading 29.20, which covers phosphite esters by chemical identity.
2920.22.00Diethyl Phosphite for Glyphosate Synthesis
High-purity diethyl phosphite specifically for glyphosate synthesis is a separate chemically defined compound. The intended use in agrochemical production does not change its classification under heading 29.20.
2920.22.00Diethyl Phosphite with 50ppm BHT Stabilizer
Diethyl phosphite with 50 ppm BHT stabilizer is a separate chemically defined compound with an added stabilizer necessary for preservation. Under Chapter 29 Note 1(f), such additions do not remove the product from heading 29.20.
2920.22.00Distilled Diethyl Phosphite 99.5% Purity
Vacuum-distilled diethyl phosphite at 99.5% purity is a separate chemically defined compound. High purity does not affect classification under heading 29.20, which covers phosphite esters regardless of purity level.
2920.22.00Stabilized Diethyl Phosphite with MEHQ Inhibitor
Diethyl phosphite stabilized with 100 ppm MEHQ inhibitor is a separate chemically defined compound with an added stabilizer for preservation. Chapter 29 Note 1(f) permits such additions without changing the classification under heading 29.20.
