Technical grade triethyl phosphite at 97% purity, packaged in 200 kg drums for bulk chemical import. It is a separate chemically defined organic compound under tariff item 2920.24.00, used primarily in flame retardant manufacturing, and meets the classification criteria of Chapter 29 note 1(a).
2920.24.00Triethyl Phosphite
Triethyl phosphite, a colorless liquid organophosphorus compound with the formula P(OCH2CH3)3, is a separate chemically defined organic compound. It is classified under tariff item 2920.24.00 as a phosphoric ester derivative, specifically triethyl phosphite, and is a key reagent in organic synthesis.
2920.24.00Triethyl Phosphite 98% Technical Grade
Technical grade triethyl phosphite at 98% purity, used in industrial synthesis of herbicides and stabilizers. It is a separate chemically defined organic compound under tariff item 2920.24.00, and minor impurities do not affect its classification per Chapter 29 note 1(a).
2920.24.00Triethyl Phosphite for Pesticide Synthesis
Industrial triethyl phosphite specified for glyphosate synthesis. Despite its end use, it is classified under tariff item 2920.24.00 as a separate chemically defined organic compound, per Chapter 29 note 1(a), which prioritizes chemical definition over application.
2920.24.00Triethyl Phosphite in Ethanol Solution 50%
Triethyl phosphite dissolved in ethanol at 50% concentration for safe handling and transport. The solution is a normal and necessary method of putting up the product for safety, and the solvent does not render it suitable for a specific use, so it is classified under tariff item 2920.24.00 per Chapter 29 note 1(e).
2920.24.00Triethyl Phosphite Stabilized with BHT
Triethyl phosphite stabilized with butylated hydroxytoluene (BHT) for safe transport and storage. The stabilizer is necessary for preservation, so the product is classified under tariff item 2920.24.00 per Chapter 29 note 1(f).
2920.24.00Triethyl Phosphite with Anti-Dusting Agent
Triethyl phosphite with an added anti-dusting agent for bulk handling safety. The additive does not render the product particularly suitable for a specific use, so it remains classified under tariff item 2920.24.00 per Chapter 29 note 1(g).
2920.24.00Triethyl Phosphite with MEHQ Inhibitor
Triethyl phosphite inhibited with 4-methoxyphenol (MEHQ) to prevent polymerization. The stabilizer is necessary for preservation or transport, so the product remains classified under tariff item 2920.24.00 per Chapter 29 note 1(f).
