Distilled Triethyl Phosphite BP Grade
Distilled triethyl phosphite of BP grade, a separate chemically defined organic compound (C6H15O3P), purified by fractional distillation to remove secondary phosphites. It is a phosphite ester of phosphorous acid, an inorganic acid of a non-metal, and therefore falls squarely under tariff item 2920.24.00.
