Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified by phosphoric acid function
Phosphoric esters without nitrogen-dominant function may fall under heading 2919.
If amine function predominates over P-F
Amine salts or derivatives without phosphorus classification shift to heading 2921.
If formulated as pesticide intermediate
If put up for pesticidal use rather than pure chemical, moves to Chapter 38.
