Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If organo-phosphorus compound with P-C bond
Heading 2931 covers organo-inorganic compounds with nonmetals like phosphorus directly linked to carbon.
If formulated as finishing agent for textiles
Preparations used as finishing agents exclude from Chapter 29 per general exclusions.
If derived from phosphoric acid esters
Phosphoric esters classify in 2919 before amine salts per subchapter ester rules (note on esters).
