Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If O-alkyl ester chain exceeds C10
Subheading limits O-alkyl esters to ā¤C10; longer chains fall under other non-halogenated phosphorous derivatives.
If for the free alcohol precursor without phosphorus
The corresponding amino-alcohol without phosphonite group classifies as alcohol amines in Chapter 29 heading 2909.
If imported as mixture with solvents exceeding safety/transport limits
Chapter note (e) excludes solutions where solvent renders product suitable for specific use beyond general purposes.
