Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing trace halogen impurities
Halogenated organo-phosphorus derivatives shift to other non-halogenated organo-inorganic compounds in 2931.90.
If dissolved in solvent for transport
Solutions in solvents for safety/transport fall outside Chapter 29 per note 2(e), moving to mixtures in Chapter 38.
If sold as pesticide intermediate without phosphorus emphasis
Certain phosphonate esters used in pesticides may classify under alcohol peroxides or ethers if principal function differs.
