Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alkyl chains exceed C10 limit
Longer alkyl chains fall under the residual 'other' halogenated organo-phosphorus derivatives in 2931.59.0050
If not containing fluorine
Non-halogenated organo-inorganic phosphorous compounds classify under 2931.90.3000
