Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If part of organo-arsenic or other non-phosphorus organo-inorganic group
Broader organo-inorganic compounds later in 2931 cover non-phosphorus derivatives per heading structure.
If when diammonium phosphate-derived or used as fertilizer additive
Phosphorus compounds for fertilizers shift to Chapter 31 if primary agricultural end-use.
If imported as diluted solution with stabilizers for transport
Chapter notes exclude solutions rendered suitable for specific use beyond safety/transport.
