Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If ethyl homolog (O-ethyl methylphosphonochloridate)
Different alkyl chain length changes specific compound identification within same subheading group
If classified by chloride function without considering P-C bond
Erroneous classification as simple alkyl chloride ignores organo-phosphorus Chapter 29 priority
If imported as solution in inert solvent exceeding transport limits
Solutions beyond safety/transport exceptions fall to mixtures in Chapter 38
