Ethylphosphonic dichloride
Ethylphosphonic dichloride (C2H5P(O)Cl2) is a halogenated organo-phosphorus compound where the phosphorus atom is bonded to one ethyl group and two chlorine atoms, with no further carbon atoms attached. It falls under HTS 2931.59.00.60 as a halogenated derivative containing a phosphorus atom bonded to one ethyl group. This chemical is used as an intermediate in synthesizing flame retardants and pesticides.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If unhalogenated phosphonate ester
Non-halogenated organo-inorganic phosphorus compounds without chlorine substitution classify under the broader organo-inorganic heading.
If classified primarily as organo-sulfur with incidental phosphorus
Organo-sulfur compounds take precedence; phosphorus present but sulfur linkage determines primary classification per Chapter 29 notes.
