Bis(2-Chlorovinyl)Chloroarsine
Bis(2-chlorovinyl)chloroarsine is a highly toxic organo-arsenic compound containing arsenic directly linked to carbon atoms, classified under HTS 2931.90.90.35 as an other organo-inorganic compound. It falls within Chapter 29 per the notes for separate chemically defined organic compounds with nonmetal atoms like arsenic bonded to carbon, excluding sulfonated or halogenated derivatives covered elsewhere.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified primarily by arsenic content rather than organic structure
Compounds containing arsenic might shift to Chapter 28 if inorganic characteristics dominate over organo-inorganic carbon linkages per Chapter 29 notes.
If for other organo-arsenic compounds not specifically enumerated
If not precisely matching the bis(2-chlorovinyl)chloroarsine specification, it could fall under the broader organo-arsenic subheading within the same heading.
If imported for government or laboratory research use
Certain toxic chemicals for non-commercial, scientific purposes may qualify for duty-free entry under special tariff provisions, bypassing standard Chapter 29 classification.

Import Tips & Compliance
• Obtain prior approval from BIS or ATF due to chemical weapons precursor status; include detailed safety data sheets and toxicity profiles in documentation
• Verify end-use statements to avoid dual-use export control violations
• Common pitfall: inadequate labeling of arsenic content leading to CBP holds
