Products classified under HTS 2903.29.00.00
Vinylidene Chloride
Vinylidene chloride (1,1-dichloroethene) is an unsaturated chlorinated derivative of an acyclic hydrocarbon, featuring a carbon-carbon double bond and two chlorine atoms on the same carbon. It falls under HTS 2903.29.00.00 as it matches the chapter's definition for separate chemically defined organic compounds that are halogenated derivatives of hydrocarbons. Primarily used as a comonomer in polyvinylidene chloride (PVDC) resins for food packaging films.
Allyl Chloride
Allyl chloride (3-chloro-1-propene) is an unsaturated chlorinated derivative of acyclic propane with a terminal double bond and chlorine substituent. Classified under HTS 2903.29.00.00 as a chemically defined halogenated hydrocarbon per chapter notes. Key intermediate for epichlorohydrin, allyl alcohol, and glycidyl ethers in resins and pharmaceuticals.
Crotonyl Chloride
Crotonyl chloride (2-butenoyl chloride) combines acid chloride functionality with α,β-unsaturation and chlorine, but classified by halide nature. HTS 2903.29.00.00 per note 5(E) classifying acid halides with corresponding acids. Reactive intermediate for pharmaceuticals and polymer synthesis.
2,3-Dichloropropene
2,3-Dichloropropene features both double bond and adjacent chlorine substituents on acyclic C3 chain. Pure chemically defined compound under HTS 2903.29.00.00. Intermediate for pharmaceutical synthesis and specialty polymer modifiers.
1-Chloro-1,3-butadiene (Chloroprene)
Chloroprene (2-chloro-1,3-butadiene) is the conjugated diene monomer for polychloroprene (Neoprene) synthetic rubber. Classified HTS 2903.29.00.00 as unsaturated chlorinated acyclic hydrocarbon. Stabilized with phenolic antioxidants for storage and transport.
Trichloroethylene (Technical Grade)
Technical grade trichloroethylene contains unsaturated impurities distinguishing from pure saturated form. HTS 2903.29.00.00 for unsaturated chlorinated derivatives per chapter note 2(a). Industrial solvent for metal degreasing despite phaseout pressures.
1,4-Dichloro-2-butene
1,4-Dichloro-2-butene is a bifunctional unsaturated chlorinated compound used in pharmaceutical synthesis. Chemically defined under HTS 2903.29.00.00 with characteristic C=C and allylic chlorides. Intermediate for contrast agents and antivirals.
3-Chloro-1-butyne
3-Chloro-1-butyne features terminal alkyne unsaturation with propargylic chloride. Rare unsaturated chlorinated acetylenic hydrocarbon under HTS 2903.29.00.00. Specialty intermediate for organometallic coupling reactions.
1,3-Dichloropropene
1,3-Dichloropropene is a mixture of cis/trans isomers of an unsaturated di-chlorinated acyclic hydrocarbon with conjugated double bond system. Falls under HTS 2903.29.00.00 per chapter note 2(b) for isomer mixtures of same compound. Used as soil fumigant (Telone) in agriculture despite toxicity concerns.
