Products classified under Tariff item 2903.29.00
1,3-Dichloropropene
1,3-Dichloropropene is a mixture of cis and trans isomers of an unsaturated dichlorinated acyclic hydrocarbon, used as a soil fumigant and chemical intermediate. It is a separate chemically defined organic compound or an isomer mixture, falling under Chapter 29 as an unsaturated chlorinated derivative of acyclic hydrocarbons.
1,4-Dichloro-2-butene
1,4-Dichloro-2-butene is a chemically defined unsaturated chlorinated acyclic hydrocarbon with a double bond and allylic chlorides, used as an intermediate in pharmaceutical synthesis. It falls under Chapter 29 as an unsaturated chlorinated derivative of acyclic hydrocarbons.
1-Chloro-1,3-butadiene (Chloroprene)
Chloroprene (2-chloro-1,3-butadiene) is a conjugated diene monomer used in the production of polychloroprene (Neoprene) synthetic rubber. It is a chemically defined unsaturated chlorinated acyclic hydrocarbon, falling under Chapter 29 as an unsaturated chlorinated derivative of acyclic hydrocarbons.
2,3-Dichloropropene
2,3-Dichloropropene is a pure chemically defined unsaturated chlorinated acyclic hydrocarbon with a double bond and adjacent chlorine substituents, used as a specialty intermediate. It is classified under Chapter 29 as an unsaturated chlorinated derivative of acyclic hydrocarbons.
3-Chloro-1-butyne
3-Chloro-1-butyne is a chemically defined unsaturated chlorinated acyclic hydrocarbon with a terminal alkyne and propargylic chloride, used as a specialty intermediate in organometallic coupling reactions. It falls under Chapter 29 as an unsaturated chlorinated derivative of acyclic hydrocarbons.
Allyl Chloride
Allyl chloride (3-chloro-1-propene) is a chemically defined unsaturated chlorinated derivative of acyclic propane with a terminal double bond and chlorine substituent. It is used as an industrial intermediate and falls under Chapter 29 as an unsaturated chlorinated derivative of acyclic hydrocarbons.
Crotonyl Chloride
Crotonyl chloride (2-butenoyl chloride) is an unsaturated acid chloride with a double bond and chlorine, but it is classified as a halide of a carboxylic acid. Per Chapter 29 Note 5(E), halides of carboxylic acids are classified with the corresponding acids, so it falls under heading 29.16, not 2903.
Trichloroethylene (Technical Grade)
Technical grade trichloroethylene contains unsaturated impurities, but trichloroethylene is a saturated chlorinated derivative of acyclic hydrocarbons (with a double bond? No, trichloroethylene has a double bond, so it is unsaturated). It is a chemically defined compound, but technical grade may contain impurities. It falls under Chapter 29 as an unsaturated chlorinated derivative of acyclic hydrocarbons.
Vinylidene Chloride
Vinylidene chloride (1,1-dichloroethene) is a chemically defined unsaturated chlorinated acyclic hydrocarbon with a double bond and two chlorine atoms on the same carbon. It is used as a monomer for polymers and falls under Chapter 29 as an unsaturated chlorinated derivative of acyclic hydrocarbons.
