Heading 2903
Halogenated derivatives of hydrocarbons
76 declarable lines
Heading 2903 covers halogenated derivatives of hydrocarbons, meaning hydrocarbons where one or more hydrogen atoms have been replaced by fluorine, chlorine, bromine or iodine. The heading is split first by parent structure: acyclic (2903.11 to 2903.79), cyclanic, cyclenic or cycloterpenic (2903.81 to 2903.89), and aromatic (2903.91 to 2903.99). Acyclic lines are further split into saturated chlorinated, unsaturated chlorinated, saturated fluorinated, unsaturated fluorinated, brominated or iodinated, and compounds with two or more different halogens.
Products in this heading
- Methylene chloride (dichloromethane), a common paint stripper and solvent
- Chloroform (trichloromethane)
- Vinyl chloride monomer for PVC production
- HFC-134a (1,1,1,2-tetrafluoroethane), a refrigerant
- Methyl bromide (bromomethane), a fumigant
- Chlorobenzene and p-dichlorobenzene, moth control and chemical intermediates
- HCFC-22 (chlorodifluoromethane), a refrigerant and feedstock
- Perchloroethylene (tetrachloroethylene), a dry cleaning solvent
How to choose the right subheading
- Parent structure of the hydrocarbon: acyclic, cyclanic or cyclenic, or aromatic.
- Which halogens are present and whether the molecule is saturated or unsaturated.
- Whether two or more different halogens appear in the same molecule, which moves it to the 2903.7x group.
- The specific named compound, since many lines name the exact chemical (for example HFC-134a or HCFC-22).
- If no line names the compound, use the residual Other line of the matching group.
Often confused with
- Heading 2905Methanol and other acyclic alcohols
Hydrocarbons carrying an alcohol function are not halogenated hydrocarbons of 2903.
- Heading 2902Benzene and other unsubstituted cyclic hydrocarbons
The parent hydrocarbon without halogen substitution stays in 2902.
- Heading 2908Pentachlorophenol and other halogenated phenols
Halogenated derivatives of phenols are covered by the phenol derivative heading.
- Heading 2910Epichlorohydrin
It contains an epoxy function, so it is classified as an epoxide, not a halogenated hydrocarbon.
- Heading 2915Chloroacetic acid
Halogenated derivatives of carboxylic acids belong with the acids, not in 2903.
