HS Code for Chlorobenzene

Chlorobenzene, along with its dichlorinated isomers, is classified under HS code 2903.91. This classification is situated in Chapter 29 (Organic Chemicals) under heading 2903, which covers halogenated derivatives of hydrocarbons. The system distinguishes between acyclic hydrocarbons and cyclic hydrocarbons. Chlorobenzene is an aromatic cyclic hydrocarbon where one or more hydrogen atoms on the benzene ring have been replaced by chlorine. Subheading 2903.91 is a specific category that groups together chlorobenzene (monochlorobenzene), o-dichlorobenzene, and p-dichlorobenzene. The classification is determined by the aromatic nature of the parent benzene ring and the specific halogenation. These substances are widely used as high-boiling solvents in industrial processes and as intermediates in the synthesis of dyes and pesticides.

Products Included

• Monochlorobenzene
• o-Dichlorobenzene (1,2-dichlorobenzene)
• p-Dichlorobenzene (1,4-dichlorobenzene)
• Chlorobenzene for solvent use
• Benzene chloride
• Phenyl chloride

Common Misclassification

A common misclassification occurs with HS code 2903.61 in older versions of the nomenclature or confusion with other halogenated derivatives like benzyl chloride (2903.99). Another frequent error involves p-dichlorobenzene when sold as mothballs or air fresheners; in such cases, it may be classified under 3808 as an insecticide or 3307 as a room deodorizer if put up for retail sale. However, as a pure chemical substance, 2903.91 is the correct heading. It should also not be confused with chlorotoluenes, which fall under 2903.99.

FAQ

What is the HS code for chlorobenzene?

The HS code for chlorobenzene, o-dichlorobenzene, and p-dichlorobenzene is 2903.91.

Is paradichlorobenzene (mothballs) covered under this code?

Yes, in its bulk chemical form, paradichlorobenzene is classified under 2903.91, though retail-packaged mothballs may fall under 3808.
