About heading 2904
Sulfonated, nitrated or nitrosated derivatives of hydrocarbons, whether or not halogenated
Heading 2904 covers sulfonated, nitrated and nitrosated derivatives of hydrocarbons, including halogenated versions of those derivatives. The heading splits first by the type of group added: subheadings 2904.10 for sulfo-only derivatives, 2904.20 for nitro-only or nitroso-only derivatives, 2904.31 through 2904.36 for perfluorooctane sulfonic acid and related compounds, and 2904.91 and 2904.99 for other mixed derivatives. Within each group, named chemical lines come before basket lines that separate aromatic from other products.

Frequently asked questions
What is the duty on trinitrotoluene?
Trinitrotoluene is classified under 2904.20.20.00 and the general (MFN) rate is Free.
How do I classify nitrated benzene or nitrated naphthalene?
Nitrated benzene, nitrated toluene other than p-nitrotoluene, and nitrated naphthalene go under 2904.20.35.00 at a general (MFN) rate of 5.5%. Chloropicrin, a nitrated halogenated hydrocarbon with a different structure, goes under 2904.91.00.00 at 3.7%.
