HSN code 2904 covers: Sulphonated, nitrated or nitrosated derivatives of hydrocarbons; whether or not halogenated.

Rates reflect the 22 Sep 2025 GST 2.0 reform (mainly 5% and 18%, with 3% for precious metals and 28%/40% for select sin and luxury goods). This is a reference drawn from the CBIC rate schedule, not tax advice — confirm the exact rate for your specific item with your CA.
