Common questions
- What is HTS code 2904?
- HTS heading 2904 covers sulfonated, nitrated or nitrosated derivatives of hydrocarbons, whether or not halogenated. It sits in Chapter 29 (organic chemicals) of the US Harmonized Tariff Schedule and contains 31 tariff lines.
- What is the duty rate for HTS 2904?
- General duty rates from 3.7% to 5.5%, with 1 duty-free line. The general rate applies to most-favoured-nation trading partners; goods from countries with a free trade agreement may qualify for a reduced or duty-free special rate.
- How many digits does a full HTS code have?
- US import entries require the full 10-digit HTS code. Heading 2904 is the first four digits — the remaining six narrow it down to the specific product, which is what determines the duty rate you actually pay.
