Common questions
- What is HTS code 2918?
- HTS heading 2918 covers carboxylic acids with additional oxygen function and their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulfonated, nitrated or nitrosated derivatives. It sits in Chapter 29 (organic chemicals) of the US Harmonized Tariff Schedule and contains 60 tariff lines.
- What is the duty rate for HTS 2918?
- General duty rates from 1% to 6.5%, with 11 duty-free lines. 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 2918 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.
