Common questions
- What is HTS code 2933?
- HTS heading 2933 covers heterocyclic compounds with nitrogen hetero-atom(s) only. It sits in Chapter 29 (organic chemicals) of the US Harmonized Tariff Schedule and contains 127 tariff lines.
- What is the duty rate for HTS 2933?
- General duty rates from 3.5% to 6.5%, with 34 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 2933 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.
