Common questions
- What is HTS code 2836?
- HTS heading 2836 covers carbonates; peroxocarbonates (percarbonates); commercial ammonium carbonate containing ammonium carbamate. It sits in Chapter 28 (inorganic chemicals) of the US Harmonized Tariff Schedule and contains 15 tariff lines.
- What is the duty rate for HTS 2836?
- General duty rates from 0.5% to 5.5%, with 2 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 2836 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.
