Common questions
- What is HTS code 3824?
- HTS heading 3824 covers prepared binders for foundry molds or cores; chemical products and preparations of the chemical or allied industries (including those consisting of mixtures of natural products), not elsewhere specified or included. It sits in Chapter 38 (miscellaneous chemicals) of the US Harmonized Tariff Schedule and contains 48 tariff lines.
- What is the duty rate for HTS 3824?
- General duty rates from 2.8% to 6.5%, with 9 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 3824 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.
