Common questions
- What is HTS code 8504?
- HTS heading 8504 covers electrical transformers, static converters (for example, rectifiers) and inductors; parts thereof. It sits in Chapter 85 (electrical machinery and electronics) of the US Harmonized Tariff Schedule and contains 49 tariff lines.
- What is the duty rate for HTS 8504?
- General duty rates from 1.6% to 6.6%, with 38 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 8504 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.
