Common questions

What is HTS code 8542?
HTS heading 8542 covers electronic integrated circuits; parts thereof. It sits in Chapter 85 (electrical machinery and electronics) of the US Harmonized Tariff Schedule and contains 31 tariff lines.
What is the duty rate for HTS 8542?
Duty-free under the general rate. 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 8542 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.
