Common questions

What is HTS code 8544?
HTS heading 8544 covers insulated (including enameled or anodized) wire, cable (including coaxial cable) and other insulated electric conductors, whether or not fitted with connectors; optical fiber cables, made up of individually sheathed fibers, whether or not assembled with electric conductors or fitted with connectors. It sits in Chapter 85 (electrical machinery and electronics) of the US Harmonized Tariff Schedule and contains 19 tariff lines.
What is the duty rate for HTS 8544?
General duty rates from 2.6% to 5.3%, with 4 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 8544 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.
