About heading 8409

Heading 8409 covers parts suitable for use solely or principally with the engines of heading 8407 or 8408. It splits into 2 six-digit subheadings and 9 US tariff lines, 4 of which are duty-free under the general rate.

Headings are the four-digit level of the Harmonized System — the layer that is identical across all 160-plus countries that use it. The six-digit subheading is also international; the last two digits of each code here are US-specific and do not carry across to another country's tariff.
