Analysis
Heading 8411 of the Harmonized Tariff Schedule covers turbojets, turbopropellers and other gas turbines, and parts thereof. It divides into 8 six-digit subheadings and 16 eight-digit tariff lines, with 27 ten-digit statistical suffixes below them.
13 of its 16 lines with a percentage rate are duty-free at the general rate (81%) and 3 are dutiable, from duty-free up to 2.5%. The median line pays duty-free.
The largest subheadings are 8411.11 (of a thrust not exceeding 25 kN, 2 lines), 8411.12 (of a thrust exceeding 25 kN, 2 lines), 8411.21 (of a power not exceeding 1,100 kW, 2 lines) and 8411.22 (of a power exceeding 1,100 kW, 2 lines).
Its median rate of duty-free sits at the 30th percentile of the headings in chapter 84.
By Census's concordance, most of its statistical lines are made by Turbine and Turbine Generator Set Units Manufacturing (333611) and Aircraft Engine and Engine Parts Manufacturing (336412). Those are the NAICS industries a US producer of these goods would report under.
