Analysis
Heading 8421 of the Harmonized Tariff Schedule covers centrifuges, including centrifugal dryers; filtering or purifying machinery and apparatus, for liquids or gases; parts thereof. It divides into 12 six-digit subheadings and 14 eight-digit tariff lines, with 24 ten-digit statistical suffixes below them.
11 of its 14 lines with a percentage rate are duty-free at the general rate (79%) and 3 are dutiable, from duty-free up to 2.5%. The median line pays duty-free.
The largest subheadings are 8421.91 (of centrifuges, including centrifugal dryers, 3 lines), 8421.11 (unnamed, 1 line), 8421.12 (unnamed, 1 line) and 8421.19 (unnamed, 1 line).
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 All Other General Purpose Machinery Manufacturing (33399), Industrial and Commercial Fan and Blower and Air Purification Equipment Manufacturing (333413) and Major Household Appliance Manufacturing (335220). Those are the NAICS industries a US producer of these goods would report under.
