Analysis
Subheading 8421.91 covers of centrifuges, including centrifugal dryers, within heading 8421. The first six digits are shared by every country that uses the Harmonized System, so this part of the code is the same in the US, UK and EU schedules; the 3 US tariff lines below it are national.
Every one of its 3 tariff lines is duty-free at the general rate, so classification within the subheading affects statistics and Chapter 99 measures rather than the base duty.
The US splits it as follows: 8421.91.20 for drying chambers for the clothes-dryers of subheading 8421.12 and… (duty-free), 8421.91.40 for furniture designed to receive the clothes-dryers of subheading 8421.12 (duty-free) and 8421.91.60 for of centrifuges, including centrifugal dryers: other (duty-free).
By Census's concordance, most of its statistical lines are made by Major Household Appliance Manufacturing (335220) and All Other General Purpose Machinery Manufacturing (33399). Those are the NAICS industries a US producer of these goods would report under.
