Analysis
Subheading 8451.90 covers parts, within heading 8451. 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.
None of its 3 lines is duty-free at the general rate. Rates run from 3.5% to 3.5% with a median of 3.5%, so the line you choose sets the duty.
The US splits it as follows: 8451.90.30 for drying chambers for the drying machines of subheading 8451.21 or… (3.5%), 8451.90.60 for furniture designed to receive the drying machines of subheading… (3.5%) and 8451.90.90 for parts: other (3.5%).
By Census's concordance, most of its statistical lines are made by Major Household Appliance Manufacturing (335220) and Industrial Machinery Manufacturing (33324). Those are the NAICS industries a US producer of these goods would report under.
Goods only reach 8451.90 once they fall within heading 8451 (machinery (other than machines of heading 8450) for washing, cleaning, wringing, drying…). Under General Rule 6, subheadings are then compared only with others at the same level, so a product is matched against its siblings, not against lines elsewhere in the chapter.
