9021.90

Analysis

Subheading 9021.90 covers other, within heading 9021. 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 2 US tariff lines below it are national.

Every one of its 2 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: 9021.90.40 for parts and accessories for hearing aids and for pacemakers for… (duty-free) and 9021.90.81 for other: other (duty-free).

By Census's concordance, most of its statistical lines are made by Electromedical and Electrotherapeutic Apparatus Manufacturing (334510) and Surgical Appliance and Supplies Manufacturing (339113). Those are the NAICS industries a US producer of these goods would report under.

Goods only reach 9021.90 once they fall within heading 9021 (orthopedic appliances, including crutches, surgical belts and trusses; splints and other…). 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.
