9021.40.00

Analysis

HTS 9021.40.00 covers hearing aids, excluding parts and accessories thereof under heading 9021 (orthopedic appliances, including crutches, surgical belts and trusses; splints and other…).

Goods from countries without normal trade relations pay the column 2 rate of 35% instead of nothing, so origin decides between free entry and a 35% duty.

Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 73% of the 296 tariff lines in chapter 90. Duty-free at the general rate does not rule out additional duties under Chapter 99, such as Section 301 or Section 232 measures, which depend on the country of origin.

Census statistics map these goods to NAICS 334510 (Electromedical and Electrotherapeutic Apparatus Manufacturing), an industry of 892 US establishments employing 94,361 people. That is the industry code a US manufacturer of the same product would normally use.

All 10 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.

Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
