9021

Analysis

Heading 9021 of the Harmonized Tariff Schedule covers orthopedic appliances, including crutches, surgical belts and trusses; splints and other fracture appliances; artificial parts of the body; hearing aids and other appliances which are worn or carried, or implanted in…. It divides into 8 six-digit subheadings and 11 eight-digit tariff lines, with 13 ten-digit statistical suffixes below them.

Every one of its 11 tariff lines is duty-free at the general rate, so classification within the heading affects statistics and Chapter 99 measures rather than the base duty.

The largest subheadings are 9021.21 (artificial teeth and parts and accessories thereof, 2 lines), 9021.29 (other, 2 lines), 9021.90 (other, 2 lines) and 9021.10 (unnamed, 1 line).

Its median rate of duty-free sits at the 37th percentile of the headings in chapter 90.

By Census's concordance, most of its statistical lines are made by Surgical Appliance and Supplies Manufacturing (339113), Dental Laboratories (339116) and Electromedical and Electrotherapeutic Apparatus Manufacturing (334510). Those are the NAICS industries a US producer of these goods would report under.
