9018

Analysis

Heading 9018 of the Harmonized Tariff Schedule covers instruments and appliances used in medical, surgical, dental or veterinary sciences, including scintigraphic apparatus, other electro-medical apparatus and sight-testing instruments; parts and accessories thereof. It divides into 13 six-digit subheadings and 28 eight-digit tariff lines, with 42 ten-digit statistical suffixes below them.

Every one of its 28 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 9018.90 (other instruments and appliances and parts and…, 10 lines), 9018.19 (other, 4 lines), 9018.11 (electrocardiographs, and parts and accessories…, 3 lines) and 9018.49 (other, 2 lines).

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 Electromedical and Electrotherapeutic Apparatus Manufacturing (334510), Surgical and Medical Instrument Manufacturing (339112) and Dental Equipment and Supplies Manufacturing (339114). Those are the NAICS industries a US producer of these goods would report under.
