9030.90

Analysis

Subheading 9030.90 covers parts and accessories, within heading 9030. 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 6 US tariff lines below it are national.

Every one of its 6 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: 9030.90.25 for printed circuit assemblies (duty-free), 9030.90.46 for for articles of subheading 9030.10: other (duty-free), 9030.90.66 for of instruments and apparatus of subheading 9030.40 or 9030.82 (duty-free), 9030.90.68 for printed circuit assemblies: other (duty-free), 9030.90.84 for of instruments and apparatus of subheading 9030.82 (duty-free) and 9030.90.89 for other: other (duty-free).

By Census's concordance, most of its statistical lines are made by Instrument Manufacturing for Measuring and Testing Electricity and Electrical Signals (334515), Printed Circuit Assembly (Electronic Assembly) Manufacturing (334418) and Other Measuring and Controlling Device Manufacturing (334519). Those are the NAICS industries a US producer of these goods would report under.
