U.S. imports of parts and accessories for electrical measurement, checking, and ionizing radiation instruments (HS 903090) totaled $92.4M in April 2026, traded with 66 countries.
Importers of Parts and Accessories for Electrical Measurement, Checking, and Ionizing Radiation Instruments paid $9.2M in duties in April 2026 — an effective duty rate of 12% on $78.6M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataParts and accessories for the full range of heading 9030 instruments — from printed circuit assemblies for radiation detectors to mechanical components for semiconductor testers — are organized across more than a dozen 10-digit US tariff lines that map directly to the parent instrument subheading. The granular structure means that a printed circuit assembly for a semiconductor wafer instrument (9030906600) carries a different classification than one for a general recording instrument (9030906800), so correct identification of the parent instrument is the first classification step. Malaysia, Taiwan, and Germany are the leading US import sources for this parts category. Importers should note that parts subject to Section 301 tariffs on goods of Chinese origin remain a compliance consideration even when the finished instrument itself is sourced elsewhere.

The correct line depends on which parent instrument subheading the PCB is designed for. For example, printed circuit assemblies for semiconductor wafer instruments fall under 9030906600, while those for other recording instruments fall under 9030906800. The importer should identify the finished instrument's subheading first, then match it to the corresponding parts line. Technical documentation linking the PCB to a specific instrument model and its HTS classification is essential.
Generally no — once an article is identifiable as a part or accessory of a heading 9030 instrument, it belongs in the parts subheading (903090) rather than the instrument subheading itself. The exception would be if the part is more specifically described elsewhere in the tariff schedule. GRI 1 and the relevant section and chapter notes govern, and CBP has historically been strict about keeping parts in the parts provision.
