U.S. imports of parts of electrical machines & apparatus with individual functions, n.e.s. (SITC 77879) totaled $97.7M in April 2026, traded with 63 countries.
Importers of Parts of Electrical Machines & Apparatus with Individual Functions, N.E.S. paid $13.1M in duties in April 2026 — an effective duty rate of 18% on $70.9M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataReplacement and service parts for the broad class of individually functioning electrical machines — including subassemblies, printed circuit boards, and mechanical housings specific to apparatus in the parent heading — are grouped here when no more specific parts provision applies. Correct classification requires demonstrating that the part is principally used with apparatus of the parent heading rather than with a more specifically described machine. For high-value capital equipment, misclassifying a part under this residual heading rather than a dedicated parts provision can affect both duty liability and eligibility for certain trade programs.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The importer should provide technical documentation — engineering drawings, OEM part numbers, and a statement of principal use — showing that the article is designed and used exclusively or principally with apparatus classifiable in the parent 'individual functions' heading. If the parent machine has its own dedicated parts subheading at the HTS level, that more specific provision takes precedence.
Possibly, but PCBAs are subject to their own classification rules: if the board is identifiable as a part of a specific machine in the parent heading and no more specific PCBA provision applies, it may classify here. However, bare PCBs and certain populated boards have dedicated HTS provisions that may take precedence. A CBP binding ruling is the most reliable way to confirm classification for high-volume PCBA imports.
