Importers of Electrical Machines & Apparatus with Individual Functions, N.E.S. paid $101.3M in duties in August 2026, an average duty rate of 7.72% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataElectrical machines and apparatus classified here perform discrete, self-contained functions not captured by any more specific SITC heading — a deliberately broad residual category that in practice captures a wide range of industrial and commercial equipment such as ion implanters, electroplating rectifiers, and specialized test apparatus. The catch-all nature of this heading makes it a frequent site of classification disputes, since CBP may argue that a product belongs under a more specific provision. Section 301 tariffs apply to many Chinese-origin goods that land here, amplifying the financial stakes of correct classification.

A product qualifies here only when it cannot be classified under a more specific SITC or HTS provision. The 'individual functions' concept means the machine performs a defined, self-contained electrical task. Importers should document why no more specific heading applies — CBP binding rulings are advisable for high-value or recurring shipments to lock in the classification.
Because this heading covers a wide variety of electrical apparatus, the applicable Section 301 list and rate depend on the specific HTS subheading at the 8- or 10-digit level, not the SITC heading alone. Importers should map each product to its precise HTS code and verify which Section 301 annex applies, as different apparatus types within this broad category may fall on different lists.
