Last updated: August 2026 dataServing as the residual category for high-voltage electrical apparatus not captured by more specific headings, this classification covers a commercially diverse range of products including motor starters, overload protectors, terminals, splices, couplings, and other connectors rated above 1,000 V. The five US tariff lines — spanning motor starters (8535904000), terminals and splices (8535908020), connectors (8535908040), and two broader NESOI lines — require careful review of the article's primary function to determine the correct 10-digit classification. Mexico and Germany lead US supply, with China also a significant source; goods of Chinese origin in this heading may be subject to Section 301 measures. The breadth of this residual heading makes it a frequent target for CBP classification inquiries.

Classification within this heading turns on the article's primary function: 8535908040 covers electrical connectors specifically, while 8535908060 and 8535908090 capture switching and circuit protection apparatus and other apparatus not elsewhere specified. If the product's principal function is making a physical electrical connection rather than switching or protecting, 8535908040 is the more specific provision. A binding ruling from CBP is advisable for novel or hybrid-function devices.
Motor starters and motor overload protectors have a dedicated 10-digit provision (8535904000) within this heading. Entering them under a broader NESOI line could constitute a misclassification, potentially triggering penalties or post-entry corrections. Importers should confirm the article's rated voltage and function against the specific tariff line before filing.
