U.S. exports of electrical apparatus for switching or protecting circuits, not exceeding 1,000 v (nesoi) (HS 853690) totaled $572.5M in August 2026.
Importers of Electrical Apparatus for Switching or Protecting Circuits, Not Exceeding 1,000 V (NESOI) paid $49.0M in duties in August 2026, an effective tariff rate of 14.17% of the $346.0M imported — duty actually collected as a share of that value, not the published tariff schedule. Electrical Apparatus for Switching or Protecting Circuits, Not Exceeding 1,000 V (NESOI) imports of $346.0M in August 2026 ran 10% above the year-to-date monthly average of $313.9M.
Last updated: August 2026 dataTerminals, electrical splices, junction boxes, distribution ducts, battery clamps for motor vehicles, and other circuit-protection apparatus not elsewhere classified under heading 8536 all fall within this residual category for sub-1,000 V applications. The US schedule breaks this heading into eight 10-digit lines, distinguishing battery clamps for motor vehicles (8536906000) from distribution ducts, junction boxes, and general switching/protection apparatus — each with separate tariff treatment. Mexico leads import supply, followed by China and Germany, with German-origin goods often representing engineered industrial-grade components for automation and power distribution. Chinese-origin goods in this heading are subject to Section 301 tariffs, and the breadth of the NESOI basket makes precise product description on entry documentation especially important.

Junction boxes that function primarily as enclosures for making or protecting electrical connections at or below 1,000 V classify under 8536908030 or 8536908530 depending on applicable tariff treatment. However, if the box contains no switching or protective apparatus and serves purely as a structural enclosure, it may instead classify under heading 8538 or even a metal enclosure heading. The presence or absence of integrated electrical components is the key distinction.
The tariff line 8536906000 covers battery clamps specifically for motor vehicles of headings 8702, 8703, 8704, and 8711 — encompassing buses, passenger cars, trucks, and motorcycles. Clamps not meeting that vehicle-type scope would fall into the NESOI lines. Importers should confirm the vehicle heading applicable to the intended end-use to ensure correct line selection.
