U.S. imports of electrical circuit protection apparatus, not exceeding 1,000 v (nesoi) (HS 853630) totaled $80.4M in April 2026, traded with 58 countries.
Importers of Electrical Circuit Protection Apparatus, Not Exceeding 1,000 V (NESOI) paid $8.0M in duties in April 2026 — an effective duty rate of 12% on $65.3M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataResidual low-voltage circuit protection apparatus — including motor overload protectors and other devices not classified as fuses or automatic circuit breakers — serves critical roles in motor control centers, industrial machinery, and building automation systems. Three US tariff lines cover this space: a general NESOI provision (8536300000), a dedicated motor overload protector line (8536304000), and a broader residual (8536308000). China is the leading supplier, followed by Mexico and the Philippines; Chinese-origin goods in this heading are subject to Section 301 tariff measures, and Vietnam and Czech Republic also appear among top sources, reflecting supply-chain diversification by multinational manufacturers. Correct classification between the motor overload protector line and the broader NESOI provisions is a recurring compliance issue.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Motor overload protectors rated at or below 1,000 V fall under heading 853630, specifically 8536304000. Those rated above 1,000 V are instead classified under heading 853590 (8535904000). The voltage threshold is the primary classification determinant, and importers should confirm the device's rated voltage from the manufacturer's technical documentation before filing.
Several major European electrical equipment manufacturers — particularly those producing motor protection and control devices — operate production facilities in the Czech Republic as a lower-cost EU manufacturing base. Vietnam's presence reflects broader electronics and electrical component assembly investment by multinational firms seeking to diversify away from China, particularly following Section 301 tariff exposure on Chinese-origin goods.
