U.S. imports of fuses for electrical apparatus, voltage exceeding 1,000 v (HS 853510) totaled $22.5M in July 2026, traded with 38 countries.
Importers of Fuses for Electrical Apparatus, Voltage Exceeding 1,000 V paid $1.2M in duties in July 2026 — an effective duty rate of 18% on $6.9M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataHigh-voltage fuses rated above 1,000 V protect medium-voltage distribution equipment, industrial switchgear, and utility infrastructure from fault currents, and their design must meet stringent interrupting-capacity and voltage-withstand standards. The US schedule divides this heading between fuses for circuits at or above 2,300 V (8535100020) and those for voltages above 1,000 V but below 2,300 V (8535100040) — a distinction that reflects different utility distribution voltage classes in North America. Mexico leads US import supply, followed by the Dominican Republic, both reflecting assembly operations by multinational electrical equipment manufacturers in the Caribbean Basin region.

The 2,300 V threshold corresponds to a historically common North American distribution voltage class (2.4 kV systems), allowing trade statistics to distinguish fuses used in lower medium-voltage networks from those used in higher-voltage transmission and distribution applications. This granularity matters for infrastructure procurement tracking and trade-remedy analysis.
Customs entry itself does not require product safety certification, but buyers and importers should be aware that high-voltage fuses sold in the US market are typically required to meet ANSI/IEEE standards (such as IEEE C37.40 series) or UL listings depending on the application. These are market-access requirements enforced by utilities and end-users rather than CBP admissibility conditions, but having test reports available can expedite commercial acceptance.
