U.S. imports of lightning arresters, voltage limiters, and surge suppressors, over 1,000 v (HS 853540) totaled $8.8M in July 2026, traded with 42 countries.
Importers of Lightning Arresters, Voltage Limiters, and Surge Suppressors, Over 1,000 V paid $977K in duties in July 2026 — an effective duty rate of 16% on $6.3M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataMetal-oxide and silicon-carbide surge protective devices rated above 1,000 V protect transformers, switchgear, and transmission lines from transient overvoltages caused by lightning strikes and switching events. All US imports under this heading consolidate into a single 10-digit line (8535400000), meaning classification is straightforward, but technical specification — particularly the rated voltage class and energy absorption capacity — remains critical for utility procurement and compliance with IEEE and IEC standards. Mexico is the leading supplier, with Germany and Switzerland reflecting the European engineering heritage in high-voltage surge protection technology. Goods originating in China are subject to Section 301 tariff measures, a factor importers should weigh when evaluating sourcing options.

Yes — under heading 853540, lightning arresters, voltage limiters, and surge suppressors for voltages exceeding 1,000 V all classify under the single 10-digit line 8535400000. Despite functional differences in application, the tariff schedule does not subdivide them further, so the classification decision centers on confirming the voltage threshold rather than the device's specific protective function.
Utility and industrial buyers commonly require compliance with IEEE C62.11 (for metal-oxide surge arresters) or IEC 60099 series standards. While US Customs does not mandate these certifications for entry, they are routinely referenced in purchase orders and may be required by the end-user or grid operator, making their inclusion in shipping documentation a practical best practice.
