Automatic Circuit Breakers, Voltage Exceeding 1,000 V but Less Than 72.5 kV

$55.1MU.S. imports · April 2026HS 853521

U.S. imports of automatic circuit breakers, voltage exceeding 1,000 v but less than 72.5 kv (HS 853521) totaled $55.1M in April 2026, traded with 19 countries.

Importers of Automatic Circuit Breakers, Voltage Exceeding 1,000 V but Less Than 72.5 kV paid $1.6M in duties in April 2026 — an effective duty rate of 12% on $13.0M in dutiable value, based on actual customs collections rather than the published tariff schedule.

Last updated: April 2026 data

Medium-voltage automatic circuit breakers in the 1 kV–72.5 kV range are critical protection and switching devices for utility substations, industrial power distribution, and renewable energy interconnection projects, where grid modernization and electrification investment are driving sustained demand. The entire heading resolves to a single 10-digit line (8535210000), so classification disputes typically involve distinguishing these from low-voltage breakers (below 1,000 V, heading 8536) or high-voltage breakers at or above 72.5 kV (heading 853529). Mexico and Canada are the leading US import sources — both USMCA partners — with South Korea, Italy, and Germany supplying specialized high-specification types.

Frequently Asked Questions

How do importers distinguish a medium-voltage circuit breaker (853521) from a high-voltage breaker classified elsewhere in heading 8535?

The voltage rating boundary is determinative: 853521 covers breakers rated above 1,000 V but strictly below 72.5 kV. Breakers rated at 72.5 kV or above fall under heading 853529. The manufacturer's nameplate voltage rating and the applicable IEC or ANSI standard designation (e.g., IEC 62271-100 for high-voltage AC breakers) are the primary classification evidence.

Do medium-voltage circuit breakers from Mexico and Canada benefit from preferential duty treatment?

Goods originating in Mexico or Canada that meet USMCA rules of origin are eligible for preferential tariff treatment under that agreement. Importers must obtain a valid USMCA certification of origin and ensure the product satisfies the applicable tariff-shift or regional-value-content requirement for heading 8535 before claiming the preference.
