U.S. imports of isolating switches and make-and-break switches, over 1,000 v (HS 853530) totaled $38.1M in April 2026, traded with 30 countries.
Importers of Isolating Switches and Make-and-Break Switches, Over 1,000 V paid $1.8M in duties in April 2026 — an effective duty rate of 11% on $16.8M in dutiable value, based on actual customs collections rather than the published tariff schedule. Isolating Switches and Make-and-Break Switches, Over 1,000 V imports of $38.1M in April 2026 ran 11% below the year-to-date monthly average of $42.9M.
Last updated: April 2026 dataIsolating switches and make-and-break switches for voltages exceeding 1,000 V serve as de-energization and sectionalizing devices in medium- and high-voltage distribution and transmission systems. The US schedule separates knife-type switches (8535300040) from all other types (8535300080), a construction-based distinction that reflects different contact mechanisms and application environments. Mexico and Canada together account for a substantial share of US imports under this heading, with Norway and Italy also notable sources — an unusual supplier mix that reflects both nearshore manufacturing and European specialty producers. Knife-type switches, in particular, are a common point of classification dispute given their overlap with disconnect switches used in utility applications.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Knife-type switches use a blade-and-jaw contact mechanism that physically opens the circuit by withdrawing a conductive blade. Under the US tariff schedule, this construction places them in 8535300040, separate from other isolating and make-and-break switch designs classified under 8535300080. The distinction turns on the contact mechanism, not the voltage rating alone.
Norway hosts specialized manufacturers of high-voltage switchgear and disconnect equipment serving utility and industrial markets globally. Its presence in the US import mix alongside Mexico and Canada reflects the niche, engineering-intensive nature of this product category, where European producers with long utility-sector relationships maintain competitive positions even against lower-cost manufacturing regions.
