U.S. imports of Isolating Switches and Make-and-Break Switches, Over 1,000 V (HS 853530) totaled $51.4M in August 2026, imported from 36 countries.
Importers of Isolating Switches and Make-and-Break Switches, Over 1,000 V paid $4.8M in duties in August 2026, an average duty rate of 9.34% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Isolating Switches and Make-and-Break Switches, Over 1,000 V imports of $51.4M in August 2026 ran 16% above the year-to-date monthly average of $44.2M.
Last updated: August 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.

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.
