Since 2018, United States trade policy has imposed a series of tariffs that have cumulatively reshaped the fixed air circuit breaker supply chain, prompting manufacturers to accelerate local production and diversify sourcing strategies. Section 232 tariffs reinstated in March 2025 have raised steel and aluminum duties to 25 percent, expanded derivative product coverage to include circuit breaker components, and eliminated prior country exemptions, substantially increasing raw material costs for switchgear assembly. The June 3 2025 proclamation further intensified these measures by doubling the steel and aluminum tariffs to 50 percent on specified goods, deepening the impact on imported switchgear and downstream industries reliant on these metals.

Concurrently, Section 301 actions have maintained 25 percent tariffs on Chinese-origin electrical apparatus, including switchgear classified under HTS Chapter 85, with partial coverage of transformer components and related machinery. These duties, effective January 1 2025, have sustained elevated import prices and driven multinational companies like ABB to invest over USD 120 million in domestic production facilities across Tennessee and Mississippi, achieving approximately 75 to 80 percent U.S. content in their sales portfolio to mitigate future tariff volatility. Similar moves by Siemens and other key players have underscored a broader realignment toward near-shore manufacturing.

Analyses from the U.S. International Trade Commission indicate that downstream sectors experienced an aggregate annual production drop valued at USD 3.4 billion between 2018 and 2021, as higher steel prices from Section 232 tariffs translated into a 0.6 percent reduction in output for industries consuming significant quantities of metal inputs. The construction and automotive segments, accounting for nearly three-quarters of steel consumption, were notably impacted. These cumulative tariff measures have compelled circuit breaker vendors to optimize supply chains, pursue tariff exclusion requests under announced processes for machinery classified in HTS Chapters 84 and 85, and reevaluate product portfolios to sustain competitiveness in the U.S. market.
