Steel Imports Drop 30% Year-to-Date as Section 232 Tariffs Drive Buyers to Domestic Supply
According to Construction Dive, US steel imports fell roughly 30% on a year-to-date basis through April 2026, as Section 232 tariffs continue to disrupt trade flows and push buyers toward domestic supply.
Market Impact
April import volumes ticked up nearly 6% from March, reaching 1.87 million net tons, including 1.38 million net tons of finished steel. Driven by increased shipments of tin plate, metallic coatings, and reinforcing bars, the month-over-month uptick did little to offset the broader decline. From January through April, total imports reached 6.97 million net tons, compared to 9.89 million net tons during the same period a year ago, according to Census Bureau data compiled by the American Iron and Steel Institute (AISI).
The top supplier countries in April were South Korea, Canada, Brazil, Mexico, and Vietnam. Brandon Farris, executive vice president of the Steel Manufacturers Association, called the import decline a sign the tariffs are “working as intended,” adding that domestic steel production has increased by nearly 5 million tons since the start of 2025. AISI preliminary data shows US manufacturers processed 38.93 million net tons of raw steel from January through May 30, up 6.8% from the same period a year ago.
Morningstar analyst Seth Goldstein flagged an additional factor: disruptions from the Iran war are forcing companies to absorb extra costs, including fuel surcharges, and altering sourcing strategies. Goldstein noted that some importers may delay purchases, waiting for supply chains to stabilize rather than “buying inventory during what might be uptake pricing for the year.”
What It Means for Subcontractors
- Structural and heavy civil subs should expect tighter domestic steel availability as demand shifts away from imports. Higher competition for domestic supply can push lead times out and drive up material costs through summer.
- Pipeline and rebar-intensive contractors should note that reinforcing bar imports specifically increased in April, but the year-to-date shortfall means domestic rebar suppliers are under pressure to fill gaps. Lock in pricing and quantities early where possible.
- Budget and bid carefully. The combination of tariff-driven price floors and Iran-war-related supply chain disruptions means material cost volatility is likely to persist. Build contingency into bids and consider escalation clauses on longer-duration contracts.
- Watch for further tariff adjustments. President Trump recently signed a proclamation reducing Section 232 tariffs on agricultural and industrial equipment from 25% to 15%, and created a pathway for a 10% tariff rate on products primarily made of US steel or aluminum. Further adjustments could shift the competitive landscape quickly.
