We must protect our country and our workers. Our steel industry is in bad shape. IF YOU DON'T HAVE STEEL, YOU DON'T HAVE A COUNTRY!
Watch Trump signs the steel tariffs in 2018
How They Responded: "Trump Is Wrong"

USA TODAYThe Evidence: Positive Trends Emerged
Trump signed the Section 232 steel and aluminum tariffs in March 2018. The economists said it would gut American manufacturing. Here is what the data shows happened to the domestic steel industry.
Domestic Steel Capacity Was Restored
- Capacity utilization jumped from the low-70s to the 80s. Pre-tariff capacity utilization in the U.S. steel industry averaged around 74%. After the tariffs, it climbed into the 80% range and reached 81.1% in mid-2021, the highest level since 2007.
- The industry rebuilt domestic production. Maintaining utilization above the 80% target rate that the Commerce Department identified as necessary for a viable domestic steel base was the explicit goal of the policy, and the policy hit it.
The Strategic Vulnerability He Warned About Was Real
- The pandemic proved the national-security case. The domestic steel base held through the COVID collapse, utilization fell to 51.1% in April 2020 and recovered to stronger-than-pre-tariff levels, exactly as global supply chains seized up and exposed the danger of depending on foreign production for critical materials.
- The industry reinvested at home. Tariff protection drove roughly $13 billion in new U.S. steelmaking and mill investment, even as domestic steel prices fell back after the initial spike.

U.S. Department of Commerce: Section 232 Investigation on the Effect of Imports of Steel on National Security
"The quotas or tariffs imposed should be sufficient... to enable U.S. steel producers to operate at an 80 percent or better average capacity utilization rate based on available capacity in 2017."

"In other nations, policy makers recognize that making things matters and aggressively tilt their own markets to attract investment and production, including with tariffs. Not by coincidence, and not because of some naturally occurring "comparative advantage," vital industrial functions like the production of semiconductors, rare-earth minerals and pharmaceuticals, all pioneered in the U.S., are now dominated by overseas operations."

Wall Street JournalWhat Has Surfaced Since Trump Returned
Since returning to office in January 2025, the administration has moved from defending the original tariffs to expanding them, and domestic producers have responded with investment. The record since is documented in official actions.
Section 232 steel and aluminum tariffs raised to 50 percent (June 2025)
The administration doubled the Section 232 tariff on imported steel and aluminum from 25 percent to 50 percent, citing the need to protect domestic capacity as a matter of national security.

A partnership between Nippon Steel and U.S. Steel was structured around a roughly $14 billion investment in American steelmaking, including new and upgraded facilities, keeping U.S. Steel headquartered in Pittsburgh.

The administration continued to strengthen and broaden the metals tariff regime, extending Section 232 protections and adjusting rates to keep pressure on import surges undercutting domestic producers.

Donald Trump's 2018 Section 232 tariffs on steel and aluminum drew immediate, near-unanimous condemnation from economists, manufacturers, and trading partners, who predicted job losses and trade wars. The record since validates the core premise behind his push for domestic steel production.
Key points supporting the view that Trump's concerns were valid:
- Increased Domestic Capacity Utilization: Data from AISI showed a notable increase in steel capacity utilization rates following the tariffs, indicating the domestic industry operated more fully.
- Sector Employment Stability: Contrary to fears of mass layoffs offsetting gains, BLS data showed relative stability and even periods of growth in direct steel industry employment post-tariffs.
- Strategic Importance Highlighted: Subsequent global events, particularly supply chain disruptions during the pandemic, underscored the strategic vulnerability Trump had warned about, lending weight to the national security argument for stronger domestic production.
Trump said it plainly in 2018: "If we don't have steel, we don't have a country." The establishment called it economically illiterate. Then capacity utilization climbed back above 80% for the first time since 2007, the industry reinvested $13 billion at home, and a global supply-chain crisis proved exactly why a nation cannot outsource its steel. He was right.
