The U.S. metal packaging sector faces sustained cost pressures in 2026, with the Midwest Premium for aluminum surpassing $1 per pound for the first time in history and Section 232 tariffs on tinplate steel maintaining their grip on raw material costs.
On February 20, 2026, the U.S. Supreme Court invalidated broad tariffs imposed under the International Emergency Economic Powers Act (IEEPA). However, this ruling did not affect the primary Section 232 tariffs on metal packaging inputs, including tinplate steel and aluminum. Additionally, the Trump administration's subsequent 10% "global tariff" has not been stacked on top of the existing 50% duties under Section 232, leaving the core tariff structure intact.
"We expect greater price increases in 2026 than we saw last year," said Scott Breen, President of the Can Manufacturers Institute (CMI), at the end of January. "The Midwest Premium is sky-high, and our industry is feeling the squeeze."
Critical Dependency on Imports Creates Structural Vulnerability
Despite the tariff regime originally intended to boost domestic production, U.S. tinplate steel capacity has declined by roughly two-thirds since 2018. Today, only two domestic producers remain, capable of supplying just 30% of U.S. market demand.
This supply gap forces American can manufacturers to import nearly 80% of their tinplate steel requirements, up from approximately 42% just six years ago. Consequently, U.S. tin mill product prices now rank 20% to 30% higher than European benchmarks, placing domestic manufacturers at a significant competitive disadvantage.
Key Statistics:
Import dependency: ~80% of tinplate steel (2026)
Domestic capacity utilization: Down 66% from 2018 levels
Active U.S. tinplate production lines: 3 (down from 12 eight years ago)
Cost impact on manufacturers: Up to 12% increase in total production costs
Tariff Relief Advocacy Intensifies
The Can Manufacturers Institute continues active engagement with the Trump administration, seeking targeted tariff relief to ensure competitive access to essential raw materials.
"We're talking with the Trump administration, explaining this reality for our industry, because we're domestic manufacturers too—we support thousands of jobs across this country," Breen emphasized. "We don't want our industry to be threatened. We need to make sure that we have the tinplate steel we need at a competitive price to make the cans."
CMI's advocacy centers on a narrow, common-sense adjustment that would:
Lower food costs for American consumers
Limit foreign imports of finished canned foods
Provide relief to U.S. farmers and food producers
Protect manufacturing jobs in American can and food processing plants
The organization argues that tinplate steel—representing less than 1% of global steel production—is a specialized product that requires distinct policy treatment from high-volume steel categories like rebar and flat-rolled steel.
Downstream Impact on Consumer Prices
Research from the University of Cincinnati indicates that canned foods experienced some of the sharpest price increases among grocery categories at the end of 2025. U.S. Bureau of Labor Statistics data shows canned fruit and vegetable prices have risen more than 31% since 2020.
Industry analysts warn that without tariff adjustments, these inflationary pressures will intensify throughout 2026. The American Action Forum estimates that maintaining the 50% tariff could increase costs for can manufacturers by approximately 12%, with downstream effects rippling through grocery supply chains.
"Consumers, manufacturers, and CMI members need the Trump administration to act quickly to provide tariff relief to lower food costs and bolster national food security," said Pearce Crosland, Senior Director of Government Relations at CMI.
Geopolitical Uncertainty Adds Complexity
The renewed conflict in Iran and broader Middle East instability introduces additional volatility into aluminum markets. The region accounted for 21% of U.S. unwrought aluminum imports and 13% of wrought aluminum imports in 2025, making supply chain disruptions a growing concern.
The Aluminum Association confirmed this week that it remains in "close contact with member companies" regarding potential supply implications.
Industry Outlook
While canmakers maintain that canned goods remain an affordable and attractive offering for consumers despite price increases, CMI acknowledges uncertainty about whether consumer purchasing patterns will hold steady under sustained cost pressures.
The U.S. Trade Representative's 2026 trade policy agenda, released this week, signals continued commitment to an "America First" approach, including review of the U.S.-Mexico-Canada Agreement (USMCA)—which currently exempts many North American traded products from new tariffs.
About the Can Manufacturers Institute (CMI)
CMI is the national trade association of the U.S. metal can manufacturing industry and its suppliers, representing more than 28,000 employees and generating approximately $15.7 billion in direct economic activity annually. The industry produces roughly 130.7 billion food, beverage, and general line cans each year.
