Presidential Proclamation’s Pivotal Pivot

The White House released a proclamation on Thursday, 2 April 2026, fundamentally reshaping how the United States applies Section 232 tariffs to derivative products. President Donald Trump signed an executive order altering the valuation method for imported goods substantially made of steel, aluminium or copper. Previously, customs authorities collected 50% tariffs only on the metal component’s value, a system that allowed importers to minimise tax liabilities through creative accounting. The new rule imposes a flat 25% duty on the full value of derivative articles, meaning a finished product like a steel pipe or aluminium chassis now pays tariffs based on its entire price, not just its raw material content. For commodity-grade steel and aluminium, the existing 50% tariff remains unchanged. Articles made entirely or almost entirely of these metals, such as steel coils and aluminium sheet, will pay a flat 50% on their full value. Kevin Dempsey, president and chief executive officer of the American Iron and Steel Institute (AISI), applauded the decisive action. “AISI commends the decisive action taken today by President Trump to ensure that all steel mill products, including steel pipe and tube, receive the full benefit of the 50% tariffs on steel products,” Dempsey stated on Thursday. He added that his organisation welcomes steps to simplify applying steel tariffs to critical steel derivative products. The proclamation also introduces lower tariffs for products made abroad using entirely American metals, which will face only 10% duties, while products containing 15% or less steel, aluminium or copper become exempt from Section 232 tariffs entirely.

Derivative Definitions Drive Dramatic Differences

Market sources immediately began speculating about the impact on import prices. The previous method taxed only the metal component, a loophole that Century Aluminum described as systematic abuse. “Importers had been abusing valuation loopholes to reduce their liability under the President’s steel and aluminum tariffs,” the company said in a statement on Thursday. “In some instances, importers declared only the value of raw steel and aluminium while excluding value added through processing, thereby lowering the tariff owed and disadvantaging domestic manufacturers.” The new proclamation closes this gap by requiring importers to declare the full value of covered products. Certain metal-intensive industrial equipment and electrical grid equipment will pay 15% duties through 2027, a measure designed to accelerate the massive industrial base buildout currently underway across the United States. Phil Bell, president of the Steel Manufacturers Association (SMA), highlighted the importance of expanding metals tariffs to include derivative products. “Last year, the Commerce Department’s introduction of a steel derivatives inclusion process responded to urgent concerns from downstream manufacturers,” Bell said on Thursday. “While domestic raw steel production increased under strengthened tariffs, many steel-containing goods continued to be dumped into the US market, placing significant strain on American manufacturers. The robust derivatives process helped close these gaps, strengthening supply chains & supporting US manufacturing.”

Domestic Producers’ Decidedly Delighted Disposition

American steel & aluminium producers welcomed the overhaul unanimously. Century Aluminum CEO Jesse Gary articulated the transformative effect of Section 232 tariffs on domestic production. “With the 50% Section 232 tariffs on primary aluminum still fully in force with no exemptions or exceptions, today’s executive order reinforces that foreign actors will no longer be allowed to game the system at the expense of Americans,” Gary said on Thursday. He provided concrete evidence of policy success: “Century Aluminum is proof that President Trump’s policies are working. Since President Trump reinforced Section 232 last year, with no exemptions or exceptions, we have expanded US aluminum production by 10% and committed billions to new capacity that will double US production and create thousands of new American jobs.” The AISI’s Dempsey emphasised long-term durability concerns. “These measures will ensure that the steel tariff program operates effectively and efficiently and will ensure the long-term durability of the Section 232 tariffs, which remain essential to address the adverse impacts of global steel excess capacity that continues to grow due to foreign subsidies and other trade-distorting practices,” Dempsey continued. The SMA’s Bell reinforced that right-sizing the derivatives list and updating the valuation of steel-containing goods supports the revitalisation of the American steel industry without undermining broader economic goals.

Loophole Liquidation Levels Lingering Leverage

The valuation loophole proved particularly pernicious for domestic manufacturers competing against imported derivative products. Importers could purchase semi-finished steel or aluminium from foreign mills, ship these materials to a third country for minimal processing such as cutting, bending or coating, then declare only the raw metal value when entering the United States. This practice effectively reduced tariff payments by 50% or more, undermining the protective intent of Section 232. Century Aluminum’s statement explicitly called out this abuse: “In some instances, importers declared only the value of raw steel and aluminium while excluding value added through processing.” The new proclamation eliminates this strategy by mandating full value declaration for covered products. Products made abroad but entirely with American steel, aluminium & copper receive preferential treatment at 10% tariffs, creating a strong incentive for foreign manufacturers to source US metals. Products containing 15% or less steel, aluminium or copper escape Section 232 tariffs entirely, a de minimis threshold that exempts many consumer goods like electronics or small appliances from trade restrictions. The 15% duty on certain metal-intensive industrial & electrical grid equipment through 2027 provides a transitional period, allowing domestic capacity expansion before full tariff application.

Global Glut’s Gradual, Grinding Grip

Global steel overcapacity remains the underlying justification for these trade measures. China alone produces more steel than the rest of the world combined, much of it subsidised by state owned enterprises operating below cost. This excess production floods international markets, depressing prices and making it nearly impossible for unsubsidised producers in the United States and Europe to compete. The Section 232 programme, originally enacted during President Trump’s first term, aims to protect domestic metal production as a matter of national security. Without a robust domestic steel & aluminium industry, the United States would depend on foreign sources for military shipbuilding, pipeline construction, electrical grid components, and countless other strategic applications. Kevin Dempsey of AISI explicitly linked the tariff overhaul to global excess capacity “that continues to grow due to foreign subsidies and other trade-distorting practices.” The new derivative product rules extend the protective umbrella further down the supply chain, ensuring that foreign finished goods cannot evade tariffs simply by incorporating small amounts of US sourced metal or by performing minimal processing outside American borders. This approach mirrors strategies employed by the European Union, which has implemented its own Carbon Border Adjustment Mechanism to prevent carbon leakage while protecting domestic industry.

Century’s Credible, Concrete Capacity Expansion

Century Aluminum’s response to the strengthened Section 232 regime offers a compelling case study in industrial policy success. The company reported a 10% expansion in US aluminium production since President Trump reinforced Section 232 tariffs the previous year with no exemptions or exceptions. This production increase translates to tens of thousands of additional metric tons of primary aluminium flowing from Century’s smelters into American manufacturing supply chains. The company has committed billions of dollars to new capacity that will double US production, a capital investment cycle that creates thousands of construction jobs during facility buildout plus permanent operational positions once smelters come online. Century CEO Jesse Gary positioned his company as living proof that tariff policies work. The new derivative product rules protect this expanding domestic capacity by ensuring that foreign finished goods cannot undercut American made products through tariff avoidance schemes. Without the valuation loophole closure, a foreign manufacturer could import Chinese aluminium into Mexico, fabricate it into an automotive component, then ship that component to the United States while paying tariffs only on the raw aluminium value, not the finished part’s full price. The proclamation eliminates this arbitrage opportunity, creating a level playing field for Century and other domestic metal producers.

Industrial Equipment’s Interim, Intentional Immunity

The proclamation includes a notable exception for certain metal-intensive industrial equipment and electrical grid equipment, which will face only 15% duties through 2027. This provision reflects a pragmatic recognition that the United States cannot instantly replace foreign sourced heavy machinery. Transformers, generators, turbines, and other grid components often require specialised manufacturing capabilities that domestic producers are actively developing but have not yet fully scaled. The 15% duty, lower than the 25% or 50% rates applied to other derivative products, serves two purposes. First, it raises the price of imported equipment enough to encourage domestic sourcing without crippling infrastructure projects. Second, it provides a clear timeline for tariff escalation after 2027, incentivising foreign manufacturers to establish US production facilities. This approach aligns with the broader goal of accelerating the massive industrial base buildout currently underway across the United States. Electrical grid equipment receives particularly favourable treatment because modernising America’s aging power infrastructure stands as a national priority, one that cannot afford delays caused by sudden tariff shocks. The 15% duty strikes a balance between protecting nascent domestic manufacturers and ensuring that utilities can access necessary equipment for renewable energy integration, transmission upgrades, and resilience improvements.

Simplification’s Sine Qua non for Supply Chains

The American Iron & Steel Institute emphasised simplification as a critical benefit of the new proclamation. Previous derivative product rules required complex determinations of metal content percentage and value attribution, creating administrative burdens for customs officials and importers alike. The new flat rate system based on full value declaration reduces compliance costs and enforcement ambiguity. Phil Bell of the Steel Manufacturers Association described the updated derivatives list as “right-sizing,” a term that acknowledges the dynamic nature of manufacturing. As products evolve, the list of covered derivative articles must evolve too, capturing new categories of steel and aluminium intensive goods while removing items where metal content has become negligible. The 15% or less de minimis threshold provides a clear, objective standard that eliminates disputes over borderline cases. Kevin Dempsey welcomed steps to simplify the process for applying steel tariffs to critical steel derivative products. This simplification extends to the preferential 10% tariff for products made abroad using entirely American steel, aluminium and copper. Foreign manufacturers can now calculate their tariff liability with certainty: source all metal from the United States, pay 10% on full value; source any metal from elsewhere, pay 25% or 50% depending on product category. This binary choice simplifies supply chain decisions and creates a powerful incentive for foreign companies to buy American metal.
