In a recent development, President Donald Trump announced a one-month suspension of 25 per cent tariffs on Canadian and Mexican aluminium imports just days after announcing their imposition. The temporary pause, which extends until March 1, 2025, signals potential renegotiations over trade concerns and border security issues, raising uncertainty for US aluminium importers and domestic manufacturers alike.
Tariff turbulence: Domestic industry impacted
Already familiar with tariff-induced disruptions, the aluminium industry faces renewed concerns as traders and manufacturers brace for possible policy changes. Section 232 tariffs, imposed in 2018 during Trump’s first term, introduced a 10 per cent duty on aluminium imports, citing national security threats due to over-reliance on foreign metals. While these tariffs aimed to back domestic production, they ended up having mixed consequences.
Domestic manufacturers were hit with a surge in raw aluminium prices, which in turn led to increased operational costs. Many were forced to pass these expenses onto consumers or absorb the costs, tightening margins. According to Lance Thrailkill, CEO of Texas-based All Metals Fabricating, “The tariffs both directly and indirectly raised our costs. Mills in the US and abroad increased their prices as the market adjusted to the tariffs. Unfortunately, we had to pass some of these costs down to our customers.”
While some aluminium producers, including Century Aluminum and Alcoa, expanded operations due to the protective measures, smaller manufacturers and downstream industries, such as the automotive and packaging sectors, struggled with higher input costs and supply chain disruptions.
Trade statistics and cross-border concerns
US aluminium imports from Canada and Mexico have been significant contributors to the supply chain. In 2023, the United States imported approximately 3.2 million tonnes of aluminium from Canada, accounting for close to 50 per cent of total imports. Mexico supplied an additional 105,000 tonnes, with about 6 per cent of that volume originating from non-North American sources.
Au contraire to popular opinion, the Coalition for a Prosperous America (CPA) has been a vocal advocate for stricter aluminium tariffs, arguing that Mexico’s exemption from Section 232 has led to a concerning surge in imports. They have lobbied for expanded tariff coverage to include derivative products, such as aluminium wire rods and vehicle components, which are critical to US manufacturing.
CANACERO, the Mexican steel and aluminium manufacturers’ association, has pushed back against these claims, highlighting that US Census Bureau data shows the US maintains a surplus with Mexico in finished aluminium products. They argue that Mexican exports are not responsible for domestic plant closures or job losses.
China’s role and tariff implications
China, a key player in the global aluminium market, has long been a target of US trade restrictions. Under the 2018 Section 232 tariffs, a 10 per cent duty was imposed on all aluminium imports from China, aimed at countering the country’s alleged dumping practices and state subsidies that distorted global prices. Despite these tariffs, Chinese aluminium products have found indirect routes into the US market, often through transhipment points in Mexico and other countries.
In a recent move, the Trump administration has again imposed a 10 per cent tariff on all aluminium imports from China starting February 1, 2025. The decision was declared to be a part of efforts to counter what officials describe as China’s market-distorting practices, including state subsidies and aluminium dumping that have impacted global pricing. The new tariffs aim to reduce dependency on Chinese aluminium and encourage greater investment in domestic production. However, traders and manufacturers have expressed concerns over potential supply chain disruptions and rising costs. With China accounting for approximately 60 per cent of global aluminium production, the tariff escalation is likely to influence pricing dynamics and further strain trade relations. Some experts warn that China’s products may continue to enter the US market through transhipment points, particularly Mexico, underscoring the need for vigilant enforcement of trade policies.
What lies ahead for US aluminium traders
The Trump administration has tasked federal agencies with reviewing Section 232 tariffs, with recommendations due by April 1, 2025. Industry stakeholders anticipate an intense lobbying period due to the tight deadline and expected inter-agency debates. Aluminium traders are particularly concerned about the potential reimposition or modification of tariffs, which could further destabilise pricing and supply chains.
Analysts suggest that the uncertainty surrounding tariff policy could have a chilling effect on investment and procurement decisions. “Even the possibility of tariffs returning forces traders to stockpile inventory or delay orders, disrupting market dynamics,” noted a trade economist from Georgetown University.
As negotiations unfold, domestic aluminium buyers and manufacturers are urging the administration to consider the broader economic implications of tariff decisions. The balancing act between protecting US producers and maintaining competitive input costs for downstream industries remains a complex challenge—one with significant ramifications for the US manufacturing landscape.
