Tariff headlines are back in focus, with fresh Section 301 proposals, shifting steel and aluminum duties, and questions around USMCA all reshaping the cost of doing business across borders. For North American manufacturers, higher and more uncertain trade costs can either squeeze margins or create openings where competitors face bigger hurdles. This article looks at three stocks from a U.S., Canada, and Mexico manufacturing screener that appear positioned to benefit from these policy moves. It explores how their business models intersect with the latest tariff rules and where investors may want to dig deeper.

Century Aluminum (CENX)

Overview: Century Aluminum produces primary aluminum and alumina, supplying both standard and higher value products from smelters in the United States and Iceland, supported by a carbon anode plant in the Netherlands and bauxite and alumina operations in Jamaica.

Operations: The company generates all its US$2.5b of revenue from primary aluminum, with around US$1.9b coming from the United States and about US$660 million from Iceland.

Market Cap: US$5.4b

Century Aluminum sits at the heart of the tariff story, with a largely U.S. and EU production footprint that benefits when Section 232 and Section 301 measures raise costs for overseas competitors and support regional aluminum premiums. Recent trade actions limiting imports from China and other countries, together with projects like the Mt. Holly expansion and the planned Oklahoma smelter, position the company to serve reshoring and electrification demand while tapping U.S. manufacturing tax credits. At the same time, investors need to weigh meaningful risks, including sensitivity to power and raw material costs, heavy reliance on supportive trade policy, and some recent insider selling. All of these factors can affect the quality and durability of current profitability and growth expectations.

Tariff fueled momentum at Century Aluminum looks powerful, but the full story sits in how policy support, power costs and new U.S. projects interact. Start with the 4 key rewards and 2 important warning signs (1 is major!)

West Fraser Timber (TSX:WFG)

Overview: West Fraser Timber is a large Canadian wood products company that makes lumber, engineered wood panels, pulp, paper, and bioenergy inputs used in housing, renovation, packaging, and industrial applications across North America and Europe.

Operations: West Fraser Timber generates most of its US$5.3b of revenue from Lumber at US$2.5b and North America Engineered Wood Products at US$2.0b, with Europe Engineered Wood Products contributing US$524 million and the balance from segment adjustments and corporate items.

Market Cap: CA$7.8b

West Fraser Timber stands out in this screener because it sits on the right side of several trade and sustainability trends, yet still carries meaningful risks. As a Canadian exporter into the U.S., it benefits when Section 301 tariffs raise costs for overseas competitors while USMCA keeps its own trade channels relatively open, even as softwood lumber duties and tariff uncertainty remain a drag. Some analysts highlight the possibility of a shift from current losses to future profitability, supported by higher margin engineered wood products, mill modernization and a growing sustainability story including emissions targets and long term fibre agreements. At the same time, recent losses, ongoing trade disputes and a dividend that is not covered by earnings show that the recovery path is not straightforward.

West Fraser Timber’s shift from basic lumber to higher margin engineered wood and bio-products could be more than a cycle story. Yet the real twist is buried in the 2 key rewards and 1 important major warning sign

Amprius Technologies (AMPX)

Overview: Amprius Technologies develops and sells silicon anode lithium ion batteries, with its SiCore and SiMaxx product lines designed for high energy density mobility uses such as drones, high altitude aircraft and other emerging aviation platforms.

Operations: Amprius Technologies generates US$90.3m of revenue from its Battery Business, with around US$62.8m from EMEA customers, US$15.9m from North America and US$11.5m from Asia Pacific.

Market Cap: US$2.2b

Amprius Technologies sits at the intersection of tariff policy and next generation battery demand, with U.S. anchored supply chains, high energy density cells and a growing mix of defense, drone and electric mobility customers. New Section 301 tariffs that keep import costs elevated for foreign battery suppliers can affect the relative economics for Amprius, particularly as it secures multi million contracts, expands global capacity and raises 2026 revenue guidance. The flip side is real execution risk, including heavy exposure to aviation and drone demand, complex scale up of silicon anode technology, share dilution and ongoing losses that still need to narrow. For investors watching North American manufacturing, a key question is how those policy tailwinds, growth targets and balance sheet risks fit together into a coherent risk reward view on Amprius.

Amprius Technologies is racing to scale high energy batteries as tariffs reshape who wins future defense and drone contracts, but the real tension between its ambition and its risks sits inside the 3 key rewards and 3 important warning signs
