Since the original imposition of 25% tariffs on imported steel and 10% tariffs on aluminum under Section 232, U.S. policymakers have progressively expanded duties to bolster domestic production and address perceived national security concerns. As of June 4, 2025, tariffs on steel and aluminum imports have been raised to 50%, with select exceptions maintained only for the United Kingdom under the U.S.-UK Economic Prosperity Deal. These measures have directly influenced the cost structures of steel-based canister production, which traditionally relies on high-integrity stainless steel and ductile iron components.

According to United States International Trade Commission analyses, the initial 25% steel tariffs contributed to a 22.7% rise in covered steel import prices and a 0.7% increase in domestic steel prices from 2018 through 2021, while aluminum import prices climbed by 8.0%. Doubling these tariffs has intensified input cost pressures, leading manufacturers to reevaluate sourcing strategies, accelerate qualification of domestic mill suppliers, and investigate alternative materials such as cast-in-place concrete liners and high-strength ductile iron composites.

The cumulative effect has been a recalibration of supply chain timelines and contractual frameworks, with producers negotiating longer lead times to secure raw materials and passing incremental costs downstream. Project developers have responded by exploring vertically integrated supply models and strategic partnerships, aiming to mitigate volatility and ensure continuity of canister deliveries amid an increasingly protectionist trade environment.

A nuanced understanding of market segmentation reveals how distinct end users drive demand and inform product customization. Interim storage facilities, with mandates for multi-decade containment, are prioritizing canisters engineered for extended heat dissipation and retrievability, whereas nuclear power plants focus on high-throughput casks designed to support in-pool transfers and seamless integration into existing reactor infrastructure. Reprocessing facilities demand specialized canisters that facilitate handling of mixed oxide fuels, and research reactors necessitate solutions for smaller‐scale, diverse fuel assemblies.

Application-based distinctions further refine commercialization strategies. Dry storage systems, favored for their passive cooling capabilities, compete with wet storage pools for short‐term containment, while permanent disposal designs emphasize geological resilience and compatibility with deep‐underground repository conditions. Transportation requirements vary markedly between rail- and road-compatible casks, and multi-modal sea transport solutions must satisfy international shipping regulations and port handling constraints.

Material type selection adds another layer of complexity. Cast in place concrete modules offer cost advantages for on-site fabrication, while precast concrete liners deliver uniform quality control. High-strength ductile iron formulations address load-bearing needs and structural stability, whereas standard grade variants are leveraged for lower-pressure applications. Austenitic stainless steel is prized for its corrosion resistance, and ferritic stainless grades balance toughness with thermal conductivity. Capacity segmentation from low to high tonnage underpins design choices, whether for compact vertical canisters or high-capacity horizontal arrays.

The Americas have emerged as a critical hub for interim storage development, driven by U.S. federal initiatives to authorize consolidated facilities and by Mexico and Brazil’s investments to expand research reactor capacities.
