Anticipated tariff dynamics in 2025 shaping sourcing strategies, manufacturing footprint decisions, and pricing negotiations across the fusion proteins value chain

Anticipated tariff adjustments in the United States for 2025 are expected to have material implications for fusion protein development and commercialization, with cascading effects across procurement, manufacturing location decisions, and pricing strategy. Increased duties on raw materials, disposable bioprocess components, and laboratory equipment can raise the landed cost of goods for developers that rely on international suppliers. As a consequence, many organizations will need to reassess supplier contracts, scrutinize total landed costs, and explore nearshoring or regional sourcing to mitigate exposure to import tariffs.

Beyond direct procurement impacts, tariffs can influence strategic decisions regarding where to site biomanufacturing capacity. Higher import costs may incentivize investment in domestic or regional manufacturing hubs, accelerating conversations around capital allocation for new facilities or expanded capacity with local contract manufacturers. However, transitioning production footprint is neither instantaneous nor costless; lead times, regulatory transfers, and validation activities introduce complexity that companies must plan for proactively.

In parallel, tariffs can exert indirect pressure on pricing and reimbursement discussions. Payers and health systems under cost containment pressures may require clearer evidence of economic value, particularly if list prices need to adjust to offset higher production costs. To manage this dynamic, developers should enhance supply chain transparency, build scenario models that account for tariff-driven cost variability, and engage early with procurement stakeholders to communicate cost drivers and potential mitigations. In sum, the tariff environment in 2025 will likely compel a strategic rebalancing across sourcing, manufacturing, and pricing policies to preserve both access and margins.
