As of mid-2025, all imported biological deodorization treatment systems are subject to a universal 10 percent tariff on their customs declarations, reinforcing a ‘level playing field’ for domestic and foreign manufacturers while aiming to stimulate local production and innovation on U.S. soil. This measure, introduced on April 5, 2025, applies broadly under Most-Favored-Nation provisions and is paused until July 9, 2025, pending further review. The elimination of de minimis rules for imports from China and Hong Kong, effective May 2, 2025, ensures that even low-value shipments are assessed for these duties, increasing the cost burden for smaller consignments.

In addition to the universal duty, critical raw materials such as steel and aluminum used in equipment frames and structural components face 25 percent tariffs under Section 232. China-origin systems incur an additional 20 percent ‘fentanyl’ tariff coupled with 25 percent Section 301 duties, cumulatively bringing total duties on Chinese imports as high as 55 percent (or up to 70 percent for steel-dominant products). These layered policies have reshaped procurement strategies, compelling end users to reevaluate their global supplier networks and consider onshore assembly to mitigate landed cost increases.

Looking ahead, proposed eco-tariff legislation under the Foreign Pollution Fee Act of 2025 could introduce import levies based on the carbon and pollution intensity of manufacturing processes in exporting countries. If enacted, such fees would further influence buyer preferences by factoring in lifecycle environmental impacts, potentially advantaging equipment producers that employ lower-emission production methods. Taken together, the cumulative impact of these tariff regimes underscores the need for proactive supply chain optimization and strategic sourcing in the biological deodorization equipment sector.
