Recent Executive Orders have addressed the challenge of overlapping duty rates, instructing agencies to prevent “stacking” of tariffs for certain product categories. However, this directive specifically targets automobiles, steel, aluminum, and related sectors, leaving key chemical imports subject to multiple tariff regimes without relief from cumulative duties. At the same time, a wide array of major chemicals-including polymers such as polyethylene and polypropylene-were explicitly excluded from the new tariff list announced in April 2025, though this exemption did not extend to water treatment specialty chemicals, which continue to face duties under broader trade actions.

Under the Section 301 tariff lists, ion-exchangers based on polymers and activated carbon-critical adsorbents in water purification-are subject to a 25% duty, directly inflating the cost of imported filtration media and catalyst supports. These levies apply to products classified under HTS codes for primary forms of ion-exchange resins and activated carbon, increasing input costs for end users and equipment manufacturers alike. In practice, this has driven water treatment firms to reassess global sourcing strategies, stockpile key reagents at pre-tariff prices when possible, or pivot toward domestic and alternative regional suppliers to mitigate exposure.

The ripple effects extend beyond direct chemical costs. Tariffs on steel, aluminum, and component imports raise the price of treatment equipment such as clarifiers, dosing systems, and membrane modules, compounding operating expenses for utilities and industrial processors. Many organizations are absorbing these increases through tighter margin management, while others are negotiating long-term contracts or seeking pass-through mechanisms in their service agreements. Regulatory lags in rate-setting for public utilities can defer the impact on end users, but in the medium term, the increased cost burden may lead to higher water tariffs or capital allocation shifts away from modernization projects. Overall, the cumulative tariff environment of 2025 is reshaping supply chains, cost structures, and investment priorities across the water treatment chemicals ecosystem.
