The October 22 proclamation follows a US national-security investigation and requires trade officials to report on negotiations with foreign partners within 180 days.
US President Donald Trump signed a proclamation on October 22, 2026 directing the commerce secretary and US trade representative to pursue or continue negotiations with foreign partners over imports of wind turbines and their parts. The action imposes no new tariffs and changes no existing ones.
Some wind-turbine components already face tariffs under earlier measures covering aluminum, steel and copper. The proclamation expressly preserves those duties and all other existing Section 232 tariffs, so importers face a negotiation process rather than a new tariff increase under this action.
The decision follows a Commerce Department investigation under Section 232 of the Trade Expansion Act of 1962, which authorizes presidential action on imports deemed to threaten national security. Trump endorsed the commerce secretary’s finding that wind-turbine imports threaten to impair US national security.
According to the proclamation, the secretary found that imported wind-energy equipment could contain cybersecurity vulnerabilities allowing remote control of turbines and disruption of electricity generation. The secretary singled out networked inverters, equipment that converts electricity generated by turbines into a form usable by the grid or local systems.
The secretary also concluded that wind power’s variable output burdens the electricity grid and diverts resources from energy sources he considers more reliable. The proclamation attributes to him concerns about turbines interfering with radar used for aviation, weather forecasting and defense, and a finding that US wind energy relies on imported components.

The commerce secretary must continue monitoring wind-turbine imports and advise Trump of circumstances that might warrant further action. Trump says he may consider alternative measures depending on the negotiations' status or outcome.
The proclamation describes authority for further import measures if an agreement is not reached within 180 days, is not implemented or proves ineffective. It does not make tariffs automatic at that point. The next required step is at least one update from the commerce secretary and trade representative to Trump within 180 days of October 22.
