Trump launches trade war against NATO after European countries sent troops to Greenland amid his takeover plan - Fortune

President Trump has reportedly initiated a trade war against countries that are members of the North Atlantic Treaty Organization (NATO). This significant development was reported on January 17, 2026. The action is said to be a direct response to European NATO members deploying troops to Greenland, a move that occurred amidst President Trump's stated plans for the territory.

This new trade posture has the potential to impact businesses engaged in importing goods from, or exporting to, any of the NATO member states. While specific countries targeted within the alliance, or the precise scope and nature of the trade measures, have not yet been detailed, importers should be aware that a broad range of European and North American economies could see their trade relations with the U.S. altered. Businesses with supply chain dependencies on these nations should begin to assess their exposure.

As of the reporting date, January 17, 2026, specific details regarding the trade measures—such as new tariff rates, import quotas, or other restrictions—have not been released. The source material does not specify which Harmonized Tariff Schedule (HTS) codes, product categories, or industries will be targeted, nor does it provide effective dates for any new duties or regulations. Without these specifics, it is currently impossible to quantify the direct financial impact on particular goods or supply chains.

Given the current lack of specific details, importers and trade compliance professionals are advised to remain highly vigilant. It is crucial to closely monitor official announcements from the U.S. government, including the Office of the United States Trade Representative (USTR) and U.S. Customs and Border Protection (CBP), for any forthcoming regulations or proclamations. Businesses should review their supply chains for any dependencies on NATO member countries and prepare to assess potential alternative sourcing or mitigation strategies. Consulting with legal counsel or trade compliance experts will be essential once more specific information becomes available to understand the implications for your specific operations.
