Steel and Aluminum Imports in the U.S.

Import tariffs imposed on certain steel and aluminium products from 23 March 2018

On 8 March 2018 the USA announced that, for national security reasons, it was introducing new import tariffs of 25% on certain steel products and of 10% on certain aluminium products. These tariffs apply to imports from all partner countries (including Switzerland), with the exception of those from Canada, Mexico, Argentina, Australia, Brazil and South Korea. However, steel and aluminium imports from Argentina are subject to quotas, as are steel imports from Brazil and South Korea.

Derivatives no longer subject to additional duty

On 24 January 2020 the USA announced that, for national security reasons, it would impose additional tariffs of 25% on certain derivative steel products and 10% on certain derivative aluminium products with effect from 8 February 2020. The US Court of International Trade declared these additional tariffs invalid on 5 April 2021.

WTO dispute settlement process – measures imposed by the USA on certain steel and aluminium products

Since 23 March 2018, the US has been applying additional duties of 25% on imports of certain steel products and 10% on imports of certain aluminium products, invoking national security reasons. Like eight other WTO members, Switzerland initiated WTO dispute settlement proceedings against these measures in 2018, considering them to be in violation of WTO law. The proceedings were delayed due to the COVID-19 pandemic and took more than four years in total. The panel notified the WTO of its ruling on 9 December 2022, concluding that the US measures violate several provisions of the GATT. and that they are not justified by the security exception invoked by the US.
