India and Japan have notified the WTO of plans to impose retaliatory tariffs on US imports in response to increased steel and aluminum duties imposed by the Trump administration.

Both countries argue the US tariffs, in place since 2018 and expanded in March 2025, qualify as safeguard measures under WTO rules, entitling them to suspend equivalent trade concessions, Xinhua reported.

India claims that the tariffs affect $7.6bn of its exports and will equal $1.91bn in taxes with equivalent tariffs on US imports. Japan intends to take similar action, targeting US limits on auto imports.

The EU and UK have already filed comparable WTO notifications, according to Xinhua.
