WASHINGTON: U.S. President Donald Trump has raised tariffs on steel and aluminum imports to 25 percent, on Monday, removing all previous exemptions and exceptions. This decision aims to support American industries but could lead to more trade conflicts.

Trump signed an order increasing the tariff on aluminum from 10 percent  to 25 percent  and canceling special deals that allowed certain countries to avoid these taxes. The new rules take effect on March 4, a White House official confirmed.

These tariffs will now apply to steel and aluminum from countries like Canada, Brazil, Mexico, and South Korea, which were previously exempt. Trump said the change makes things clearer: "It's 25 percent  for everyone, no exceptions." However, he mentioned he might consider an exemption for Australia due to its trade deficit with the U.S.

The decision expands Trump's 2018 tariffs, which were introduced for national security reasons. A White House official said earlier exemptions had weakened the policy.

Additionally, Trump announced a new rule requiring steel imports to be fully produced in North America. This is meant to stop partially processed metals from China and Russia from avoiding tariffs. The tariffs will also cover products made with foreign steel, such as structural steel and aluminum parts.

Trump hinted that more tariff announcements would follow, possibly affecting cars, semiconductor chips, and pharmaceuticals. When asked about other countries retaliating, he said, "I don't mind."

His trade adviser, Peter Navarro, said the move would strengthen national security and boost local production. He claimed it would stop unfair foreign competition and support American industry.

In recent years, U.S. aluminum production has dropped significantly. The country now depends on imports, with Canada supplying nearly 80 percent  of its aluminum in 2024.

Earlier this month, Trump threatened to impose a 25 percent tariff on Canadian and Mexican goods but delayed the plan for 30 days after talking to leaders from both countries. He also added a 10 percent tariff on all Chinese goods, and China responded with its own set of tariffs.
