Manufacturers and business groups slammed President Donald Trump’s decision to impose tariffs on steel and aluminum imports from the European Union, Canada and Mexico, warning of promised retaliation and calling it a tax on U.S. companies and consumers.

The U.S. Chamber of Commerce urged the administration on the eve of Thursday’s announcement not to proceed because the tariffs would hit U.S. manufacturers with higher costs, impede construction-sector growth and hurt job creation in both industries. Expected widespread retaliation from abroad would also threaten the economic momentum the administration has achieved through tax and regulatory reform, the chamber said.
