The U.S. economy entered a new era at 12:01 a.m. Tuesday, as President Trump’s tariffs on imports from Mexico and Canada took effect. The new tariffs on imported goods ended decades of free trade among the three countries, and stood to disrupt entire industries.

The 25% tariffs will be levied on imports from Mexico and Canada, with the exception of energy products such as crude oil and natural gas, which will be tariffed at 10%. Canada said it would impose retaliatory tariffs.
