President Donald Trump has announced that he’s imposing a tariff on goods from some of the US’s biggest trade partners: Canada, Mexico, and China. Under the executive orders signed on February 1st, Canada and Mexico will face a 25 percent tariff, while goods from China will be subject to a 10 percent tax. Energy resources from Canada will also have a lower 10 percent tariff.

Trump positioned the tariffs as a way to “halt the flood of poisonous drugs into the United States,” referring to fentanyl. The change will have a big impact on the cost of a wide variety of goods imported from each country, including electronics, produce, clothing, and much more.
