Tariffs for Canada and Mexico were implemented on March 4th 2025.
Additionally, President Trump issued a new executive order increasing the additional tariff on products from China from 10% to 20%. Following the order, a separate notice was issued clarifying that the additional 10% tariff on products from China (and Hong Kong) went into effect on March 4, 2025 (meaning that it is not retroactive, as suggested by the language of the Executive Order). So, for China, the additional 10% duty applies from February 4, 2025, through March 3, 2025, jumping to 20% from March 4, 2025 onwards.
The sizable additional tariffs on Canada and Mexico upend decades of economic relationship building and will have implications for all of North America. It is difficult to imagine tariffs at these levels being in effect for very long without significant economic harm to all three countries.
China and Canada have retaliated against imports from the United States (and against U.S. companies, in the case of China). Thus far, Mexico has not taken any action. There is still hope, of course, that agreements will be reached. It is vital to remember that the tariff options are not simply 25% or 0%, there is room to arrive at a more reasonable solution.
As for China, the increase from 10% to 20% is an effort to get China to engage with the United States on trade issues (something that did not occur following the first round of tariff increases, unlike with other countries). The China tariff is likely longer term, although a negotiated resolution is always possible (less likely with China, in most experts’ views, but still possible).

Importers, please be advised that the HTSUS numbers for the tariffs are automatically being applied based on the origin of the goods at the time of entry. You don't have to add anything to your invoices or systems; it automatically defaults to adding the applicable chapter 99 to the lines.
