Trump Tariffs

A history of the tariffs under Trump.


First Administration

TODO: learn some history!


Second Administration

Immediate Program

Immediate actions taken by Trump upon election were largely targeted at China, Mexico, and Canada.

The measures set against Mexico and Canada quickly dissolved. First, temporary exceptions were made for specific manufacturers, especially automotive manufacturers, for imports from Canada and Mexico that are compliant with USMCA. Then the implementation was delayed entirely.

Similarly, the de minimis implementation quickly fell through. USPS and CBP were not prepared to process duties for this quantity of small parcels, so parcel services with China and Hong Kong were closed immediately. The fallout of this closure forced the administration to delay implementation entirely.

It is nonetheless important to note that the anticipation of a tariff war contributed to the downfall of the Trudeau government. Trudeau and Freeland disagreed on how to respond to the threat, and the latter's resignation triggered a loss of confidence. Trudeau resigned and announced a leadership contest, through which Carney emerged the winner. In the meantime, provincial governments retaliated within their powers. Ontario announced export fees on energy and threatened to ban energy exports entirely. Several provinces, such as British Columbia, effectively banned importation of American alcohol through their control of alcohol distribution.

Section 232 Program

There was also an attempt at a tariff program based on determinations of national security. This is largely concerned with cars, steel, and aluminum. These tariff powers are derived from section 232 of the Trade Expansion Act in 1962.

In March, tariffs were set at 25% on all car, steel, and aluminum imports. This led to several reciprocal tariffs being set against the U.S.:

In June, these rates were doubled to 50%. As well, the DoC determined that appliances made of steel are covered by steel tariffs.

Reciprocal Program

In April 2025, a 'standardized' tariff program was announced.

China became a nexus for the trade war. Jinping announced retaliatory tariffs on American agriculture and export controls on specific manufacturers. A sequence of ratcheting escalations landed on tariff rates of 145% (into U.S.) and 125% (into China). In an attempt to make the rates more punishing, Trump announced that the reciprocal tariffs for all other countries were frozen for 3 months.

Unexpectedly though, a bilateral agreement emerged in early May that set a framework for lowering tariff rates to 30% (into U.S.) and 10% (into China). This deal was briefly reneged at the end of May on the basis of rare earths export controls, but re-entered within a couple weeks.

Aside from China, these bilateral trade deals emerged within the freeze period:

In contrast, several countries were targeted with further actions in July. The context however reveals that these tariff actions are about geopolitics rather than trade.

The de minimis exemption was closed on parcels from China in April, will be closed for all countries effective August 29.
