Tariffs Becoming Policy
Tariffs are now being wielded as a central instrument of U.S. economic policy in what commentators call a 'Trump 2.0' approach, expanding their use beyond isolated disputes. That shift matters for companies because the effects are uneven — Canadian analysis shows firms less tied exclusively to U.S. demand have sometimes been insulated by broader global customers. The threat of a 50% tariff on arms suppliers tied to the Iran ceasefire episode shows how trade pressure can be layered onto geopolitical events. (tradecomplianceresourcehub.com) (rbc.com) (scmp.com)
On April 8, President Donald Trump’s trade team was tracking a 10% across-the-board import surcharge already in effect under Section 122, while Trump also threatened a new 50% tariff on any country that supplies military weapons to Iran. That is a very different use of tariffs from the old model of targeting one product or one country at a time. (tradecomplianceresourcehub.com) (scmp.com) The Reed Smith tariff tracker says the Supreme Court ruled on February 20, 2026 that the International Emergency Economic Powers Act does not authorize the president to impose tariffs, which knocked out that earlier legal route. The administration then shifted to other tools, including Section 122, which allows a temporary surcharge that the tracker lists at 10% effective February 24, 2026 and ending July 24, 2026 unless extended. (tradecomplianceresourcehub.com) That is why tariffs now look less like a border tax and more like a pressure tactic that can be swapped in wherever Washington wants leverage. The same tracker lists threatened tariffs tied to digital services taxes, Russian-origin energy trade, and now Iran weapons supply, all sitting next to ordinary country and product measures on one board. (tradecomplianceresourcehub.com) The Iran example shows how far this has moved into foreign policy. South China Morning Post reported on April 8 that Trump praised China’s role in a ceasefire push and then threatened 50% tariffs on countries supplying weapons to Iran, even as Tehran kept the Strait of Hormuz closed and warned it could walk away from the deal if Israeli attacks on Lebanon continued. (scmp.com) This was not the first Iran tariff threat this year. On January 13, South China Morning Post reported that Trump announced a 25% tariff on goods and services from any country that “does business” with Iran, a move aimed most directly at countries with larger commercial ties to Tehran such as China and India. (scmp.com) Once tariffs are used that way, companies stop asking only “what do we import” and start asking “who do we sell to, where do our customers sell, and what other dispute could get folded into our supply chain next month.” A steel buyer, a chipmaker, and an arms subcontractor can all end up in the same policy blast radius for completely different reasons. (tradecomplianceresourcehub.com) (scmp.com) The Canadian evidence shows why the damage does not land evenly. Royal Bank of Canada wrote on April 8 that tariffs under the second Trump administration covered more than 70% of total United States imports in 2024 at their peak, but economies outside North America were less exposed because the United States is a smaller share of their exports, including about 30% for Vietnam, 15% for China, and 9% for the euro area in 2024. (rbc.com) Royal Bank of Canada also found that overall United States imports still rose 2.7% in 2025, excluding price effects, while the United States trade deficit widened slightly to negative $926 billion. The volume kept moving, but the map changed, with less coming from China and more coming from places like Vietnam, Taiwan, and Thailand. (rbc.com) That is the new pattern in one line: tariffs are no longer just a wall; they are a steering wheel. They redirect trade flows, reward firms with broader customer bases, and let Washington attach economic penalties to fights over taxes, oil, shipping lanes, or ceasefires without waiting for a traditional sanctions package.
