At 12:01 a.m. Eastern Time on Saturday, US customs officers began collecting Donald Trump’s new 10% “baseline” tariff on imports, marking the most dramatic shift in American trade policy since the end of the Second World War.
It’s the start of something much bigger. On April 9, even steeper levies—between 11% and 50%—will hit goods from 57 countries, including close allies like the UK, Japan, and the entire European Union.
"This is the single biggest trade action of our lifetime," said Kelly Ann Shaw, a trade lawyer at Hogan Lovells and former White House trade adviser under Trump. Speaking at a Brookings Institution event, Shaw added, “This is huge. This is a pretty seismic and significant shift in the way that we trade with every country on earth.”
That shift is already rippling through global markets and political capitals.
Then came retaliation.
China, facing a 34% tariff that pushes total US duties on its goods to 54%, announced it would match the move and impose its own 34% levy on American exports from April 10. Beijing also plans to file a case against the US at the World Trade Organization and restrict exports of rare earth metals—critical for electronics and medical technology.
Trump’s response was blunt. “China played it wrong,” he posted on Truth Social. “They cannot afford to do this.”
Still, most other US trading partners appear to be watching and waiting, trying to gauge how deep the standoff might go and what it could mean for the global economy.
More than 1,000 product categories are temporarily spared, including crude oil, energy imports, semiconductors, pharmaceuticals, copper, titanium, lumber and uranium. These accounted for $645 billion of US imports in 2024. Yet many of these sectors—aside from energy—are already under review for potential “national security” tariffs.
Steel, aluminium, cars and car parts, already covered by separate 25% duties, are also exempt from the latest round.
Canada and Mexico are not part of this new tariff regime. But that doesn’t mean they’re off the hook. They’re still subject to existing 25% tariffs for goods not aligned with the US-Mexico-Canada Agreement, tied to concerns over immigration and fentanyl trafficking.
Vietnam, which had gained from the earlier shift in US supply chains away from China, now finds itself in the crosshairs. A hefty 46% tariff is on its way. After Trump’s announcement, Hanoi agreed to talks to avoid a protracted dispute.
Among the first to feel the pinch are Australia, Britain, Colombia, Argentina, Egypt and Saudi Arabia. A US Customs and Border Protection bulletin confirmed there would be no grace period for cargo already at sea when the tariffs took effect.
There is, however, a narrow window for relief. Goods that were already en route by the Saturday deadline have until 12:01 a.m. ET on May 27 to arrive, or they too will be taxed at the new 10% rate.
Oxford Economics predicts that Trump's new trade policy will raise the average US tariff rate to 24%—higher than during the Great Depression. “If they can't get a reprieve,” the firm warned, “they are likely to retaliate, as China already has.”
"If they can't get a reprieve, they are likely to retaliate, as China already has," warned a report by Oxford Economics.
The European Union has made its displeasure clear. Trade Commissioner Maros Sefcovic said the bloc would act in "a calm, carefully phased, unified way" but added it "won’t stand idly by." France and Germany have suggested the EU could hit back with taxes on major US tech firms.
Japan's Prime Minister urged a “calm-headed” approach after the US slapped a 24% tariff on Japanese goods. Trump, meanwhile, claimed a “very productive” call with Vietnam’s top leader after unveiling the 46% tariff on the Southeast Asian exporter.
France and Germany have already floated the idea of taxing US tech giants in return.
Stellantis, the parent company of Jeep, paused production at some Canadian and Mexican factories following Trump’s fresh 25% duties on autos.
Trump has claimed progress elsewhere. He described a recent call with Vietnam’s leader as "very productive," although Vietnam now faces one of the highest new duties—46 percent—on its exports to the US.
But critics warn this isn’t just about economics—it’s about power.
The scale of Trump’s tariffs is raising historical comparisons. According to the Center for Strategic and International Studies, the new levies represent "the most sweeping tariff hike since the Smoot-Hawley Tariff Act," a 1930 law widely blamed for deepening the Great Depression.
And the numbers are staggering. Oxford Economics estimates that the average effective US tariff rate will soon rise to 24 percent. That’s higher than at any point in the last century—even in the 1930s.
In addition to the 10 percent base tariff and the upcoming 34 percent increase on Chinese goods, Trump has introduced a 25 percent auto tariff and an extra 20 percent on a separate batch of Chinese imports. The cumulative effect means Chinese goods will face a 54 percent duty from April 9.
For now, Trump's message is clear: this is not a negotiating tactic. It's policy. But with inflation fears growing, global supply chains under pressure, and markets reacting sharply, the full consequences of this strategy may take months—or years—to unfold.
Trump, however, remains unmoved. "My policies will never change," he wrote on his social platform.
For the rest of the world, the question now is: fight, fold, or wait it out? Because the tariffs are here, the clock is ticking—and the costs are already being felt.

Global markets shudder, China hits back
Just days after Trump unveiled the move, markets plunged. By Friday evening, $5 trillion had been wiped from S&P 500 companies alone in a historic two-day slide. Oil and commodity prices nosedived. Investors ran for cover in government bonds.Then came retaliation.

Exemptions are narrow. The risks are not.
Despite the sweeping nature of the tariffs, there are carve-outs—for now.More than 1,000 product categories are temporarily spared, including crude oil, energy imports, semiconductors, pharmaceuticals, copper, titanium, lumber and uranium.

No grace period, limited relief

Retaliation brewing in Europe and Asia
The staggered rollout of tariffs allows time for negotiation. But experts believe some countries won’t wait long to strike back."If they can't get a reprieve, they are likely to retaliate, as China already has," warned a report by Oxford Economics.

A return to old trade wars?
With these moves, Trump has formally rejected the post-WWII system of mutual tariff setting. Instead, he’s invoking emergency economic powers to pursue what he calls “reciprocal” trade. The White House blames America’s ballooning trade deficits on unfair value-added taxes and a lack of balance in global deals.But critics warn this isn’t just about economics—it’s about power.
