U.S. customs agents began collecting President Donald Trump’s unilateral 10 per cent tariff on all imports from many countries on Saturday, with higher levies on goods from 57 larger trading partners due to start next week.
The initial 10 per cent “baseline” tariff to be paid by U.S. importers took effect at U.S. seaports, airports and customs warehouses at 12:01 a.m. ET (0401 GMT), ushering in Trump’s full rejection of the post-World War Two system of mutually agreed tariff rates.
“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 during Trump’s first term.
Shaw told a Brookings Institution event on Thursday that she expected the tariffs to evolve over time as countries seek to negotiate lower rates. “But this is huge. This is a pretty seismic and significant shift in the way that we trade with every country on earth,” she added.
Trump’s Wednesday tariff announcement shook global stock markets, wiping out $5 trillion in stock market value for S&P 500 .SPX companies by Friday’s close, a record two-day decline. Prices for oil and commodities plunged, while investors fled to the safety of government bonds.

Among the countries first hit with the 10 per centtariff are Australia, Britain, Colombia, Argentina, Egypt and Saudi Arabia. A U.S. Customs and Border Protection bulletin to shippers indicates no grace period for cargoes on the water at midnight on Saturday.

But a U.S. Customs and Border Protection bulletin did provide a 51-day grace period for cargoes loaded onto vessels or planes and in transit to the U.S. before 12:01 a.m. ET Saturday. These cargoes need arrive by 12:01 a.m. ET on May 27 to avoid the 10 per cent duty.
At the same hour on Wednesday, Trump’s higher “reciprocal” tariff rates of 11 per cent to 50 per cent are due to take effect. European Union imports will be hit with a 20 per cent tariff, while Chinese goods will be hit with a 34 per cent tariff, bringing Trump’s total new levies on China to 54 per cent.
Beijing on Saturday said “the market has spoken” in rejecting Trump’s tariffs after it hit Washington with a slew of countermeasures, including extra levies of 34 per cent on all U.S. goods and export curbs on some rare earth minerals.
“China has been hit much harder than the USA, not even close,” Trump said on Saturday on social media. “THIS IS AN ECONOMIC REVOLUTION, AND WE WILL WIN. HANG TOUGH, it won’t be easy, but the end result will be historic.”
Shortly after posting the comment, Trump was spotted arriving at his Trump National Golf Club in Jupiter, Florida, reading a New York Post article covering China’s retaliation to Trump’s tariffs and the stock market “crash.”
Some world leaders moved quickly to strike a deal with Trump to avert economic disruption while others weighed countermeasures.
Israeli Prime Minister Benjamin Netanyahu is expected to visit the White House on Monday, sources said, as unspecified goods from the country face a 17 per cent tariff under the new policy. Japanese Prime Minister Shigeru Ishiba was reportedly seeking a telephone conversation with Trump. Tokyo faces a 24 per cent levy.
Vietnam, which benefited from the shift of U.S. supply chains away from China after Trump’s first-term trade war with Beijing, will be hit with a 46 per cent tariff and agreed on Friday to discuss a deal with Trump.

The head of Taiwan’s National Security Council was in Washington for talks with the Trump administration that were expected to include the tariffs, a source said. Taiwan President Lai Ching-te huddled with tech executives on Saturday to discuss how to respond to the 32 per cent duty it faces on its products.
Italian Economy Minister Giancarlo Giorgetti warned on Saturday against the imposition of retaliatory tariffs on the United States, saying at a business forum near Milan that doing so could cause damage.
Canada and Mexico were exempt from both Trump’s latest duties because they are still subject to a 25 per cent tariff related to the U.S. fentanyl crisis for goods that do not comply with the U.S.-Mexico-Canada rules of origin.
Trump is excluding goods subject to separate, 25 per cent national security tariffs, including steel and aluminum, cars, trucks and auto parts.
His administration also released a list of more than 1,000 product categories exempted from the tariffs. Valued at $645 billion in 2024 imports, these include crude oil, petroleum products and other energy imports, pharmaceuticals, uranium, titanium, lumber and semiconductors and copper. Except for energy, the Trump administration is investigating several of these sectors for further national security tariffs.
