Trump's tariffs have launched global trade wars. Here's a timeline of how we got here

NEW YORK — Long-threatened tariffs from U.S. President Donald Trump have plunged the country into trade wars abroad — all while on-again, off-again new levies continue to escalate uncertainty.

Trump is no stranger to tariffs. He launched a trade war during his first term, taking particular aim at China by putting taxes on most of its goods. Beijing responded with its own retaliatory tariffs on U.S. products ranging from fruit to automotive imports. Meanwhile, Trump also used the threat of more tariffs to force Canada and Mexico to renegotiate a North American trade pact, called the U.S.-Mexico-Canada Agreement, in 2020.

When President Joe Biden took office, he preserved most of the tariffs Trump previously enacted against China, in addition to imposing some new restrictions — but his administration claimed to take a more targeted approach.

Fast-forward to today, and economists stress there could be greater consequences on businesses and economies worldwide under Trump's more sweeping tariffs this time around — and that higher prices will likely leave consumers footing the bill. There's also been a sense of whiplash from Trump's back-and-forth tariff threats and responding retaliation seen over the last few months.

Here's a timeline of how we got here:

January 20

Trump is sworn into office. In his inaugural address, he again promises to ''tariff and tax foreign countries to enrich our citizens." And he reiterates plans to create an agency called the External Revenue Service, which has yet to be established.

January 26

Trump threatens 25% tariffs on all Colombia imports and other retaliatory measures after President Gustavo Petro's rejects two U.S. military aircraft carrying migrants to the country, accusing Trump of not treating immigrants with dignity during deportation.

In response, Petro also announces a retaliatory 25% increase in Colombian tariffs on U.S. goods. But Colombia later reversed its decision and accepted the flights carrying migrants. The two countries soon signaled a halt in the trade dispute.

February 1

Trump signs an executive order to impose tariffs on imports from Mexico, Canada and China — 10% on all imports from China and 25% on imports from Mexico and Canada starting Feb. 4. Trump invoked this power by declaring a national emergency — ostensibly over undocumented immigration and drug trafficking.

February 3

Trump agrees to a 30-day pause on his tariff threats against Mexico and Canada, as both trading partners take steps to appease Trump's concerns about border security and drug trafficking.

February 4

Trump's new 10% tariffs on all Chinese imports to the U.S. still go into effect. China retaliates the same day by announcing a flurry of countermeasures, including sweeping new duties on a variety of American goods and an anti-monopoly investigation into Google.

China's 15% tariffs on coal and liquefied natural gas products, and a 10% levy on crude oil, agricultural machinery and large-engine cars imported from the U.S., take effect Feb. 10.

Trump announces plans to hike steel and aluminum tariffs starting March 12. He removes the exemptions from his 2018 tariffs on steel, meaning that all steel imports will be taxed at a minimum of 25%, and also raises his 2018 aluminum tariffs from 10% to 25%.

February 13

Trump announces a plan for ''reciprocal'' tariffs — promising to increase U.S. tariffs to match the tax rates that other countries charge on imports ''for purposes of fairness.'' Economists warn that the reciprocal tariffs, set to overturn decades of trade policy, could create chaos for global businesses.

Beyond China, Canada and Mexico, he later indicates that additional countries, such as India and European nations, won't be spared from higher tariffs.

February 25

March 1

Trump signs an additional executive order instructing the Commerce Department to consider whether tariffs on lumber and timber are also needed to protect national security, arguing that the construction industry and military depend on a strong supply of wooden products in the U.S.

March 4

Trump's 25% tariffs on imports from Canada and Mexico go into effect, though he limits the levy to 10% on Canadian energy. He also doubles the tariff on all Chinese imports to 20%.

All three countries promise retaliatory measures. Canadian Prime Minister Justin Trudeau announces tariffs on more than $100 billion of American goods over the course of 21 days. And Mexican President Claudia Sheinbaum says her country would respond with its own retaliatory tariffs on U.S. goods without specifying the targeted products immediately, signaling hopes to de-escalate.

March 5

Trump grants a one-month exemption on his new tariffs impacting goods from Mexico and Canada for U.S. automakers. The pause arrives after the president spoke with leaders of the ''Big 3'' automakers — Ford, General Motors and Stellantis.

March 6

In a wider extension, Trump postpones 25% tariffs on many imports from Mexico and some imports from Canada for a month. But he still plans to impose ''reciprocal'' tariffs starting on April 2.

Trump credited Sheinbaum with making progress on border security and drug smuggling as a reason for again pausing tariffs. His actions also thaw relations with Canada somewhat, although outrage and uncertainty remains. Still, after its initial retaliatory tariffs of $30 billion Canadian (US$21 billion) on U.S. goods, the government said it had suspended its second wave of retaliatory tariffs worth $125 billion Canadian (US$87 billion).

China's retaliatory 15% tariffs on key American farm products — including chicken, pork, soybeans and beef — take effect. Goods already in transit are set to be exempt through April 12, per China's Commerce Ministry previous announcement.

March 12

Trump's new tariffs on all steel and aluminum imports go into effect. Both metals are now taxed at 25% across the board — with Trump's order to remove steel exemptions and raise aluminum's levy from his previously-imposed 2018 import taxes.

The European Union takes retaliatory trade action promising new duties on U.S. industrial and farm products. The measures will cover goods from the United States worth some 26 billion euros ($28 billion), and not just steel and aluminum products, but also textiles, home appliances and agricultural goods. Motorcycles, bourbon, peanut butter and jeans will be hit, as they were during Trump's first term. The 27-member bloc later says it will delay this retaliatory action until mid-April.

Canada, meanwhile, announces plans to impose retaliatory tariffs worth Canadian $29.8 billion ($20.7 billion) on U.S. imports, set to go into effect March 13.

Trump threatens a 200% tariff on European wine, Champagne and spirits if the European Union goes forward with its previously-announced plans for a 50% tariff on American whiskey.

March 24

Trump says he will place a 25% tariff on all imports from any country that buys oil or gas from Venezuela, in addition to imposing new tariffs on the South American country itself, starting April 2.

The tariffs would most likely add to the taxes facing China, which in 2023 bought 68% of the oil exported by Venezuela, per the U.S. Energy Information Administration. But a number of countries also receive oil from Venezuela — including the United States itself.

March 26

These auto imports will start being collected April 3 — starting with taxes on fully-imported cars. The tariffs are set to then expand to applicable auto parts in the following weeks, through May 3.

April 2

Trump announces his long-promised ''reciprocal'' tariffs — declaring a 10% baseline tax on imports across the board starting April 5, as well as higher rates for dozens of nations that run trade surpluses with the U.S. to take effect April 9.

Among those steeper levies, Trump says the U.S. will now charge a 34% tax on imports from China, a 20% tax on imports from the European Union, 25% on South Korea, 24% on Japan and 32% on Taiwan. The new tariffs come on top of previously-imposed levies, including the 20% tax Trump announced on all Chinese imports earlier this year.

Meanwhile, for goods from Canada and Mexico, the White House says USMCA-compliant imports can continue to enter the U.S. duty free. Once the two countries have satisfied Trump's demands on immigration and drug trafficking, the White House adds, the tariff on the rest of their imports may drop from 25% to 12%.

Trump's previously-announced auto tariffs begin. Prime Minister Mark Carney says that Canada will match the 25% levies with a tariff on vehicles imported from the U.S.

April 4

China announces plans to impose a 34% tariff on imports of all U.S. products beginning April 10, matching Trump's new "reciprocal'' tariff on Chinese goods, as part of a flurry of retaliatory measures.

The Commerce Ministry in Beijing says it will also impose more export controls on rare earths, which are materials used in high-tech products like computer chips and electric vehicle batteries. And the government adds 27 firms to lists of companies subject to trade sanctions or export controls.

April 5

April 9

Trump's higher ''reciprocal'' rates go into effect, hiking taxes on imports from dozens of countries just after midnight. But hours later, his administration says it will suspend most of these higher rates for 90 days, while maintaining the recently-imposed 10% levy on nearly all global imports.

China is the exception. After following through on a threat to raise levies against China to a total of 104%, Trump says he will now raise those import taxes to 125% ''effective immediately'' — escalating tit-for-tat duties that have piled up between the two countries.

China upped its retaliation prior to this announcement — vowing to tax American goods at 84% starting April 10.

Canada's counter tariffs on auto imports also take effect. The country implements a 25% levy on auto imports from the U.S. that do not comply with the 2020 USMCA pact.

April 10

The White House clarifies that Trump's previously-announced 125% figure for tariffs against China is actually 145%, once his previous 20% fentanyl tariffs are accounted for.

Separately, the EU puts its steel and aluminum tariff retaliation on hold for 90 days, to match Trump's pause on steeper ''reciprocal'' levies. European Commission President Ursula von der Leyen says the commission wants to give negotiations with the U.S. a chance — but warns countermeasures will kick in if talks ''are not satisfactory.''
