WASHINGTON >> Tariffs on imports from Canada and Mexico will go into effect on March 4 “as scheduled,” President Donald Trump said Thursday, claiming that those countries were still not doing enough to stop the flow of drugs into the United States.

China will also face an additional 10% tariff next week, on top of the 10% Trump imposed earlier this month, the president wrote in a post on Truth Social.

“Drugs are still pouring into our Country from Mexico and Canada at very high and unacceptable levels,” he said. “A large percentage of these Drugs, much of them in the form of Fentanyl, are made in, and supplied by, China.” He added that the levies were necessary until the flow of drugs “stops, or is seriously limited.”

In the Oval Office on Thursday afternoon, Trump said progress had been made on reducing the flow of migrants, but said he hadn’t seen that same progress on drugs, particularly fentanyl.

“The drugs continue to pour into our country, killing hundreds of thousands of people,” he said.

Trump threatened to impose tariffs on all products from Canada, Mexico and China in early February, an effort he said was aimed at stemming the flow of both migrants and drugs. But after Mexico and Canada promised measures like sending more troops to the border and, in the case of Canada, appointing a “fentanyl czar,” Trump paused their tariffs for one month.He moved ahead with imposing a 10% tariff on all products from China, on top of those already in place, which prompted China to retaliate with its own tariffs on U.S. goods.

Now, Trump said Thursday, he will proceed with an additional 10% tariff on Chinese goods, a decision he had not previously announced. Those tariffs will be added on top of the 10% to 25% tariffs that Trump imposed on more than $300 billion of products from China in his first term, which are largely still in effect.

“It’s 10 plus 10,” Trump said, making clear that the 10% on March 4 would be in addition to the existing 10% that went into place on Feb. 1.

Since Trump revealed plans for tariffs on the three countries in late January, the Mexican and Canadian governments have been furiously working to defuse tensions and persuade Trump that they have been working to police their borders.

China’s efforts, in contrast, appear to have been more muted. Trump’s threat of an additional tariff could be an effort to bring the Chinese to the table for more negotiations.

Possible affects

Trump intends to put 25% tariffs on imports from Mexico and Canada, with a lower 10% tax on Canadian energy products such as oil and electricity.

Additional tariffs on the country’s three biggest trading partners would only add to the economic strain that has begun to emerge from Trump’s flurry of actions. Companies that import car parts, medical devices, vegetables and clothing into the United States are once again grappling with how they will absorb the additional costs.

Three textile associations issued a joint statement Thursday urging the president to reach a deal with Mexico and Canada and avoid imposing the 25% tariff, arguing that the three countries had an integrated North American supply chain that generated $20 billion in trade and supported more than 1.6 million jobs.

The U.S. textile industry ships $12.3 billion, or 53%, of its total global textile exports to Mexico and Canada, which come back as finished products to the United States under the United States-Mexico-Canada Agreement, the groups said. Trump negotiated the terms of the agreement during his first term and the president signed the trade deal in 2020.

Jay Foreman, the CEO of toy company Basic Fun, which manufactures toys such as Tonka Trucks and Lincoln Logs in China, said the additional 10% tariff on China was a “nightmare.” His company was scrambling “to figure out how best to handle and mitigate” the tariffs, he said.

“We just figured out how to work with 10%. There is no way we can find a way to absorb 20%. It must get fully passed along,” he said, indicating that costs for consumers would rise.

Countries respond

Canadian and Mexican officials have been trying to dissuade the Trump administration from moving forward with the tariffs, including in meetings with Commerce Secretary Howard Lutnick this week.

Trump’s threats have posed a particular quandary for Canadian officials, who argue that fentanyl made in Canada has not posed an increasing threat to the United States.

Last year, U.S. Customs and Border Protection agents intercepted about 19 kilograms of fentanyl at the U.S.-Canadian border, compared with almost 9,600 kilograms at the border with Mexico, where cartels mass-produce the drug. A 2020 congressional commission that looked into reducing the flow of drugs into the United States found that Canada was not known to be a major source of fentanyl or its precursor chemicals.

Canadian Prime Minister Justin Trudeau said his country has invested more than 1 billion Canadian dollars to improve border security, adding that his government’s ministers and officials are also in Washington this week.

Mexico, in contrast, is a major source of fentanyl shipments. In recent months, the Mexican government has widened its operations in the Sinaloa state, with a burst of high-level arrests, drug lab busts and drug seizures rocking the operations of the Sinaloa cartel there.

After Trump came to the brink of imposing a 25% tariff on Mexican exports earlier this month, Mexican President Claudia Sheinbaum dispatched 10,000 national guard troops to the border and sent hundreds more soldiers to Sinaloa.

It remains unclear if those efforts will be enough to mollify Trump. His post Thursday appeared to be an attempt to clarify the timing for his various tariffs after his remarks at the White House on Wednesday sowed confusion about whether the March 4 levies had been delayed.

When asked about tariffs on Canada and Mexico on Wednesday, Trump said that they would proceed — but mentioned April 2, which is when he has said another batch of tariffs on various countries, which he has called reciprocal tariffs, would go into effect.

Some investors interpreted those remarks as a sign the president meant to continue delaying the tariffs related to drugs and migrants, and the value of the peso and the Canadian dollar increased. But a White House official Wednesday clarified that the April 2 date referred to other tariffs, not those on Canada and Mexico.

“The April Second Reciprocal Tariff date will remain in full force and effect,” Trump wrote Thursday.

Who pays?

Asked Thursday about whether tariffs are largely paid for consumers and importing companies, Trump dismissed any concerns by saying: “It’s a myth.” It’s possible for a stronger U.S. dollar to offset some of the costs of tariffs, but Trump’s statement goes against most economic modeling given the breadth of his planned taxes.

The 25% tariffs on Mexico and Canada would amount to a total tax increase on the U.S. public of somewhere between $120 billion to $225 billion annually, according to Jacob Jensen, a trade policy analyst at the American Action Forum, a center-right think tank. The additional China tariffs could cost consumers up to $25 billion.
