WASHINGTON (AP) — Donald Trump loved to use tariffs on foreign goods during his first presidency. But their impact was barely noticeable in the overall economy, even if their aftershocks were clear in specific industries.
The data show they never fully delivered on his promised factory jobs. Nor did they provoke the avalanche of inflation that critics feared.
This time, though, his tariff threats might be different.
The president-elect is talking about going much bigger — on a potential scale that creates more uncertainty about whether he’ll do what he says and what the consequences could be.
“There’s going to be a lot more tariffs, I mean, he’s pretty clear,” said Michael Stumo, the CEO of Coalition for a Prosperous America, a group that has supported import taxes to help domestic manufacturing.
The president-elect posted on social media Monday that on his first day in office he would impose 25% tariffs on all goods imported from Mexico and Canada until those countries satisfactorily stop illegal immigration and the flow of illegal drugs such as fentanyl into the United States.
Those tariffs could essentially blow up the North American trade pact that Trump’s team negotiated during his initial term.
Chinese imports would face additional tariffs of 10% until Beijing cracks down on the production of materials used in making fentanyl, Trump posted.
Democrats and business groups warn of risks from Trump’s tariff threats
Business groups were quick to warn about rapidly escalating inflation, while Mexican President Claudia Sheinbaum said she would counter the move with tariffs on U.S. products. House Democrats put together legislation to strip a president’s ability to unilaterally apply tariffs this drastic, warning that they would likely lead to higher prices for autos, shoes, housing and groceries.
Sheinbaum said Wednesday that her administration is already working up a list of possible retaliatory tariffs “if the situation comes to that.”
“The economy department is preparing it,” Sheinbaum said. “If there are tariffs, Mexico would increase tariffs, it is a technical task about what would also benefit Mexico,” she said, suggesting her country would impose targeted import duties on U.S. goods in sensitive areas.
House Democrats on Tuesday introduced a bill that would require congressional approval for a president to impose tariffs due to claims of a national emergency, a largely symbolic action given Republicans’ coming control of both the House and Senate.
“This legislation would enable Congress to limit this sweeping emergency authority and put in place the necessary Congressional oversight before any president – Democrat or Republican – could indiscriminately raise costs on the American people through tariffs,” said Rep. Suzan DelBene, D-Wash.
But for Trump, tariffs are now a tested tool that seems less politically controversial even if the mandate he received in November’s election largely involved restraining inflation.
The tariffs he imposed on China in his first term were continued by President Joe Biden, a Democrat who even expanded tariffs and restrictions on the world’s second largest economy. Biden administration officials looked at removing Trump’s tariffs in order to bring down inflationary pressures, only to find they were unlikely to help significantly.
Tariffs were “so new and unique that it freaked everybody out in 2017,” said Stumo, but they were ultimately somewhat modest.
Trump’s first term tariffs had a modest impact on economy
Trump imposed tariffs on solar panels and washing machines at the start of 2018, moves that might have pushed up prices in those sectors even though they also overlapped with plans to open washing machine plants in Tennessee and South Carolina.
His administration also levied tariffs on steel and aluminum, including against allies. He then increased tariffs on China, leading to a trade conflict and a limited 2020 agreement that failed to produce the promised Chinese purchases of U.S. goods.
Still, the dispute changed relations with China as more U.S. companies looked for alternative suppliers in other countries. Economic research also found the United States may have sacrificed some of its “soft power” as the Chinese population began to watch fewer American movies.
The Federal Reserve kept inflation roughly on target, but factory construction spending never jumped in a way that suggested a lasting gain in manufacturing jobs. Separate economic research found the tariff war with China did nothing economically for the communities hurt by offshoring, but it did help Trump and Republicans in those communities politically.
When Trump first became president in 2017, the federal government collected $34.6 billion in customs, duties and fees. That sum more than doubled under Trump to $70.8 billion in 2019, according to Office of Management and Budget records.
While that sum might seem meaningful, it was relatively small compared to the overall economy. America’s gross domestic product is now $29.3 trillion, according to the Bureau of Economic Analysis. The total tariffs collected in the United States would equal less than 0.3% of GDP.
Trump wants much more far-reaching tariffs going forward
The new tariffs being floated by Trump now are dramatically larger and there could be far more significant impacts.
If Mexico, Canada, and China faced the additional tariffs proposed by Trump on all goods imported to the United States, that could be roughly equal to $266 billion in tax collections, a number that does not assume any disruptions in trade or retaliatory moves by other countries. The cost of those taxes would likely be borne by U.S. families, importers and domestic and foreign companies in the form of higher prices or lower profits.
Former Biden administration officials said they worried that companies could piggyback on Trump’s tariffs — if they’re imposed — as a rationale to raise their prices, just as many companies after Russia’s invasion of Ukraine in 2022 boosted food and energy costs and gave several major companies the space to raise prices, according to their own earnings calls with investors.
But what Trump didn’t really spell out is what might cause him to back down on tariffs and declare a victory. What he is creating instead with his tariff threats is a sense of uncertainty as companies and countries await the details to figure out what all of this could mean.
“We know the key economic policy priorities of the incoming Trump administration, but we don’t know how or when they will be addressed,” said Greg Daco, chief U.S. economist at EY-Parthenon.
