Trump's steel, aluminum tariffs take effect as global trade war intensifies

WASHINGTON: US President Donald Trump's increased tariffs on all US steel and aluminum imports took effect on Wednesday (Mar 12), stepping up a campaign to reorder global trade norms in favor of the US that drew swift retaliation from Europe.
Trump's action to bulk up protections for American steel and aluminum producers restores effective global tariffs of 25 per cent on all imports of the metals and extends the duties to hundreds of downstream products made from the metals, from nuts and bolts to bulldozer blades and soda cans.
The European Commission responded almost immediately, saying it would impose counter tariffs on €26 billion (US$28 billion) worth of US goods from next month.
The commission said it will end the current suspension of tariffs on US products on Apr 1 and will also put forward a new package of countermeasures on US goods by mid-April.
"This matches the economic scope of the US tariffs. Our countermeasures will be introduced in two steps. Starting with Apr 1 and fully in place as of Apr 13," Ursula von der Leyen, president of the European Commission, said in a statement.
Close US allies Canada, Britain and Australia criticised the blanket tariffs, with Canada mulling reciprocal actions and British Business and Trade Secretary Jonathan Reynolds saying "all options were on the table" to respond in the national interest.
Australian Prime Minister Anthony Albanese said the move was "entirely unjustified ... and against the spirit of our two nations' enduring friendship" but ruled out tit-for-tat duties.
"Tariffs and escalating trade tensions are a form of economic self-harm, and a recipe for slower growth and higher inflation. They are paid by the consumers," Albanese told reporters.
The countries most affected by the tariffs are Canada, the biggest foreign supplier of steel and aluminum to the US, Brazil, Mexico and South Korea, which all have enjoyed some level of exemptions or quotas.
The runup to the tariff deadline came with some drama on Tuesday as Trump threatened Canada with doubling the duty to 50 per cent on its steel and aluminum exports to the US.
But Trump backed off those plans after Ontario Premier Doug Ford agreed to suspend his province's decision to impose a 25 per cent surcharge on electricity exports to the states of Minnesota, Michigan and New York until earlier US tariffs were removed.
Ford said he would fly to Washington on Thursday with Canadian Finance Minister Dominic LeBlanc for talks with Commerce Secretary Howard Lutnick and other Trump officials to discuss revising the US-Mexico-Canada Agreement on trade.
The incident whip-sawed US financial markets already jittery over Trump's broad tariff offensive, but left unchanged Trump's original plans to strengthen the Section 232 national security tariffs on steel and aluminum imposed in 2018 during his first term.
A White House spokesperson described the US pressure on Canada as a "win" for the American people.
The US Customs and Border Protection agency cut off imports qualifying for duty-free entry under quota arrangements well before the midnight deadline, saying in a bulletin to shippers that quota paperwork needed to be processed by 4.30p.m. local time on Tuesday at US ports of entry or the full tariffs would be charged.
The move was welcomed by US steel producers as restoring Trump's original 2018 metals tariffs that had been weakened by numerous country exclusions and quotas and thousands of product-specific exclusions.
"By closing loopholes in the tariff that have been exploited for years, President Trump will again supercharge a steel industry that stands ready to rebuild America," Steel Manufacturers Association President Philip Bell said in a statement.
"The revised tariff will ensure that steelmakers in America can continue to create new high-paying jobs and make greater investments knowing that they will not be undercut by unfair trade practices," Bell added.
The escalation of the US-Canada trade war occurred as Prime Minister Justin Trudeau prepared to hand over power this week to his successor Mark Carney, who won the leadership race of the ruling Liberals last weekend.
On Monday, Carney said he could not speak with Trump until he was sworn in as prime minister. Trump again on social media said he wanted Canada "to become our cherished Fifty First State".
Canadian Energy Minister Jonathan Wilkinson told Reuters that Canada could impose non-tariff measures such as restricting oil exports to the US or levying export duties on minerals, if US tariffs persist.
Canada ships about 4 million barrels of crude to the US per day via pipeline, mainly to Midwest refineries. Canadian tariffs on American ethanol are also an option, he added.
Most US-Canada trade remains duty free under the USMCA trade deal that Trump signed in 2020, but he continues to complain about Canada's high tariff rates for dairy products.
Ottawa last week won a month's reprieve for USMCA-compliant exports from Trump's general 25 per cent tariffs for Canada threatened over fentanyl trafficking.
But in early April, Canada also faces Trump's reciprocal tariffs aimed at raising US tariffs to match other countries' rates and counteract non-tariff barriers.
Canada, with ample hydropower resources that has made primary aluminum production more cost effective than in the US, has built a commanding position in the US aluminum market, as US smelters once revived by Trump's tariffs have been idled.
China remains the number two supplier of aluminum and goods made from aluminum, but already faces high tariffs to counteract alleged dumping and subsidies, as well as a new 20 per cent tariff that Trump has imposed over the past month over fentanyl trafficking.
Trump's hyper-focus on tariffs since taking office in January has rattled investor, consumer and business confidence in ways that economists increasingly worry could cause a US recession.
A small business survey on Tuesday showed sentiment weakening for a third straight month, fully eroding a confidence boost following Trump's Nov 5 election victory, and a survey of households by the New York Federal Reserve on Monday showed consumers growing more pessimistic about their finances, inflation and the job market.
