President Donald Trump is set to impose tariffs on Mexico and Canada this Tuesday, but the exact levels are still under consideration, according to Commerce Secretary Howard Lutnick.

Lutnick remarked on Fox's Sunday Morning Futures show that while Mexico and Canada have made significant efforts to address Trump's concerns regarding border crossings, they have not sufficiently tackled his worries about "fentanyl deaths in America." He added, "Trump is thinking about how exactly he wants to play it with Mexico and Canada, and that is a fluid situation."

On Sunday, Trump amended two executive orders to exclude low-value shipments from the upcoming tariffs on imports from Canada and Mexico. This decision could indicate the White House's commitment to moving forward with the tariffs, which had previously been paused for 30 days to allow for negotiations.

In addition to the tariffs on Mexico and Canada, Trump plans to impose an additional 10% tariff on China, which is already confirmed, according to Lutnick. This new tariff will be on top of the 10% tariffs that were implemented earlier this month.

Although Trump previously suggested imposing 25% tariffs on Mexico and Canada, Lutnick indicated that the final figure could be lower. His comments suggest that Mexico and Canada may make a last-ditch diplomatic effort to avert these measures, which Trump had delayed once before last month.

"He's going to think about it. He's going to put them into place on Tuesday. The Canadians and the Mexicans have been talking to him," Lutnick said.

Trump has also hinted at extending his global trade war to Canada's lumber industry after directing the Commerce Department to investigate dumping into the U.S. market.

Meanwhile, China appears to have limited options ahead of Tuesday's deadline. The country has vowed to implement countermeasures to protect its interests, having tightened controls on precursor chemicals and fentanyl-like substances.

Lutnick noted, "If they think they're going to retaliate, remember they have so much more that they sell to us than we sell to them."
