President Donald Trump, aboard Air Force One on Sunday night en route back to Washington, D.C., after a weekend in Florida, said there "shouldn't be ambiguity" amid his administration's repeated about-faces on tariffs.

He said semiconductor tariffs “will be in place in the not distant future” and that he would announce at what rate “over the next week.”

The president said on Saturday he would announce specifics on Monday.

Trump, when asked if he would declare tariffs on iPhones and tablets, said, "That’s going to be announced very soon" but that the administration is going to with companies about it because “you have to show a certain flexibility.”

China says the Trump administration’s exemptions for smartphones, laptops and other electronics is a “small step” in correcting a “wrong practice,” urging the U.S. to completely cancel Trump’s reciprocal tariffs.

"We urge the US … to take a big step to correct its mistakes, completely cancel the wrong practice of 'reciprocal tariffs' and return to the right path of mutual respect," China's Commerce Ministry said in a statement.

Beijing is now “evaluating the impact” of the exemption, the statement said.

Hedge fund billionaire and vocal Trump supporter Bill Ackman posted on X today: “The rift is healing. China ‘asks’ for relief from the tariffs creating an opening for a 90-day China tariff pause and negotiations.” Ackman had earlier in the week urged Trump to pause those reciprocal tariffs shortly before the president announced the pause, warning that businesses would go bankrupt.

But on Sunday afternoon, Trump posted on Truth Social that tariffs on these products are “just moving to a different Tariff ‘bucket.’”

“NOBODY is getting ‘off the hook’ for the unfair Trade Balances,” the president added. “Especially not China, which, by far, treats us the worst!”

Trump on Sunday said, “There was no Tariff ‘exemption’ announced on Friday" and that semiconductor tariffs will “just be moving to a different Tariff ‘bucket.’”

“NOBODY is getting ‘off the hook’ for the unfair Trade Balances, and Non Monetary Tariff Barriers, that other Countries have used against us, especially not China which, by far, treats us the worst!” Trump posted on his Truth Social platform.

Trump’s top economic and trade aides made the same argument on Sunday talk shows: that smartphones, computers and other electronics were removed from the sweeping reciprocal tariffs the president announced on April 2 and will be part of a separate national security classification under Section 232 of the Trade Expansion Act of 1962 Trump is to announce, they said.

“We are taking a look at Semiconductors and the WHOLE ELECTRONICS SUPPLY CHAIN in the upcoming National Security Tariff Investigations,” Trump wrote.

A bulletin posted by U.S. Customs and Border Protection late Friday night said the administration was exempting smartphones, computers, and other electronics from his reciprocal tariffs.

Trump did not push back Saturday night when a reporter asked for details on “exemptions.”

“I'll give you that answer on Monday. We’ll be very specific on Monday,” Trump said. “We're taking in a lot of money. As a country, we’re taking in a lot of money.”

President Donald Trump said he'll share more details on Monday on his plan for separate tariffs on semiconductor chips.

Asked about the plan by reporters aboard Air Force One on Saturday, Trump said, "We’ll be very specific on Monday. We're taking in a lot of money. As a country, we’re taking in a lot of money."

The comments came after the Trump administration announced that smartphones, computers, chips and other electronics would be exempt from the escalating tariffs Trump has imposed on other Chinese imports, which now stand at 145%.

Toy stores are among the hardest hit by President Donald Trump's escalating trade war with China as 77% of toys sold in the United States are made in China, according to the Toy Association.

Amy Rutherford, the owner of Pippin Toy Co. in Alexandria, Virginia, told ABC News that virtually everything in her store is made in China. Even the toys that are branded as "Made in USA" are actually made with parts from China.

The price of a stuffed panda sold at her store will rise from $32 to $80 because of the 145% tariff on Chinese products, she said.

"If it's at an $80 panda from $32, then that makes a big difference. People aren't going to want to pay that," she warned.

"I'll be able to absorb some of it, but I certainly can't absorb 145%. That's not possible. Not even half of that is possible," Rutherford added.

She said there are not enough toys made in America to fill her store with the variety she's currently selling.

Rutherford said she is trying to conserve her store's budget but added that she is concerned she may have to lay off workers in the future.
