President Donald Trump said “no extensions will be granted” to his Aug. 1 tariff deadline in a Tuesday social media post, the latest bit of uncertainty over when his tariffs will go into effect.

“There has been no change to this date, and there will be no change,” Trump posted Tuesday morning to Truth Social, the social media website he owns. “In other words, all money will be due and payable starting AUGUST 1, 2025 – No extensions will be granted.”

Trump has repeatedly set tariff deadlines in his global trade war over the last several months, only to walk them back at the last minute.

Trump even told reporters Monday that the Aug. 1 deadline was “firm, but not 100 percent firm.”

“Because if they call up and say ‘we’d like to do it a different way,’ I’d be open to that,” he said.

The Trump administration has started to send out letters to trading partners — which were also posted to Truth Social — on Monday, where Trump also offered to “consider an adjustment.”

“These Tariffs may be modified, upward or downward, depending on our relationship with your Country,” he said. “You will never be disappointed with the United States of America.”

Fourteen nations received tariff letters Monday. Trump indicated more countries will receive letters in the coming days and threatened higher tariffs for any nation that implemented retaliatory tariffs.

The Aug. 1 deadline was the result of an extension of a 90-day pause on previously announced “reciprocal” tariffs.

The president has waffled on tariff deadlines over the course of his second term, extending once-firm deadlines and threatening higher tariffs for those nations who do not reach trade deals.
