US President Donald Trump's sweeping new tariffs on more than 90 countries around the world have come into effect.
Moments before his deadline passed for countries to negotiate US trade deals, Trump posted on his Truth Social platform that billions of dollars were now flowing into his country as a result of his import taxes.
Trump is using tariffs to encourage jobs and manufacturing industries to return to America, among other political goals.
Separately on Wednesday, he threatened to raise the tariff on imports from India to 50%, unless that country stopped buying Russian oil. He also threatened a 100% tariff on foreign-made computer chips, to push tech firms to invest more in the US.
Trump's trade policies have been broadly aimed at reshaping the global trading system, which he sees as treating the US unfairly. One of his key pledges as he returned to the White House in January was to cut the trade deficit - the shortfall between what America buys and what it sells.
His tariffs work by charging US importers a tax on goods they buy from other countries. Those importers may pass some or all of the extra cost on to customers.
Trump has also been accused of throwing the global economy into turmoil in recent months, though markets have recently been more stable.
The overall average US tariff rate is at its highest in almost a century, thanks to a range of other industry-specific taxes affecting products such as vehicles and steel.
The duties that came into effect on Thursday were first announced in April. Many were later paused amid market turbulence, and to give other countries time to strike new trade deals with the US.
A patchwork of rates were set for different countries - and were adjusted over time by Trump, who ultimately set a negotiating deadline of 7 August.
