President Trump's 10% global tariff expires before the end of the week, but the U.S. trade chief says he isn't focused on a particular timeline to implement the duties he has planned to replace them.

In February, Trump imposed a 10% global tariff to replace tariffs thrown out by the Supreme Court. That tariff is limited to 150 days, which means it will expire early Friday. U.S. Trade Representative Jamieson Greer has proposed a set of duties based on forced labor concerns to replace the expiring tariffs, but he declined to say whether they would be finalized by the Friday deadline.

"I have to talk to the president and he has to sign a directive to me, and that kind of thing," Greer told reporters about his replacement tariffs. "We're not focused on any particular timeline. We're focused on fulfilling the legal and statutory requirements."

If Greer's forced labor tariffs aren't ready in time, he has previously floated re-upping the temporary tariff, arguing that the underlying statute requires them to expire after 150 days, but doesn't say if they can be reimposed after. He declined to say whether that option is still on the table if his forced labor tariffs aren't ready in time.

"You all are going to have to stay tuned," Greer said, "and you're gonna be busy over the next few days."
