WASHINGTON — U.S. Trade Representative Jamieson Greer said Friday that there were no immediate semiconductor tariffs coming, according to a report, though he underscored the importance of protecting America's chip sector.

Greer made the remarks at Micron Technology's memory chip plant expansion project outside Washington, Reuters reported, apparently referring to sectoral duties on chip imports that might come after national security investigations under Section 232 of the Trade Expansion Act of 1962.

"So, having tariffs on semiconductors is really important. What's even more important than having protection for facilities like this, is making sure we do it on the right timing and in the right amount," Greer was quoted by Reuters as saying.

"There was not an immediate tariff coming," he added.
