U.S. President Joe Biden's team is still looking at its options on cutting tariffs on Chinese imports to ease inflation, the White House said Tuesday, even as industry requests to maintain the duties have mounted.

More than 400 requests to keep tariffs in place on Chinese goods had been submitted to the office of the U.S. Trade Representative (USTR) as of late Tuesday, complicating Biden's decision making.

Among these are a committee of 24 labor unions from the AFL-CIO to the Air Line Pilots Association, which has requested that all of the "Section 301" tariffs imposed by former President Donald Trump continue, covering some $370 billion in Chinese imports.
