The U.S. Commerce Department said on Thursday it had completed its probe into whether imports of certain steel products threatened U.S. national security and sent its conclusions to President Donald Trump.
In a statement that offered no indication of the investigation's findings, the Commerce Department said Trump now has 90 days to decide "on any potential action."
The probe could lead to broad tariffs or import quotas.
White House Deputy Press Secretary Lindsay Walters said in a brief statement that Trump would announce his decision "at the appropriate time."
Trump opened the "Section 232" investigation in April. Commerce Secretary Wilbur Ross set an internal deadline of end-June for announcing his recommendations, but an announcement was delayed for a G20 summit and bilateral talks with China in July.
Trump said later in July that a final decision could wait until other top priority issues on his agenda were addressed, including healthcare and taxes.
