The Bill, which could trigger the rare step of barring a company from operating in the US market, passed the Senate by a 79-18 vote three days after it cleared the House of Representatives with strong bipartisan support.
Biden has stated he will sign the legislation.
He reiterated his concerns about TikTok in a rare telephone conversation with Chinese President Xi Jinping early this month.
TikTok complained after Saturday’s House vote, saying it was “unfortunate” that lawmakers sought to “jam through a ban Bill that would trample the free speech rights of 170 million Americans, devastate seven million businesses, and shutter a platform that contributes US$24 billion to the US economy, annually”.
Under the Bill, ByteDance would have to sell the app within a year or be excluded from Apple and Google’s app stores in the United States.
Steven Mnuchin, who served as US treasury secretary under Biden’s predecessor Donald Trump, has said he is interested in acquiring TikTok and has assembled a group of investors.
TikTok for years has been in the crosshairs of American authorities, who say the platform allows Beijing to snoop on users in the United States. But a ban could trigger lawsuits.
The Bill passed by Congress gives the US president the authority to designate other applications as a threat to national security if they are controlled by a country deemed hostile.
Elon Musk, the billionaire owner of X, formerly Twitter, came out Friday against banning TikTok, saying “doing so would be contrary to freedom of speech and expression”.
