Enforcement will remain “an ongoing process” as behaviour continues to evolve on the app, TikTok said.
The move comes as social media firms face growing calls to do more to tackle hate and misinformation, with Facebook and Twitter both updating their policies in recent weeks.
Karen Pollock, chief executive of the Holocaust Educational Trust, said companies have a responsibility to counter hate.
“We welcome today’s developments and look forward to seeing these policies implemented to ensure that Holocaust denial, distortion and antisemitism are not welcomed, shared or supported on TikTok.
“We will continue to work with TikTok and other social media platforms to make sure this is the case,” she said.
Danny Stone, head of the Antisemitism Policy Trust, said TikTok has a “large and growing audience” and an “equally big responsibility” to ensure its platform is not used to spread hate.
He said the charity was “pleased that the company is seeking to deepen its understanding and broaden its policies” against antisemitism and other forms of racism.
“We look forward to emerging platforms taking similar such actions,” he added.
Tiktok reported last month it had more than 100 million monthly active users across Europe.
