Labour has adopted all of the International Holocaust Remembrance Alliance examples of antisemitism, a party spokesman said.
The party will now incorporate all 11 examples into its code of conduct after not including them all back in July.
Labour party members met on Tuesday afternoon to discuss the IHRA examples at its National Executive Committee.
In a statement, the Labour party said: "The NEC has today adopted all of the IHRA (the International Holocaust Remembrance Alliance) examples of antisemitism, in addition to the IHRA definition which Labour adopted in 2016, alongside a statement which ensures this will not in any way undermine freedom of expression on Israel or the rights of Palestinians.
"The NEC welcomed Jeremy Corbyn's statement to the meeting about action against antisemitism, solidarity with the Jewish community and protection of Palestinian rights, as an important contribution to the consultation on Labour's code of conduct."
The party is also expected to publish a statement aimed at protecting free speech.

Arriving at the meeting on Tuesday afernoon, Chris Williamson said: “Some people have said Labour isn’t accepting, or is dragging its feet about accepting the IHRA definition. The Labour party has accepted the IHRA definition in full, the only issue really is the working examples, which were never really drawn up to act as a code in the way it’s being used now. They were drawn up many years ago to help gather statistics on antisemitism.
Valerie Cox, a pro-IHRA campaigner said that Jeremy Corbyn was “destroying the Labour Party” despite her husband, a former Labour MP, telling her in the 1970s that Mr Corbyn was “a complete non-entity”.
