Israel has said it hopes Poland would still amend a bill that would impose jail terms for suggesting the country was complicit in the Holocaust.
Poland's president said he would sign it into law, defying criticism from Israel, the United States and activists.
Israel's foreign ministry said in a statement on Twitter that Israel hoped that before it was finalised "it will be possible to agree on introducing changes and amendments to the law".
Earlier, Andrzej Duda said in a televised address the legislation would ensure Poland's "dignity and historical truth".
Poland's right-wing government says the law is needed to protect the reputation of its citizens and make sure they are recognised as victims not perpetrators of Nazi aggression during World War II.
Israel has said the law would curb free speech, criminalise basic historical facts and stop any discussion on the role that some Poles played in Nazi crimes.
Activists say the passage of the bill has encouraged a rise in anti-Semitism.
More than three million of Poland's 3.2 million Jews were murdered by the Nazis, accounting for about half of the Jews killed in the Holocaust.
Jews from across Europe were sent to be killed at death camps built and operated by Germans in Poland, including Auschwitz, Treblinka, Belzec and Sobibor.
The measure would impose prison sentences of up to three years for mentioning the term Polish death camps and for suggesting publicly and against the facts that the Polish nation or state was complicit in Nazi Germany's crimes.
President Duda said the bill would protect Poland's interests "so that we are not being slandered as a state and as a nation", but it also takes into account the sensitivity of those for whom remembering the Holocaust is extremely important.
He added that he would ask the Constitutional Tribunal for a number of clarifications about the bill.
Those would likely be issued after it goes into effect. The legislation provides exemptions for research and art.
