The most restrictive portion of the package, which is expected to be challenged in court, makes abortion illegal once a fetal heartbeat is "detectable," the New York Times reported.
Fetal heartbeats can be heard via ultrasound as early as the sixth week of pregnancy, the newspaper added.
Gov. Jack Dalrymple, a Republican, signed a total of three bills passed by the Republican-controlled North Dakota legislature, but legal experts have asserted that the package violates the basic tenets of Roe v. Wade, the historical ruling by the U.S. Supreme Court that found abortions could be performed until the fetus would theoretically be able to survive outside the womb, roughly 24 weeks into a pregnancy.
"Although the likelihood of this measure surviving a court challenge remains in question, this bill is nevertheless a legitimate attempt by a state legislature to discover the boundaries of Roe v. Wade," Dalrymple said in a statement.
The three bills are scheduled to take effect Aug. 1, unless a legal challenge is filed, the Times reported.
The Center for Reproductive Rights, in New York City, promptly condemned the new laws and said it would file a challenge, according to the Times.
The signings follow passage last week of a proposed amendment to the North Dakota Constitution that would claim life begins at conception. The so-called "personhood measure" will go on the ballot next year. Such measures have previously been voted down in Mississippi and Colorado, the Times reported.
Measures to ban abortions when fetal heartbeats are detected are under consideration in several other states, including Kansas and Ohio, the Times reported.
Groups including National Right to Life, Americans United for Life and the Roman Catholic Church have not supported fetal heartbeat proposals, saying they could be counterproductive unless the makeup of the Supreme Court changed dramatically.
