ASML said in March it expects the Dutch regulations to affect its TWINSCAN NXT:2000i and more sophisticated models.
But the company's older DUV models, like one called the TWINSCAN NXT:1980Di, could also be kept from about six Chinese facilities by the U.S.
The new Dutch regulations will not take effect immediately, sources said, with one person expecting the effective date to be September, two months after publication.
ASML is Europe's largest chip equipment company due to its dominance in lithography, one of the central steps in the computer chip making process.
Other companies that could be impacted by the new Dutch rules include atomic layer deposition firm ASM International.
