That list was renewed in March 2017 for six months and is expected to be extended again in September.
Siemens has said the turbines were "illegally" diverted "against our will" to Crimea and that it was cutting some of its ties to Russia following revelations of the illegal shipments.
It said the turbines originally had been sold for use at the Taman power plant in southern Russia.
Siemens on July 21 said it would halt deliveries of power-generation equipment under its existing contracts with Russia's state-controlled entities "for the time being" in response to the revelations.
