The geographical signs of pistachio and plaster produced in Semnan Province of Iran have been registered internationally and domestically.
Mehdi Mirku, the head of training, research, and technology administration of the General Directorate of the Ministry of Industry, Mine and Trade in Semnan Province, said on Monday that the two products of the province have been registered internationally and that the Organization for the Registration of Deeds and Property issued a certificate in this respect.
According to the official, Semnan's plaster mines have been highlighted because of their purity and white color.
The pistachio from Damghan in Semnan Province is also famous because of its taste and shape, he said, adding that the pistachio is preferred due to its early fruiting in comparison to the pistachio from Kerman and Rafsanjan.
