On 30 December 2015, Rosaviatsiya certified the Mi-38, completing the testing and certification program and allowing for the delivery of the first production model. Certification was based on the third and fourth flight-test prototypes with Klimov TV7-117V engines. In July 2017, a contract for delivery of first two serial Mi-38s to the Russian Defence Ministry was signed. The Kazan Helicopters plant launched the serial production of the helicopter on 10 January 2018. In total, the Russian Defence Ministry planned to purchase about 15 helicopters until 2020. On 23 November 2018, military variant, Mi-38T, performed its maiden flight. The new variant was developed to meet the Russian MoD's new requirements for the helicopter and due to international sanctions imposed on Russia, all of its components, including engines and avionics, are Russian-made. Deputy Managing Director at Kazan Helicopters Vadim Ligai stated that the Mi-38 can now carry up to 40 passengers. The Russian Defence Ministry took delivery of the first two serial Mi-38s in December 2019.

The RF Defense Ministry ordered 2 more Mi-38s in increased comfort cabin configuration in August 2020 and the Ministry of Emergency Situations ordered 9 in August 2021.
