According to a statement from the Netherlands, the Dutch-led joint investigation team (JIT) said a BUK type missile launcher was brought into Ukraine from Russia.
"Based on the criminal investigation, we have concluded that flight MH17 was downed by a BUK missile of the series 9M83 that came from the territory of the Russian Federation," the statement read.
The investigations also showed that the missile launcher used to down MH17 -- which had been carrying 298 people -- was later taken back to Russia.
Dutch authorities had released interim findings last year, which concluded that a Russian-made BUK missile hit the ill-fated plane.
The interim investigation report, however, did not state the location from where it was fired.
The JIT said many private calls were intercepted during the investigation process and the recordings were made evidence of the findings.
Witnesses also saw the missile launcher move from Russia to Ukraine, the team added.
At the time MH17 was shot down, fierce fighting was taking place in eastern Ukraine between pro-Russian separatists and Ukrainian government troops --both sides have denied responsibility.
The Russian government had challenged the earlier findings, with the makers of Buk missile systems, Almaz-Antey, saying that experiments proved that one of its missiles could not have been launched from areas under pro-Russia separatist control.
The Kuala Lumpur-bound flight MH17 from Amsterdam was shot down in the troubled Ukrainian state of Donetsk on July 17, 2014, killing all 283 passengers and 15 crew on board.
Of the causalities from MH17, 193 were nationals of the Netherlands, 43 of Malaysia and 27 of Australia.
