The Hwasong-12 was first revealed to the international community in a military parade on 15 April 2017 celebrating the Day of the Sun which is the birth anniversary of North Korea's founding president, Kim Il Sung, although the first test took place on 4 April 2017. The first successful test-fire of Hwasong-12 occurred on 14 May 2017.

In October 2016, North Korea launched two ballistic missiles but failed. Initially, these launches were thought to be Hwasong-10, however, it is possible that the missiles used in the tests could be Hwasong-12. Since North Korea did not issue a press release mentioning these test-fires, it is hard to identify the missile used in these launches. The first test-fire of Hwasong-12 occurred on 4 April 2017. As North Korea did not publish information about the launch, the missile was misreported as a Scud variant. It received the United States's designation of KN-17. On 15 April 2017, the Hwasong-12 was first revealed to the world during a military parade. The following day, a test-fire of Hwasong-12 took place. However, the launch also failed. Another failed test flight also occurred on 29 April 2017. Hwasong-12 had the first successful test flight on 14 May 2017. Further test-fires occurred on 28 August and 15 September 2017. Afterward, North Korea displayed Hwasong-12 during military parades on 8 February 2018 and 10 October 2020. A further test-fire occurred on 30 January 2022.

In the press release about the January 2022 test, North Korea confirmed that the test was for evaluating the quality of serial-produced Hwasong-12 missiles. In January 2023, Korean Central Television published undated images of Kim Jong Un inspecting mass-produced Hwasong-12 missiles, with an image showing he and his daughter Kim Ju Ae assessing 26 Hwasong-12 missiles without warheads.

American astronomer and astrophysicist Jonathan McDowell claimed that Hwasong-12 was used for two failed tests on 15 October 2016 and 20 October 2016.

On the morning of 27 September 2021, a Hwasong-8 missile was launched in Ryongrim County. Reportedly, the missile was fitted with a hypersonic glide vehicle, which would achieve hypersonic speed. Ankit Panda, a senior fellow at the Carnegie Endowment for International Peace, stated that the new missile looked like the booster of Hwasong-12 upon inspection of the sole image of the missile, but more images would be needed to confirm it. This was one of the five 'most important' weapons laid out in a five year plan in the 8th Congress of the Workers' Party of Korea, where the development of the missile was reported to have already been completed. State media of North Korea described it as a weapon of great strategic significance. The missile apparently flew on a depressed trajectory, reaching an apogee of and a range of, although it is likely that a part of the missile's path would have been untraceable with radar due to its ability to maneuver. The test reportedly confirmed its navigational control and stability, as well as the guiding manoeuvrability and flight characteristics of the detached hypersonic gliding warhead. However, the missile allegedly failed to actually achieve hypersonic flight, with South Korean intelligence determining it only reached Mach 2.5-3, whereas hypersonic weapons are considered to travel at a speed of at least Mach although actual data on the flight was not publicly released. The South Korea Joint Chiefs of Staff (JCS) assessed that the Hwasong-8 was at an early stage of development and would take a "considerable period of time" until it could be deployed in combat. North Korea also stated that the missile was launched through "ampulization," where the liquid fuel is sealed in the launch canister. This allows the fuel to be stored for years and eliminates the need to conduct fueling before launch, reducing preparation time needed before firing, although the JCS still claimed a 'significant amount of time' was needed to deploy the missile.

Hwasong-8 has a version fitted with maneuverable reentry vehicle (MaRV). Its official designation may be Hwasong-12A, but it is not confirmed. The missile is also called as Hypersonic Missile Type 2 under South Korean naming convention. The MaRV is carried by a shortened Hwasong-12 booster. It was test-fired two times, on 5 January 2022 and 11 January 2022.

At 07:23 a.m. Pyongyang Standard Time on 4 October 2022, North Korea launched a ballistic missile from Mupyong-ni Arms Factory, Jagang Province. The missile overflew the Japan's Aomori Prefecture, flew for 21 minutes with a maximum speed of Mach, reached apogee and landed away in the Pacific Ocean, east of Japan. According to the Korean Central News Agency's statement on 10 October 2022, the Kim Jong Un-supervised launch was a part of a missile launch campaign occurred between 25 September and 9 October. The missile, fired to "send more powerful and clear warning to the enemies", was a "new-type ground-to-ground intermediate-range ballistic missile", with the official designation remaining undisclosed. Photos showed the missile with a different engine configuration and thrust-vector control system, differently shaped and possibly shorter nosecone or reentry vehicle, and possibly slightly longer second stage, so it is unknown if the test was of a "new-type" IRBM or modified Hwasong-12. This version demonstrated the ability to deliver an almost 20% greater payload than previous Hwasong-12 missiles. It is possible that the image of this test was manipulated.

North Korea displayed several Hwasong-12B missiles at the 27 July 2023 military parade. It is possible that the Hwasong-12B was renamed from Hwasong-8. The hypersonic glide vehicle of Hwasong-12B is mounted on a shortened Hwasong-12 booster.
