Producer
Ingas (Ukraine)
Ukrainian rare gas company (Mariupol, Donetsk Oblast); was the world's largest supplier of semiconductor-grade neon before the Russian invasion of Ukraine in February 2022. Ingas produced crude neon from the Mariupol Ilyich Iron & Steel Works (one of Ukraine's largest steel plants) — a massive ASU byproduct stream that was purified to semiconductor grade (5N+ purity) for sale to chip manufacturers globally. Ingas reportedly supplied approximately 25-30% of global semiconductor-grade neon. The company's facilities in Mariupol were effectively destroyed or seized during Russia's brutal siege of Mariupol in March-April 2022 — the same siege that made Mariupol's Azovstal Steel Plant famous for the Ukrainian military's last stand. When Ingas stopped operating, a significant fraction of global semiconductor neon supply disappeared overnight. TSMC, Samsung, Intel, and other major chip manufacturers scrambled to find alternative sources.

Incident2022
Ingas LLC (Mariupol) was the world's single largest semiconductor-grade neon producer, operating from a facility at the Mariupol Ilyich Iron & Steel Works — one of Ukraine's largest Soviet-era steel complexes. In March-April 2022, Russian forces besieged Mariupol in one of the most devastating urban battles of the war: the Mariupol Ilyich plant and the nearby Azovstal Steel Works became the last Ukrainian holdouts in the city. The Ingas facility was destroyed or made inoperable during the fighting. On May 20, 2022, the last Ukrainian defenders at Azovstal surrendered. The destruction of Ingas eliminated approximately 25-30% of global semiconductor neon supply simultaneously with one of the worst humanitarian disasters of the war. Chip manufacturers who had been monitoring the battle in Mariupol for territorial and geopolitical reasons also had a direct supply chain stake in its outcome: every missile that hit the Mariupol industrial zone was potentially destroying the world's largest neon production facility.

Ingas LLC was founded in Mariupol, Donetsk Oblast, Ukraine to process the atmospheric gases separated during steel production at the Mariupol Ilyich Iron & Steel Works -- one of the largest Soviet-era steel plants, employing tens of thousands. Steel production requires large volumes of oxygen and nitrogen extracted from air; the air separation units (ASUs) that produce these gases also produce neon, krypton, and argon as byproducts. Mariupol's industrial scale meant its ASU byproduct streams were enormous -- a single large steel plant produces enough neon for significant semiconductor industry volumes. Ingas built purification technology to refine crude neon from the steel plant ASU stream to 5N+ semiconductor grade, a processing step that requires specialized gas separation and cryogenic technology. Pre-2022, Ingas and Cryoin (also Mariupol-based) together accounted for approximately 45-50% of global semiconductor-grade neon supply -- from a single Ukrainian port city on the Azov Sea. The February 2022 Russian invasion targeted Mariupol as a strategic objective to create a land corridor between Russia and Crimea; the destruction of Ingas was a collision between geopolitical strategy and supply chain geography.
