Poongsan Corporation

Poongsan Corporation was founded in 1968 and built its business on a combination that looks unusual until you understand the materials science behind it: copper processing and ammunition manufacturing, both of which depend on the same metallurgical base. The company's non-ferrous metal processing arm remains its largest by revenue, producing copper and copper-alloy sheet, strip, rod, bar, and wire used across electronics, construction, and automotive supply chains, along with coin blanks that Poongsan supplies to central banks and mints in dozens of countries, including commemorative and bullion coin blanks. That metals expertise feeds directly into the defense business, since cartridge cases, bullet jackets, and rotating bands are all copper-alloy components requiring the same forming and forging know-how the company applies to its commercial metals work. On the ammunition side, Poongsan is South Korea's principal supplier of conventional ammunition to its own armed forces, producing rounds for tank guns, howitzers, mortars, anti-aircraft guns, and naval guns, along with the components that go into them: primers, fuses, projectile bodies, tungsten penetrators, and propellant chemicals including nitrocellulose and nitroglycerine manufactured in-house.

It also produces fuses for naval ammunition, mortar shells, and multiple-launch rocket systems, giving it a role across nearly every artillery-adjacent munition type in Korean service. Its commercial and export ammunition business trades under the PMC brand, a fixture in the US sporting and competition ammunition market alongside its military production, and the company has separately supplied precision-forged components, including turbine blades, to aircraft engine manufacturers. Poongsan's ammunition plants have become geopolitically significant in recent years as South Korea has emerged as a major supplier of artillery shells to countries backing Ukraine, with Poongsan's production capacity central to that surge in exports. The company is publicly traded on the Korea Exchange, and its defense-ammunition division has been the subject of restructuring discussions within South Korea's defense industry as larger conglomerates look to consolidate munitions production, though Poongsan continues to operate as an independent, separately listed company.

Between its metals business and its shells, Poongsan occupies a narrow but strategically important niche: it is one of the few companies anywhere that controls both the raw-material metallurgy and the finished-munitions manufacturing for conventional artillery ammunition end to end. That vertical integration has become a genuine strategic asset as Western militaries and Ukraine's backers have run short of 155mm shell production capacity, and South Korea's ability to surge output has repeatedly drawn on Poongsan's plants even when the shells themselves moved to end users through third-party transfers rather than direct Poongsan sales.
