Military-Civilian Ammunition Supply Chains Share Chokepoints That Cause Cascading Shortages

The military and civilian ammunition markets in the United States are not separate supply chains; they share the same upstream inputs of nitrocellulose, smokeless powder, primers, brass, and lead. When military demand surges, it directly starves the civilian market. In May 2024, Alliant Powders suspended all commercial smokeless powder shipments because the sole domestic nitrocellulose producer at Radford was fully allocated to military contracts. Powder costs rose approximately 15 percent in 2025, and major ammunition brands implemented price hikes of 3 to 12 percent starting in early 2026. This matters because the civilian ammunition market serves not just recreational shooters but law enforcement agencies, federal agencies, private security companies, and the 20+ million Americans who purchased firearms for self-defense between 2020 and 2024. When the shared supply chain tightens, police departments compete with the military and civilian buyers for the same primer and powder allocations. During the 2020-2022 shortage, some departments reduced training ammunition by 50 percent or more, directly degrading officer readiness and public safety. Tariffs compound the problem. In 2025-2026, tariffs on imported brass and copper increased ammunition input costs by 8 to 15 percent, while simultaneously choking off imports that had previously provided a relief valve during domestic shortages. The U.S. imports significant quantities of commercial ammunition from countries like Italy (Fiocchi), Czech Republic (Sellier & Bellot), and Serbia (Prvi Partizan), and tariffs on these finished goods further restricted supply. The structural reason the supply chains are intertwined is economic: it would be prohibitively expensive to maintain separate military and civilian production infrastructure for identical chemical and metallurgical inputs. The same nitrocellulose goes into both military propellant charges and commercial hunting cartridges. The same brass alloys feed both 5.56 NATO and .223 Remington. No policy mechanism exists to manage the allocation between military and civilian demand during a surge, so the military's contracting power simply outbids the commercial market, and civilians absorb the shortage.
