Last updated: July 2026 dataPotassium nitrate—historically known as saltpeter—functions as a fertilizer component, a heat-transfer medium in solar energy systems, and an oxidizer in pyrotechnic and specialty glass applications. Chile dominates US import supply under this heading, reflecting its established nitrate-mining and chemical industry, with Israel and Germany also notable sources. The single tariff line 2834210000 covers all potassium nitrate regardless of grade, but importers of fertilizer-grade material should be aware of applicable EPA and state-level reporting requirements for oxidizing substances.

Potassium nitrate is classified as an oxidizer under DOT hazardous materials regulations, requiring proper labeling, packaging, and shipping documentation (including a hazardous materials declaration). These requirements apply regardless of the customs classification and must be addressed before the cargo is tendered to a carrier.
