Last updated: July 2026 dataPotassium cyanide and other non-sodium cyanide salts serve specialized roles in electroplating, pharmaceutical synthesis, and precious-metal refining. The US schedule separates potassium cyanide (2837190110) from other cyanides and cyanide oxides not elsewhere specified (2837190120 and 2837190125), a distinction that matters for both duty calculation and end-use tracking. Germany leads import supply, with South Korea and the Czech Republic also notable sources, reflecting concentrated production among established industrial-chemical exporters.

Potassium cyanide (KCN) classifies under 2837190110 within heading 283719, while sodium cyanide (NaCN) falls under the separate heading 283711 (line 2837110000). The distinction is based on the alkali metal cation — potassium versus sodium — and the two products are not interchangeable for classification. Importers should ensure the correct cation is identified on the commercial invoice and entry documentation.
Like sodium cyanide, potassium cyanide imports require an EPA TSCA certification at entry. Shipments must also be accompanied by a Safety Data Sheet (SDS) meeting OSHA Hazard Communication Standards. Depending on the importing facility's storage quantities, DHS CFATS reporting obligations may also apply. A licensed customs broker with hazardous-chemical experience should be engaged for these shipments.
