Last updated: July 2026 dataSodium cyanide is an essential reagent in gold and silver heap-leach mining operations, and its import is tightly controlled given its acute toxicity and dual-use potential. All shipments enter under the single tariff line 2837110000, but importers must also comply with EPA Toxic Substances Control Act (TSCA) certification requirements and, in many cases, Department of Homeland Security chemical facility security regulations. Germany is the leading US supplier, with China and Japan also significant sources; origin documentation and chain-of-custody records are critical given the regulatory scrutiny applied at the port of entry.

Importers must file an EPA TSCA certification (either a positive certification that the shipment complies with TSCA, or a negative certification that it is not subject to TSCA). Additionally, facilities that store sodium cyanide above threshold quantities may fall under DHS Chemical Facility Anti-Terrorism Standards (CFATS). Some ports also require advance notification. Consulting a licensed customs broker and legal counsel familiar with chemical import compliance is strongly recommended.
Sodium cyanide imports from China may be subject to Section 301 tariffs. Importers should verify current applicability and any product-specific exclusions with a customs broker, as the Section 301 list and exclusion orders are subject to ongoing administrative review.
