U.S. exports of cyanides, cyanide oxides, and complex cyanides (SITC 52381) totaled $14.2M in July 2026.
Importers of Cyanides, Cyanide Oxides, and Complex Cyanides paid $120K in duties in July 2026 — an effective duty rate of 9.5% on $1.3M in dutiable value, based on actual customs collections rather than the published tariff schedule. Cyanides, Cyanide Oxides, and Complex Cyanides imports of $1.4M in July 2026 ran 89% above the year-to-date monthly average of $718K.
Last updated: July 2026 dataSodium cyanide, potassium cyanide, and complex cyanide salts are tightly regulated industrial chemicals whose primary commercial applications span gold and silver leaching in mining, electroplating baths, and specialty chemical synthesis. Import shipments are subject to EPA and OSHA hazardous-material requirements, and exporters must comply with the Rotterdam Convention's prior informed consent procedure for certain cyanide compounds. Classification precision matters here because simple cyanides, cyanide oxides, and coordination-complex cyanides (such as ferrocyanides and ferricyanides) each occupy distinct tariff positions with different duty treatment.

Simple cyanides (e.g., sodium or potassium cyanide) contain a single metal-CN bond, while complex cyanides such as ferrocyanides and ferricyanides are coordination compounds where cyanide ligands surround a central metal ion. This structural distinction drives separate tariff-line placement and can affect duty rates, so importers should confirm the chemical specification with their customs broker before filing.
Sodium cyanide is classified as an extremely hazardous substance under EPA regulations and requires proper DOT hazmat labeling and packaging. Importers must also ensure compliance with TSCA inventory requirements and, depending on origin, may need to address Rotterdam Convention prior-informed-consent documentation for certain cyanide compounds.
