Industrial Potassium Cyanide Briquettes
Industrial potassium cyanide briquettes are compressed forms of KCN designed for safe handling in mining operations, particularly for gold extraction. They are a simple cyanide of an inorganic base, potassium, and are chemically defined under Chapter 28 Note 1. The briquette form does not affect classification, so they fall under tariff item 2837.19.00.
