HS Code for Sodium cyanide

Sodium cyanide is classified under HS code 2837.11. This classification falls within Chapter 28 of the Harmonized System, which encompasses inorganic chemicals and precious metal compounds. Heading 2837 is dedicated to cyanides, cyanide oxides, and complex cyanides. The subheading 2837.11 specifically identifies the sodium salt of hydrocyanic acid. The classification is straightforward because sodium cyanide is a distinct inorganic chemical compound. It is most commonly found in solid form as white, water-soluble briquettes or powder. Its classification is driven by its chemical composition rather than its application, which is predominantly in the mining industry for gold and silver extraction via the cyanidation process. Even when used in electroplating or chemical synthesis, the pure or technical grade substance remains under this specific code. The Harmonized System prioritizes the chemical identity of inorganic salts in Chapter 28 over their functional use in other sectors, provided they are not formulated into retail-ready preparations.

Products Included

• Solid sodium cyanide briquettes
• Sodium cyanide granules or powder
• Technical grade sodium cyanide for mining
• Aqueous solutions of sodium cyanide (pure)
• Sodium cyanide for electroplating baths

Common Misclassification

Sodium cyanide is often confused with other cyanides classified under 2837.19, such as potassium cyanide or calcium cyanide. While they share similar toxicological profiles and industrial uses, the HS system requires specific identification of the sodium salt. Another common misclassification occurs with HS code 3808.99, which covers rodenticides and other pesticides. If sodium cyanide is prepared and packaged specifically for use as a pest control agent, it may move to Chapter 38. However, bulk industrial shipments must be declared under 2837.11. It should also not be confused with complex cyanides like sodium ferrocyanide, which is classified under 2837.20.

FAQ

What is the HS code for Sodium cyanide?

The specific HS code for sodium cyanide is 2837.11, located within the chapter for inorganic chemicals.

Are there special regulations for exporting sodium cyanide?

Yes, sodium cyanide is a highly regulated substance due to its extreme toxicity and potential for misuse. It is often subject to the Rotterdam Convention and requires strict export permits, specialized hazardous material (Class 6.1) packaging, and comprehensive Material Safety Data Sheets (MSDS) for all international shipments.
