HS-4 · Heading
2837 — Cyanides, cyanide oxides and complex cyanides
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-4 2837 when importing or exporting cyanides, such as sodium cyanide used in gold extraction, or complex cyanides like those used in electroplating. Understanding the specific subheading is crucial for compliance and accurate duty assessment.
When deciding between HS-6 283711 and HS-6 283719, consider the chemical composition. If your shipment includes sodium cyanide, classify it under 283711. For other cyanides, such as potassium cyanide, use 283719. This distinction affects tariff rates and regulatory requirements.
For complex cyanides, use HS-6 283720. These are typically used in specialized industrial applications, such as in the production of certain dyes or as intermediates in chemical synthesis. Ensure you have the correct documentation to support your classification.
