HS-6 · Subheading
283720
Complex cyanides
Heading 2837 — Cyanides, cyanide oxides and complex cyanides
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-6 283720 when importing or exporting complex cyanides, such as potassium gold cyanide used in electroplating. This code specifically covers compounds that contain cyanide ions in a complex form, which can be essential in various industrial applications.
Complex cyanides differ from simple cyanides like sodium cyanide, which is classified under HS-6 283710. While both contain cyanide, complex cyanides involve multiple metal ions and are often used in specialized processes, such as metal extraction or chemical synthesis.
When dealing with HS-6 283720, you may encounter products like sodium zinc cyanide or copper cyanide. These compounds are often found in the mining industry or in the production of certain chemicals, making proper classification crucial for compliance and duty assessment.
