Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If gaseous hydrogen cyanide or simple cyanogen acids
Chapter note 2(a) places hydrogen cyanide and simple cyanogen acids in 2811, distinct from metal salt cyanides.
If containing cyanogen or cyanogen halides
Heading 2853 covers cyanogen and derivatives per Chapter notes; pure KCN remains in 2837.
If sold as bulk prepackaged for lab use with diluents
Prepackaged chemical mixtures for retail/lab fall in 3824; pure bulk KCN stays chemically defined in Chapter 28.

Import Tips & Compliance
• Include Material Safety Data Sheets (MSDS) and cyanide handling certifications in import docs; subject to FIFRA if pesticide-related
• Use UN-approved drums with inner liners; avoid common error of insufficient ventilation in storage declarations
• Register with Cybersecurity and Infrastructure Security Agency (CISA) for chemical security; track via CERS for California importers
