Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as hydrogen cyanide solution with sodium
Simple cyanogen acids like HCN are classified in 2811, not their metal salts.
If converted to sodium carbonate form
Carbonates of sodium fall under 2836 per chapter exclusions.
If for laboratory reagent grade with additives
Prep kits or diluted forms become 'chemical preparations' under 3824.
