Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If a double or complex salt with another metal
Chapter notes state double or complex salts of cyanides are classified in heading 2842, not simple cyanides.
If mixed with organic stabilizers or formulated as a solution for retail/industrial prep
Mixtures not chemically defined as pure cyanides fall under 'other chemical preparations' in 3824; excludes pure compounds of Chapter 28.
If calcium cyanamide derivative used as fertilizer
Chapter exclusions note calcium cyanamide falls in Chapter 31; other metal cyanamides may shift based on agricultural use.

Import Tips & Compliance
• Obtain EPA TSCA pre-manufacture notice and comply with Toxic Substances Control Act; potassium cyanide is a listed hazardous substance
• Ship as dangerous goods under UN 1680 Class 6.1; require proper DOT/IMDG labeling, packaging, and carrier certification
• Verify end-user certificates to prevent diversion; common pitfalls include inadequate spill response plans and missing RCRA waste manifests
