Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If prepared as a vaccine rather than pure toxin
Vaccines for human use against ricin fall under specific vaccine subheadings in 3002.11, distinct from unmixed toxins.
If imported as a crude chemical extract without therapeutic labeling
Unmodified plant alkaloids like ricin may classify under Chapter 29 as organic chemicals if not presented for immunological use.
If for bulk castor seeds from which ricin is extracted domestically
Plants used in extracting ricin (e.g., castor beans) are under Chapter 12 for medicinal plants, not purified toxins.

Import Tips & Compliance
• Obtain CDC Select Agent permit and ensure all import documentation specifies research-only use to comply with US biosafety regulations
• Provide certificates of analysis confirming purity and absence of live contaminants; common pitfall is inadequate chain-of-custody records
• Declare exact quantity and intended prophylactic purpose to avoid reclassification as a hazardous waste under different chapters
