Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in therapeutic dosage presentation
Chapter 30 medicaments take precedence over pure hormone classification.
If classified by peptide/protein content
Protamine as main characteristic could shift to Chapter 35 peptides if not insulin-primary.

Import Tips & Compliance
• Protamine-insulin complex stability requires continuous 2-8°C; validate suspension integrity
• Declare as insulin-protamine complex, not separate protein mixture
• Pure hormone derivative status preserved despite complexing agent
