Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alkaline chemistry instead of silver oxide
Alkaline primary button cells fall under silver oxide subheading only for actual silver oxide electrolyte systems.
If volume exceeds 300 cm³
Larger silver oxide primary cells are classified by size threshold regardless of button/coin form factor.
If marketed as rechargeable
Secondary/rechargeable lithium button cells go to Chapter 85 heading 8507, not primary cell heading 8506.

Import Tips & Compliance
• Verify battery volume does not exceed 300 cm³ and confirm silver oxide chemistry via material safety data sheets
• Include UN38.3 test reports for lithium-free primary cells; label with proper shipping names per DOT/IATA regulations
• Avoid misclassification as rechargeable cells (8507.60) which have different duty rates and testing requirements
