Import Tips & Compliance
• Include certificates of analysis showing silver content >28% of cathode material per tariff definition
• Segregate from lithium batteries during transport; silver oxide cells have different UN numbers (UN3090 vs UN3480)
• Watch for anti-dumping duties on certain Asian silver oxide cells; check Commerce Department scopes
