Import Tips
• Label batteries clearly with chemistry type (silver oxide) and capacity to prevent reclassification during customs exam
• Package in child-resistant blister packs if marketed for consumer sale to meet CPSC requirements
• Confirm non-rechargeable status; rechargeable silver-zinc cells would classify differently under 8507
