Import Tips & Compliance

• Provide electrochemical data confirming silver oxide (Ag2O) cathode to avoid reclassification to alkaline primary cells

• Package in original retail blister packs with child-resistant features to meet CPSC safety standards

• Declare exact battery dimensions to confirm ≤300 cm³ volume limit; measure external housing precisely
