Import Tips & Compliance
• Declare as hazardous material (UN2803) and comply with IATA/DOT shipping regulations for mercury-containing batteries
• Provide material safety data sheets (MSDS) confirming mercuric oxide content to avoid misclassification as alkaline batteries
• Check destination country restrictions on mercury content due to environmental regulations like RoHS
