   Logistics for international shipments of Li-ion batteries can be complex due to strict regulations regarding hazardous materials. Ensure that your supplier is familiar with IATA regulations and can provide proper packaging and labeling. Discuss shipping options, including freight forwarders experienced in handling batteries, and factor in potential customs delays or tariffs. Planning for these logistics will help ensure timely delivery and compliance with international shipping laws.

7. How can disputes over defective products or delivery delays be effectively managed?
   To manage disputes, establish clear terms and conditions in your purchase agreement, detailing warranties, returns, and dispute resolution processes. Keep thorough records of all communications and transactions. In case of a dispute, communicate promptly with the supplier to resolve issues amicably. Consider mediation or arbitration as alternative dispute resolution methods to avoid lengthy legal processes, especially in international contexts.

8. What should I do if I encounter safety concerns with 3.7V Li-ion batteries?
   If safety concerns arise, such as swelling, leaking, or overheating batteries, immediately cease usage and contact the supplier for guidance. Document the issue with photographs and detailed descriptions to support your case. Ensure your supplier has a clear return and recall policy for defective products. Stay informed about any safety recalls or warnings issued by manufacturers and regulatory bodies to protect your business and consumers from potential hazards.
