Lithium batteries are regulated dangerous goods requiring special logistics. Shipping is available to the US, Canada, Australia and most European countries only. For buyers from other countries, please inquire before placing an order.
2. For certain countries, buyers are required to handle customs clearance at the airport or port by themselves. Please ensure you are capable of doing so, and if you have any queries, feel free to contact me before making the purchase.
3. For batteries purchased in bulk, I ensure the time interval between the production date and the shipping date is no more than 180 days; for non-bulk battery purchases, the interval is capped at 360 days – this is, of course, the worst-case scenario.
