Full Details

USPS prohibits mailing standalone lithium batteries internationally. Lithium batteries contained in equipment may be shipped domestically with restrictions. For international shipping, only lithium batteries installed in devices (UN 3481) under 100Wh are accepted via USPS ground services. Enforcement in United States carries fines from USD 250 to USD 10,000 under 19 USC § 1497 (failure to declare); 39 USC § 3005 (postal fraud) (typical personal cases are handled as civil infringements).

PRACTICAL ADVICE

Use private couriers (FedEx, UPS) for lithium battery shipments as they accept properly declared dangerous goods. Never ship damaged or recalled power banks.
