Is it legal to mail a vape to a friend?
No. Electronic nicotine delivery systems are nonmailable for private senders, and USPS applies the rule to devices, parts, pods and liquids alike, with or without nicotine inside.
Can a business ship vaping products?
Only a narrow set of authorized shippers qualifies for the postal exceptions, and the process sits far outside consumer checkout tools. FedEx refuses tobacco and vape freight even from licensed senders, and SMKlog offers no path for these items at all.
Does zero-nicotine vape juice ship differently?
It does not. The ENDS definition turns on the device and liquid type rather than nicotine content, so flavored zero-nicotine liquid is treated the same as the strongest pod.
Can I ship a vape case or a humidor?
Yes. Empty accessories carry no tobacco and no nicotine: cases, stands, organizers and humidors all quote as ordinary goods when described accurately.
