First & foremost we would need to know where you're trying to get batteries & vape stuff shipped to / imported into.
A few countries ban all vaping gear, some have strict regulations on importing nicotine & L ion batteries, some allow x amount of nicotine but ban consumer level importation of L ion batteries.
Some allow importing as long as you fill out the appropriate paper work and ship in accordance with IDG guidelines, ( requires documentation, specific labeling and a pre approval process )
Some have minimum quantity requirements like 12 pieces, 1 case, 4 cases, 44lbs etc...
There are a few where getting a semi decent IMR/hybrid loose battery (18350 ~ 18650) is very close to impossible, but you can buy vaping power devices with built in batteries.
There must be a reason you keep asking about gear & batteries from iffy obscure low quality sources.
