What is not permitted?
Firearms:
Firearms cannot be listed on eBay.co.uk or eBay.ie. In addition UK and Irish residents cannot list firearms on any eBay site worldwide. Firearms include all component parts of a firearm, sporting, collectible, curio & relic, signalling pistols, and antique firearms, regardless of their capability to fire a shot. Any item that is designed to discharge any shot, bullet or other missile is covered by this ban, regardless of that item's present ability to fire. Replica or imitation firearms may also not be listed on eBay.
Related items:
Other firearms related items that are not permitted on eBay include BB guns, air guns, air pistols, paintball guns, silencers, converters (any item which can convert a firearm to have automatic capability), kits (any kit that can be used to create a firearm), high voltage electric stunning devices (for example, 'tazers' ), flares, flare launchers, flare guns, and the receivers for flare guns. Illegal components, such as silencers, converters (to convert a firearm to have automatic capability), and short barrels are prohibited. Weapons that discharge noxious substances, liquids or gas, including tear gas or pepper spray dispensers, are also prohibited and may not be listed on eBay.
Ammunition:
Magazines and live, inert, and blank ammunition, as well as any component used to make up an actual round of ammunition, such as lead bullets, brass/casings, shells, primers and gunpowder cannot be listed. Blank ammunition is not allowed under our fireworks policy. In addition any bullet reloading device or any equipment used to manufacture ammunition is not permitted.
Ordnance and grenades:
Ordnance, or items which appear to be ordnance (military weaponry, ammunition and related parts), and grenades cannot be listed, even if the listing states that the item is 'unserviceable' or has been made safe in any way. This also applies to items such as relics, curios, memorabilia, or display items which are or appear to be deactivated. Examples include: any type of grenade, rocket, shell, launcher or propulsion equipment or similar items.
If your listing breaches any part of this policy your account may be immediately suspended.
