No. Airport security agencies will treat all military ordinances, including deactivated or imitation, as active.
Deactivated devices (e.g. empty shells) where the explosives have been removed, and imitations are also prohibited.
Military ordinances are weapons developed for the military, and include grenades, mines, mortars, and smoke canisters.
Military ordinances are not lawfully permitted to be possessed by members of the public.
All military ordinances are strictly forbidden from carriage on an aircraft.
Note: We do not recommend passengers take toy explosives (e.g., grenades) when they travel as this will result in your bag being searched and may result in the toy removed. The carriage of toy explosives will also create delays as your bag will likely need to be opened to verify that the item is safe.
Military ordinances are weapons developed for the military, and include grenades, mines, mortars and smoke canisters.
