Thread: Bring stuff in luggage from the US/Canada

Sorry I know there is a million threads at the moment on such topics, maybe we could make some sticky threads lol.

But anyway, I have a friend who is travelling to the US later this year and he was thinking about bringing back some brass, projectiles and other bits and bobs.
I know that gun parts need and export permit if you want to take it out of the country, and an import permit to come into the NZ, but does projectiles and brass need anything to get out of the US? I'm possibly going to Canada next year so am wondering a similar thing.

Actually while I'm at it does anyone know if you try to bring stuff out of Canada or the United States whether these things are restricted, or do they not care what leaves in your luggage?

Thanks
