Peru - why aren't we allowed to mail used clothing to someone in Peru, from Canada?

It could be for the same reason as Nigeria. I have been attempting business in Nigeria, and it is impossible to send any type of material there. It is to do with narcotics. I am not sure of the exact reason but certainly in Nigeria it is too do with the fact that drugs can be smuggled in, in amongst the fabric. I would guess that this maybe the same for peru, I doubt it is just from Canada, it is most likely for the entire world. The best way to do it would be to speak to the Peruvian border control and explain to them what you want to do and maybe they will have a solution or speak to a charity organization in Peru and maybe they could help arrange it for you.

The only way you can send used clothing to Peru by mail is to send it as "unaccompanied baggage" in which case someone who is traveling to Peru must be the sender, then once he gets here, he's the only one who can claim it.

Why they forbid it? Because for many years this was used as a profitable business that was disloyal to the clothing stores. It doesn't quite fit in the description of dumping, because we're not talking about brand new items, but indeed it has the same effect on commerce.

Dumping: Selling goods abroad at a price below that charged in the domestic market

I send used clothing and plush toys to Perú with passengers or with airline crew members. Since they travel for cheap they are most of the time really happy because 80 dollars will help them cover their round trip cost to come here. That is what I offer for taking one suitcase to Perú.

your family member wants to help? cool!!, but tell him DON'T BE CHEAP and send new clothing !!!

Why they don't permit sending used clothing? ... dumping, that is the reason. The only way any civilized country would accept used items is if they go through a recognized donation agency, otherwise, it is dumping.

HAVE NO IDEA...YOU SHOULD ASK YOUR LOCAL POST OFFICE OR SOMETHING WHY NOT??...
