In general all packages sent from the US are subject to duty charges. These charges may be avoided if the sender clearly marks packages "Articles usagés pour étudiants." The package should also be declared as a gift on the small green customs sticker.

In either case, the value of a package's contents should be declared as $25 or less if you do not wish to pay customs.
