I admit right now I have basically no understanding of U.S import/export laws, but I'm comfortable with Canadian ones.

A friend in MN who's trying to ship me an unfinished walnut gunstock for my Savage (value not exceeding $500 w/ship, and he has the invoice for it), and I need to know what I/he need(s) to do the safely and legally get it across the border.

We're trying to ship with UPS, but any carrier that would do this would be nice.

Please leave suggestions...
