Yup. I make billet stuff for F150's and ship out all of the time. Depends upon the size of what you're shipping, but it's not much more expensive. I've shipped to Germany,Ireland, Italy, Mexico, Brazil, Canada, etc. Never any problem!
Just be sure to go the post office and ask them what is the best way. Lots of times, cuz my stuff is small, I just pop it out normal airmail and it's maybe 50 cents to $1 more. Not too bad, unless there's some serious weight...then I can't help you.
Good luck.
