In bringing back some large items from Canada to US through customs, my experience was that if the item going
through customs was originally made in USA, there was no duty to pay at the border. I don't know where all
Excello mills were made but I do know at least some of them are made in Canada. My experience tells me that
there may be duty to pay. Things may have changed too so it may be different now. If it's just a quill spring, it
might not be significant. The seller may have experienced difficulties shipping to USA. There is a way but it might
be a little convoluted.
