I was shipping a laptop battery purchased on a U.S. site to Canada. Reship.com's competitor told me "no". Reship.com emailed me that they would do it and I would pay by weight like with any shipment. The reality was much more difficult. Many delays within Reship.com and then with the shipper, UPS. When Justin from Reship.com got involved, it changed. He figured out all of the paperwork and insisted UPS get me the shipment (at no additional charge). It took some months but I did get my battery due to his determination.
Warning to others: think long and hard before you buy a laptop battery in the U.S. and try to ship it abroad. It has become much more difficult than it used to be.
