I run a small on-line retail store in the US and have a TON of requests to ship to Canada. How do I go about calculating the taxes and tariffs prior to shipping. When I called and talked to Fed-Ex they said they can't estimate them prior to shipping I would have to wait until the package got to Canada and then they would bill me. It is really hard for me to determine how much to charge on shipping when I can't estimate. I use a combination of USPS, Fed-Ex and UPS.
I also was trying to figure out the codes I am supposed to use for shipping orders into the country which are asked for on the USPS customs forms and couldn't find them.
Thanks for any guidance.
