[Elecraft] Duty on warranty repairs

[Mike Weir]

Good afternoon, has any Canadian Elecrafters sent a rig to Elecraft for warranty repairs and if so when the radio was return were you charged any duty or HST taxes as it crossed over the boarder? I may be sending a rig down and was just wondering what cross boarder experience was of those who have sent a rig to Elecraft for warranty repairs? 
Thanks in advance
