If I were to import a component that was cast in the US, but machined (finished) in Canada, what would be the country of origin? Additional info: say cost of casting in US was £30k and cost of machining in Canada was £20k. Finished goods of this category attract 2% duty when imported from US, but 0% duty when imported from Canada. How do I calculate how much duty will be payable? Finally, would it make a difference if the parts were shipped from the US or from Canada?
