I'm ordering a batch of 100 cassette tapes from Canada, so it will be fairly bulky/heavy.

The company i'm buying them from has said that they won't charge me any taxes from their end, but that there may possibly be some extra taxes (excise/customs?) added on top when the goods enter the UK.

Is there a way of finding out if I will have to pay these taxes, and if so, how much they will be?

Obviously, I want to make sure I pay my fair share.

Thanks!
