Just received a Fedex invoice for £61.16 for a spindle and vfd Chinese import, which didnt make my day :(

I've bought loads of stuff from China inc hiwin rails and vfd's etc and I cant remember paying that amount of duty or often any duty at all on these purchases.

Have I just been lucky or are the spindle and vfd packages in particular always subject to 20% duty?

ps
Just on another note the postman due to his diligance and professionalism has managed to get this invoice through my letterbox even though the name, the number, the street are all wrong. Only the postcode is correct. I'm wondering if its even valid as such?
