This winter I will be shipping my seats to the US to have them fixed up and recovered. My question is how do I register my seats with customs so I only have to pay taxes on the repairs and not for the full value the seats will be insured for on the way back. On the way down I will insure them for, lets say 1000 but when the come back they will be insured for 2000, I only want o pay on the extra 1000, any thoughts, has anyone done this before.

Thanks
