the costs can be very different from around the world, ring around a few freight places and most will be able to quote you . but on average it will be from 800 - 1500 for freight place charges and if air or sea ectect
always remember you will have to add GST on them
when they arrive. I normally bring in containers and have only a few times brought in 1s and 2s
where abouts in USA ? as I am bringing a few parts in might be able to add it for you
PM me as I will be checking here while away.
