hi
there is 2 issues here:
1) the volume of your shipment
2) customs
about the volume: in this site we install
cubic feet calculator, so you can calculate your self the amount. I took the exact sheet that all
movers uses and add to it features such as print and you can see you weight of your shipment ( 7 pound per cubic feet is the average) and also can see how much cubic meter you have.
you will get very good idea in terms of size.
in terms of customs:
moving companies will provide you a general information it terms of customs. governments changing their regulations. I strongly suggest you to contact your local embassy and visit official website for updates.
good luck
Dan
