In my experience they will make you pay the tax. To get around the taxes you need to ship your things with-in 30 days of your arrival (doesn't need be your original arrival) to VN. And, make sure that the sender name is exactly the same as the receiver name. Even if the family name is the same but the first name is different they will tax you. It seems that everything is taxed at different rates so the process can take sometime. One way to avoid paying so much is to put some medicine in the package and claim that it is expensive. Medicine is non-taxable so if you do an itemization you can fudge things a little.

Recently I brought in over 6 cubic meters of personal effects (3 items of furniture, 20 boxes of books, a bicycle, other household stuff). I used an international housemoving company, Crown Relocators, to do the job. While the stuff stayed in quarantine for a few weeks in Hai Phong, no tax was sought. Perhaps this is the secret - you get a reputable company to do the whole thing door-to-door, including customs clearance. That way you avoid all of the problems but you probably have to pay much more for it.
