I moved to Qatar in November 2017 and just bought my regular luggage of 32 Kg. You don't need to carry lot of stuffs to Qatar as you can buy your stuffs at good prices. All you need to carry is at least three pairs of business suit and personal grooming stuffs. Rest you can go for a fully furnished apartment and you would just require to fill your closet. If not you can buy all household stuffs at half the price in Friday market. So don't stress too much in shipping your items.
