I'm not from Belgium, but I'm guessing German and Belgium customs are not so different. I basically have to pay the sales tax (that you pay in stores) on the sum of the product price and shipping. In Germany that is 19%.
The guys at the customs office here in my hometown are nice. Perhaps you can just call or visit your local office and ask what to expect and how it is handled? Just mention it's the first time you import something on your own and don't want to make any mistakes.
One one my friends ordered some goods from Japan, and had to pay VAT and a custom fee (kind of fine) for file handling.
And everything was done via paper mail, no phone or mail, look's very old fashion.
Haha I have a bad experience with this all. When I, 3 years ago wanted to come into the hobby I ordered this super nice Eurofighter Typhoon with my dad from the USA. Had to pay about $200 extra with shipping and vat etc. The plane was only $300 so I lost a lot of money. Still never flown the plane, because I wanted to maiden it in the US, since I'm moving to the USA. That's how to waste $200.
Hey friend, I just wanted to let you know that Graupner products are marked out of stock because they are currently being loaded in. Above is the photo of the product on the loading dock.
You should be able to order soon.
