Sorry I have to say this, but from my experiences this is not completely true. 
At least for me they just offer two shipping methods: With DHL they just give the package to DHL. With this method you have to pay the duty when the package arrives. In some countries (like Germany) you may have luck that they āoverlookā the package, but you canāt rely on that. The second shipping method is via UPS. You have to pay a lot more, but in this case UPS handles the duty for you.
In both cases Fangamer just fills out the necessary papers for the transport company but they donāt seem to know how the packages are handled by DHL or UPS. And they couldnāt answer my corresponding questions regarding the (handle of) the duty properly (they just stated that I have the choice between those two shipping methods and that I have to chose the correct one).
The shippments via DHL had the standard invoice as I knew it from a typical delivery. In my case Fangamer set all prices to 0, so the costs for the shippements were 0 Dollars and the products costs 0 Dollars. This is horrible because now I have to prove to the (German) duty what Iāve paid for the package. I have to print out the (e-mail) confirmation from Fangamer. Otherwise the (German) duty department is allowed to guess the value of the package contents. So if I donāt have luck (and the e-mail confirmation), I have to pay a higher duty as necessary. The latter problem is the case with the Kickstarter stuff because in the only confirmation e-mail I got, only the content of the package(s) is listed. So after having already āfunā with the duty and Fangamer packages, Iām really looking forward to the discussion with my duty officer(s) about my Kickstarter package(s). 
So yes, Fangamer knows how to send parcels to other countries, but they could improve this.
