Hi [B]leuname[/B], welcome to CDFreaks!
As [B]cd pirate[/B] and [B]jamescooley1[/B] suggest, there are other scratch resistant media than the TDK ScratchProof media, and I would also prefer some of those over TDK 16x ScratchProof media (TDK 8x ScratchProof media is pretty good though).
SVP in the U.K ship to many European countries:
TDK ScratchProof 16x DVD+R at SVP
TDK ScratchProof 16x DVD-R is listed but out of stock at SVP
WeSellCD ship to a few European countries:
TDK ScratchProof 16x DVD+R at WeSellCD
TDK ScratchProof 16x DVD-R at WeSellCD
I would however suggest other scratch resistant media instead of the TDK 16x media.
The best bargain right now are Maxell Xtreme ProTek in 100/150pc packages from SVP:

The best scratch resistant DVD media might be Verbatim Archival Grade, which is scratch resistant, has a gold+silver reflective layer and an inkjet printable surface:
Verbatim Archival Grade 8x DVD-R at WeSellCD
Verbatim also has another scratch resistant DVD without the gold and without the printable layer:
