From memory there are not too many sellers in the forum who ship regularly to Germany, but some new requirements were passed into law on the 1st of January and will come into full force on the 1st of March, which will  affect anyone who ships to Germany, even if it's just once a year.

The basic jist of it, is that Germany has introduced some regulations for anyone sending items there in packaging - sellers are required to register with a central packaging agency, pay an annual license fee, and supply information about projected volume of packages, as well as packaging type - the move is to encourage sellers to use recyclable packaging, and by the sounds of it, licensing fees will eventually be based on the sutainability or "eco-friendliness" of the packaging that has been registered.

Currently incoming packages seem to be unhindered by this new regulation, but in a couple of weeks, that may change, with warnings, cease and desist letters, packages being destroyed, and even fines up to 200k Euros become a possibility.
