In order to take advantage of the provision, transport fuel suppliers have to demonstrate that at least 70% of the biofuels they blend each year come from “registered producers,” both from Poland and other countries, said the source at Poland’s Agency of Agricultural Market, or ARR, the agency’s Polish-language acronym. The ARR is responsible for registering producers. “In order to apply for registration, producers have to be set up in accordance with the Polish law or have a Polish branch,” the source added.

...While it is not clear what percentage of biofuels Poland currently requires in its transportation fuels, draft legislation considered last year envisioned a 6.65% blend in 2012. The Ministry of Economy, responsible for the general biofuels policy, was not available for clarification.
