To be EPR (Extended Producer Responsibility) compliant in Germany, you need to register of the relevant EPR registration authority, to obtain your EPR registration number(s). You need this EPR registration number(s) as proof of compliance. Additionally you need to licence your products subject to EPR requirements to a Producer Responsibility Organisation (PRO) responsible in Germany. Therefore you must declare your sales (of products covered by the different EPR categories) to the respective Producer Responsibility Organisation (PRO) for the applicable reporting period and pay eco-contributions to your PRO. The PRO will then take responsibility for the collection and recycling of your product.
