If you have obligations as a WEEE producer you may also have obligations as a packaging producer in the EU countries where you sell. The Packaging Directive (94/62/EC) is older than the WEEE Directive and it does not explicitly mention obligations for distance sellers. However, several EU countries do oblige foreign entities selling directly to end users to comply with their national packaging laws. All EU countries oblige legal entities established in the same country where they sell products into to comply with packaging regulations.
