Most of chicago’s issue with “ seeds “ come from the increased complaints from the public receiving “ mysterious “ seeds from foreign countries. Illinois homes and other areas have been flooded with randomly sent seeds of unknown species…fearing a possible invasive species. Department of Agricultural has become more focused on the problem hence a tighter control.
China is one of the culprits ( no shock ) in sending “seeds “ as part of a “ positive review / feedback “ scheme when items are delivered or transaction complete. Even if you didn’t order shit. Delivery to a random address is good enough to mark as “ complete “. So it seems because if the heavy complaint load about random seed packs and their unusual appearance ( some are color coated ) they instruct them to bring into authorities instead of trash.
They worry those packs will grow out in landfill areas if tossed in trash. So they want the public to tape up and drop off to official sources.
Black Hole is right.
