No. Labeling storage bins? Seems perfectly normal to me. If you also label your dresser drawers and kitchen cabinets then I think it might be OCD or maybe you are losing your memory (which of course is a serious matter and unrelated to OCD).
I have little boxes in my bathroom closet that label. One full of mini shampoos and soaps, one full of medications, one full of sewing thread and needles, and a few others. Why would I want to bother opening every box every time I need something out of one. I don’t use those boxes much so I don’t remember which one is where. I have 5 plastic small bins of travel items. One with the FL and GA, another international, another TN, AR, MO, aother NY, etc. Why would I want to pull them all down, at a glance I can see what states I have where, and what I don’t. I am one of the least organized people I know and I still do some of that.
