Label the location
Shelf and bin labels usually need less maintenance than tagging every object.
Use plain words
Everyone should understand the category name.
Add dates where turnover matters
Seasonal and archival storage can benefit from year or review-date information.
Keep labels editable
Categories change, so replaceable labels are practical.
Practical boundary. Measure first, respect product load limits, and do not improvise wall, ceiling or overhead installations when the structure or appropriate hardware is uncertain.
