Storage conditions by product category
The categories below behave differently enough that a warehouse quote should state which conditions apply to which items. Where a facility cannot meet the condition for a category, the honest answer is that it should not hold that category, and a client is better served by moving the item than by accepting a condition it will pay for twice.
Apparel. Cotton and cotton-rich garments absorb atmospheric moisture, which in a closed carton produces a musty smell that does not wash out reliably and is the most common complaint about long-stored clothing. Requirements are a dry space, storage off the floor, and folded rather than hung, stacked in a way that the top layer is not crushing the layer below. Knitwear is more sensitive than woven fabric and does not recover from compression as well. Printed garments need protection from abrasion at box edges, which is why an inner bag or a shelf rather than a bare stack is the normal arrangement. Black and dark garments have a lower tolerance for any fibre transfer from adjacent materials than white ones.
Print, paper and stationery. Paper responds to humidity in both directions: it gains moisture and waves, or loses it and curls, and either direction makes a printed surface mark a neighbouring sheet on contact. Requirements are flat storage, adequate ventilation, and a rule against stacking weight on top of printed surfaces. Notebooks, diaries and any item with a coated or foil-covered surface are more sensitive still, because the coating can dull, and a presentation box with an adhesive closure can fail in sustained warmth. Posters, large-format prints and anything supplied flat should be stored flat with interleaving so the printed face does not touch.
Electronics and powered accessories. Anything containing a lithium cell needs more than a dry shelf. Requirements include protection from heat and direct sun, avoidance of stacking loads on top of boxed batteries, and a position away from any heat source. A lithium-containing item also carries transport requirements of its own, which is why the storage arrangement and the dispatch arrangement should be held by the same party: stock that cannot legally or safely be shipped cannot be usefully stored either. Power banks and similar items should be held at partial rather than full charge where that is practical, and should not be left indefinitely.
Drinkware, glass and ceramics. The risk here is mechanical rather than environmental, and it comes from stacking. Requirements are stacking limits by item type, with boxed drinkware stacked to the carton strength rather than to the available height, and glass or ceramic ware stored without overstack. Breakage in storage is also a picking risk, so a broken item discovered at pick time is a stock discrepancy and should be recorded as such.
Textiles, bags and soft goods. Totes, towels, blankets and similar items are relatively tolerant of temperature but sensitive to moisture, pests and compression. They should be stored off the floor in a way that allows inspection, and a periodic pest check belongs in the routine rather than being an annual treatment.
