Bulk Desiccant for Stored Product

If you warehouse, crate, or hold product for any length of time, humidity is quietly writing off some of it — corrosion on metal parts, mold on textiles and packaging, delamination, spotting, and the returns that follow. It rarely shows up as a line item because it gets recorded as damage, not as a moisture problem.

Sta-Dri supplies bulk montmorillonite clay desiccant for exactly this: keeping moisture away from product that is stored, staged, crated or shipped. We're a US manufacturer, the clay is mined in the American Southwest, and packaging is done in the USA.

• Warehousing and 3PL — palletized goods, long dwell times, unconditioned space.
• Export crating and freight — product sealed in a crate or container across climate zones.
• Equipment and parts distributors — machined metal, bearings, tooling, spares.
• Seasonal inventory — powersports, marine, outdoor goods held through the off-season.
• Archives and collections — documents, textiles, media, instruments.
• Ammunition and firearms distribution — sealed cases and long-term storage.

The common thread is enclosed storage — a crate, case, carton, container, bin or wrapped pallet. Sta-Dri treats the air inside a sealed space. It is not a warehouse dehumidifier and won't condition an open building.

The failure mode that matters for stored product is the desiccant damaging the thing it was supposed to protect.

• Non-corrosive. Sta-Dri contains no calcium chloride. There is no brine to form, so nothing to leak onto goods, packaging or crate interiors.
• Solid fill, not gel or salt. Nothing pools if a pouch is crushed in transit.
• Safe in direct contact with metal, leather, textiles, paper and finished surfaces.
• Non-toxic and non-flammable, with no additives — relevant for shared storage and mixed freight.
• Exceeds U.S. military storage specifications. The specification defines a desiccant unit as absorbing at least 3 grams of water vapour at 20% RH and 6 grams at 40% RH; a unit of Sta-Dri is one ounce (28.35 grams).
• Rechargeable in a conventional oven for up to three cycles — and spent packs need no special disposal. The fill is mined clay with no additives, so spent desiccant is not a hazardous-waste line item.

Specify by enclosed volume: 1 pound per 13.3 cubic feet of sealed space. For crating and container work it's usually easier to work in desiccant units against the air volume and the expected transit or dwell time.

Standard pack sizes are 4, 8, 16, 32 and 64 oz. Tell us the enclosure and the conditions and we'll work the quantity with you.

Tell us what you're storing and roughly how much you need. We'll come back with pricing and a recommended pack size and quantity.

If you are buying against a specification, name it. MIL-D-3464 unit counts, a bag type, a preservation standard — whatever the purchase order says. We will tell you what we can document rather than guess.

Helpful to include: the enclosure (crate, container, carton, pallet wrap, case), approximate internal volume, how long product sits, and whether packs will be recovered and reused.
