Step-by-step formula to calculate desiccant quantity for shipping containers by volume (m³) and relative humidity. Quick lookup tables for 20ft (33 m³) and 40ft (67 m³) containers by cargo type — timber, food, electronics — with worked examples and a safety bias of ×1.2.
Each container cargo type — wood, food, electronics, apparel, machinery, chemicals, agriculture — has different moisture control requirements. This article provides a practical decision matrix to select the right desiccant type (silica gel, clay, CaCl₂) and packaging spec per cargo.
Silica gel and calcium chloride (CaCl₂) use entirely different moisture absorption mechanisms — physical vs chemical. This article clarifies when CaCl₂ (200–250% w/w) is needed for high-RH containers and when silica gel is sufficient and more stable. The right choice leads to significant cost saving
Silica gel and clay desiccants are both widely used in cargo protection, yet differ significantly in material structure, absorption performance, and cost. This guide compares both in detail to help you choose the right type for containers, timber, or garments — with a 30–40% cost gap.
