Kolkata and Haldia Need Desiccants Because Humidity Is Built Into the Route
Tea, leather and jute are especially unforgiving of trapped humidity: aroma loss, mould, staining and odour can appear before the cargo looks visibly wet. Chemicals and engineering goods face caking, liner sweat and corrosion. The river-port environment adds dwell-time moisture before the ocean leg begins.
BENZ uses calcium chloride for container-level moisture, silica gel or molecular sieve for small food/pharma/instrument packs, and C DRY for clean barrier packs or metal-sensitive cargo.
