Description
Cocoa beans are shipped in jute or similar bags from tropical producers to processors, a high-value and delicate cargo. The effective stowage factor around 1.45 m3/t reflects the bags and the broken stowage. Its care is dominated by moisture, condensation and taint, with mould and infestation the principal threats to quality.
Stowage & loading
Bags are stowed on dunnage with ventilation channels, in scrupulously clean, dry, odour-free holds, since cocoa both taints readily and absorbs odours. A stable stow is built and torn bags set aside. Wet-weather loading is managed closely, as wetting quickly damages the beans.
Hazards & handling
Cocoa is hygroscopic and very prone to sweat and condensation damage, with mould and caking following any moisture, and it is highly taint-sensitive in both directions. Insect infestation is a recognised problem, so fumigation is common. Bag breakage and broken stowage are the main handling concerns.
Carriage & discharge
Hold ventilation is managed carefully on a dew-point basis to control ship and cargo sweat, the key to delivering the beans sound, and the stow is monitored for moisture and heating. Discharge is by sling or net, with damaged bags segregated and holds cleaned of residue.
Key hazards
- Sweat and condensation damage, mould and caking from moisture
- High taint sensitivity, both absorbing and imparting odours
- Insect infestation and bag breakage
Loading precautions
- Present scrupulously clean, dry, odour-free holds and dunnage with ventilation channels
- Build a stable stow, set aside torn bags and manage wet-weather handling
- Confirm fumigation arrangements against infestation
Stowage factors are indicative and vary with grade, origin, moisture and packing. Always verify against the shipper's cargo declaration and the applicable IMSBC Code schedule before fixing or loading. This is general information, not professional or safety advice.
