Copra: IMSBC Code Schedule and Carriage
The COPRA schedule: a Group B cargo that depletes oxygen and generates heat biologically, and the sealed-hold and cooling response the Code prescribes.
Copra is dried coconut flesh, carried in bulk as a feedstock for coconut oil extraction, and it is a Group B cargo under the IMSBC Code. It generates carbon dioxide and heat through biological activity, depletes oxygen through oxidation of its oil content, and can reach temperatures sufficient to ignite.
The full article will cover the schedule field by field, including the requirement that cargo spaces be kept closed with cool water applied to the external surfaces of the cargo space if temperatures rise excessively, which is a sealed-hold response written into the Code rather than left to loss-prevention guidance.
It will also cover the moisture and free fatty acid thresholds that govern acceptance, and the enclosed-space entry hazard the cargo shares with fishmeal, seed cake and wood pellets.
