Institute Cargo Clauses “C” give basic cover against major casualties as well as general average sacrifice and jettison. Theft is not covered.
The “B” Clauses extend the “C” cover to include earthquake, volcanic eruption, lightning, washing overboard, entry of sea into the vessel, total loss of packages lost overboard during loading or unloading. Theft is still not covered. The “A” Clauses give cover “Against All Risks of loss of or damage to the subject matter insured”, making the policy almost “fully comprehensive”. However, ordinary leakage, ordinary loss in weight or volume, ordinary wear and tear, inherent vice, and delay are excluded. The Institute Strikes Clauses are also added to the policy.
