What are the differences between Institute Cargo Clauses A and Institute Cargo Clauses C?

There are 3 types of marine cargo insurance policies available for international transactions.

These marine cargo insurance policy types are known as Institute Cargo Clauses (A), Institute Cargo Clauses (B) and Institute Cargo Clauses (C).

Each marine cargo policy type covers different amount of risks, whereas Institute Cargo Clauses (C) has the minimum coverage and Institute Cargo Clauses (A), also known as all risks, has the maximum coverage.
