Counterfeit products have not been issued officially by or on the authority of a Government, authorised Hydrographic Office or other relevant Government institution and do not satisfy the carriage requirements of the International Convention on the Safety of Life at Sea (see ​Chapter V, Regulations 2.2 and of the Convention). Furthermore, they have not undergone the rigorous checking procedures which take place for official versions; posing a significant safety risk to vessels, crews and cargo.

Our short counterfeit guide can help you to identify genuine ADMIRALTY products and reduce the risk of counterfeits being used for navigation.​
