What is ISS Certificate
The ISS Certificate means the International Ship Security Certificate issued for a ship or offshore unit (rig/vessel) in accordance with the International Ship and Port Facility Security (ISPS) Code.

Important clarification
The term “ISS Certificate” in maritime law strictly refers to the International Ship Security Certificate.
Sections such as:
-
“ISS Certified professional”
-
“ISS Certificate of Completion”
-
training programmes, staff certification or corporate screening processes
are not related to the maritime ISS Certificate under the ISPS Code.
They refer to internal or private certification schemes and should not be confused with the International Ship Security Certificate used for ships and rigs.
