Tonnage certificates in Connection with flagging in or re-flagging


In order for a vessel to be registered/re-registered under the German flag, an application (Word- or PDF-file, only in German) has to be submitted for the issue of a new tonnage measurement certificate, enclosing a copy of the existing International Tonnage Certificate (1969).

Existing tonnage certificates for the SUEZ and PANAMA Canals generally continue to be valid after a flag change provided that there have been no conversions or changed use of compartments or spaces.

Such tonnage certificates can be issued by the BSH for all flags after re-measurement.
