4.1 Prior to the entry into force of the Convention,
an Administration may conduct surveys of ships in accordance with
these guidelines, and may then issue a statement of compliance to
that effect.

For the certificate to be issued, it may not be necessary for the
ships to prepare the visual/sampling check plan required by regulation 5.2 of the annex to the Convention
if the Inventory of Hazardous Materials has been developed in accordance

has been verified through the process of issuing the statement of
compliance.
