imdg-7Carrying  Irradiated fuel, Plutonium and high level waste on board ships

Back to the certificates again, this time one that applies to a small number of specialised vessels.

Why is the certificate required?

It is required by The international code for the safe carriage of packaged irradiated fuel, Plutonium and high level waste on board ships (INF code.)

What other document is required by the INF code?

Every ship carrying INF cargo shall carry on board a shipboard emergency plan.

What information is contained on the Certificate?

  • Particulars of ship
    • Name of ship
    • Distinctive number or letters
    • Port of registry
    • Gross tonnage
    • IMO Number
  • INF class of ship
  • Completion date of the survey on which this certificate is based

The certificate must be drawn up in the official language of the issuing country. If the language used is neither English, French  or Spanish, the text should include a translation into one of these languages

What Surveys are required?

The Harmonised System of Survey and Certification (HSSC) does not apply,  however, the UK MCA recommend that the surveys and certification are harmonised with other Convention certificates where practicable.

The Surveys

  • An Initial Survey
  • An Annual Survey, within three months before or after each anniversary date of the Certificate, other than where an intermediate survey is required
  • An Intermediate Survey, within three months before or after the second or third anniversary date of the Certificate;
  • A  Renewal Survey

The INF code


This code is required by SOLAS Chapter VII Carriage of dangerous goods Part D-Special requirements for the carriage of packaged irradiated fuel, plutonium and high-level  radioactive wastes on board ships.

The code applies to All ships,  regardless of date and size carrying  INF. It does not apply to warships and naval auxiliary warships used for non commercial purposes.
