The code for bulk liquefied gas carriers
The International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk, or IGC Code, has been mandatory under SOLAS chapter VII since 1 July 1986. It addresses ship construction and equipment for the cargoes within its scope.
Start by identifying the cargo, the vessel and the applicable code. Bulk gas carriage on a gas carrier requires a different assessment from packaged dangerous goods under the IMDG Code or a road movement under ADR.
What MSC.370(93) introduced
Resolution MSC.370(93) was adopted on 22 May 2014. Its amendments entered into force on 1 January 2016. The revised code generally applies to ships constructed on or after 1 July 2016, using the code’s construction definition and application provisions.
Earlier ships have their own applicable requirements, and some amendments expressly address existing vessels. Establish the construction date and amendment scope before treating the revised text as a checklist for every ship.
Read the revision together with later amendments
For the framework checked on 12 October 2026, consult the IMO supplements as well as the original resolution. The January 2026 supplement records MSC.523(106) amendments to construction materials and quality control, in force from 1 January 2026.
The July 2026 supplement records MSC.566(109), amending the provisions on cargo used as fuel, in force from 1 July 2026. These references identify changes to review; they do not establish approval of a particular installation or operation.
Check the ship’s certification and the actual cargo
IGC compliance is evidenced through the ship’s International Certificate of Fitness for the Carriage of Liquefied Gases in Bulk. Review its permitted products, conditions, attachments and survey status with the responsible ship operator and flag administration.
A CLP hazard classification, SDS or ADR UN number alone does not establish that a product may be carried on that ship. Match the cargo information and proposed voyage to the relevant maritime requirements and ship-specific evidence. Keep road and other transport legs separately assessed.
Prepare documents before confirming the arrangement
A useful review file identifies the ship, flag, construction date, applicable code edition and amendments, certificate, product identity and proposed ports. Ask the responsible maritime specialists to resolve uncertainties about cargo acceptance and certification before the arrangement is confirmed.
DGSA advisory services can help coordinate the dangerous goods transport documentation interface. Contact DGSA with the cargo, transport modes and available documents so the review reflects the actual shipment.
