AMSA New Exemption EX5739 Relating to Corrosive Properties of Solid Bulk Cargoes

A refined Materials Hazardous only in Bulk (MHB) corrosivity (CR) test has been developed which prescribes testing of representative samples of the cargo at conditions representing their as-shipped properties. The International Maritime Organization (IMO) formally published this interim guidance in January 2019 MSC.1/Circ.1600 Interim Guidance for Conducting the Refined MHB (CR) Corrosivity Test. AMSA have recently issued exemption EX5739 which allows shippers to use this guidance in the circular until 31 December 2022 when it is agreed and finalised in the 06-21 amendments to the IMSBC Code, considering the mandatory entry into force would be 1 January 2023.
 
AMSA have previously issued two exemptions also relating to corrosivity:

• Exemption 5717 to section 334 of the Navigation Act 2012 and
• Exemption 5718 to section 334 of the Navigation Act 2012 

Both of which will expire on 30 June 2019.
