Exemptions and determinations for cargoes
We have issued the following exemptions and determinations.
Competent authority exemption from the notice requirements in Marine Order 41 (Carriage of dangerous goods) 2017, for an excepted package of radioactive material of class 7
- Exemption number 5671 – in force until 1 August 2020
- Exemption number 6108 – in force from 1 August 2020
exempts a shipper from the manner of giving notice for the shipment of an excepted package of radioactive material of class 7. It includes conditions that provide for alternatives that the notice must include.
Competent authority approval of a modified test, and modified schedule, for coal
AMSA previously issued certificate of approval no.5459, which allowed shippers of coal to use an additional test, the Modified Proctor/Fagerberg method for coal, for evaluation of liquefaction properties of coal. AP5459 was valid until 1 January 2020, however it no longer needs to be used, as the modified test and modified schedule for coal are both included in the 2018 edition of the IMSBC Code, which has been mandatory since 1 January 2019.
Exemption for testing of the material hazardous in bulk—corrosive properties of solid bulk cargoes
We have been working with industry on issues identified with the repeatability and reliability of the modified C.1 test prescribed by section 22.214.171.124.3 of the International Maritime Solid Bulk Cargoes Code (IMSBC code).
We previously issued two exemptions in respect of this issue:
- Exemption 5450 to section 334 of the Navigation Act 2012 - to allow shippers of iron ore, iron ore fines, bauxite and coal to use an alternative method for evaluation of the MHB corrosive properties of iron ore and iron ore fines.
- Exemption 5451 to section 334 of the Navigation Act 2012 to allow shippers of mineral concentrates and metal sulphide concentrates to use a modified C.1 test better suited to the properties of these materials.
Whilst the issues have been progressed at meetings of the sub-committee for the Carriage of Cargoes and Containers (CCC) at IMO, amendments to be included in the 06-21 amendments to the IMSBC Code were finalised and agreed during CCC 5 in September 2018. These were sent to the Maritime Safety Committee in December 2018 for that committee to issue an MSC circular. Until that circular could be formally published AMSA issued two exemptions valid until the end of June 2019, to replace those previously issued:
- Exemption 5717 to section 334 of the Navigation Act 2012 to allow shippers of mineral concentrates and metal sulphide concentrates to use a modified C.1 test better suited to the properties of these materials.
- Exemption 5718 to section 334 of the Navigation Act 2012 to allow shippers of iron ore, iron ore fines, bauxite and coal to use an alternative method for evaluation of the MHB corrosive properties of iron ore and iron ore fines.
MSC.1/Circ.1600 Interim Guidance for Conducting the Refined MHB (CR) Corrosivity Test, dated 10 January 2019, was formally published by the IMO in January 2019. AMSA has issued an exemption valid until 31 December 2022 to allow shippers to use the guidance in the circular until it is agreed and finalised in the 06-21 amendments to the IMSBC Code.
- Exemption 5739 to section 334 of the Navigation Act 2012 to allow shippers of solid bulk cargoes to use the guidance in MSC.1/Circ.1600.
EX 5739 can be used by a shipper for any solid bulk cargo, hence it replaces all previously issued exemptions relating to corrosivity of solid bulk cargoes—EX 5450, EX 5451, EX 5717 and EX 5718—regardless of the date of validity indicated on those certificates.
Approval for MHB categorisation related to self-heating properties of coal
We have been working with industry with regard to issues identified with the repeatability and reliability of the N.4 test prescribed by section 126.96.36.199.3 of the IMSBC code to determine self-heating properties of coal. It was found that actual behaviour of most coal cargoes during transport, or when stored in stockpiles, did not reflect the outcome of the test. Research found significant issues of repeatability with positive and negative results for the same cargo in different tests.
We have previously issued Certificate of approval no. 5460 determination of categorisation of coal as materials hazardous only in bulk approving the categorisation of coal, meeting certain criteria, to be MHB on the condition that extra precautions are taken. As that certificate expires on 31 December 2019, we have issued AP5620 Approval of the categorisation of coal as materials hazardous only in bulk (MHB), valid from 1 January 2020.
Determination for the appropriate test method to categorise bauxite as a group A or group C cargo
Australia, Brazil and Malaysia have been working with industry on the properties of bauxite after the loss of the MV Bulk Jupiter in January 2015. This work was presented to the fourth session of the CCC4 at the IMO.
A new test procedure, a new group A schedule, and a revised group C schedule were agreed at the fourth session of the CCC with a view to incorporation in the 05/2019 amendments to the IMSBC code subject to agreement by the Maritime Safety Committee (MSC). Noting the importance of the need to have an effective mechanism to determine if bauxite may have group A properties the fourth session of the CCC revised CCC.1/Circular 2. The revised CCC.1/Circular 2 revision 1—carriage of bauxite which may liquefy was published on 20 September 2017. This publication provides the details of the new test, new group A schedule, and the revised group C schedule request that administrations take these into account as suitable for the classification and carriage of bauxite.
We have determined, by Certificate of approval no. 5456 determination of the appropriate test method for the categorisation of bauxite that the test and schedules should be applied to bauxite when shipped from Australia in solid form in bulk as detailed in that approval.
