When particle size changes the shipping classification
Particle size can materially change how a solid bulk cargo behaves in transport. For phosphate rock fines, that difference was significant enough to support a new Group A IMSBC schedule for liquefaction risk. This case study looks at why the classification changed, what that means operationally, and how the technical case was developed.
The bulk shipper's declaration: a short form, a detailed process
Establishing what goes the bulk shipper’s declaration can take a laboratory, a battery of tests, and judgement across multiple separate regulatory codes. The declaration (in Australia, AMSA form 268) sits under the SOLAS Convention, and on a single page it draws together the IMSBC Code classification, the chemical hazard from the IMDG Code, and the classification relating to MARPOL Annex V. Underpinning these regulations is the UN GHS. The form is simple; the classification behind it is often not. Some cargoes are straightforward; others require an extensive testing and assessment process.
AMSA Exemptions relating to corrosive properties of solid bulk cargoes
The Australian Maritime Safety Authority (AMSA) has recently issued two exemptions that change how the corrosive properties of certain solid bulk cargoes are assessed. These exemptions provide more flexibility and targeted testing methods for shippers.
