1 Categories of liquids
The following categories subdivide the full scope of substances covered by Annex I of
MARPOL 73/78 and set in groups specific products for general identification purposed to define
the technical and environmental parameters required for the MSDS.
- crude oils;
- fuel and residual oils, including ship.s bunkers (ISO 8217, table 2);
- unfinished distillates, hydraulic oils and lubricating oils;
- gas oils, including ship.s bunkers (ISO 8217, table 1);
- kerosenes;
- napthas and condensates;
- gasoline blending stocks;
- gasolines and spirits; and
- asphalt solutions.
