    However this "Group C" classifiion applies to bauxite which meets certain parameters for particle size (70% to 90% lumps: mm to 500 mm / 10% to 30% powder) and moisture content (0% to 10%). If the bauxite cargo comprises a finer material, or if it has more moisture, then it should not automatically be considered as a "safe" "Group C" cargo.
