CARGO
Flow Moisture Point (FMP) Is the maximum water content, expressed as a percentage, at which a sample of cargo will begin to flow. Cargoes with moisture content close to, equal to or in excess of the FMP may liquefy or dynamically separate. The FMP is determined using the flow table test (method 1.1) or penetration test (method 1.2).

Transportable Moisture Limit (TML) of the cargo being loaded, together with its Flow Moisture Point (FMP). The FMP of a bulk cargo can only be officially determined by a competent independent laboratory. The TML is 90% of the FMP, and cargoes with an average moisture content level higher than 90% FMP should never be loaded.

Iron ore and iron ore fines are two separate cargoes. Iron ore largely comprises lumpy material resembling small rocks or stones of 10-25 mm in diameter. It is defined as a category 'C' cargo under the IMSBC Code, meaning it is not liable to liquefy. Iron ore fines are largely made up of powdery material below
