The proposal is to import a dense grade of ammonium nitrate (known as "NITRAM"') from the UK in quantities of 2,000 tonnes at a frequency of three times per year through the Port of Esperance. The product would be transported in 1 ton bulka bags.

Two ships, each with 2,000 tonnes of NITRAM, have left their ports of loading already: one is delayed in Africa, the other is proceeding to Australia. The ammonium nitrate is needed to fill an Australia-wide shortfall. Esperance is the port preferred by the proponent for imports to service the Kalgoorlie area. Esperance does not have facilities for handling shipping containers (although some ships have container unloading equipment). Thus, it is necessary for the ammonium nitrate to be handled in 'bulka bags' - These bags are made of high strength woven plastic.
