The country implemented the ban on all mineral ore exports, including unprocessed nickel ore in January 2014, but excluded partially processed copper, iron, zinc, lead and manganese concentrates Type 1 minerals until 2017. Indonesia's ban on exports of nickel ore has pushed the Philippines to be the top nickel ore supplier to China.

Focus: Cargoes subject to liquefaction SAFETY4SEA. IMSBC Code Group A Nickel Ore Iron Ore Fines Bauxite Cargo liquefaction may result in cargo shift and loss of stability this has been the cause of a number of serious casualties during the last years and now liquefaction is being considered as a major hazard for bulk carriers.

To prevent sliding and shifting of ore concentrates in storage a biodegradable materials are added to the ore. The polymer materials absorb water from the ore particles pores and the moisture content goes down. In con sequence polymer materials may prevent drainage of the water from the ore particles pore.

The largest exporters of nickel ore have traditionally been Indonesia and the Philippines, but since the Indonesian ban on export of several types of unprocessed ores in January 2014, the Philippines has by far been the largest exporting country. The vast majority of nickel ore is shipped to China, where it is used for making stainless steel.
