For nickel ore, the Ramadan period in Indonesia is drawing to a close, and RKAB quotas are expected to be released. However, against a backdrop of tightened supply, the volume of quotas released is likely to remain constrained. Nickel ore continues to provide price support. At present, mainstream premiums in the Indonesian market remain around US $35-$40/wmt, while ore used for HPAL processing has seen prices increase by US $2-$3/wmt, reflecting tight nickel ore supply. Meanwhile, Indonesia's rainy season is approaching, and market participants are advised to monitor whether it will impact nickel ore shipments.The decline in nickel prices last week put downward pressure on nickel sulfate prices and weakened cost support, leading some market participants to lower their previously firm price quotes. On March 20, nickel sulfate prices fell by Yuan 750/tonne to Yuan 31,250/tonne.
