The sellers, mainly traders and small to medium-sized alumina plants, still have strong shipment intentions as spring approaches. The reason for the active shipment of traders is mainly due to concerns that market prices will continue to fall after the holiday, so they are shipping moderately in advance to hedge. The active shipment of small to medium-sized alumina plants is mainly because their bagged inventory space is limited, the stock in the silos is increasing, and there are growing concerns about working capital, especially since buying ore often requires prepayment. The direct reason for the strong shipment intention of these two main groups is the insufficient signing of long-term external sales contracts with aluminum plants since the beginning of the year.
