            • Appendix to Low Sulfur Fuel Oil Futures Contract of the Shanghai International Energy Exchange


            I. Delivery Unit
            The delivery unit of low sulfur fuel oil futures contract is 10 metric tons. The delivery quantity shall be integral multiple(s) of the delivery unit.
            II. Quality Standards
            Low sulfur marine fuel oil to be delivered shall meet the quality standards for low sulfur marine fuel oil set by the Shanghai International Energy Exchange (the “Exchange”). “Low sulfur marine fuel oil” refers to homogeneous hydrocarbon mixtures extracted from petroleum, with certain amount of additives permitted for performance and characteristics gains. Low sulfur marine fuel oil shall not contain any inorganic acid and used lubricating oil, nor any substance that may cause abnormal operations of ships, nor any artificially added additive or chemical waste that may endanger ship safety, adversely affect machine’s performance, or be harmful or increase air pollutions.
            Specific rates of premium and discount will be separately prescribed and announced by the Exchange.
