Bonded bunker fuel — VLSFO and MGO — carries no consumption tax at the bonded stage, which is the cost floor that separates it from domestic heavy oil. The recent widening of the green marine-fuel pilot (LNG, methanol) to more hubs is re-pricing the bunkering math for international transshipment tonnage calling at Zhoushan and the outer Shanghai port.

On Oct 20, 2026, SNSUC upgraded its carbon compliance platform DCS+ with a new LNG bunker fuel lifecycle carbon footprinting module — covering 7 stages from extraction to bunkering — validated by DNV.
