Beijing-based commodity market information provider JLC Network Technology Co. recently shared its JLC China Bunker monthly report for September 2025 with Manifold Times through an exclusive arrangement:
Bunker Fuel Demand
China’s bonded bunker fuel sales decline in September
China’s bonded bunker fuel sales declined in September, due to multiple factors.
The country sold roughly 1.67 million mt of bonded bunker fuel in the month, with the daily sales at 55,583 mt, down by 2.56% from August, JLC’s data shows.
Port operations in East and South China were affected by a new round of typhoons, and downstream demand for cargo transportation was also depressed. Meanwhile, the bunkering efficiency of some domestic ports decreased amid the US’s sanctions.
The sales by Chimbusco, Sinopec (Zhoushan), SinoBunker and China Changjiang Bunker (Sinopec) respectively settled at 450,000 mt, 530,000 mt, 44,000 mt and 18,000 mt in the month, while those by suppliers with regional bunkering licenses settled at 625,500 mt.
China’s LSFO output slips in September
China’s LSFO output slipped in September, as refiners’ production margins were relatively bad and CNOOC was short of export quotas.
Chinese refiners produced 1.05 million mt of LSFO in the month, with the daily output at 34,933 mt, a cut of 1.55% month on month, JLC’s data shows.
Specifically, Sinopec’s LSFO output was stable in the month. The company’s Shengli Oilfield resumed production after maintenance, while most of the other refineries reduced production after previous boosts.
PetroChina recorded a fall in its output in September, as its Fushun Petrochemical was under maintenance through September and Gaofu Refinery suspended LSFO production. The output of other refineries did not change much in the month.
CNOOC lowered its LSFO production when it was running short of LSFO export quotas. The company’s Zhongjie Petrochemical and Huizhou Petrochemical decelerated their production, while Taizhou Petrochemical slightly boosted its output. The output of Zhoushan Petrochemical was stable month on month.
ZPC and Sinochem did not produce any LSFO in September, but the latter exported about 15,000 mt of MGO.
On a year-on-year comparison, however, China’s LSFO output increased by 5.54% in September.
China has released this year’s third batch of LSFO export quotas, with 605,000 mt, all for Sinopec, according to industry sources.

Domestic-trade bunker fuel demand continues to grow in September
Domestic-trade bunker fuel demand continued to grow in September, because of pre-holiday restocking.
Domestic-trade heavy bunker fuel demand settled at 380,000 mt in the month, growing by 20,000 mt or 5.56% month on month, JLC’s data shows. At the same time, domestic-trade light bunker fuel demand stood at 160,000 mt, rising by 5,000 mt or 3.23% from the prior month.
Shipowners increased purchases of domestic-trade bunker fuel to replenish their inventories before the public holidays for the National Day and the Mid-Autumn Festival. Meanwhile, demand for MGO and bunker fuel was relatively fair after the end of the fishing moratorium in all Chinese waters.
Bunker Fuel Supply
China’s bonded bunker fuel imports tumble in August
China’s bonded bunker fuel imports tumbled in August, with HSFO arrivals decreasing amid relatively high inventories.
Chinese bunker suppliers imported 489,600 mt of bonded bunker fuel in the month, a plunge of 23.88% from the prior month, despite a surge of 38.77% year on year, JLC’s calculations show, based on the GACC data.
Bonded distributors reduced their purchases of imported HSFO as their inventories were relatively high after previous boosts in the imports. However, bonded LSFO arrivals increased, while those of marine gas oil were still basically stable.
As the largest bonded bunker fuel supplier in August, Singapore exported 145,100 mt to China, accounting for 29.63% of the latter’s total imports. South Korea climbed to the second place with 126,700 mt, accounting for 25.88%, while Malaysia slipped to the third place with 110,100 mt, making up 22.48%. Indonesia ranked fourth with 107,700 mt, occupying 22.01%.
China’s bonded bunker fuel imports totaled about 4.34 million mt in January-August 2025, soaring by 55.50% from the same period of time in 2024, the calculations also show.

Domestic-trade heavy bunker fuel supply grows in September
Domestic-trade heavy bunker fuel supply grew further in September, supported by increasing availability of low-sulfur residual oil and higher buying interest.
Chinese blenders supplied about 400,000 mt of domestic-trade heavy bunker fuel in the month, a boost of 20,000 mt or 5.26% from the previous month, JLC’s data shows.
These blenders ramped up their bunker fuel production when upstream supply of low-sulfur residual oil increased. Meanwhile, downstream buying interest grew amid the approach of the public holidays for the National Day and the Mid-Autumn Festival, which also prompted blenders to increase their bunker fuel supply.
Domestic-trade MGO supply settled at 180,000 mt in September, unchanged from the prior month, the data shows.
