Beijing-based commodity market information provider JLC Network Technology Co. recently shared its JLC China Bunker monthly report for June 2025 with Manifold Times through an exclusive arrangement:
Bunker Fuel Demand
China’s bonded bunker fuel sales inch lower in June
China’s bonded bunker fuel sales inched lower in June, due to the negative impact from geopolitical tensions and seasonally tepid shipping demand.
The country sold about 1.74 million mt of bonded bunker fuel in June, with the daily sales at 57,910 mt, a dip of 0.26% month on month, JLC’s data shows.
Bonded bunker fuel sales by Chimbusco, Sinopec (Zhoushan), SinoBunker and China Changjiang Bunker (Sinopec) respectively settled at 460,000 mt, 560,000 mt, 45,000 mt and 25,000 mt in the month, while those by suppliers with regional bunkering licenses stood at 647,300 mt.
The efficiency of global trade declined amid trade war, leading to a slip in the world’s bunkering demand.
China’s LSFO output rallies in June
China’s LSFO output rallied in June amid unit restarts, but the rally was limited to some degree by some refineries’ maintenance and bad production margins.
Chinese refiners produced about 1.02 million mt of LSFO in the month, with the daily output rising by 10.58% month on month to 34,067 mt, JLC’s data shows.
Specifically, Sinopec maintained basically stable LSFO production in June. The company’s Shengli Oilfield and Jinling Petrochemical slashed their production after launching maintenance in the middle of the month, while Shanghai Gaoqiao Petrochemical, Hunan Petrochemical and Tianjin Petrochemical wrapped up turnarounds and boosted their output.
PetroChina recorded a modest rise in its production in June as Jinxi Petrochemical restarted its units. However, Jinzhou Petrochemical and Liaohe Petrochemical slightly cut their production. The output of other refineries did not change much in the month.
CNOOC saw a significant boost in its output in the month, as Huizhou Refinery resumed production while Zhoushan Petrochemical and Taizhou Petrochemical ramped up production.
ZPC and Sinochem did not produce any LSFO in June, but the latter exported 10,000 mt of MGO.
On a year-on-year comparison, however, China’s LSFO output fell by 22.75% in June.


Domestic-trade bunker fuel demand weakens in June
Domestic-trade bunker fuel demand further weakened in June, with most shipowners still holding a wait-and-see attitude.
Domestic-trade heavy bunker fuel demand slipped to 340,000 mt in the month, down 20,000 mt or 5.56% from the previous month, JLC’s data shows. Most purchases were still based on rigid demand, though market sentiment became slightly bullish.
Meanwhile, domestic-trade light bunker fuel demand declined to 140,000 mt, down 10,000 mt or 6.67% month on month. Diesel demand remained lackluster amid the fishing moratorium.
Bunker Fuel Supply
China’s bonded bunker fuel imports rebound in May
China’s bonded bunker fuel imports rebounded in May, as domestic refiners increased purchases of imported LSFO when domestic supply tightened.
Chinese bunker suppliers imported 610,500 mt of bonded bunker fuel in the month, a boost of 16.17% month on month and 97.06% year on year, JLC’s calculation shows, based on data from the GACC.
Domestic LSFO output extended declines amid more unit maintenance, forcing bonded distributors to place more orders for imported LSFO. Meanwhile, HSFO imports increased amid growing demand, while MGO arrivals dropped amid larger domestic production and tepid demand.
Russia became the largest bonded bunker fuel supplier to China in May, up from the fourth place in April. The country exported 377,700 mt of bonded bunker fuel to China in the month, accounting for 61.88% of the latter’s total imports. At the same time, Singapore came second with 144,500 mt, accounting for 23.67%, while South Korea ranked third with 50,300 mt, accounting for 8.23%. In addition, Malaysia ranked fourth with 38,000 mt, occupying 6.22%.
China’s bonded bunker fuel imports totaled 2.66 million mt in January-May, surging by 64.54% year on year, the calculation shows.

Domestic-trade bunker fuel supply continues to tighten in June
Domestic-trade bunker fuel supply continued to tighten in June, as the availability of blendstock declined and most blending in northeast and east China was still at a halt.
Blenders supplied about 360,000 mt of domestic-trade heavy bunker fuel in the month, down by 10,000 mt or 2.70% month on month, JLC’s data shows.
Domestic supply of low-sulfur residual oil tightened as China Offshore Bitumen (Binzhou) came under maintenance, while that of shale oil also declined. Meanwhile, most blenders in northeast and eastern China were yet to resume their blending, as the impact of tax inspections persisted.
Domestic-trade light bunker fuel supply dropped to 150,000 mt in June, down by 10,000 mt or 6.25% month on month, the data shows. Diesel supply tightened as some refineries lowered their operating rates amid unit maintenance.
