Bunker fuel testing and marine surveying business Maritec Pte Ltd (CTI-Maritec) on Wednesday (4 September) released a whitepaper on the main challenges and optimal management of Very Low Sulphur Fuel Oil (VLSFO). 

CTI-Maritec said with the prevalent operational issues associated with VLSFO, understanding the causes and risks are crucial for ship operators and crew to avoid costly operational disruptions and permanent machinery damage.

“Due to the widely varied compositions of VLSFOs sold in the bunker fuel oil market, the physical and chemical properties and qualities vary greatly, thus exhibiting significantly different chemical behaviours, which can only be accurately determined through focused monitoring/testing,” according to the paper’s extract.

“This variability can affect engine performance.”

The firm shared key insights with in-house data evidence on the issues faced along with recommendations to shed light on the optimal testing and management of VLSFO.

“Furthermore, indications of the pitfalls of neglecting to closely monitor VLSFO are also indicated to provide a holistic understanding of the issues at hand,” it said. 

Note: The full whitepaper by CTI-Maritec can be downloaded here.

Bonded bunker fuel sales in Zhoushan (June 2025)

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.

RESIZED ENGINE East of Suez

The following article regarding regional bunker fuel availability outlook for the East of Suez region has been provided by online marine fuels procurement platform ENGINE for publication on Singapore bunkering publication Manifold Times:

  • VLSFO and HSFO lead times vary widely in Singapore
  • Several Chinese ports suspended due to Typhoon Danas
  • Availability good in Sri Lankan ports

Singapore and Malaysia

VLSFO lead times in Singapore remain highly variable. Some suppliers are quoting as few as six days, while others recommend booking up to two weeks in advance due to long-term nominations—typically contract-based stems that take priority over spot demand. Tight loading schedules at some terminals have further contributed to the delays.

Lead times for LSMGO in Singapore have increased, with most suppliers now advising 6–9 days, up from 2–8 days last week. HSFO lead times also vary widely, ranging from 3–12 days, compared to 9–14 days last week.

In Malaysia’s Port Klang, VLSFO and LSMGO remain readily available, with prompt delivery possible for smaller parcels. However, HSFO supply continues to be tight.

East Asia

VLSFO supply in Zhoushan remains steady amid muted demand, with lead times slightly improving to 4–6 days from 5–7 days last week. Most suppliers are well-stocked, but delays in replenishment cargoes have led some to raise prices in anticipation of tighter availability, a trader noted. This has added further upward pressure on the grade’s price.

For other grades, HSFO lead times have extended to 5–7 days, up from 4–6 days last week, while LSMGO lead times have risen more sharply to 4–6 days from the previous 2–4 days.

However, bunker operations at Zhoushan’s outer and inner anchorages have been suspended since Sunday due to adverse weather caused by Typhoon Danas, according to a source.

The typhoon made landfall in Taiwan’s Chiayi County on Sunday and has since weakened. A second landfall is expected between Taizhou in Zhejiang and Ningde in Fujian on Tuesday afternoon or evening, according to China’s Ministry of Water Resources.

Full resumption of port operations is anticipated by Thursday, when conditions are expected to stabilise.

Several other ports across South China and the Yangtze River Delta have also suspended operations since Sunday, the source added.

In northern China, Dalian and Qingdao continue to offer good availability of both VLSFO and LSMGO. However, HSFO remains scarce in Qingdao. Tianjin is currently facing tight supply across all three fuel grades—VLSFO, LSMGO, and HSFO.

In Shanghai, VLSFO and HSFO remain in limited supply, while LSMGO stocks are relatively stable. Further south, availability varies: Fuzhou is experiencing restricted supply of both VLSFO and LSMGO, whereas Xiamen has sufficient VLSFO but limited LSMGO. In Yangpu and Guangzhou, prompt deliveries of both VLSFO and LSMGO remain challenging.

In Hong Kong, lead times for all fuel grades remain stable at around seven days. However, forecasts indicate adverse weather between 9–11 July, which could disrupt bunker deliveries.

Meanwhile, bunker operations at Taiwan’s Kaohsiung and Taichung ports resumed today after being suspended yesterday due to Typhoon Danas, according to another source. Currently, lead times at both Kaohsiung and Taichung are approximately 3–4 days for VLSFO and LSMGO. At other major Taiwanese ports, such as Hualien and Keelung, lead times are shorter—around two days.

In South Korea, LSMGO availability remains tight as more bunker buyers have shifted to Korean ports, where the grade is currently priced lower than in neighbouring Chinese ports. Busan’s LSMGO is now priced $16/mt below Zhoushan’s.

Lead times for LSMGO have widened significantly, now ranging from 4–14 days, up from 4–10 days last week. In contrast, availability for VLSFO has improved, with lead times shortening from 4–6 days to just 2–4 days. HSFO lead times have also eased, dropping from around five days last week to 2–4 days now.

However, bunker operations may be impacted by adverse weather across several ports. Ulsan and Onsan could see disruptions from 10–11 July, Busan from 8–14 July, Daesan and Taean from 11–12 July, and Yeosu from 11–14 July.

VLSFO supply remains robust at key Japanese ports such as Tokyo, Chiba, Yokohama, and Kawasaki. However, prompt availability is more limited in Osaka, Kobe, Sakai, and Mizushima, and remains particularly constrained in Nagoya and Yokkaichi.

LSMGO is generally well-stocked across the country, though securing prompt deliveries remains a challenge in several ports—including Osaka, Kobe, Sakai, Nagoya, Yokkaichi, and Mizushima. HSFO supply is steady overall, but prompt delivery is likewise restricted at these same ports.

In Oita, availability remains tight across all fuel grades.

Adverse weather is forecast to disrupt bunker deliveries at Thailand’s Koh Sichang and Laem Chabang ports on 9 July. In Vietnam, rough sea conditions are also expected to affect bunker operations in Ho Chi Minh on 10 July and again between 13–14 July.

Oceania

In Western Australia, VLSFO and LSMGO are readily available at Kwinana, Fremantle, and Port Kembla, with suppliers recommending lead times of 7–8 days.

In New South Wales, LSMGO supply remains steady in Sydney, though prompt deliveries of HSFO continue to face challenges.

Victoria’s ports—Melbourne and Geelong—have good availability of both VLSFO and LSMGO, but HSFO remains limited, particularly for prompt requirements.

In Queensland, VLSFO and LSMGO are well-stocked at Brisbane and Gladstone, with typical lead times of around seven days. However, HSFO availability in Brisbane remains tight.

Across the Tasman, VLSFO is sufficiently available in both Tauranga and Auckland. That said, bunker operations in Tauranga could be affected by adverse weather conditions forecast for 11–12 July.

South Asia

VLSFO supply remains tight across several Indian ports—including Mundra, Kandla, Mumbai, Tuticorin, Chennai, Visakhapatnam, Cochin, and Haldia—extending the supply constraints observed in recent weeks. LSMGO availability at most Indian ports continues to be handled on an enquiry basis.

The dock workers’ union has announced a one-day strike in Mumbai from 9–10 July, with plans to extend the action to Cochin thereafter. Cargo operations in Mumbai are unlikely to face major disruptions, as most terminals there are privately operated. However, operations at Cochin are expected to be affected, according to GAC Hot Port News.

Adverse weather is also set to hamper bunker activity at multiple Indian ports. Disruptions are forecast at Kandla and Sikka on 9 July, and at Visakhapatnam and Mumbai from 8–9 July.

In Sri Lanka, lead times for all fuel grades at Colombo and Hambantota have improved significantly, dropping to around two days from approximately six days last week. However, rough weather conditions expected in Colombo between 11–12 July could impact bunker operations.

Middle East

In Fujairah, VLSFO requires lead times of approximately 5–7 days, slightly improved from last week’s recommendation of around 6 days. Lead times for LSMGO and HSFO remain steady at about 5–7 days, showing little change compared to the previous week.

In Basrah, Iraq, both VLSFO and LSMGO are readily available, although HSFO supply remains limited. In Jeddah, Saudi Arabia, availability of both VLSFO and LSMGO is constrained.

At Egypt’s Suez port, stocks of all three conventional bunker grades, VLSFO, LSMGO, and HSFO, are nearly depleted. In Qatar’s Ras Laffan, the supply of VLSFO and LSMGO is currently tight.

Djibouti is facing significant supply pressure, with VLSFO and HSFO nearly out of stock, and LSMGO availability also limited.

On the other hand, Omani ports—including Sohar, Salalah, Muscat, and Duqm—continue to report stable LSMGO supply.

ENGINE: Americas Bunker Fuel Availability Outlook (3 July 2025)

Hurricane season disrupts bunkering in GOLA; HSFO availability improves in Balboa; first vessel berthed at new Bahia Blanca terminal.

RESIZED ENGINE Americas

The following article regarding bunker fuel availability in the Americas region has been provided by online marine fuel procurement platform ENGINE for post on Singapore bunkering publication Manifold Times:

  • Hurricane season disrupts bunkering in GOLA
  • HSFO availability improves in Balboa
  • First vessel berthed at new Bahia Blanca terminal

North America

Bunker fuel demand has seen a slight uptick in Houston, and recommended lead times for VLSFO and HSFO stand at 5-7 days.

LSMGO is more readily available and can be delivered within five days, a source said.

The hurricane season has begun in the US Gulf and will run through November.

Its onset has resulted in tropical depressions and storms, causing intermittent disruptions to bunker operations, especially around Bolivar Roads and the Galveston Offshore Lightering Area (GOLA) on the east coast.

In GOLA, bunker deliveries are being managed on a first-come, first-serve basis and remain subject to weather conditions.

Peninsula announced last month the expansion of its physical bunkering operations in GOLA. It will offer all main conventional grades – HSFO, VLSFO and LSMGO – along with biofuels.

Also, Coastal Bend LNG has plans to develop a 22.5 million mt/year LNG export facility on the Texas Gulf Coast. The facility will include up to five liquefaction trains of 4.5 million mt/year capacity each, LNG storage tanks and bunkering infrastructure.

Bunker demand in New York has remained static compared to the previous week, with spot premiums also seeing minimal movement so far, a source noted.

In terms of availability, the port is well stocked and can make prompt deliveries of VLSFO and LSMGO with lead times of 3-4 days.

HSFO requires longer lead times of around 5-7 days.

New York may also see high wind gusts between 3–6 July, potentially disrupting operations. While no backlog is reported, anchorage deliveries could be delayed due to limited barge availability.

Bunker demand is steady in Los Angeles and Long Beach. Fuel availability is good at both ports, and suppliers continue to recommend lead times of up to seven days.

The port of Los Angeles is seeing an increase in container volumes, one week ahead of the expiration of the reciprocal tariff pause for most countries—except China, where the deadline is about a month away.

According to the Port of Los Angeles, import volumes are projected to decline in the week of 6–12 July, with 108,557 TEU expected, a drop of 18.55% from the current week.

This comes after a strong performance during the week of 29 June–5 July, when volumes are estimated to reach 133,272 TEU, up 0.73% from the previous week and 17.25% higher than the same week last year.

The number of scheduled vessels is also set to fall from 26 this week to 21 next week, the port noted.

After 9 July, high import duties could come back into effect unless the US government delays or changes them. So far, the White House has left the door open to either raising, lowering, or postponing tariffs and has not confirmed its decision.

Montreal is expected to face disruptions from 3–6 July due to high wind gusts.

Barge operations are limited to daylight hours, which could lead to congestion. Delays are possible for anchorage deliveries due to bunker barge readiness issues.

Latin America and the Caribbean

Bunker fuel availability is good in Panama. In both Balboa and Cristobal, availability remains steady across all fuel grades, with recommended lead times of roughly four days.

HSFO availability has improved in Balboa after a recent resupply of the grade, a source said.

Balboa is forecast to experience thunderstorms from 3–6 July, which could impact operations.

Deliveries at the port are currently being carried out on a first-come, first-serve basis, with priority given to vessels with confirmed transit schedules through the Panama Canal. No bunker barge congestion is noted.

In Argentina’s Bahia Blanca port, calling costs have increased from 1 July, Antares Ship Agents informed.

The first vessel berthed at the new Oiltanking berth in the port last Saturday. The vessel SEAWAYS EAGLE berthed with the help of four tugs and lifted about 70,000 cbm of Medanito crude oil.

In Zona Comun, “availability and demand both appear to be normal,” a local supplier said. Lead times for VLSFO currently stand between 5-6 days.

The anchorage may be impacted by high wind gusts on 5 July.

Deliveries are done on a first-come, first-serve basis, and bunker operations could face delays if wind gusts exceed 20 knots.

Fuel availability is decent across Brazilian ports. Both VLSFO and LSMGO grades are available at Rio Grande and Rio De Janeiro, with recommended lead times of 3-4 days.

Port of Santos is facing congestion where wait times are higher and requires over five days for delivery, a source said.

Bunker fuel availability is good at key Colombian ports.

“VLSFO for $540/mt and LSMGO for $640/mt available at Santa Marta, Cartagena and Barranquilla with lead time of 3 days,” a bunker trader informed.
