According to WPB, the global bitumen industry entered the second week of July 2026 with a combination of refinery shutdowns, restricted processing capacity and severe maritime uncertainty. The suspension of major Russian refining sites, a scheduled turnaround at China’s Shenghong complex and continuing security concerns in the Strait of Hormuz have created a more difficult operating environment for suppliers across Europe, Asia, the Middle East and Africa. These events do not automatically indicate an immediate worldwide shortage of paving-grade bitumen. They do, however, reduce the amount of spare refinery capacity available at a time when road construction programs, seasonal demand and shipping constraints require reliable production and predictable delivery schedules. For the Middle East, the main concern is no longer limited to refinery output. Access to vessels, insurance cover, safe passage and the timing of cargo movements through Hormuz have become equally important factors in the physical availability of bitumen.
Russia’s Omsk refinery became the most significant refining disruption of the period after a Ukrainian drone attack damaged key processing infrastructure. The Gazprom Neft-operated facility, located in western Siberia, is Russia’s largest oil refinery and normally processes approximately 22 million tons of crude oil annually. Two of its major crude distillation units were taken out of service after the attack. CDU-10, which accounts for roughly 38% of the site’s processing capacity, was damaged by fire, while CDU-11, representing another substantial share of throughput, was shut after damage to refinery networks. The loss of these units temporarily removed most of the refinery’s primary processing capability.
Omsk is best known for producing gasoline, diesel, jet fuel and other mainstream petroleum products, but the shutdown is also relevant to the bitumen sector. Bitumen production depends on the availability of vacuum residue and other heavy refinery streams generated after atmospheric and vacuum distillation. When primary processing is halted, the volume of residue available for further conversion or bitumen manufacture falls accordingly. Even where a refinery prioritizes motor-fuel production during its restart, bitumen output may recover later because operators commonly allocate limited feedstock toward products considered more urgent for domestic energy security.
The consequences could extend beyond the direct loss of Omsk supply. Russia is already dealing with reduced motor-fuel production following repeated attacks on its refining network. Domestic shortages have prompted export restrictions and greater attention to internal fuel availability. Under these conditions, refiners may be instructed to maximize gasoline and diesel output after restarting units. Such decisions can reduce the amount of heavy residue retained for bitumen production, particularly if conversion units are used more intensively to upgrade heavier material into lighter fuels. The bitumen industry may therefore experience a longer period of constrained availability than the headline duration of the refinery shutdown suggests.
The Saratov refinery added a second major disruption when its only primary crude-processing unit was damaged in another drone attack. The Rosneft-owned plant stopped processing crude after the CDU-6 unit, with a capacity of about 20,000 tons per day, was affected. Saratov processed approximately 5.8 million tons of crude in 2024 and produces gasoline, diesel and fuel oil. As the refinery relies on a single principal crude-distillation unit, damage to that unit can halt the entire flow of intermediate products needed by downstream operations.
Saratov’s importance to the bitumen sector is linked mainly to its production of heavy refinery fractions. Fuel oil and vacuum residue can be directed toward several competing uses, including marine fuel blending, power generation, further refining and bitumen manufacture. When processing stops, the loss is therefore not confined to one finished product. It removes a portion of the heavy-feedstock pool serving western Russia and nearby markets. Repeated interruptions at Saratov during 2026 also raise concerns about operating continuity, maintenance requirements and the reliability of future supply commitments.
Other Russian facilities must also be included in the wider assessment. The NORSI refinery was halted following a drone strike in late June, while the Moscow refinery is expected to remain offline for an extended period after substantial damage from earlier attacks. The Moscow site was reported to face an outage lasting at least several months. In addition, attacks were reported at the TANECO and TAIF-NK refining complexes in Nizhnekamsk. Public information has not established that every strike resulted in a complete or prolonged shutdown, but the concentration of incidents across multiple facilities is important.
The cumulative issue is larger than the loss of output from any single refinery. Russia’s refining system is being required to redistribute crude, intermediate feedstocks and finished products while several plants undergo repairs or operate below normal capacity. Rail logistics, storage availability and regional fuel obligations will determine where remaining products are sent. Bitumen may receive lower priority than gasoline, diesel and aviation fuel, particularly during the summer driving season. Exporters relying on Russian-origin bitumen, fuel oil or heavy blending components may consequently face inconsistent loading programs, revised contract volumes or longer lead times.
China is dealing with a different type of outage. Shenghong Petrochemical began a planned turnaround at its integrated refining and petrochemical complex in Lianyungang, Jiangsu province, from late June. The complex has annual crude-processing capacity of approximately 16 million tons and is expected to remain under scheduled maintenance for a net period of around 45 days. Several associated units may also be taken offline according to maintenance requirements.
Unlike the Russian shutdowns, the Shenghong turnaround was announced in advance and is not connected to physical damage or military action. Its significance lies in timing and scale. The maintenance removes a large volume of Chinese refining capacity during the same period that Russian plants are facing unplanned outages. Shenghong is highly integrated with petrochemical manufacturing, and its product configuration is not centered solely on bitumen. It would therefore be inaccurate to treat the entire 16 million tons of capacity as direct bitumen supply. Nevertheless, the shutdown reduces regional processing flexibility and limits the complex’s ability to supply heavy streams, blend components and substitute products during a period of disruption elsewhere.
Chinese refiners frequently adjust production according to margins, crude grades, domestic demand and government policy. When one large complex is offline, surrounding facilities may raise throughput, but they may also favor transport fuels or petrochemical feedstocks rather than road bitumen. The result for the bitumen market depends on whether other Chinese refineries increase production and whether coastal inventories are sufficient to meet construction demand. The timing of Shenghong’s restart will therefore be closely watched by buyers in eastern and southern China, particularly if weather conditions allow roadwork to accelerate later in the quarter.
The Strait of Hormuz presents a separate but closely connected risk. Tanker movements through the waterway slowed sharply after renewed attacks on commercial vessels. Several oil and gas tankers turned back from attempted passages, while other ships waited outside high-risk areas or selected routes closer to Oman. Traffic has continued, but passage cannot currently be described as fully normal. Shipowners must assess naval guidance, crew safety, vessel exposure, insurance conditions and the availability of emergency support before accepting voyages.
For bitumen trade, these restrictions are especially serious because the sector relies on specialized tankers and heated cargo systems. The pool of suitable vessels is much smaller than the general crude-tanker fleet. When owners withdraw tonnage from the Gulf or demand stronger security arrangements, replacement capacity cannot be secured quickly. Delays also have operational consequences: bitumen must remain within controlled temperature ranges, terminal storage can fill, and refinery loading schedules may need to be revised when vessels fail to arrive on time.
Iran, Bahrain, Iraq and other Gulf-linked suppliers serve buyers in India, East Africa, Southeast Asia and other international destinations. A serious reduction in Hormuz traffic could delay Iranian and Bahraini cargoes and complicate regional transshipment arrangements. Iraq has export options outside the strait for some petroleum flows, but bitumen logistics remain dependent on available terminals, road transport and suitable marine connections. The United Arab Emirates has infrastructure outside Hormuz for certain crude exports, although this does not provide a complete substitute for regional bitumen movements.
The combined refinery and maritime situation is unlikely to produce an identical outcome in every market. Russia’s difficulties are most relevant to domestic and neighbouring supply, while Shenghong’s maintenance concerns Asian processing capacity. Hormuz is a broader logistical risk affecting Gulf-origin cargoes and shipping confidence. Together, however, these developments reduce the number of dependable alternatives available to international buyers.
Importers may respond by dividing purchases among several origins, increasing safety stocks and allowing more time between nomination and delivery. Suppliers with access to storage outside high-risk areas may gain commercial advantages, while refineries capable of maintaining steady production could secure longer-term business. Buyers should also examine contractual clauses covering delays, vessel substitution, security incidents and force majeure. A cargo that exists at the refinery is not commercially available if a ship cannot reach the loading terminal or obtain acceptable insurance.
The next stage will depend on three practical developments: the speed of repairs at Omsk and Saratov, the progress of the Shenghong turnaround and the restoration of dependable commercial passage through Hormuz. A rapid Russian restart, timely completion of maintenance in China and a sustained reduction in maritime attacks would ease current concerns. Further damage, delayed repairs or additional tanker incidents would create a more serious supply problem for the bitumen industry during the remainder of the third quarter.
