According to WPB, Central Europe’s bitumen market is moving deeper into surplus as higher refinery output in Poland and the Czech Republic meets demand that has been slow to recover from the summer slowdown. The imbalance has pushed regional prices toward six-month lows and could increase competition for export markets as Polish suppliers seek additional outlets for available material.
Polish domestic truck bitumen was assessed at around €530/MT ex-works on September 4, its lowest level since March 13. Czech domestic truck prices were around €545/MT ex-works during the same period, reaching their weakest level since March 6.
The decline reflects a combination of sluggish demand and increased refinery availability. Higher bitumen production from Płock in Poland and Litvínov in the Czech Republic during the previous two months has added material to a market where road-paving activity has not recovered quickly enough to absorb the additional volumes.
More stable availability of Middle Eastern sour crude has also supported refinery operations in the region. Changes in crude availability are particularly relevant to bitumen because the type of feedstock and the way heavy fractions are processed can influence how much residual material ultimately becomes available for binder production.
Płock has now become an important variable for the next stage of the market. Planned maintenance started at the refinery on September 2 and includes work affecting crude distillation and hydrocracking operations.
Rather than necessarily reducing bitumen availability, the maintenance could result in more vacuum residue becoming available for binder production. Vacuum residue is an important feedstock for bitumen manufacturing, and changes in the amount directed toward upgrading units can alter the volume available for road-bitumen production.
This creates an unusual situation in which refinery maintenance could reinforce rather than relieve the existing surplus. If additional heavy residue is directed toward bitumen, Polish producers will need either stronger domestic consumption or additional export demand to absorb the resulting material.
Poland is already one of the major bitumen supply centres in Central and Eastern Europe. Production facilities at Płock, Gdańsk and Trzebinia serve domestic customers as well as international markets, giving Polish suppliers considerable reach across neighbouring countries.
Germany is one of the most logical destinations for additional Polish material because of its proximity and large road-construction market. Increased Polish availability could strengthen competition in eastern Germany, where transport distances from Polish production centres remain commercially manageable.
Romania is another potential outlet, particularly where infrastructure and road programmes sustain demand for paving-grade bitumen. Ukraine could also absorb part of the additional availability as infrastructure requirements continue to create demand for imported material, although actual flows will depend on transportation economics, border capacity and project activity.
Poland exported around 83,000 tonnes of bitumen during the first half of 2026, compared with approximately 100,000 tonnes during the same period of 2025 and 90,000 tonnes in the first half of 2024. The figures indicate that exports had been running below the previous two years before the latest increase in domestic availability.
That leaves room for a stronger export push during the remainder of the paving season. If inventories continue to build, suppliers may have greater incentive to compete for buyers in surrounding markets rather than allow excess material to remain at domestic production centres.
The Czech market could partially counter this pressure. Litvínov is expected to prioritize domestic requirements and reduce the amount available for export as Czech road demand gradually recovers from its summer slowdown.
Lower Czech export availability could absorb some of the regional impact of higher Polish production. Current supply conditions, however, indicate that the Polish increase could still be large enough to keep the broader Central European market well supplied.
For buyers, the surplus creates greater sourcing flexibility. Multiple supply options and weaker competition for available volumes improve negotiating conditions, while sellers face greater pressure to place material before seasonal road demand begins declining again.
The relationship between vacuum residue and bitumen production is particularly important in the current environment. Road bitumen is commonly produced from heavy residues remaining after crude distillation, and the amount of this material directed toward bitumen depends on refinery configuration, product economics and the availability of alternative processing routes.
Maintenance can temporarily change this balance. When certain upgrading units operate at reduced capacity, material that would otherwise undergo further processing can become available for alternative uses, including bitumen production.
That is why the Płock maintenance programme deserves attention from the European bitumen market. Its significance does not come simply from the fact that a refinery is undergoing maintenance, but from how that maintenance could change the internal flow of heavy refinery components.
The market is also entering a sensitive seasonal period. European road-paving activity can decline quickly as temperatures fall and weather conditions become less suitable for asphalt work, reducing the amount of time suppliers have to clear excess inventories.
If demand fails to strengthen before that seasonal decline begins, additional Polish supply could exert further pressure on nearby markets. Germany, Romania and Ukraine will therefore be important indicators of how successfully Polish producers can redistribute excess material.
Regional price differences will determine how far the product can economically travel. A lower ex-works price does not automatically make Polish bitumen competitive in more distant markets because transportation costs must be added before the material reaches the buyer.
For the asphalt industry, lower bitumen prices can provide some relief to material costs, particularly for contractors entering the final part of the paving season. The benefit will vary between markets because transportation expenses and local supply conditions can create significant differences between refinery and delivered prices.
A prolonged surplus could also affect purchasing behaviour. Buyers with sufficient storage and project visibility may delay commitments in anticipation of more competitive offers, adding another layer of pressure to a market already struggling to absorb supply.
Producers, meanwhile, must balance inventory management against the economics of alternative heavy refinery products. If bitumen values weaken too far relative to other outlets for residual material, the incentive to maximize binder production could eventually diminish.
The next several weeks will therefore provide a clearer indication of whether Central Europe is moving toward a sustained surplus or experiencing a temporary imbalance. Polish export volumes, Płock production, Czech domestic consumption and regional road activity will be among the most important indicators.
For now, the evidence points to abundant availability rather than shortage. Poland has more material entering the market, Czech supply remains substantial and the approaching end of the paving season gives producers a narrowing window in which to move inventories.
If additional vacuum residue becomes available from Płock as expected, the pressure could extend beyond Poland through stronger exports into neighbouring markets. Until demand catches up or refinery production adjusts, Central Europe is likely to remain one of the more competitively supplied bitumen markets heading into the final stage of the 2026 paving season.
