Poland and Romania will not expand transit capacity for Ukrainian grain, according to UkrAgroConsult, deepening the logistical squeeze on Kyiv as it searches for export routes outside the Black Sea.

The refusal comes as Ukraine continues to ship agricultural commodities through EU "solidarity lanes" established in 2022. Those routes — a combination of road, rail and Danube barge corridors — have absorbed a major share of Ukrainian grain, oilseed and processed-product volumes since Russia closed portions of the Black Sea to commercial traffic.

Why are Warsaw and Bucharest blocking expansion?

Transit friction has run hot since mid-2023, when the European Commission lifted bloc-wide restrictions on Ukrainian grain imports but Poland, Hungary and Slovakia maintained unilateral bans. Those national measures formally expired in September 2023, yet political pressure from domestic farmer lobbies has kept restrictions alive through licensing, customs delays and protest action.

For Romania, the Black Sea port of Constanta has served as the main outlet for Ukrainian grain moving by river and rail, handling a record share of Ukraine's overland exports in 2023 and 2024. Romanian officials have signaled that the port is running close to capacity, with further dredging and silo investment required to lift throughput.

Polish border crossings have seen repeated blockades by farmer organizations. Demonstrations in 2023 and 2024 targeted what producers describe as unfair price competition from Ukrainian supplies. The governing coalition in Warsaw has largely aligned with those demands, leaving transit permits and phytosanitary clearances unpredictable for shippers.

What does the refusal mean for Ukrainian margins?

Every tonne rerouted overland costs more than a Black Sea shipment. Rail tariffs, truck queues at the Ukrainian-Polish border and Danube barge fees have widened the basis between Ukrainian interior prices and FOB Black Sea equivalents by double-digit dollars per tonne in peak weeks.

A sustained refusal to scale transit forces Kyiv to lean more heavily on the remaining Black Sea corridor, where war-risk insurance premiums and security costs add another layer of expense. The combined effect has compressed farm-gate margins for Ukrainian producers of corn, wheat and sunflower oil — crops that drive a large share of national farm revenue.

What comes next?

Ukraine's grain and oilseed exports for the 2024/25 marketing year will hinge on whether the European Commission brokers a new arrangement covering both imports and transit, or whether bilateral negotiations with Warsaw and Bucharest produce incremental capacity gains. Brussels talks during 2024 produced a partial licensing compromise covering four sensitive commodities, but extension to broader transit volumes has stalled.

Analysts at UkrAgroConsult and peer consultancies will watch the next EU agriculture council meeting for any signal that member states will reopen the transit question. Until then, shippers should expect tighter capacity at Polish and Romanian crossings and continued reliance on the remaining Black Sea lanes and the Danube route via Constanta.
