Rotterdam’s B30‑VLSFO bunker price rose by $11/mt over the past week while the Dutch port’s conventional VLSFO climbed $30/mt, narrowing the B30 premium to $155/mt, sources indicated on 25 October 2026.
The smaller advance for the biofuel blend compared with the conventional fuel left the gap between the two grades $19/mt tighter than seven days earlier. The report attributes the relatively muted B30 movement to lower feedstock costs, which limited the biodiesel-linked product’s ability to keep pace with conventional VLSFO.
Market moves
Over the week under review the conventional VLSFO increase of $30/mt outpaced the B30 rise, compressing the premium that ships pay for the lower‑carbon blend. The narrowing of that premium to $155/mt is a direct arithmetic outcome of the differing weekly gains recorded in Rotterdam.
The report’s figures describe a short‑term change in the spread rather than a structural shift, and they underline how feedstock pricing can temper B30’s response to wider bunker market dynamics. Sources noted the specific week‑on‑week changes without extending into longer‑term trends beyond the reported period.
Low‑carbon credits and supply incentives
The item also observed that Dutch suppliers can generate ZRE A tickets when selling low‑carbon fuels, and that these tickets may be traded. The existence of that mechanism was reported in the same piece, and it sits alongside the price movements as a factor in the commercial calculus for sellers of blended fuels.
The report did not supply further detail on traded values for ZRE A tickets or on how purchasers and ship operators are adjusting their procurement in response. It confined its coverage to the recent price movements in Rotterdam and the statutory possibility for suppliers to issue the tickets.
Taken together, the reported numbers show a week in which conventional VLSFO made the larger move and reduced the cost differential for B30 in Rotterdam. The source framed the outcome principally as the result of lower feedstock costs limiting the biofuel blend’s price gain while conventional fuel rose more sharply, producing the $19/mt narrowing of the premium to $155/mt.
Those figures provide a concise snapshot for market participants monitoring low‑carbon fuel economics in one of Europe’s major bunkering centres. reports’s item of 25 October 2026 set out the weekly changes and the regulatory context for ZRE A tickets as presented above.
