Rotterdam’s biofuel bunker is showing signs of softening after a weekly correction in feedstock-linked prices, according to a market briefing published on 1 November 2026.

The report from sources noted that Rotterdam’s B30-VLSFO, quoted as POMEME, fell by $36 per tonne over the past week. In the same interval the port’s conventional VLSFO rose by $23 per tonne, narrowing the premium for the B30 blend to $96 per tonne.

Prima Markets’ ARA UCOME and POMEME barge prices were cited in the briefing as key indicators of feedstock sourcing costs. The brief account linked the retreat in the B30 marker to the softer feedstock indicators, signalling that lower raw-material costs have weighed on the biofuel blend.

The movement altered the relative economics between the two grades. Where B30 previously carried a wider margin over conventional VLSFO, the combined moves in both markets reduced that gap by $59 per tonne in a single week.

Feedstock indicators and bunker pricing

Industry price feeds such as ARA UCOME and POMEME barge assessments are used to gauge the upstream costs of blending bio-derived components into marine fuels. The reports account presented both as relevant measures of the underlying cost base that can feed through to bunker quotations.

With those indicators softer in the latest update, the connection to a lower B30 quote at Rotterdam was drawn explicitly in the briefing.

Market implications for buyers and sellers

A narrowing premium between B30 and conventional VLSFO can influence procurement choices for operators weighing blend premiums against compliance and sustainability goals. The report’s figures show the premium is now $96 per tonne, a figure that reflects changed relative economics over the most recent week.

Traders and fuel suppliers monitoring ARA UCOME and POMEME barge levels will likely treat shifts in those assessments as advance signals for blend pricing, as the reports note suggested.

The weekly moves recorded in the briefing provide a snapshot rather than a long-term trend. The account confined itself to the most recent week, reporting a $36 per tonne fall for B30 POMEME and a $23 per tonne rise for conventional VLSFO in Rotterdam.

This short, data-focused update serves as a reminder of how feedstock cost dynamics underpin biofuel blend pricing within bunkering hubs such as Rotterdam. The reports item dated 1 November 2026 presented those points in its market summary.

Taken together, the reported shifts show how quickly the premium paid for a biofuel blend can compress when raw-material assessments move, with immediate consequences for pricing differentials in the bunkering market.

Short factual summary

  • Rotterdam B30-VLSFO (POMEME) down $36/mt week on week.
  • Rotterdam conventional VLSFO up $23/mt in the same period.
  • B30 premium over conventional narrowed by $59/mt to $96/mt.

The reports briefing deployed Prima Markets’ ARA UCOME and POMEME barge prices as reference points for feedstock sourcing costs, and used those references to explain the recent adjustment in Rotterdam’s B30-VLSFO quotation.
