French testing, inspection and certification firm Bureau Veritas recently provided Singapore bunkering publication Manifold Times a copy of its VeriFuel Fuel Quality Testing Q2 2026 Report which provides an overview of marine fuel quality, emerging trends, and compliance levels based on all tested bunker samples across its laboratories. The following is an overview of the report: VLSFO Global Quarterly Averages Global VLSFO quality indicators in Q2 2026 remain stable. Viscosity, density and cat fines have slightly increased compared to Q1 2026. The overall off-spec rate increased slightly to 1.5%, although still remaining within historical norms. Global Monthly Averages Monthly data for Q2 2026 show relatively limited variability across all key parameters. Viscosity increased progressively from April to June, while sulphur and sediment levels remained stable. Off-spec incidence declined throughout the quarter, suggesting an improvement in regards to ISO. Global Quarterly Pour Point Distribution The pour point distribution in Q2 2026 remains largely consistent with previous quarters. Majority of samples continue to fall within low temperature ranges (≤ 21 °C) while cases at or slightly above limit are very limited. Global Quarterly Out-of-Spec Parameters Sulphur, water, sediments and cat fines continue to represent the primary causes of VLSFO non-compliance in Q2 2026 while the ratio of all properties have increased compacted to Q1 2026. VLSFO 0.50% Port Averages Regional variations remain evident across fuel properties. Elevated Al+Si levels continue to be observed in ports such as Port Klang and Singapore, while sediment-related concerns were identified in several European locations. Sulphur remains the most commonly reported cause of non-compliance across major bunkering hubs. Sediments by Quarter The percentage of fuels exceeding the sediment threshold (≥0.07% m/m) increased compared to Q1 2026. While most fuels remain within ISO 8217 limits, the rising trend hig
