Petroleum products are the refined outputs of crude oil distillation, covering everything from heavy fuel oils used in power plants and marine engines to light distillates like naphtha and jet fuel. As a category, they sit at the intersection of energy security and industrial supply — every economy depends on a steady flow of refined products, and pricing tracks closely with crude benchmarks while carrying its own regional premiums and discounts (crack spreads). For traders, petroleum products are typically higher-volume, lower-margin deals compared to specialty chemicals, with liquidity concentrated around a handful of well-defined grades.
Grades & Specifications
- **Fuel Oil CST 180 / CST 380** — heavy residual fuel graded by viscosity (centistokes at 50°C); CST 380 is thicker and cheaper, used mainly for marine bunkering and power generation; CST 180 is easier to handle in colder climates. - **Naphtha** — a light distillate split into "light" (petrochemical feedstock, high paraffin content) and "heavy" (gasoline blending, reforming feedstock) grades. - **Kerosene** — used for heating and lighting in dual-fuel and illuminating grades; specification-driven by smoke point and flash point. - **Jet Fuel (Jet A-1)** — the international aviation turbine fuel standard (DEF STAN 91-091 / ASTM D1655), with tight freeze-point and thermal stability requirements — the least forgiving grade in this category for quality deviation. Buyers should always request the seller's typical assay or a recent Certificate of Quality (CoQ) for the specific parcel, since "CST 380" or "Jet A-1" describes a spec range, not a single fixed composition.
Quality Standards & Inspection
Fuel oils are typically tested against ISO 8217 (marine fuel specification, covering density, viscosity, sulfur, water content, and flash point). Jet fuel follows ASTM D1655 or the UK Def Stan 91-091, plus Joint Inspection Group (JIG) certification for the supply chain itself. Independent inspection at load port is standard practice — SGS, Intertek, Bureau Veritas, and Saybolt are the names buyers most commonly see on a Certificate of Quality and Certificate of Quantity. For fuel oil specifically, sulfur content is now a major compliance point post-IMO 2020 (0.50% m/m global sulfur cap for marine fuel, 0.10% in Emission Control Areas), and mismatched sulfur specs are one of the most common sources of cargo rejection.
Main Producing & Exporting Regions
The Middle East (Saudi Arabia, UAE, Kuwait) and Russia remain the largest exporters of fuel oil and naphtha, with large refining capacity built specifically for export markets. South East Asia (Singapore, Malaysia) is both a major refining/blending hub and a re-export trading center — Singapore in particular functions as the pricing and bunkering benchmark for the whole region. North Africa (Egypt, Algeria) supplies the European market due to proximity, and the United States (Gulf Coast refineries) exports significant volumes of naphtha and jet fuel, especially to Latin America and Europe.
Packaging & Logistics
Volumes below a few thousand MT move in ISO tank containers or flexi-tanks (for non-hazardous grades); anything cargo-scale moves in bulk parcel vessels chartered specifically for the deal, or as part-cargo on a product tanker. Road tankers handle the last-mile leg from port terminal to end buyer. FOB and CFR are the most common Incoterms for petroleum product deals — CIF appears when the buyer wants the seller to also arrange insurance. Typical laycan-to-discharge transit runs 5–20 days depending on the route (Middle East to Asia is short-haul; Middle East to Europe or the Americas is long-haul).
Key Contract Considerations
Because petroleum products are priced against a floating benchmark (Platts/Argus assessments plus a premium or discount), the SPA must lock the exact pricing formula, publication, and pricing window — not just "market price." Quality is usually settled by an independent inspector's result at load port (or discharge port, if agreed), with a tolerance band for minor deviations and a rejection/rebate mechanism for anything outside it. Demurrage terms, laytime, and the allocation of quality/quantity disputes to a named arbitration inspector are the clauses that cause the most disputes if left vague. ---
