01 Product
HSFO Supply
ALGHAF MARINE FZCO supplies HSFO as bulk residual marine fuel for ship operators, bunker buyers, distributors and qualified traders. Programs are evaluated cargo by cargo. Non-sanctioned origin is available where the destination and compliance structure require it.
After IMO 2020 this is primarily a scrubber residual: high sulfur is acceptable only where the vessel’s exhaust-gas cleaning and the destination rules allow it. Non-sanctioned origin is available where the destination and compliance structure require it.
What Is HSFO?
HSFO — high sulfur fuel oil — is the residual bunker category used after IMO 2020 mainly on vessels with approved exhaust-gas cleaning, or in applications that still accept high-sulfur residual fuel. Market language often pairs HSFO with 380 CST fuel oil, but CST is viscosity, not sulfur.
Buyers searching HSFO supplier, HSFO exporter, buy HSFO or bulk HSFO supplier should still state sulfur, viscosity and the ISO 8217 grade if a marine grade is required. This page covers the HSFO category. The ISO grade sheet is RMG 380.
Buyers using legacy RFQ terminology may also refer to D6 Virgin Fuel Oil or Mazut M100, subject to specification. Those labels are not ISO 8217 marine grades and are not substitutes for a contracted HSFO / RMG 380 stem.
02 Specification
HSFO Specifications
HSFO is a sulfur category, not one ISO grade. The table below is the typical residual discussion set when the RFQ is HSFO 3.5% / 380 CST and the buyer maps it toward an RMG 380-style marine residual. SPA and cargo CoA govern. This is not a standing Alghaf analysis.
| Parameter | Typical / discussion limit |
|---|---|
| Sulfur | High-sulfur residual; typically discussed up to 3.5% mass for scrubber programmes |
| Viscosity at 50 °C | Up to 380 mm²/s (380 CST) where that viscosity is requested |
| Density at 15 °C | Typically discussed up to 991.0 kg/m³ where an RMG 380-style residual is mapped |
| Flash point | min 60 °C (ISO residual discussion) |
| Water | typically discussed max 0.50% vol |
| Aluminium + silicon | typically discussed max 60 mg/kg (cat fines) where ISO residual is mapped |
| Vanadium | typically discussed max 350 mg/kg where RMG 380 is mapped |
| Sodium | typically discussed max 100 mg/kg where RMG 380 is mapped |
| Marine grade | ISO 8217 residual grade only if named in the SPA (often RMG 380) |
HSFO 3.5% and 380 CST Fuel Oil
HSFO 3.5% names sulfur. 380 CST names viscosity at 50 °C. A cargo can be HSFO 3.5% without being 380 CST. Cat fines (Al+Si) matter on residual bunkers even when sulfur is accepted on a scrubber vessel. Where RMG 380 is the required marine grade, use the RMG 380 product sheet.
HSFO vs VLSFO
VLSFO is the 0.50% sulfur IMO 2020 compliant residual option for vessels that do not burn HSFO on scrubbers. HSFO remains the high-sulfur residual stream. See VLSFO 0.5% marine fuel.
HSFO vs RMG 380
RMG 380 is a named ISO 8217 residual grade. HSFO is the sulfur category. An HSFO 380 CST enquiry often lands on RMG 380, but only if that grade is written into the SPA. Use this page for HSFO / high sulfur fuel oil / HSFO bunker fuel search intent. Use the RMG 380 sheet for the ISO grade.
03 Origin
Non-Sanctioned Origin HSFO
Non-sanctioned origin HSFO is available for selected destinations and vessel/charterer compliance requirements. Origin is transaction-specific. ALGHAF MARINE FZCO does not treat Fujairah, Rotterdam, Singapore or Black Sea execution as proof of origin.
Final origin is confirmed commercially in the offer, SPA and cargo documents after compliance review. No unverified refinery or producer claim is used.
04 Delivery
HSFO FOB & CIF Supply
HSFO FOB Supply
HSFO FOB may be evaluated from the residual loading point available for the cargo programme. Viscosity (often 380 CST at 50 °C), sulfur (typically discussed up to 3.5%) and cat-fines limits sit in the SPA — they are not implied by the word HSFO.
HSFO CIF Supply
HSFO CIF may be evaluated to the buyer’s nominated destination. The indication reflects specification, hub, freight, insurance and window.
HSFO STS / Bunker Supply
STS or bunker stems may be evaluated at approved locations where cargo allocation, vessel compatibility and operational approvals allow.
HSFO Supply Hubs
Transaction-specific execution may be arranged through UAE / Fujairah, ARA / Rotterdam, Mediterranean / Egypt, Southeast Asia / Singapore OPL, Black Sea and other approved locations. HSFO supplier Fujairah, HSFO UAE, HSFO Rotterdam, HSFO ARA, HSFO Singapore and HSFO Mediterranean are enquiry languages — not published tank lists.
05 Price & enquiry
HSFO Price
Current pricing depends on specification, quantity, supply hub, delivery basis, destination and shipment window. No invented HSFO FOB price or HSFO CIF price per MT is shown here.

HSFO frequently asked questions
What is HSFO?
HSFO means high sulfur fuel oil: a residual marine fuel category typically associated with sulfur up to about 3.5% mass. It is a sulfur class, not a single ISO 8217 grade. Contractual viscosity, density and other limits are confirmed in the SPA and cargo-specific CoA.
What is the current price of HSFO?
HSFO price is transaction-specific. It depends on specification, quantity, origin, supply hub, Incoterm, destination and shipment window. ALGHAF MARINE FZCO does not publish a standing HSFO dollar-per-MT offer on this page. Request a commercial indication after qualification. Market context is available on the HSFO 380 CST and HSFO 3.5% history series.
What are the typical specifications of HSFO?
Typical HSFO 3.5% / 380 CST discussion covers sulfur up to about 3.5% mass, viscosity up to 380 mm²/s at 50 °C, density often discussed up to 991 kg/m³, flash point min 60 °C, water typically max 0.50% vol, and cat fines (Al+Si) typically max 60 mg/kg where an ISO residual such as RMG 380 is mapped. SPA and cargo CoA govern. This is not a standing CoA.
Is non-sanctioned origin HSFO available?
Yes. Non-sanctioned origin HSFO is available for selected cargo programs, subject to specification, allocation, destination and compliance review. Final origin is confirmed commercially for the transaction and is not implied by the execution hub.
Do you supply HSFO FOB?
Yes. HSFO FOB may be evaluated from the residual loading point of the cargo programme. Viscosity (often 380 CST at 50 °C), sulfur (typically discussed up to 3.5%) and cat-fines limits sit in the SPA — they are not implied by the word HSFO.
Do you supply HSFO CIF?
Yes. HSFO CIF supply may be evaluated to an approved destination. Pricing reflects specification, origin, freight, insurance, quantity, destination and shipment window.
Which supply hubs are available for HSFO?
Transaction-specific execution may be arranged through UAE / Fujairah, ARA / Rotterdam, Mediterranean / Egypt, Southeast Asia / Singapore OPL, Black Sea and other approved locations. Hub listing is not a claim of physical stock at those ports.
What is the difference between HSFO and RMG 380?
HSFO describes the high-sulfur residual category. RMG 380 is an ISO 8217 residual marine grade commonly associated with viscosity up to 380 cSt at 50 °C. An HSFO cargo may be offered against RMG 380 where that grade is contracted, but the two terms are not automatic synonyms.
How can I request a commercial offer for HSFO?
Provide required sulfur and viscosity, quantity, destination, FOB / CIF / STS, shipment window and buyer company details. Following qualification, ALGHAF MARINE FZCO can issue the applicable commercial indication.
