Key Specifications
Coastal cargo vessels, tugs, dredgers, offshore support vessels and other craft operating on domestic Indian voyages that are not eligible for duty-free foreign-going bunker supply.
Duty-Paid vs Duty-Free — Why HFHSD Exists
The customs position
When a foreign-going vessel bunkers in India, the supply is treated as a deemed export and is exempt from customs duty — the fuel leaves Indian waters. A vessel on a coastal or domestic voyage is not exporting the fuel; it consumes it within India. That supply is therefore duty-paid, and HFHSD is the grade sold on that basis.
Same fuel, different fiscal treatment
Technically, HFHSD is high speed diesel with a high flash point suitable for marine engines — comparable distillate quality to marine gas oil. The practical distinction a coastal operator cares about is not the chemistry but the duty and documentation: HFHSD arrives duty-paid with the associated GST and paperwork already accounted for.
High flash point
Standard automotive high speed diesel has a lower flash point than marine safety practice prefers. The "high flash" HFHSD variant meets the raised flash-point requirement for carriage and use aboard vessels, reducing onboard fire risk in machinery spaces.
Documentation
Coastal bunker supply carries its own invoicing and GST treatment distinct from duty-free foreign-going stems. Seven Ocean handles the correct duty-paid documentation so the delivery is clean for a coastal operator's records.

Frequently Asked Questions
What does HFHSD stand for?
High Flash High Speed Diesel — a high speed diesel with a raised flash point for safe carriage and use aboard vessels, supplied duty-paid for coastal Indian operations.
How is HFHSD different from MGO or LSMGO?
The fuel is comparable distillate quality. The real difference is fiscal: foreign-going vessels bunker duty-free as a deemed export, while coastal vessels on domestic Indian voyages take duty-paid fuel. HFHSD is that duty-paid grade.
Which vessels take HFHSD?
Coastal and domestic-trade craft operating within Indian waters — coastal cargo ships, tugs, dredgers and offshore support vessels that are not eligible for duty-free foreign-going supply.
Is HFHSD available outside India?
No. It is a coastal Indian supply grade tied to Indian customs treatment. For international ports, distillate is supplied as MGO or LSMGO.
