Low-sulphur gasoil and the sulphur rules.

What we supply, how the ISO 8217 distillate grades compare, and which sulphur limit applies where you are heading.

Last reviewed 30 September 2026. Rules change: check your flag State and the sources below.

What we supply

We supply one product: ultra-low sulphur gasoil, with sulphur below 0.20 %. It is delivered ship-to-ship by our own vessel, at the dock or at anchor.

ISO 8217 no longer sets a sulphur figure for each grade. The buyer states the limit the fuel must meet, so tell us the limit you need when you request.

Sulphur limits

MARPOL Annex VI regulation 14. Our gasoil is highlighted.
Where	Limit	Since
Outside emission control areas	0.50 % m/m	1 January 2020
Inside emission control areas (ECAs)	0.10 % m/m	1 January 2015
SM Caribbean low-sulphur gasoil	Below 0.20 % m/m	–

Since 1 March 2020 a ship may not even carry fuel above 0.50 % for use, unless it has an approved equivalent such as a scrubber.

Schematic, not to scale and not for navigation. The ECA boundary is set by coordinates in IMO MEPC.1/Circ.755.

Heading west? The US Caribbean Sea ECA, around Puerto Rico and the US Virgin Islands, starts roughly 45 to 50 nautical miles west of Sint Maarten. Our gasoil is not for use inside it: change over to fuel at 0.10 % or below before you cross the boundary.

0.50 %sulphur limit

Outside any emission control area. The global limit applies, and our gasoil is below it.

Our gasoil is below 0.20 %, within the 0.50 % global limit.

ISO 8217:2024 distillate grades

The 2024 edition added DF grades, which may contain biodiesel (FAME) up to 100 %. The DM grades are expected to contain FAME only at a trace level, about 0.5 %. Trade names such as MGO or ULSD are labels, not specifications: ask for the grade and its limits.

Selected limits from ISO 8217:2024 Table 1, as summarised by CIMAC and suppliers. Check the standard for the full list.
Grade	Viscosity at 40 °C (mm²/s)	Density at 15 °C, max	Flash point, min
DMX	1.400 to 5.500	–	43.0 °C
DMA / DFA	2.000 to 6.000	890.0 kg/m³	60.0 °C
DMZ / DFZ	3.000 to 6.000	890.0 kg/m³	60.0 °C
DMB / DFB	2.000 to 11.00	900.0 kg/m³	60.0 °C

Litres to tonnes

Delivery notes state quantity in metric tonnes. For a quick estimate from litres:

Litres at 15 °CDensity at 15 °C (kg/m³)

10.14metric tonnes

An estimate: tonnes = litres × density ÷ 1,000,000. The delivery note uses the measured density and temperature-corrected volume.

Sint Maarten and Annex VI

IMO's treaty status list shows MARPOL Annex VI, the annex on fuel sulphur, as not applying to Sint Maarten as a jurisdiction. Yachts flagged in countries that apply Annex VI still carry its rules with them, including the sulphur limits, the delivery note and the fuel sample. We supply both with every delivery.
