Classification society DNV GL on Tuesday (18 December) provided the following update to shipowners and managers:

This statutory news covers vital information from the Chinese Ministry of Transport: introduction of a 0.5% sulphur limit for ships entering China’s coastal waters, and updated NOx regulations for imported ships engaged in domestic trade. Both regulations will enter into force on 1 January 2019.

To improve the quality of shipping and promote the environmentally friendly development of water transport within China, the Chinese Ministry of Transport published new requirements on 6 December 2018 for air pollution in Chinese coastal waters:

1. 0.5% sulphur limit from 1 January 2019 
From 1 January 2019, all ships entering China’s coastal waters must use fuel with a maximum sulphur content of 0.5% m/m. The coastal waters are illustrated in figure 1 (appendix in PDF version of article), and coordinates are listed in the document published by the Chinese Ministry of Transport (see reference below). A carriage ban for fuel oils containing more than 0.5% sulphur will be enforced for all ships without an exhaust gas cleaning system (EGCS, or scrubber) starting from 1 March 2020, thus being in line with global IMO sulphur regulations. 

From 1 January 2020, even stricter requirements will apply to ships entering inland waterways, including the Yangtze River and Xijiang River (western part of Pearl River), where a maximum 0.1% sulphur content will be allowed. From 1 January 2022, the 0.1% limit will also apply to the domestic area of Hainan Island. 

For ships undergoing a conversion, which includes the installation of EGCSs in Chinese dockyards, should communicate with the Chinese Maritime Safety Administration if fuel oils with a higher sulphur content can be used during the commissioning test of the EGCS. 

China will further evaluate the situation of using 0.1% sulphur fuel and will determine whether to implement the 0.1% sulphur limit in all coastal waters (not only the rivers) from 1 January 2025. 

2. Updated regulations on NOx emissions for ships in domestic trade
In the past, DNV GL published a statutory news covering requirements for second-hand vessels involved in Chinese domestic transport (see DNV GL Technical and Regulatory News No. 10/2018). 

Further details to this regulation are now been made available. 

It is now confirmed by the Chinese Ministry of Transport that all diesel engines installed on board an imported ship, which is engaged in domestic trade, need to comply with the IMO Tier II emission limits, i.e. main and auxiliary engines. The new NOx regulations are applicable for diesel engines installed on either:
Imported vessels (acquired second-hand from international owners) or Chinese-flagged vessels which are only involved in Chinese domestic transport (either coastal or inland).

These vessels are required to comply with the IMO Tier II emission limits. This limitation applies to vessels imported after 1 September 2018 and to vessels converted to be engaged in domestic trade only after 1 September 2018. The NOx emission regulations cover vessels operating within domestic waters (see figure 1 in PDF version of article).

The only means of acceptance criteria for this requirement are valid Engine International Air Pollution Prevention (EIAPP) certificates. Other (voluntary) statements of compliance will not be accepted.

There are basically three ways to comply:

  1. Engine already fulfils Tier II level, but EIAPP currently only shows certification according to Tier I: 

    In this case, a new Tier II engine group can be established based on paperwork. The responsible engine manufacturer should be contacted. 
     

  2. Engine does not fulfil Tier II, but by changing some settings such as injection or valve timing, it can be incorporated into an already approved Tier II group: 

    New settings to be fit by the engine manufacturer; new NOx Technical file needs to be prepared with the new settings, including a final parameter check by DNV GL on board the ship; issuance of EIAPP (Tier II). 
     

  3. Engine does not fulfil Tier II and parts need to be changed: On-board emission test according to test bed requirements of NOx Technical Code. After successful emission testing of an emission group, the NOx Technical File and EIAPP need to be prepared. This option might not be feasible, as in most cases it is cumbersome to fulfil the strict requirements of test bed conditions at an on-board emission test.

Recommendations

  1. 0.5% sulphur limit
    All ships operating in Chinese coastal waters are recommended to strictly follow the early implementation of the 0.5% sulphur content limit in fuel oils starting from January 2019.
  2. NOx requirement for import vessels
    If it is intended to sell a ship to a Chinese domestic owner and the vessel was keel laid before 1 January 2010, it might be a challenge to convert some diesel engines to the Tier II emission limits, without a conversion. Some possible scenarios are outlined in this statutory news.

Alkagesta highlights key insights of Malta bunkering market in 2026

In an article published on Alkagesta Market Insights, Darren Lee Axisa, Malta Country Manager of Alkagesta, on Monday (20 July) discussed the key trends influencing Malta’s bunkering market and the factors that will determine Malta’s long-term competitiveness as a regional bunkering hub: 

Malta’s bunkering and energy market is moving through a period of structural adjustment. The disruptions that defined the first half of 2026 have accelerated shifts in product demand, terminal strategy, and the competitive dynamics of one of the Mediterranean’s most strategically positioned bunkering hubs. For Alkagesta, whose storage footprint on the island approaches 300,000 cubic metres, the period has tested operational flexibility while reinforcing the value of diversified infrastructure access.

A Market Shifting in Two Directions

Malta’s broader economy has remained resilient — GDP growth reached 3.9% in Q1 2026 — but the bunkering market has undergone a significant product mix shift, the roots of which predate the current geopolitical disruption.

The Mediterranean Emission Control Area, which came into force on 1 May 2025, triggered an immediate and measurable realignment in fuel demand across the region. VPS data covering the first six months post-ECA implementation shows that across the top ten Mediterranean bunkering ports, VLSFO volumes fell 23%, MGO more than doubled, ULSFO quadrupled, and biofuels increased fivefold. In Valletta specifically, the shift was even more pronounced: VLSFO dropped 57% from 111,641 mt to 47,732 mt, while MGO volumes more than tripled from 33,299 mt to 103,445 mt, and ULSFO rose from 2,821 mt to 34,535 mt over the same period.

This structural rotation has been further accelerated by the broader regulatory environment. FuelEU Maritime and EU ETS requirements are pushing shipowners toward cleaner, verifiable fuel options at every port call — a direction Alkagesta had already positioned itself ahead of, having been among the first movers in the Mediterranean to support the transition to 0.1% sulphur fuel oil following the ECA’s introduction.

Layered on top of this regulatory shift has been a period of reduced terminal capacity affecting bunkering market availability across the island. Fuel oil volumes dropped roughly 35% year-on-year between January and May 2026, falling from approximately 382,000 mt in 2025 to 247,000 mt. DMA demand moved sharply in the opposite direction, rising from around 150,000 mt in January to April 2025 to 247,000 mt over the same period in 2026 — a trend consistent with both the ECA-driven product mix shift and the disruption to heavier fuel availability during the constrained period.

NorthStandard issues operational guidance for vessels entering ECAs

Jordan Hatch, Loss Prevention Executive, issued guidance for vessels operating in Emission Control Areas (ECAs).

Jordan Hatch, Loss Prevention Executive of global marine insurer NorthStandard, on Thursday (2 July) issued guidance for vessels operating in Emission Control Areas (ECAs):

The IMO addresses air pollution through MARPOL Annex VI, regulating the emissions of sulphur oxides (SOx), nitrogen oxides (NOx), and particulate matter from ships.

NOx requirements set limits on emissions from marine diesel engines through certification and tiered standards, whilst SOx regulations limit the sulphur content of fuel used onboard ships.

On 1 January 2020, the global sulphur limit for marine fuel was reduced from 3.50% to 0.50% by mass (m/m). However, some areas, known as SOx Emission Control Areas (ECAs), enforce stricter limits of 0.10% sulphur content. There are also dedicated NOx ECAs which impose tighter NOx emission standards for marine engines, particularly on newer vessels.

To meet the stricter SOx limits, ships must ensure they are burning compliant 0.10% sulphur fuel before entering an ECA. If a vessel is changing over from a 0.50% sulphur fuel, this requires a ship-specific calculation based on system volume, sulphur content, and current consumption to determine changeover time. Fuel changeover details, including quantities, date, time, and position, must be logged. Switching back to higher sulphur fuel should only begin after exiting the ECA.

To meet NOx requirements, vessels must demonstrate that their marine engines are certified to the applicable emission tier, and that they continue to operate within those limits through proper maintenance of combustion-related components.

Local Requirements

Some countries apply stricter local requirements in addition to MARPOL Annex VI. For example, Türkiye and Iceland have introduced a 0.10% sulphur limit in their territorial waters, while China has established its own dedicated ECAs.  

Members should check all applicable local requirements before entry and ensure that compliant fuel is available onboard, with sufficient time allowed for fuel changeover.

Scrubber Use

MARPOL allows for equivalent measures in the SOx regulations which means vessels can use exhaust gas cleaning systems (scrubbers) to meet both the global and ECA sulphur caps. Scrubbers remove sulphur from exhaust gases, with wash water as a byproduct, allowing the use of higher-sulphur fuels when operated and maintained according to IMO guidelines in MEPC.340(77).

Scrubbers are available as open-loop (discharging wash water directly into the sea), closed-loop (treating and recirculating the wash water) or hybrid systems. Local regulations vary by country, so members should consult specific guidelines on open or closed-loop usage; our resource here can be used as a guide.

New ECAs

The coverage of ECAs continues to expand, with MEPC 84 adopting the largest ECA to date in the North-East Atlantic.

Mediterranean Sea ECA

Entering into force on 1 May 2025, the Mediterranean Sea is now designated as an ECA, with the 0.10% sulphur limit in effect. Further details can be found here.

The Canadian Arctic and the Norwegian Sea ECA

The amendments to MARPOL Annex VI that designated the Canadian Arctic and the Norwegian Sea as new ECAs entered in to force on 1 March 2026. Both the Canadian Arctic and the Norwegian Sea ECAs for SOx will take effect on 1 March 2027, one year after these amendments came into force.

North-East Atlantic Ocean ECA

At MEPC 84 in 2026, the IMO adopted the North-East Atlantic Ocean as a new Emission Control Area, now the largest ECA designated to date.

This ECA covers a wide area including the waters of Greenland, Iceland, the Faroe Islands, and the western coasts of the United Kingdom and Ireland, extending south to Spain and Portugal, and effectively linking existing ECAs across Europe with the Canadian Arctic region.

The amendments enter into force on 1 September 2027, with SOx limits of 0.10% applying from 1 September 2028. NOx requirements will apply to new ships constructed on or after 1 January 2027 when operating within the area.

With most European and North American waters now designated as ECAs, ship operators should ensure that fuel procurement, changeover procedures, and crew awareness remain aligned with evolving MARPOL requirements when trading in these regions.

Lloyd’s Register Fuel Oil Bunkering Analysis and Advisory Service (FOBAS) on Wednesday (24 June) published a bulletin to provide ship operators with an updated reminder of marine fuel oil sulphur regulations under various regulatory frameworks: 

MARPOL Annex VI

Ships operating inside or outside Emission Control Areas (ECA) for Sulphur Oxides (SOx) i.e., ECA-SOx, are

required to comply with specific sulphur limits in respect of the fuel oils as used unless the particular

combustion systems (engine, boiler, other) in use have in operation an approved exhaust gas cleaning system as per MARPOL Annex VI regulation 4. These fuel oil limits are as follows;

  • Inside ECA-SOx: Max sulphur content of 0.10% m/m
  • Outside ECA-SOx: Max sulphur content of 0.50% m/m

MARPOL Annex VI regulation 14.3 currently gives the following as ECA-SOx together with the respective geographic limits:

  • Baltic Sea;
  • North Sea;
  • North American (which includes an area around the Hawaiian Islands);
  • US Caribbean Sea;
  • Mediterranean Sea;
  • Canadian Arctic; and
  • Norwegian Sea

Additionally, MEPC 84 adopted the North-East Atlantic as an ECA-SOx which will come into effect from 1 September 2028.

European initiatives

For EU, UK, and Turkish ports situated outside ECA-SOx, ships must switchover to a fuel with a maximum sulphur content of 0.10% m/m when at berth. Similarly, Norway and Iceland have also 0.10% m/m requirements for ships at berth and operating in Fjords (territorial / internal waters).

Other initiatives

Due to increasing concerns around the environmental impact from shipping on local air quality, there are a number of national and local regulations which require the use of low sulphur fuel oils, typically maximum sulphur content 0.10% m/m, or other measures by all or certain ships within defined areas. Examples of these are China, California (CARB), South Korea and Sydney. Furthermore, there can be other related restrictions, for example, on the discharges to sea from exhaust gas cleaning systems.

However, whereas with the MARPOL Annex VI ECA-SOx, there is a single point of reference as to which areas are covered, there is no such central registry for these regional, national or local initiatives taken outside MARPOL Annex VI. Consequently, in all the cases, it is important for ships to check with the relevant authorities beforehand in order to confirm the current status as regards SOx and related emission requirements in order to avoid any penalties – which can be substantial.
