Fuel Regulations

China: Diesel Fuel

The national sulfur implementation schedule for fuels in China is summarized in Table 1. Low sulfur diesel fuel (S ≤ 500 ppm) became available “nationwide” in 2004 but 0.2% sulfur fuel was commonly supplied after this date. Some cities and regions can require fuels with sulfur levels lower than the national standard.

Onroad DieselChina I (China II available)China IIIChina IVChina V
Nonroad DieselChina IChina IIICh IVChina V
Note: Sulfur limits for China I, II, III, IV and V diesel are 2000, 500, 350, 50 and 10 ppm (m/m), respectively. Sulfur limits for China II, III, IV and V gasoline are 500, 150, 50 and 10 ppm (m/m), respectively.

Regulation GB 17691-2005 [2881] specified emission limits for China III-V stages, but included fuel specifications for the China III stage only. Faced with the lack of official fuel standards to ensure availability of ultra low sulfur fuels that were necessary to enable emission technologies at the China IV/V stages, the Ministry of Environmental Protection adopted regulation GWKB 1.2-2011 which regulated sulfur and polyaromatics as toxics. Selected specifications and availability status are shown in Table 2.

There are two national diesel fuel standards in China, GB 19147 for onroad vehicles and GB 252 (general diesel fuel) for other applications including nonroad engines:

  • Onroad Diesel Fuel—For onroad applications, GB 19147-2009 was implemented in stages throughout the country starting in January 2010. GB 19147-2013 for China IV fuel was published in February 2013.

    In 2008, the maximum fuel sulfur limit in several cities was set at 50 ppm (e.g., DB11/239-2007). In 2012, the maximum sulfur limit in Beijing was set at 10 ppm (DB11/239-2012).

    In February 2013, the State Council issued a timetable for its program to upgrade fuel quality nationwide. By the end of 2014, automotive diesel fuel sulfur will be set at 50 ppm (China IV or National IV) and by the end of 2017, sulfur limits for automotive gasoline and automotive diesel will be 10 ppm maximum (China V or National V). Diesel fuel standards for China V were required to be issued by July 2013. In April 2015, the State Council advanced timeline for 10 ppm gasoline and diesel fuel by one year making it available nationwide by January 2017.

  • General Diesel Fuel—For other applications such as trailers, locomotives with internal combustion engines, construction machinery, vessels, generator sets, 3-wheelers and low-speed trucks, national fuel standard GB 252 is available. GB 252-2000 set the sulfur level at 0.2%. GB 252-2011 set July 1, 2013 as the transition date from a sulfur limit of 0.2% to a limit of 0.035%. In April 2015, the State Council set the limit to 50 ppm starting In July 1, 2017, and 10 ppm starting January 1, 2018.

There are also several municipal and provincial diesel fuel standards.
