As per the ISO 8217:2017, the present (as for Aug 2019) classification is as follows:
DM - Distillate Marine Fuels - applied to fuels: DMX, DMA, DFA, DMZ, DFZ, DMB, DFB. Grades differ mostly by the maximum permitted Kinematic viscosity and Cetane index. Grades DMB and DFB have slightly higher permitted Density and Sulfur content.
RM - Residual Marine Fuels - applied to fuels: RMA10, RMB30, RMD80, RME180, RMG180, RMG380, RMG500, RMG700, RMK380, RMK500, RMK700. Grades differ by the maximum: Kinematic viscosity, Density, CCAI, Carbon residue, Ash, Vanadium, Sodium, Aluminium plus silicon
Please note, that starting the year 2020, marine fuels with Sulfur content of more than 0.50% will be banned. Above classification does not reflect the Sulfur content.
