From the ship's own AIS transponder (static data, message 5). The crew sets the type code; codes 70-79 mean cargo ship, 80-89 tanker (ITU-R M.1371 Table 53).

Questions
Can the category change?
Rarely: only when the crew changes the AIS type code or the ship joins or leaves a carrier's schedule. The list is rebuilt from the AIS registry and the schedules on each data update.
How do I see where a ship is now?
Open the ship in Navo vessel tracking (the Track link in each row). It shows the latest AIS position, speed, course and the destination typed by the crew.
