The international waterway of the Sava River and its navigable tributaries is defined by the Protocol on Navigation Regime to the Framework Agreement on the Sava River Basin, as follows: for the Sava River from rkm 0 (Beograd) to rkm 594 (Sisak), Kolubara River from rkm 0 to rkm 5, Drina River from rkm 0 to rkm 15, Bosna River from rkm 0 to rkm 5.00, Vrbas River from rkm 0 to rkm 3, Una River from rkm 0 to rkm 15, and on the Kupa from rkm 0 to rkm 5.

The Sava River waterway is classified in accordance with Decisions 19/08, 14/12 and 5/17 on the classification of the Sava River waterway as follows:

The waterway is marked for navigation in accordance wth the current conditions on the waterway, and the marking system is prone to changes according to such conditions and river engineering works on waterway. The current state of the marking system can be found here.
 
The beginnings of commercial navigation on the Sava date back to the Roman Empire, and with the more serious navigation and regulation of the waterway began in the first half of the 19th century, when in 1834 the steamer "Sophia" (60 hp and 300 t carrying capacity) sailed into the Sava with the with the task of examining navigation conditions. As early as 1844 a regular shipping line was established between Sisak and Zemun. The development of navigation continued after World War II culminating in the 1980s of the 20th century.

Due to the events related to the dissolution of the Socialist Federal Republic of Yugoslavia in the 1990s, there was complete interruption of navigation and any significant maintenance of the waterway, which resulted in significant deterioration of the waterway dimensions, particularly depths which are limiting factor for any commercial navigation.
In order to rederess such a situation, the Sava Commission  together with the Member States, undertook a a wide range of activities, the most important being the development of the Pre-Feasibility Study for Rehabilitation and Development of the Sava River Waterway (here) and the Feasibility Study and Project Documentation for the Rehabilitation and Development of Transport and Navigation on the Sava River Waterway (here).
The Sava Commission  and the Sava River Basin countries continue to undertake measures, striving for the restoration and development of the waterway by upgrading the Sava River waterway between Belgrade and Sisak, to at least waterway class IV and to class Va on the sectors where feasible. The incresed navigability upstream of Sisak is planned for later stage in line with the development of economic activities and transport.
The restoration and development of waterways and navigable infrastructure in general, would significantly contribute to the competitiveness of the transport services market, which is in line with all strategic documents of the transport policy of the states parties to the Framework Agreement on Sava River.
