    Three main resources and reserves classifications, internationally recognized are: United Nations Framework Classification of Resources/Reserves (UNFC), CRIRSCO for solid mineral commodities and PRMS for hydrocarbons. The most universal is UNFC formulated within UN Economic Commission of Europe. It allows comparison of varied used national and institutional classifications and present resources data in uniform manner. Its application is recommended by UN Economic and Social Commission (ECOSOC resolution 2004/233). In the UNFC resources are classified on the basis of three criteria: economic and social viability (E), feasibility status (F) and geological assurance (G). Each of them is categorized using numerical coding system. The combinations of particular categories form classes of resources designed by three digit symbol representing EFG categories respectively. Polish classification is based on similar rules as UNFC, CRIRSCO and PRMS and with some assumptions respective classes of UNFC can be found. The substantial difference is the mode of presentation of resources and reserves data: hierarchical in the Polish classification and complementary in UNFC (as well CRIRSCO and PRMS). In Polish resources inventory, according to international rules should be presented separately: industrial, not industrial resources and supposed economic (balance) resources not subdivided to industrial and not industrial.
