UIS Annual Fees


The UIS General Assembly at the 17th International Congress of Speleology (Sydney, Australia, 2017), approved the amended of fee categories of member countries, which will be considered according to the number of speleologists in the national organization or organizations that represent the country to the UIS. The new annual contributions will be as follows, starting after the 17th ICS, Sydney, Australia: 


The annual contribution to UIS is one of the following:

  • Category A (2000 speleologists or more): 480 EUR
  • Category B (at least 1000 speleologists but fewer than 2000): 360 EUR
  • Category C  (at least 100 speleologists but fewer than 1000): 240 EUR
  • Category D  (less than 100): 60 EUR



Each UIS member country has the free choice of which category, in accordance with their relative financial position and the number of speleologists or speleological societies/ associations/ federations/ clubs/ institutions in their country.

The UIS Bureau is authorized to reduce or waive the contribution if the UIS member-country makes a written request. If the UIS Bureau requires, the UIS member country has to give reasons for the difficulties of a payment.

This authorization by the UIS Bureau to reduce or waive a contribution ensures that the inability to pay caused by actual political problems or difficulties will not be an argument to exclude any member country from international collaboration within the structure of the UIS.
