Annual Fees


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.
