Main articles
Some important articles are:

Kerosene tax
Article 24 of the Chicago Convention stipulates that when flying from one contracting state to another, the kerosene that is already on board aircraft may not be taxed by the state where the aircraft lands, nor by a state through whose airspace the aircraft has flown. This was intended prevent double taxation. However, there is no tax regulation in the Chicago Convention to refuelling the aircraft before departure.
The Chicago Convention does not preclude a kerosene tax on domestic flights and on refueling before international flights. Although the ICAO has produced various policy documents suggesting that no taxes of any kind should be placed on aviation fuel, none of these are legally binding, and they are not found in the Chicago Convention itself.
Although there are numerous bilateral agreements, so-called 'air services agreements', which make more extensive agreements, including often tax exemption when refueling an aircraft that has come from another contracting state, these are independent from the Chicago Convention; moreover, some air services agreements do allow for the taxation of fuels.
