Facilitation: Customs, Immigration and Health Requirements
This domain tests Annex 9 and the Convention Articles on the movement of aircraft, people and goods across borders. Questions ask which formality may be required, which charge may be levied, and which document is needed for a transit stop.
Facilitation principles
Annex 9 implements Articles 10, 13, 22, 24 and 35 of the Convention. Article 22 obliges States to adopt measures to facilitate and expedite navigation by aircraft and to prevent unnecessary delays. Article 10 requires landing at a designated customs airport unless specially authorised. Article 13 allows a State to apply its laws on entry, clearance, immigration, passports, customs and quarantine. Article 16 permits search of aircraft on landing and departure but without unreasonable delay.
Charges and customs
Article 15 restricts airport and similar charges to the cost of the facilities and services provided, and they must be published. No charge may be made merely for the transit, arrival or departure of an aircraft, or for the carriage of fuel, oil, spare parts and stores retained on board. Article 24 exempts fuel, lubricating oils, spare parts, regular equipment and aircraft stores retained on board from customs duty; the exemption ends if the goods are unloaded. Article 35 permits a State to restrict or prohibit the carriage of munitions of war over its territory.
Documents
Annex 9 prescribes the General Declaration, passenger manifest and cargo manifest, and encourages elimination of unnecessary documents. Disinsection requirements must follow WHO guidance. Health requirements are governed by the WHO International Health Regulations; a yellow fever vaccination certificate may be required for travellers arriving from an infected area, and States must not impose requirements more restrictive than the Regulations.
Worked example
A flight lands only to refuel, with passengers remaining on board or in the transit area. A General Declaration is provided, but no customs duty is due on fuel remaining in the tanks and no immigration processing is required for passengers who do not enter the State. If passengers disembark into the national territory, the full entry, immigration and customs formalities of Article 13 apply.
Traps
Fuel retained on board is exempt; fuel unloaded and delivered is not. Article 15 charges are cost-related, not profit-making. Annex 9 does not override national immigration law. Disinsection and vaccination requirements follow WHO guidance, not operator preference.
