Kenya has strict customs regulations to protect its agriculture and security. Prohibited items include plastic bags (Kenya has a world-leading ban on single-use plastics), drones (unless specifically permitted by the Kenya Civil Aviation Authority), and pornographic material. Agricultural products like seeds, plants, and fruit are restricted to prevent the spread of pests. Additionally, it is illegal to import or export ivory, animal skins, or any other trophies made from endangered species. Firearms, ammunition, and explosives are strictly controlled and require specialized permits. Travelers should also be aware that the importation of "obscene" literature or counterfeit currency is a criminal offense. Even used clothing intended for resale (known locally as mitumba) is restricted for commercial importers, though personal luggage is usually exempt.
