Under Honduras’ Financial Balance and Social Protection Act, imports of motor vehicles over ten years old, except classic collectible cars, and passenger buses over thirteen years old are prohibited. Imports of refurbished and right-hand drive vehicles are also prohibited. Import restrictions are also imposed on unlicensed firearms and ammunition, toxic waste and chemicals, pornographic material, and narcotics. Spearfishing is illegal and scuba divers may therefore not enter the country with spear guns. Plants may be brought in with appropriate phytosanitary certificates. Import restrictions are based on Phyto-sanitary, public health, and national security factors.
