mandatory permits, customs controls, and Portuguese naval enforcement, allowing Portugal to regulate and tax maritime trade.\u00a0<\/span><\/p>\r\n<ul>\r\n\t<li style=\"font-weight: 400\"><b>Mandatory Pass:<\/b><span style=\"font-weight: 400\"> Ships engaged in maritime trade had to obtain a Cartaz (pass) from Portuguese authorities.<\/span><\/li>\r\n\t<li style=\"font-weight: 400\"><b>Information

changed the functioning of Indian Ocean trade by bringing merchant shipping under Portuguese regulation, <a href=\"https:\/\/vajiramandravi.com\/current-affairs\/taxation-system-in-india\/\"
