Each destination shows its own source label. Oman uses its national schedule; Qatar and UAE entries may cite their separately published references and unresolved exceptions. Other entries retain the historical GCC reference. National codes, duty notes, restrictions and tax treatment can differ; verify with the destination customs authority.
