Reported ad-valorem range: 0%–6.5%.
Reported historical ad-valorem MFN simple average for 2023, not a national tariff schedule. No preferential rates, additional duties, VAT, excise or import permissions are determined.
Not a current 2026 national duty. The HS6 average does not determine the duty of a particular national subdivision, origin or shipment.

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.
