Search the ZATCA integrated tariff at zatca.gov.sa in Arabic or English. Saudi Arabia uses 12-digit codes: the first 6 are international, the rest GCC/Saudi-specific. Classify by the product's essential character and material — chapter notes override intuition, and suppliers' 6-digit codes are not precise enough for duty.
The code sets your duty rate (0–25%) and certificate requirements. For recurring products, a binding ZATCA ruling fixes classification before shipping.
