Customs valuation is the process of determining the official value of imported goods for customs purposes. Customs authorities use this value to calculate import duties, taxes, and certain fees. The customs value is often based on the transaction value, or the price paid or payable for the goods, with required adjustments such as assists, royalties, commissions, packing costs, or transport and insurance depending on local customs rules. Accurate valuation is essential for duty calculation, compliance, and avoiding penalties.
