The study assessed the customs valuation system applied in Ethiopia and investigated thernexisting problems in the system. The methods adopted in the study include documentaryrnanalysis, in-depth interview and self administered questionnaires. The results suggestedrnthat the Customs Valuation System in Ethiopia does not provide fair, neutral and uniformrnvaluation and does not effectively protect traders from risk of arbitrary valuation by therncustoms officers. There is also risk of revenue loss to the government due tornunderinvoicing of imports by the traders since controlling mechanisms such as PostrnClearance Audit (PCA) are not adequately developed. Therefore, the Government ofrnEthiopia needs to strengthen the controlling mechanisms within the customs valuationrnsystem since duties and taxes on foreign trade contribute the significant portion of its taxrnand duty revenues
