Customs clearance inefficiencies impose significant costs on cross-border trade, particularly in landlocked economies such as Ethiopia where procedural bottlenecks persistently constrain trade competitiveness. This study examined the effects of customs clearance procedures on trade facilitation Performance at the Adama Customs Commission Branch, focusing on transit procedures, document declaration procedures, warehouse procedures, and digital system utilization. A quantitative approach with both explanatory and descriptive research designs was employed. Primary data were collected through structured questionnaires administered to 177 respondents from a target population of 318 employees. The population was stratified into five functional departments, and simple random sampling was applied within each stratum. Descriptive statistics summarized demographic characteristics and captured respondent perceptions through mean and standard deviation scores. Multiple linear regression was conducted as the main inferential technique after verifying the required diagnostic assumptions. The findings revealed that all four predictor variables have a statistically significant positive effect on trade facilitation Performance, jointly explaining a substantial proportion of its variance. Digital system utilization emerged as the strongest predictor, followed by document declaration procedures, transit procedures, and warehouse procedures. Accordingly, all hypotheses were supported. The study concludes that trade facilitation performance is not determined by isolated procedural improvements but rather by coordinated enhancement across all key procedural dimensions. The study recommends that the Ethiopian Customs Commission strengthen digital transformation, streamline declaration procedures, improve transit management, and modernize warehouse operations to reduce clearance delays and enhance trade competitiveness.
