Doing Business records the time and cost associated with the logistical process of exporting and importing goods. Doing Business measures the time and cost (excluding tariffs) associated with three sets of procedures—documentary compliance, border compliance and domestic transport—within the overall process of exporting or importing a shipment of goods. The most recent round of data collection for the project was completed in May 2018. See the methodology for more information. Given the importance of education and communication for trade professionals, in Doing Business 2019 the trading across borders questionnaire included research questions on education requirements, training opportunities and reform communication for customs officials and customs brokers. These data are not used to compute the trading across borders score or ranking.
