In the process of undertaking the baseline study of Trade and Transport Facilitation Monitoring Mechanism (TTFMM) in Bhutan, six studies are carried out to provide multiple facets of trade and transport facilitation covering export and import of specific products, corridors and border crossings. A synthesis report is also produced based on five study reports. The current report is focused on the Time Release Study (TRS) at Phuentsholing Land Border Customs Station under the Regional Revenue and Customs Office, Phuentsholing, Bhutan. It is a stand-alone document itself and in the meantime the 5th report of a series of 6 studies on TTFMM in Bhutan. It feeds the TTFMM synthesis report.
