"Railway Fast Clearance" is a facilitation measure jointly launched by customs and railway authorities to promote the development of high-quality "Belt and Road" Initiative (BRI) and international railway intermodal transport services. After corporate clients complete the "Railway Fast Clearance" procedures in Tianjin, they no longer need to go through local customs procedures when goods arrive at the Erenhot Railway Port. They only need to complete the railway transshipment operation to export without additional customs clearance, thereby reducing the port clearance time by 1 to 2 days compared to previous procedures.
