Regulations Governing Customs Clearance for Goods in Logistics Centers Article 11

When exporting goods from logistics centers, the logistics center or the holder of the goods is required to file an application and declare it on-line to the Customs by the logistics center. Export is allowed only following completion of customs clearance. Once the goods are exported and duty offset or refund is desired, a certificate of export can be issued by the Customs upon which the process may begin.
