The Customs department has allowed self-sealing procedure from October 1 for containers to be exported, as it aims to move towards a 'trust based compliance environment' and trade facilitation for exporters.In a circular to all Principal Chief Commissioners, the Central Board of Excise and Customs (CBEC) said exporters who were availing facility of sealing at the factory premises under the supervision of customs authorities will be automatically entitled for self-sealing facility. It said that permission once granted for self-sealing at an approved premise will remain valid unless withdrawn. However, in case of change in the premise, a fresh approval from Customs department will be required.
