For import and export goods (including transit goods) listed in the Catalogue of Entry-exit Goods for Inspection and Quarantine by Entry-exit Inspection and Quarantine Authorities (the Catalogue), the Customs will examine and release the goods against the Import Goods Clearance Slip or Export Goods Clearance Slip issued by the entry-exit inspection and quarantine authorities at the place of customs declaration. Unless otherwise specified in AQSIQ documents, if an enterprise is required to provide inspection proofs on the quantity etc. of import and export goods not listed in the Catalogue, it may obtain such proofs from inspection organisations designated, recognised or approved by AQSIQ.
Inspection and quarantine procedures normally include six steps: application for inspection, calculation and collection of fees, sampling, inspection and quarantine, decontamination treatment (quarantine treatment), and issuance of certificate for release of goods.
