Judging from the relevant information, the porcelain taken out of the country does not look at the age, nor does it look at whether the country prohibits the export. The state has clear legal provisions in this regard, and it can only be exported if it leaves the country in large quantities. The commodity is in the catalogue of entry-exit commodities subject to inspection and quarantine by entry-exit inspection and quarantine institutions. Therefore, inspection and quarantine institutions implement compulsory inspection and quarantine. In addition, you need to issue a certificate to export. If the place of origin is inconsistent with the place of declaration, you need to complete the quality inspection at the place of origin before you can declare. Without this customs clearance form, the customs will not accept customs declaration. For detailed information, it is best to consult the local official website for first-hand authoritative information.
