Filing and registration is a procedural operation, not an examination and approval of whether foreign trade business can be operated. Enterprises planning to carry out import and export business should first go through the formalities for changing the business scope with the local administrative department for industry and commerce, increase the import and export business of goods or technologies or the corresponding business scope, and then go through the registration formalities with the commercial department. Individual industrial and commercial households (sole proprietors) also need to submit personal property (assets) certificates before they can register for the record. The applicant shall, within 30 days, go to the local customs, inspection and quarantine, foreign exchange, taxation and other departments to handle the relevant procedures required for foreign trade business with the registration form stamped with the seal of filing and registration. If you don't do it within the time limit, the application form will automatically become invalid, and only after these procedures are completed can you consider the procedures complete.
