Application Assessment

Upon receipt of the application, EPD or the organization(s) authorized by EPD will check if the applicant submits all necessary information. EPD or the organization(s) authorized by EPD may request the applicant to provide supplementary information or make clarification as necessary. Based on the information provided by the applicant, EPD or the organization(s) authorized by EPD may request the applicant to arrange a site visit for staff from EPD or the organization(s) authorized by EPD to observe the applicant's actual operations. The objective is to assess whether the applicant fulfills registration requirements and has adequate capability to handle WCO properly.

The time for application assessment depends on whether the applicant can supply all the required information and documents and cooperate with EPD or the organization(s) authorized by EPD in the on-site assessments. In general, application results will be announced in batches within 1-2 months after the site assessment has been completed. EPD will issue a registration certificate with registration number to each successful applicant. Besides, successful applicant's information (remarks: information marked with * in the application form) will be uploaded to Registration Lists at EPD's website. EPD will also inform unsuccessful applicants of the outcome with justification(s) by letters.


Good Practice Guide

To facilitate WCO processors to comply with the registration requirements, EPD publishes “Good Practice Guide for Registered WCO Processors” (Chinese version only). The Guide provides guidelines on WCO processing, record keeping and etc. Processors should ensure their operations are in compliance with the registration requirements stated in the Guide, otherwise EPD will take necessary follow up actions (e.g. revoking their registrations etc.).

Registration will be valid for 2 years. If registered parties wish to maintain their registrations, they should submit an application for registration renewal at least 2 months before the end of valid period of their registrations (application form can be downloaded and submitted here).
