Please submit accurate electronic customs declaration for the customs assessment.

Senders are required to provide a local mobile phone number that can receive SMS, so that if necessary they can receive messages issued by Hongkong Post on the requests by overseas customs authorities related to customs clearance of the mail items and take follow up actions. Hongkong Post will not embed hyperlinks in the related SMS requesting for any personal information. Members of the public could contact Hongkong Post enquiry hotline 2921 2222 direct if they have any doubts on the SMS received. For details, please click here.

Service FeaturesOpen/collapse

These may be sent to any address in the world for a postage rate of $3.7. As the economics of the aerogramme service are closely related to the weight of the aerogramme form itself, an aerogramme should not contain any enclosures or have an attachment other than a postage stamp or postal form / label used for posting. If an aerogramme has an enclosure or an attachment other than a postage stamp or postal form / label used for posting, or in any way fails to comply with the conditions laid down by the Postmaster General for the aerogramme service, it will be considered to be posted as an air mail item and postage rates corresponding to the mail format classification for Small Letter, Large Letter and Packet must be paid.

Plain stamped official aerogrammes are obtainable from any post office at $3.7 each. Privately manufactured aerogrammes may be used if they bear an indication that they have been approved by the Postmaster General. Forms which do not bear such an indication will be treated as ordinary air mail items and charged corresponding to the mail format classification for Small Letter, Large Letter and Packet. The postage on privately manufactured aerogrammes may be prepaid by means of a $3.7 postage stamp or, alternatively, by a franking impression made directly on the aerogramme form and not affixed by label.
