The Post Office will continue processing the underpaid mails and inform the addressee. The arrangement is as below –
From 19 April 2016, Hongkong Post will cease to provide door delivery for underpaid mail items. The addressee will receive a notification card for paying the surcharge and collecting the mail at the designated post office (excluding mobile post offices).
To avoid mail delay, make sure that all mail items bear correct addresses of the recipients and sufficient postage by weight and mail format.
All underpaid items will be forwarded by surface route without prior notification. If the prepaid postage is insufficient to cover the transmission by surface route, the underpaid item will be charged on delivery with the amount of the deficiency, plus an additional fee charged by the country of destination.
