Under this service a person who wishes to obtain a reply from an overseas client without putting him to the expense of paying postage may enclose in his communication an unstamped International Business Reply item in the form of an envelope or a card of a prescribed design. The client can post the International Business Reply item by airmail service in the ordinary way, but without stamp; and the addressee will pay the charges for all the replies he receives.

In the reverse direction, a member of the public may post an International Business Reply item originating from abroad back to the sender by airmail service without stamp if Hongkong Post provides International Business Reply service to the country concerned.
