62 STAT.] MULTILATERAL-UNIVERSAL POSTAL UNION-JULY 5, 1947 2. Articles which are not prepaid, or which are insufficiently pre- paid for the first part of their journey, are marked with the charge which would have been applied to them if they had been addressed directly from the point of origin to the place of new destination. 3. Articles regularly prepaid for the first part of their journey and on which the additional charge for their subsequent transmission has not been paid before their redirection are marked with a charge equal to the difference between the amount of postage already paid and that which would have been collected if the articles had originally been sent to their new destination. 4. Articles originally addressed to the interior of a country and duly prepaid in accordance with the domestic rates are considered as articles regularly prepaid for their first transmission. 5. Articles originally sent free of postage in the domestic service of a country are marked with the charge to which they would have been liable if they had been addressed directly from the point of origin to the place of new destination. 6. At the time of forwarding, the redispatching office applies its date stamp on the front in the case of articles in the form of cards, and on the back for all other classes of mail. 7. Ordinary or registered articles which are returned to the senders for completion or correction of the address are not considered as redi- rected correspondence when returned to the service; they are treated as new correspondence, and are therefore liable to new postage charges. 8. The customs duties and other non-postal charges whose cancela- tion it has been impossible to obtain upon redirection or return to origin (Article 138 hereafter) are recovered, through the C. O . D . service, from the Administration of new destination. In that case, the Ad- ministration of original destination attaches to the article an explana- tory note and a C. O. D . money order (Form R 3 of the Agreement concerning collect-on -delivery articles). If the C. O . D . service is not in operation between the Administrations concerned, the charges in question are recovered through correspondence. 9.
