Where a sending designated operator requires the services of one or more intermediate designated operators to forward postal items to the destination country, either in closed mails or as open (à découvert) transit mail, the sending operator pays transit charges to the intermediate (third-party) operator(s). These charges provide remuneration for the services rendered in respect of land, sea transit and air transit. The same principle applies to missent items and misrouted mails.
This contains information provided by designated operators on transit charges and groups of countries of destination for items received in transit à découvert.
A calculation tool has been developed to assist designated operators with the calculation of the weighted average charges for items forwarded in transit à découvert in order to update the Transit Compendium.
