Items per kilogramme (IPK) study
Study on the number of items per kilogramme in the mail flows exchanged between the designated operators of Union member countries
The objective of the IPK study is to collect information in support of the work on the development of future proposals for the UPU remuneration system. The collected information will result in a better understanding of the worldwide average composition of mail, according to weight, format and content, for letter-post, parcel-post and EMS items. It will also support the establishment by the POC, as the Regulations require, of the recommended IPK values to be used in order to avoid sampling costs.
The sampling period will be the month of May 2018. For letter-post items, if continuous sampling is carried out, the results split by format for the second quarter of the year (1 April to 30 June 2018) may be provided instead.
The sampling forms are available in Excel format below.
The data will be handled in strict confidence by International Bureau staff who have signed confidentiality/non-disclosure agreements.
