Action 1 - Inter Laboratory Inventory of Analytical Determination

ILIADe, Inter Laboratory Inventory of Analytical Determination

ILIADe is a database of analytical methods, initially developed as a shared directory by the Italian Customs Agency and currently hosted by the European Commission. Its main purpose is to improve the effectiveness of customs laboratories, by providing them with an easily accessible and up-to-date compilation of analytical methods that they are required to use for customs and excise purposes, as well as for authenticity and quality controls, consumer health protection and environmental controls.

The database contains official analytical methods, international standards and in-house developed methods. Its content is discussed and validated by a project group.

Access the public database.

The full ILIADe database is accessible to Member States’ customs laboratories. Methods and contacts are also available to third countries upon special request sent to the mailbox TAXUD-DDS-ECICSatec [dot] europa [dot] eu.

CLEN Methods

Customs laboratories cooperate to develop in-house CLEN methods with the aim of providing a harmonised approach to analysis and classification issues.

A CLEN method is an analytical procedure established and used by laboratories for customs and excises purposes when no other official method is available or when a method with known performance is required.

The scope of the method, its description and its performance characteristics are first defined with the framework of the CLEN Actions. The method is then adopted by the CLEN during a Plenary Meeting.

The six CLEN Actions are linked to one another: for instance, Action 2 activities (Inter-comparisons and method validations studies) often result in validated methods that will be included in the ILIADe database.

The available CLEN methods are displayed below (click on the link to download the methods):
