Import of Petroleum Substances into (and trading in) the European Economic Area (EEA)

To facilitate the identification of imported Petroleum Substances, Concawe member companies have developed a “Shortlist” of Chemical Abstract Service Registry Numbers (CAS RNs) for Petroleum Substances that are commonly imported into the European Economic Area (EEA).

A total of 50 Shortlist CAS numbers have been identified covering all of the major classes of Petroleum Substances, e.g. straight run kerosines, light cat-cracked naphthas, heavy cat-cracked naphthas, white mineral oils, etc. Since the list has been developed only for commonly traded petroleum products, it is possible that an importer will not be able to assign a CAS RN from the Shortlist to all imports. It is the registrant’s responsibility to ensure that any chosen Shortlist number is an appropriate descriptor for the cargo that is being imported.

The Shortlist provides further details and is composed as follows:


  1. Tab marked “Shortlist”
    Provides details of the 50 Shortlist CAS numbers nominated, together with their full official definitions.
  2. Tab marked “Lookup list”
    Gives a full listing of petroleum product CAS numbers, grouped by the main classes:


    • Column A: simple code which defines whether, for the particular CAS RN, a Shortlist CAS RN has been identified that might describe the cargo:
      • code “✓” if a Shortlist number has been identified;
      • code “X” if none could be identified;
      • code “S” if the particular CAS RN is a Shortlist number itself.
    • Columns B – G: CAS RNs and their official definitions.
    • Column H: proposal for Shortlist number (where one has been defined) that might be considered to describe the cargo.
