The Customs authorities should therefore be able to require documentary evidence of origin in cases other than those provided for in Standard 2. For such action to be justified, however, there must be suspicion of fraud. Recommended Practice 1. Contracting Parties which have aligned their forms of certificate of origin on the model form in Appendix I to this Annex should notify the Secretary General of the Council accordingly. The form in Appendix 1, which reproduces that appended to the Council Recommendation of 16 January 1973 is a lay-out key, i.e. it can be adapted to take account of particular requirements but certain entries must obligatorily appear at the prescribed places.
Reference is facilitated by the numbering of the boxes.
However, the numbering used in the standard form is not binding and each Contracting Party remains free to number the boxes according to its own needs, taking into account in particular the possibility offered of subdividing the boxes.
