customs purposes: the Customs Code (Council Regulation (EEC) No 2913/92) in particular  its Articles 22 to 246 thereof, and the Code's implementing provisions (Commission  Regulation (EEC) No 2454/93.  Tenderers must provide an undertaking signed by their representative certifying compliance  with this requirement. The tenderer is obliged to verify that the provided information is  correct. Otherwise, the tenderer risks to be excluded because of negligently misrepresenting  information. For more details, see Section 2.3.5. of the practical guide.  4.2  When submitting tenders, tenderers must state expressly that all the goods meet the  requirements concerning origin and must state the countries of origin. They may be asked to  provide additional information in this connection.  7.2  Each lot will form a separate contract and the quantities indicated for different lots will be  indivisible. The tenderer must offer the whole of the quantity or quantities indicated for each  lot. Under no circumstances must tenders be considered for part of the quantities required. If  the tenderer is awarded more than one lot, a single contract may be concluded covering all  those lots.  7.1  The tenderer may submit a tender for one lot, several or all of the lots. 7.3  A tenderer may include in its tender the overall discount it would grant in the event of some  or all of the lots for which it has submitted a tender being awarded. The discount should be  clearly indicated for each lot in such a way that it can be announced during the public tender  opening session.  7.4  Contracts will be awarded lot by lot, but the contracting authority may select the most  favourable overall solution after taking account of any discounts offered.  8.1  Tenderers will be bound by their tenders for a period of 90 days from the deadline for the  submission of tenders.  8.2  In exceptional cases and prior to the expiry of the original tender validity period, the  contracting authority may ask tenderers in writing to extend this period by 40 days. Such  requests and the responses to them must be made in writing. Tenderers that agree to do so  will not be permitted to modify their tenders and they are bound to extend the validity of  their tender guarantees for the revised period of validity of the tender. If they refuse, without  forfeiture of their tender guarantees, their participation in the tender procedure will be  terminated. In case the contracting authority is required to obtain the recommendation of the  panel referred to in Section 2.6.10.1.1. of the practical guide, the contracting authority may,  before the validity period expires, request an extension of the validity of the tenders up to the  adoption of that recommendation.
