The price for the tender must be quoted in euro. Tenderers from countries outside the euro zone  have to quote their prices in euro. The price quoted may not be revised in line with exchange  rate movements. It is for the tenderer to bear the risks or the benefits deriving from any  variation. Prices must be quoted free of all duties, taxes and other charges, including VAT, as the European  Union is exempt from such charges under Articles 3 and 4 of the Protocol on the privileges and  immunities of the European Union. The amount of VAT may be shown separately. The quoted price must be a fixed amount which includes all charges (including travel and  subsistence). Travel and subsistence expenses are not refundable separately.  Tenders must be submitted through the electronic submission system (see point 1 in the Invitation to  tender for further information). Make sure you submit your tender on time:  you are advised to start completing your tender early. To  avoid any complications with regard to late receipt/non receipt of tenders within the deadline, please  ensure that you submit your tender several hours before the deadline. A tender received after the deadline  indicated in the procurement documents will be rejected. 1.7 Identification of the tenderer  The tender must include a  cover letter  signed by an authorised representative presenting the name of the  tenderer (including all entities in case of joint tender) and identified subcontractors if applicable, and the  name of the single contact point (leader) in relation to this procedure. In case of joint tender, the cover letter must be signed either by an authorised representative for each  member, or by the leader authorised by the other members with powers of attorney. The signed powers  of attorney must be included in the tender as well. Subcontractors that are identified in the tender must  provide a letter of intent signed by an authorised representative stating their willingness to provide the  services presented in the tender and in line with the present tender specifications. All tenderers (including all members of the group in case of joint tender) must provide a signed Legal Entity  Form with its supporting evidence. The form is available on:  http://ec.europa.eu/budget/contracts_grants/info_contracts/legal_entities/legal_entities_en.cfm Tenderers that are already registered in ECDC’s accounting system (i.e. they have already been direct  contractors) must provide the form but are not obliged to provide the supporting evidence.  The tenderer (or the leader in case of joint tender) must provide a Financial Identification Form with its  supporting documents. Only one form per tender should be submitted. No form is needed for  subcontractors and other members of the group in case of joint tender. The form is available on:  http://ec.europa.eu/budget/contracts_grants/info_contracts/index_en.cfm The tenderer (and each member of the group in case of joint tender) must declare whether it is a Small or  Medium Size Enterprise in accordance with Commission Recommendation 2003/361/EC. This information  is used for statistical purposes only.  1.8 Language  Tenders must be submitted in one of the official languages of the European Union. ECDC prefers, however,  to receive documentation in English. Nonetheless, the choice of language will be not play any role in the  consideration of the tender.  6
