## 1.7 Structure and content of the tender 

All tenders must contain a financial tender to be submitted according to the form in section 4. Annexes . 

The tenderer's attention is drawn to the following points: 

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 refundable only for ad hoc consultancy services where daily rate is applied, and only if travel is requested by ECDC. 

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.
