Stockholm, Dear Sir/Madam, Tenders must be submitted exclusively via the electronic submission system (e ‐ Submission) available from the above website 2 $^{ }$and  accessible on the Funding and Tenders Opportunities portal (F&T portal)$^{3}$. Tenders submitted in any other way (e.g. e ‐ mail or by letter) will be disregarded. In order to submit a tender using e ‐ Submission, economic operators (each member of the group in the case of a joint tender) will need to register in the European Commission's Participant Register (http://ec.europa.eu/research/participants/portal/desktop/en/home.html) ‐  an online register of organisations participating in EU calls for tenders or proposals. On registering each organisation obtains a Participant Identification Code (PIC, 9 ‐ digit number) which acts as its unique identifier in the above register. Instructions on how to create a PIC can be found on this page: https://webgate.ec.europa.eu/fpfis/wikis/pages/viewpage.action?pageId=308979301. Economic operators already registered in the Participant Register shall reuse their existing PICs when preparing tenders in e ‐ Submission. IMPORTANT: In case of discrepancy between the total reference price indicated in the financial tender in annex II and the price encoded in the e ‐ Submission application, the price mentioned in annex II shall prevail. 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. IMPORTANT: In case of any problems with the submission of your electronic tender, you must contact the Support team in reasonable time before the time limit for receipt (see Quick Guide for Economic Operators: https://webgate.ec.europa.eu/digit/opsys/esubmission/assets/documents/manual/quickGuide_en.pdf). Economic operators interested in this contract are invited to submit a tender in one of the official languages of the European Union. ECDC is planning to award the contract(s) resulting from the above procurement procedure. The procurement documents consist in the contract notice, this invitation letter, the draft contract(s) and the tender specifications with their respective annexes. All documents are available at the TED e ‐ Tendering website$^{1}$ (see specific link in the contract notice): https://e ‐ Tendering.ted.europa.eu 1. Submission of tenders $^{1}$ Subscription to the call for tender at the above link allows interested economic operators to receive e ‐ mail notifications when new information or documents are published. Subscription is free of charge and does not involve any commitment to submit a tender. $^{2}$ For detailed instructions on how to submit a tender please consult the e ‐ Submission Quick Guide available at: https://webgate.ec.europa.eu/digit/opsys/esubmission/assets/documents/manual/quickGuide_en.pdf. The supported browsers, file types, size of attachments and other system requirements can be consulted at: https://webgate.ec.europa.eu/fpfis/wikis/x/f6dqEg. In case of technical problems, please contact the e ‐ Submission Helpdesk (see contact details in the e ‐ Submission Quick Guide) as soon as possible. $^{3}$ https://ec.europa.eu/info/funding ‐ tenders/opportunities/portal/screen/home Page  1  of  4 Subject: Scientific support to data analysis and coordination activities of the European Surveillance of Antimicrobial Consumption Network (ESAC ‐ Net) Ref.: OJ/2021/DPR/23669
