Agreement on Government Procurement
World Trade Organization
Article XIII: Submission, Receipt and Opening of Tenders and Awarding of Contracts

1. The submission, receipt and opening of tenders and awarding of contracts shall be consistent with the following:
   
   (a) tenders shall normally be submitted in writing directly or by mail. If tenders by telex, telegram or facsimile are permitted, the tender made thereby must include all the information necessary for the evaluation of the tender, in particular the definitive price proposed by the tenderer and a statement that the tenderer agrees to all the terms, conditions and provisions of the invitation to tender. The tender must be confirmed promptly by letter or by the despatch of a signed copy of the telex, telegram or facsimile. Tenders presented by telephone shall not be permitted. The content of the telex, telegram or facsimile shall prevail where there is a difference or conflict between that content and any documentation received after the time-limit; and
   
   (b) the opportunities that may be given to tenderers to correct unintentional errors of form between the opening of tenders and the awarding of the contract shall not be permitted to give rise to any discriminatory practice.
   
   Receipt of Tenders
   
   
2. A supplier shall not be penalized if a tender is received in the office designated in the tender documentation after the time specified because of delay due solely to mishandling on the part of the entity. Tenders may also be considered in other exceptional circumstances if the procedures of the entity concerned so provide.
   
   Opening of Tenders
   
   
3. All tenders solicited under open or selective procedures by entities shall be received and opened under procedures and conditions guaranteeing the regularity of the openings. The receipt and opening of tenders shall also be consistent with the national treatment and non-discrimination provisions of this Agreement. Information on the opening of tenders shall remain with the entity concerned at the disposal of the government authorities responsible for the entity in order that it may be used if required under the procedures of Articles XVIII, XIX, XX and XXII.
   
   Award of Contracts
   
   
4. (a) To be considered for award, a tender must, at the time of opening, conform to the essential requirements of the notices or tender documentation and be from a supplier which complies with the conditions for participation. If an entity has received a tender abnormally lower than other tenders submitted, it may enquire with the tenderer to ensure that it can comply with the conditions of participation and be capable of fulfilling the terms of the contract.
   
   (b) Unless in the public interest an entity decides not to issue the contract, the entity shall make the award to the tenderer who has been determined to be fully capable of undertaking the contract and whose tender, whether for domestic products or services, or products or services of other Parties, is either the lowest tender or the tender which in terms of the specific evaluation criteria set forth in the notices or tender documentation is determined to be the most advantageous.
   
   (c) Awards shall be made in accordance with the criteria and essential requirements specified in the tender documentation.
   
   Option Clauses
   
   
5. Option clauses shall not be used in a manner which circumvents the provisions of the Agreement.
