The technical specifications, terms of reference, or technical reports shall be objective and accurate, or alternatively they can be formulated by the entity of contracting and approved by the user. Such technical specifications, terms of reference or technical reports shall provide access to the procurement process under equal terms and are not aimed to create barriers or affect the competition within the bidding process. Except for the exceptions established in the Regulations, the requirement does not make reference to any manufacturing process, or to any specific procedure characterizing such goods or services offered by a specific supplier/provider, or its trademarks, licenses or types, or to any origin or specific manufacturing process in order to sponsor or reject specific suppliers or products.

The bidders are not allowed to change the specifications or submit their own standard terms of business. The public entity publishes the tendered documents and then the bidders can formulate consultations and observations, which shall be answered by the entity. The entity shall publish a comprehensive report which answers these questions.

As a general rule, to act as a participant, bidder, contractor and/or subcontractor of the Government it is required to be registered with the Suppliers/Providers National Registry (RNP). However, the provisions which govern the Suppliers/Providers National Registry (RNP for its acronym in Spanish) and are regulated by the LCE are not applicable to micro-and small businesses (MYPES) duly registered with the National Micro-and-Small Business Registry (REMYPE)
