Brazil has established an obligation for passive infrastructure sharing to deliver telecom services to end users. In addition, passive infrastructure sharing is practised in the mobile sector and in the fixed sector. According to Art. 73 of Law No. 9.472/1997, telecom service providers of collective interest have the right to use posts, ducts, conduits, and easements owned or controlled by a provider of telecom services or other services of public interest in a non-discriminatory manner and at fair and reasonable prices and conditions. On the other hand, Law No. 13.116/2015 establishes general rules for the implementation and sharing of telecommunications infrastructure. Additionally, Resolution No. 683/2017 of the "Agência Nacional de Telecomunicações" (Anatel, National Telecommunications Agency) approved the Regulation for Sharing Support Infrastructure to the Provision of Telecommunications Services, which aims to discipline the sharing of infrastructure.

It is reported that the federal government of Brazil owns 96.3% of the shares in the telecommunications company Telecomunicações Brasileiras S.A. (Telebras). The federal government directly holds 92.43% of the total, the Financiadora de Estudos e Projetos (FINEP), an entity of the federal government, owns 3.74%, and Banco do Brasil S.A., a bank under federal governmental control, holds 0.11%

It is reported that Brazil mandates functional and accounting separation for operators with significant market power (SMP) in the telecom market.

It is reported that although Brazil permits Brazilian-owned entities to acquire the exclusive right to operate a satellite and its associated frequencies from specific positions, foreign-licensed satellite operators may obtain only a non-exclusive right (a landing right) to provide service in Brazilian territory. The National Telecommunications Agency (ANATEL) grants these landing rights for a fixed term of no longer than 15 years, after which the operator must reacquire the landing rights in order to continue providing services. Foreign operators are also required to pay higher annual landing fees than Brazilian firms.

Brazil has not appended the World Trade Organization (WTO) Telecom Reference Paper to its schedule of commitments.

Brazil is not a party to the World Trade Organization (WTO) Agreement on Government Procurement (GPA); however, it has held observer status since October 2017.

Art. 222 of the Brazilian Constitution stipulates that a minimum of 70% of the total voting capital of news companies must be held, either directly or indirectly, by native Brazilians or by individuals who have been naturalised Brazilians for over ten years. Furthermore, Art. 2 of Law No. 10.610/2002 also restricts foreign ownership to no more than 30% of the capital stock and voting capital of news companies. It should be noted that neither the Constitution nor the Law defines what constitutes a news company.

The Federal Constitution, in Art. 222, states that editorial responsibility and the activities regarding selection and management of the programming to be disseminated shall be carried out exclusively by native Brazilians or those naturalised for more than 10 years in any social communication medium. It also adds that electronic social communication media, regardless of the technology used to deliver the service, shall comply with the principles stipulated in Art. 221, as provided by specific legislation, shall also ensure priority to Brazilian professionals in producing Brazilian programs.
This is reiterated in Law 10.610/2002, which establishes that the control and management of broadcasting companies and news companies must be exercised exclusively by Brazilians, born or naturalised, for more than 10 years.

Art. 217 of Law No. 9.279 stipulates that any person domiciled abroad must appoint and maintain a duly qualified attorney domiciled in Brazil, vested with powers to represent them in administrative and judicial matters, including the authority to receive service of process. This requirement also applies specifically to those engaged in the patent application process.

Brazil is not a signatory of the 1996 World Trade Organization (WTO) Information Technology Agreement (ITA) nor the 2015 expansion (ITA II).
