It is reported that the high cost of registering domain names represents a restriction as it is three times higher than the average for the Americas region, costing approximately USD 950.

Resolution 54 of 2018 provides a comprehensive framework for consumer protection that also applies to online transactions. Section 5 of the Resolution establishes the principles of consumer protection, while Section 6 dictates the rights of consumers. Furthermore, Chapter IV of Resolution 42 of 2020 lists consumer rights and supplier obligations.

Cuba has not signed the United Nations (UN) Convention on the Use of Electronic Communications in International Contracts.

Digital advertisement is administered and managed by Empresa de Telecomunicaciones de Cuba S.A. Advertisers who wish to publish content on the network must use the services of this state company. Other alternatives, also state-owned, are Offer, from the Cuban News Agency (ACN) and the services of Cubavisión International or Radio Taíno. Cuba has an absence of regulation in the field of communication. The most advanced in this regard is the bill on Advertising, Promotion, Public Relations, Institutional Propaganda and Public Good Propaganda drafted by a commission of the former Cuban Association of Publicists and Propagandists (ACPP).

According to Art. 8 of Decree-Law 370, the Ministry of Communications issues licenses to providers of services related to the computerisation of Cuba so that they can project, install, maintain and market computer programs and applications according to the conditions set forth in the law.

According to Art. 2 of Resolution No. 153, all entities established in Cuba to carry out export or import activities must be registered in the National Registry of Exporters and Importers. It is reported that there are costs and delays in the process of registering a company as an authorised supplier. While there is no fee to register, companies have reported that total translation and legalisation costs in both countries range from US$5,000 to US$10,000, depending on the size of the company and the number of documents required. If the company has not been in business for a period of two years, the registration lapses, and the process must begin again.

Decree-Law 46/2021, for the first time, puts the regulation and standards of private sector companies into a legal framework. Given the nature of standards and norms legislation in Cuba, where the government publishes laws through decrees approved by the Communist Party Assembly, foreign companies cannot participate in institutional bodies that establish and regulate trade norms. Decree-Law 46/2021 establishes the rules and regulations on the private sector for all micro, small and medium-sized companies that make up the private sector permitted by the state. The government establishes in Chapter IV the norms related to the control and inspection of the goods and services of the private sector. The government issues the Decree unilaterally without the participation of foreign entities.

According to Chapter II of Resolution 139/2014 on the Regulation of the Central Commercial Registry, all commercial companies must process their registration and certification for products through the office of the Central Commercial Registry. Therefore, self-certification is not allowed for local companies, nor foreign ones. It is reported that in-country testing is required.

According to the Ministry of Communications, a process is implemented that requires a homologation certificate issued after control in testing laboratories in Cuba for ICT goods. Although there is no legal framework establishing the procedures for testing, control and certification of these goods, the Ministry requires companies to pass certain tests to obtain a homologation certificate for each product or service of telecommunication and computer equipment. There are two accredited laboratories in Cuba. The first one performs tropicalisation tests. The second one handles the testing of equipment connected to telecommunications networks that use the spectrum. Through this certification process, the Ministry of Communications regulates and controls the technical and operating specifications of the systems, equipment, and devices to be used in telecommunications and computer networks in order to guarantee the interconnection between public networks, as well as the interoperability of services.

Art. 19 (e) of Resolution No. 179/08 requires that Internet access service providers must ensure that software with cryptographic systems or encrypted file transfer is not used.

Resolution No. 128/2011 regulates data private networks. Art. 2 (c) defines a private data network as a network infrastructure installed in the same location (or in different geographic locations) and interconnected among them by public and private telecommunications links managed and operated by a legal person to meet its institutional data transmission needs. Art. 19 (5) of this Resolution establishes the requirement of official approval from the Ministry of Communications to use any type of application or service supported by a private network that implies encryption of the information that is transmitted and the Ministry requires compatibility with the IPv6 Protocol for contracted services.

Although Law 118 on foreign investment does not restrict investments in the online commerce sector, the state company CIMEX, with its company Tuenvio.cu, is the only platform that offers online purchases in Cuba.

In June 2020, Cimex Corporation notified all users of the "tuenvio.cu" e-commerce platform via email about new regulations for online purchases. According to these updated regulations, users of the Tuenvio.cu platform, which facilitates e-commerce in Cuba, is limited to one purchase per day for food and toiletries combos. These restrictions were outlined in Cimex's online shopping guide, which is available on the Tuenvio.cu platform, ensuring customers were aware of the daily purchase limits.

There are no formal licensing requirements in Cuba in the electronic commerce sector. However, Cuba has only one online trading platform called Tuenvio.cu, which is managed by the state-owned company CIMEX. This, indirectly, represents a restriction that excludes foreign companies that want to seek licenses to manage an electronic commerce platform.

Art. 53 of Decree 42/2021 establishes the permission for the Cuban state communications company to block or suspend the networks used to disseminate information considered false or harmful to "public order".
