According to Art. 38.7 of the Telecommunications Act, the Public Utilities Commission may, where it deems appropriate, require that an operator or a service provider puts into effect accounting separation between different portions of its telecommunications networks, facilities, and telecommunications services.

These exceptions include: (i) restricted tendering, when goods, services, or works are available only from a limited number of contractors or suppliers if the estimated cost of the contract is below the threshold of GYD 10 million (approx. USD 48,000); (ii) single source procurement: when they are available from only one source, or additional supplies are needed from an already awarded contractor if the estimated cost of the contract is below the threshold of GYD 1.5 million (approx. USD 7,200); (iii) when procurement is conducted through community participation in poor and remote communities if the estimated cost of the contract is below the threshold of GYD 5 million (approx.

Terminal equipment intended to be connected to a network open to the public must be approved by the ARN.

As the standards and technical regulations approved at the West African Economic and Monetary Union (WAEMU) level, as well as the community accreditation system, apply in Guinea-Bissau, the conformity of imported goods with technical regulations can be certified by an accredited laboratory, with a certificate of conformity mark as proof. The Scheme for the Harmonization of Accreditation, Certification, standardisation and Metrology Activities within WAEMU is based on the principle of mutual recognition among Member States at three levels: recognition of technical regulations, national standards and specifications, recognition of conformity assessment procedures and their results. Support for achieving consistency of national regimes is provided by three technical structures, one of which is the West African Accreditation System (SOAC). The purpose of introducing the SOAC was to give Member States a single organisation for accrediting conformity assessment bodies (laboratories, inspection bodies and certification bodies). The SOAC signed a Mutual Recognition Agreement with the African Accreditation Cooperation (AFRAC) and the International Laboratory Accreditation Cooperation (ILAC) in May 2022.

It is reported that in Guinea-Bissau, the de minimis threshold, that is, the minimum value of goods below which Customs Authority do not charge duties, is USD 100, below the 200 USD threshold recommended by the International Chamber of Commerce (ICC).
