Art. 10 of the Regulation on the Approval and Certification of Telecommunications Terminal Equipment establishes that applicants possessing a type‑approval certificate issued by an international body recognised by the Telecommunications Regulation and Control Agency (ARCOTEL) need only attach that certificate to their application, with no further requirements. General Provision Two identifies the categories of terminal equipment requiring type approval, including devices for advanced mobile services (mobile telephones or other devices equipped with an IMEI that connect to the networks of advanced mobile service operators), carrier services, fixed telephony, satellite telecommunications, wireless Internet access (excluding computers and other indirect‑access devices), as well as equipment used in trunked and community communication systems. General Provision Three lists the international organisations recognised for type‑approval purposes, such as ANATEL, BIS, CMIIT, the European Community through Declarations of Conformity, ETSI, the FCC, KATS, Taiwan’s NCC, and Canada’s CEBIC.

Pursuant to Arts. 1 and 2 of Resolution No. 008-2022 issued by COMEX, imports classified under "Category B" must be below the annual limit of USD 1.600 in FOB value per fiscal year. Category B refers to consignments weighing no more than four kilograms and with an FOB value not exceeding USD 400, or its equivalent in another currency, provided that such goods are not intended for commercial purposes.

From 16 June 2025, COMEX Resolution No. 006-2025 amended the tariff schedule established by COMEX Resolution No. 002-2023. It replaced the 0% tariff for Category B courier parcels under subheading 9807.10.30.00 with a fixed customs duty of USD 20 per parcel.
The limits of USD 400 FOB and 4 kg per parcel remained unchanged, and Art. 2 expressly retained the annual limit of USD 1,600 FOB per recipient established by COMEX Resolution No. 008-2022. As every Category B courier parcel became subject to duty, the regime ceased to constitute a customs-duty de minimis regime.

Ecuador has adopted national legislation based on or influenced by the United Nations Commission on International Trade Law (UNCITRAL) Model Law on Electronic Commerce.

Art. 8 of the Regulation to the Electronic Commerce Law provides that the provision by third parties of any type of electronic services, including the sending and receiving of electronic communications, the hosting of databases, the electronic registration of data, the hosting of websites on electronic media or other similar or related services, does not give rise to liability on the part of the service provider for the content of data messages. Liability rests exclusively with the owner of the information.

Art. 37 of "Regulations Governing Subscribers to Telecommunications and Value‑Added Services" establishes that, for the provision of services under a prepaid modality, the service provider must, prior to activation, adopt all necessary measures to ensure the full identification of the subscriber or client, who must at minimum provide their full name, national identity card number, or passport number in the case of foreign nationals, together with any additional information required for verification under the applicable regulations. Art. 5 further provides that the mechanisms or procedures for contracting supplementary services, whether in prepaid or postpaid form, must be set out in the standard service agreements (adhesion contracts), and these mechanisms must ensure the full identification of the subscriber or client when accepting the conditions proposed by the provider. For postpaid services, any means that reliably guarantee full identification and acceptance of the relevant terms and conditions by the contracting parties shall be deemed valid.

According to Art. 98 of the Organic Law on Communication, all the advertising that is disseminated in Ecuadorian territory through the media must be produced in Ecuadorian territory by Ecuadorian natural persons or foreigners residing in Ecuador or produced abroad by Ecuadorian persons residing abroad or foreign legal entities whose ownership of the majority of the share package corresponds to Ecuadorians and whose payroll for its realisation and production is made up of at least 80% of Ecuadorian nationals. In addition, the importation of advertising pieces produced outside the country by foreign companies is prohibited, with the exception of what is established regarding foreign legal entities, with a majority of shares owned by Ecuadorians. According to the same article, advertising production is understood as television and movie commercials, radio spots, photographs for static advertising, or any other audiovisual piece used for advertising purposes.
Art. 55 of the General Regulations of the Organic Law on Communication clarifies that "national" advertisements encompass those produced in countries with which Ecuador has signed an integration treaty. Although the regulation does not explicitly define what constitutes an integration treaty, it has been reported that the private sector interprets this provision as a relaxation of the advertising rules stipulated by the Law. This interpretation suggests that advertising produced in member countries of the Andean Community of Nations (CAN) — comprising Colombia, Peru, and Bolivia — as well as the Southern Common Market (MERCOSUR) — including Argentina, Brazil, Paraguay, Uruguay, Chile, Colombia, Guyana, Peru, and Suriname — may be disseminated within Ecuador.

Foreign governments and businesses have reported burdensome, lengthy and unpredictable import procedures in Ecuador. Earlier reports identified duplicative inspections, extensive documentation requirements and bureaucratic procedures that could substantially delay the entry of imported goods. Although Ecuador has introduced electronic systems such as ECUAPASS and the Ventanilla Única Ecuatoriana, importers continue to face numerous prior-control documents, permits and administrative requirements.
