According to Ar. 3 of Resolution No. 43/2019, procedures related to domain names are done through a special platform called TAD (Trámites a Distancia). To use the platforms, the residents must use their tax ID, while non-residents must obtain an identification number that is provided by Network Information Center (NIC) Argentina (Art.4). Users of this platform can appoint an agent who takes the necessary steps to register, renew and manage domain names on their behalf (Art.5).
Besides this general procedure, NIC Argentina has established some additional requirements for special ccTLDs (country code top-level domain) such as "tur.ar", "musica.ar", "gob.ar" and "org.ar". To be able to register these domain names the applicant must provide evidence that it is registered as an authorised tourist agency (for "tur.ar"), registered at the Registry of the Musical Activity of the National Institute of Music or Registry of National Musicians (for "musica.ar"), a government entity (for "gob.ar") or a non-profit organisation (for "org.ar").

The Consumer Protection Law and the Digital Signature Law provide a comprehensive framework for consumer protection that also applies to online transactions. Arts. 10 and 33 of Law 24,240 (as amended by the Consumer Protection Law 26.361 of 2008) regulate purchases through telecommunications, postal or electronic means. The law establishes that “when services, including public services, are contracted online or by phone, the provision of such services may be canceled in the same way as they were contracted, at the consumer's discretion”. In addition, the supplier has 72 hours after the cancellation of services to send a record of such cancellation (without cost) to the relevant consumer or user.

Pursuant to Art. 35 of Law No. 27,541, an emergency tax is established that is applied at the national level for five years from the law's effective date. This tax applies to the following operations: exchange of foreign currency from financial entities to pay for purchases and services abroad by means of credit cards, debit cards, or similar means of payment, including internet purchases in foreign currency and cash withdrawals or advances, as well as for the payment of services rendered by non-residents in the country, using credit cards, debit cards or any other equivalent means of payment, in the name and on behalf of the client.
According to Art. 36, the tax shall be applied to individuals, companies, estates, and other responsible persons resident in the country who carry out any of the operations mentioned in Art.35. If the operation is carried out through credit, debit or purchase cards, the tax shall apply to holders, users, additional holders and beneficiaries of extensions. The tax provided for in Art. 35 shall be determined by applying the rate of 30%, as provided for in Art. 39.

Pursuant to Communication A 6823, cash advances made abroad from local credit cards are limited to a maximum of 50 USD per transaction. Companies and individuals need to obtain prior clearance from the Central Bank before transferring funds abroad, including dividend payments, or paying for services rendered to a company by foreign affiliates. If transfers are made from their own foreign currency accounts in Argentina to their own accounts abroad, individuals do not need to obtain Central Bank approval.

Decree No. 221/2019 amended Art. 80 of the previous Decree No. 1,001 establishing a de minimis threshold, that is the minimum value of goods below which customs do not charge duties and taxes, is 50 USD (below the 200 USD threshold recommended by the International Chamber of Commerce (ICC). However, this applies only to postal shipments and to a maximum of 12 shipments per year.

According to the provisions of Art. 5 of General Resolution No. 3,550 of the Federal Tax Authority, which amends the General Resolution No. 3,450 of the Federal Tax Authority, an additional 35% is charged for the use of credit and debit cards for purchases made abroad (the additional charge established in the Resolution No. 3,450 was a 20%). This surcharge applies to:
- purchases made by Argentine residents, with credit or debit cards issued in Argentina, of goods or services outside the country;
- purchases made in foreign currency through web pages or Internet connections;
- purchases of services abroad contracted through Argentine travel agencies; and
- purchases of passenger transportation services to foreign destinations by land, air, and river.
This tax has implications both for Argentine customers using foreign websites and for foreign companies targeting the Argentine market.

According to Art. 1 of General Resolution 4,450/2019, last amended by General Resolution 5,260/2022, shipments entering through the import regime by express couriers may not exceed USD 1,000 FOB (Free on Board), weigh no more than 50 kilograms and be no more than three units of the same item. Moreover, according to Art. 7 of the Resolution, the same item cannot be imported more than five times a year.
Previously, similar measures were found in General Resolution No. 3,916/2016 and General Resolution No. 3,915/2016, both repealed in 2019.

Electrical products must display an official safety "S" mark to show that they conform with the regulations. However, due to implementation issues, it is difficult to state with certainty which products must be tested, certified and marked. All certification bodies that issue S-Mark certificates through recognition of testing done outside of Argentina also have to perform “accreditation of coincidence between the product intended to be marketed in Argentina and the one contained in the certificate issued abroad” and issue an official notification to that effect.
All regulated products must be accredited by the Argentine Accreditation Organization (Organismo Argentino de Acreditación, OAA) and recognized by the Government. Testing laboratories must similarly be accredited and recognized. Argentina recognizes foreign certification bodies and laboratories if accredited by their national accreditation agencies, in countries where reciprocity agreements to such effect are in place.
The accreditation of third-party conformity assessment bodies is not a requirement for all technical regulations implemented at the national level; determining whether this is necessary depends on the analysis undertaken during the particular drafting process. OAA regulations on the accreditation of certification bodies and laboratories are consistent with those of the international standardization organizations as contained in the ISO/IEC standards (adopted as IRAM standards).

It is reported that radiofrequency transmitter products that make use of the radioelectric spectrum or connect to the public network, which are intended to be commercialized in Argentina are subject to a mandatory homologation process issued by the "Ente Nacional de Comunicaciones" (ENACOM). The products include WiFi devices, Bluetooth, Cellular Equipment, RFID Modules, Portable Transceivers, and Wireless Gateways. Most products require testing in Argentina, and typically one to three samples are needed depending on the device. Legal representation is requires as only an Argentine supplier can apply for certification approval from ENACOM.

Argentina has established percentages of local content in the production process for manufacturers of mobile and cellular radio communication equipment operating in Tierra del Fuego province. Resolution 66/2018, which replaced Resolution 1219/2015, retains the local content requirement for certain products such as technical manuals, packaging, and labels, as established in Art. 10 of Resolution 66/2018. However, it has eliminated the local content requirement for batteries, screws, and chargers. The percentage of local content required varies from 10% to 100%, depending on the process or item in consideration. In the event that the local supply is not sufficient to meet the local content requirements, companies have the option of requesting an exemption, which will be reviewed every six months in accordance with Art. 11.

It is reported that from 2022 there is an import regime, called SIRA (Sistema de Importación de la República Argentina), which replaces the previous one (SIMI: Sistema Integral de Monitoreo de Importaciones) and also the SIRASE (Sistema de Importación de la República Argentina y Pagos de Servicios al Exterior). Telecommunication cooperative chambers have complained about the lack of import authorizations from the new system, which threatens the continuity of the services.
