There is one approval scheme in Argentina:

This approval is mandatory for telecom and radio transmitting products that are commercialized in Argentina. 
 

Summary of ENACOM Radio Type Approval process

Radio frequency transmitting products that make use of the radio spectrum or connect to the public network, that are intended to be marketed in Argentina are subject to a mandatory approval process issued by the Ente Nacional De Telecomunicaciones (ENACOM).

In order to get Type Approval Certification in Argentina, it is mandatory to perform testing via an ENACOM Accredited Laboratory; therefore in-country testing is required according to local technical regulations, meaning that manufacturers cannot take advantage of the already performed 2014/53/EU or FCC test activity. 

Once Type testing has been successfully performed, an Argentinian supplier will need to apply for ENACOM certification approval, since foreign applicants are not allowed. This application is performed over an official online platform called HERTZ, and will be taken care by ENACOM. The validity of the certificate is three years.

ENACOM Product Marking

Once the certificate has been issued to a Local Supplier, a specific CNC ID will be issued as well. This ID must be affixed to the product as well as the CNC Regulatory Identification (Resolution 82 CNC 2015) Logo, as follows:

     CNC ID: XX-XXXX

The Regulatory Identification (CNC Logo) must be in Arial Font and have a 20 mm width. 
CNC ID must be affixed either at the right side or below the Regulatory Identification (CNC Logo).
Given the case that the Regulatory Identification (CNC Logo) cannot be affixed to the equipment,  the CNC ID label will be accepted as standalone. CNC wording must be in Century Gothic Bold font and the rest of the label (ID: XX-XXXX) must be in Arial Font. 

If labelling cannot be affixed to the equipment, it must be included on the user’s manual as well as on the equipment's packaging.
