On November 25, 2025, Brazil's National Telecommunications Authority (ANATEL) issued Ato.  No. 18086, which updates the import rules related to conformity assessment, which will come into force on May 25, 2026.

• Import of product samples for certification testing: According to the new rules, importers can bring product samples into Brazil, but only for the number of samples required for the test, and any remaining samples will be retained until the final certificate of conformity is issued; Sample release requires a formal service agreement between the importer (or subsequent certificate holder) and an ANATEL designated certification body or authorized testing laboratory. The agreement must clearly specify the product model, manufacturer, and the exact quantity to be evaluated; Even products transported by post or courier are subject to compliance checks by ANATEL and the Brazilian Federal Tax Agency.
• Import of approved products for commercialization: Only the certificate holder or his legal representative can import approved telecommunications products into Brazil. Each product must be affixed with the ANATEL certification mark in accordance with the relevant marking procedures; Import documents must be filled with the product's certificate number in the "Additional Information" column to ensure smooth customs clearance and supervision.
