On December 31, 2025, the Ministry of Science and Technology (MST) of Vietnam issued Circular No. 52/2025/TT-BKHCN, promulgating the National Standard for Electromagnetic Compatibility of Terminal Equipment and Auxiliary Equipment for Mobile Communication Systems (QCVN 86:2025/BKHCN), aiming to standardize the technical requirements for electromagnetic compatibility of equipment related to the field of information technology and telecommunications. The international standard corresponding to this standard is ETSI EN 301 489-52 V1.3.1. The new standard will come into effect on February 15, 2026, replacing the QCVN 86:2019/BTTTT standard issued by the former Ministry of Communication and Information. According to the provisions of the transition period, appicants can voluntarily choose to conduct testing and compliance declarations according to the new or old standards before December 31, 2026; From January 1, 2027, the new standards must be fully implemented for relevant equipment. For devices with specific HS codes (e.g., 8517.13.00, 8517.14.00, 8517.62.59), the new standard will replace the original QCVN 86:2019/BTTTT or QCVN 18:2022/BTTTT (EMC standard for wireless communications). It is worth noting that from September 16, 2026, the relevant technical requirements for GSM (2G and 2.5G) technology will no longer apply, marking the gradual phase-out of traditional communication technologies and promoting technological upgrading in Vietnam.
