Self-certification is allowed in the country for radio transmission, electromagnetic interference (EMI) or electromagnetic compatibility (EMC). Vietnam allows foreign companies to self-certify that they comply with these standards, through a Supplier Declaration of Conformity (SDoC). The National technical regulation QCVN 118:2018/BTTTT requires conformity testing and conformity declaration. The supplier or manufacturer of the equipment declares the equipment meets the technical and administrative requirements. A testing laboratory recognized by the regulator tests the equipment, and the supplier registers this equipment with the regulator. These procedures are based on ISO/IEC 17050, with some modifications and requirements to be in line with the legislation framework of goods and products quality control of Vietnam.
