Our advantage
1. With a professional qualification and experienced expert technical team, we can provide you with professional consultation and services.
2. Have advanced laboratory equipment to ensure the accuracy and reliability of test data.
3. As a third-party testing and certification organization trusted by customers worldwide, we are your certificate of quality.
ANATEL certification is a mandatory certification for telecommunications equipment or related equipment by the Brazilian National Telecommunications Administration (Agência Nacional de Telecomunica??es), including wireless communication equipment, wired communication equipment and related auxiliary equipment; this certification ensures that telecommunications equipment sold in the Brazilian market meets Brazil\'s technical standards and regulatory requirements, and guarantees the product\'s quality requirements such as radio frequency, electrical safety, electromagnetic compatibility, and electromagnetic exposure. If the product entering Brazil does not complete ANATEL certification, it may face fines, seizures, and other penalties.
COC certification in Algeria is a mandatory certification for products exported to Algeria, ensuring that the products comply with the country\'s safety, quality, and technical standards. The certification process includes document review, product testing, and factory inspection. Products that pass certification can be legally sold in the local market, protecting consumer interests and promoting fair trade.
GCC certification is the abbreviation for Gulf Cooperation Council certification, which is a mandatory certification requirement for products entering the market in Saudi Arabia and other countries in the Gulf region.
