    Recommend
    • COC certification in Algeria

      COC certification in Algeria

      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.

    • Saudi Arabia GCC Certification

      Saudi Arabia GCC Certification

      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.

    • Moroccan COC certification

      Moroccan COC certification

      The Moroccan government implements strict supervision on imported electronic devices, and COC certification is a mandatory requirement to ensure that products comply with local safety, quality, and environmental standards.

    Chemical products and additives testing

    Chemical additives, especially chemical additives required by a certain industry, which are not limited to metal processing additives, plastic additives, papermaking additives, construction additives, water treatment additives, coating additives, leather additives Agent, textile printing and dyeing auxiliary, etc.
