ISO 9001 is the most well-developed quality framework in the world to date, with over 750,000 organizations in more than 161 countries/regions worldwide using it. Companies certified ISO9001 achieve international standards in various management systems, indicating the ability to consistently and stably provide customers with expected quality products.
Through environmental management system certification, it can be confirmed that this company is complied with environmental protection standards and regulations in raw materials, manufacturing process, processing methods, as well as the use and disposal.
ISO 45001 provides a framework for managing occupational health and safety risks and opportunities. The purpose and expected outcome of ISO 45001 is to prevent work-related injuries and health issues for employees and to provide a safe and healthy workplace.
An Energy Management System is a system that focuses on controlling and managing “energy” as its core element. Organizations achieve this by identifying energy factors, setting specific energy goals and objectives, and establishing an energy management system to reduce energy consumption and enhance energy efficiency.
The full name of REACH is the Registration, Evaluation, Authorization, and Restriction of Chemicals. It is a regulation aimed at ensuring the safe entry of chemicals into the European Union market and their safe use. HIFULL fumed silica has obtained a REACH certificate, indicating that this substance is considered safe for use in accordance with REACH regulations. We also get pre-registered UK-REACH, K-REACH and KKDIK.
The Turkey REACH like-law: KKDIK is closely harmonized with the EU REACH provisions and requires companies to pre-register and register substances (on their own, in mixtures or in articles) manufactured in Turkey or imported into Turkey with volumes equal to or above 1 ton per year. Our product HIFULL fumed silica gets the official approval.
