Quality and Certificates
Quality assurance at every stage
At ZUMiR, we are committed to the highest quality of our products and complete customer satisfaction.
Our microspheres and other raw materials undergo rigorous quality control—from sourcing, through cleaning and fractionation, to packaging and delivery to the customer.
Each batch is tested in our laboratory for physicochemical parameters such as density, moisture content, compressive strength, chemical composition, and particle size distribution.
Our standards and procedures
In-house quality control laboratory – We conduct regular, detailed testing of every batch of microspheres and other products.
Full batch traceability – Each delivery is marked with an individual code, enabling product tracking from sourcing to delivery to the customer.
Ongoing cooperation with accredited external laboratories – We confirm the quality of our products through independent testing.
Certificates and compliance with standards
Our operations and products meet the requirements of national and international quality and safety standards.
We hold, among others:
- Certificates of compliance with PN-EN standards for selected products
- Hygiene certificates and test reports – available upon customer request
- Compliance with REACH requirements for products exported to EU markets
Responsibility and ecology
We care not only about quality but also about the natural environment.
Our technological processes are optimized to minimize environmental impact, and the use of microspheres and other by-products of coal combustion supports the circular economy.
