In the production and export of calcium carbonate powder (CaCO3), quality is not only a matter of survival but also a critical competitive advantage. Given its widespread applications across industries such as paper, glass, plastics, paints, food, and pharmaceuticals, CaCO3 powder must meet strict standards regarding purity, particle size and safety. International certifications such as ISO, ROHS, REACH, and NSF serve as quality passports, enabling Global Minerals’ CaCO3 products to conquer global markets.
Global Minerals’ Standards: A Trusted Guideline
Today’s customers are increasingly focused on rigorous product quality assessments before making purchasing decisions. For CaCO3 powder, obtaining international certifications not only assures customers but also provides a reliable foundation to evaluate compliance with industry standards.
ISO 9001 demonstrates a systematic and well-operated quality management system. ROHS and REACH certify that the product is safe for human health. NSF, specifically tailored for food and beverage industries, opens doors to demanding markets like North America and Europe. These certifications not only inspire confidence but also empower customers with comprehensive information to make wise decisions when selecting a trustworthy CaCO3 supplier.

Standards as Assurance and Convincing Factors
For manufacturers in industries like packaging, plastics, or glass, selecting a supplier of CaCO3 isn’t merely about cost—it also demands long-term quality assurance. These businesses require clear standards to prove to their own partners and customers that the entire supply chain meets the necessary requirements.
For instance, a packaging company exporting to the EU must demonstrate that its materials comply with REACH or ROHS regulations, ensuring they are free of restricted chemicals. Similarly, in the food industry, NSF standards authorize the use of CaCO3 in packaging that comes into direct contact with food—a mandatory condition in many countries.
With over 21 years of experience in mining and processing CaCO3, Global Minerals understands that these standards serve as a “universal language,” connecting suppliers with global partners effectively.

Quality is the Core Message
Internationally certified CaCO3 powder is not merely about being clean or white but is a blend of multiple critical factors:
High Purity: With a CaCO3 content of over 98%, it is a fundamental requirement across various industries.
Uniform Particle Size: Strictly controlled for specific applications – from ultra-fine particles for plastic film production to coarser grains for the ceramics industry.
Cost Efficiency: Using quality-certified raw materials minimizes waste, enhances productivity, and ultimately reduces operational costs.
Export Capability: Compliance with international standards makes the product easily accepted in premium markets like the EU, the US, and Japan.
These achievements are ensured through advanced hydraulic grinding technology, which produces CaCO3 particles with consistent size, smooth surfaces, and excellent dispersibility, enabling seamless integration with various materials.
