Premium grade minerals optimized for Southeast European industrial standards and high-throughput production lines.
Strategic integration into Southeast Europe’s fastest growing automotive, polymer processing, and building materials ecosystem.
The Republic of Serbia has emerged as a preeminent hub for manufacturing, industrial innovation, and foreign direct investment in the Western Balkans. Key industrial centers—including the Belgrade metropolitan area, Novi Sad (Vojvodina), Niš, Kragujevac, and Pančevo—are undergoing accelerated modernization across sectors including automotive supply chains, construction chemicals, plastic masterbatch compounding, rubber products, and protective coatings.
Pure Calcium Carbonate (CaCO3), spanning Ground Calcium Carbonate (GCC), Precipitated Calcium Carbonate (PCC), and surface-treated Nano Calcium Carbonate, constitutes an indispensable raw material. Modern Serbian compounding and extrusion plants demand high chemical purity (CaCO3 ≥ 98.5%), exceptional brightness (Whiteness ≥ 96–98%), strictly controlled particle size distribution (D50 down to sub-micron and nanoscale), and low oil absorption to maximize mechanical reinforcement while lowering overall production costs.
An international mineral engineering leader delivering continuous, high-volume capacity to global and European markets.
Shandong Useen Calcium Co., Ltd. specializes in a range of products, including nano-scale calcium carbonate, food-grade calcium carbonate, calcium oxide, calcium hydroxide, and light calcium carbonate. Our company owns 17 fully automated calcium oxide production lines, three calcium hydroxide production lines, and nine calcium carbonate production lines. Its annual output is 200,000 tons for nano-calcium carbonate, 200,000 tons for calcium hydroxide, 160,000 tons for light calcium carbonate, 360,000 tons for heavy calcium carbonate, and 1 million tons for calcium oxide.
Through state-of-the-art automated production, continuous online particle size laser diffraction monitoring, and strict ISO9001/ISO14001 certified manufacturing protocols, Shandong Useen Calcium ensures that factories across Serbia receive stable, batch-to-batch consistent mineral fillers. By partnering with leading multimodal logistics routes—connecting major maritime routes into European entry ports such as Piraeus, Koper, and Bar, followed by dedicated rail/road networks directly into Serbian distribution warehouses—we offer unmatched supply resilience and cost efficiency.
Fostering cutting-edge surface engineering and polymer compatibility through high-level academic alliances.
Innovation is at the core of everything we do. In recent years, we have made significant investments in R&D, focusing on the development of new technologies and next-generation calcium products. Our company has established close "industry-university-research" cooperation relationships with well-known foreign industry experts, the Institute of Process Engineering of the Chinese Academy of Sciences, Tsinghua University, China University of Geosciences, Beijing University of Science and Technology, Shandong University, etc.
Through our industry-university-research partnerships, we have established strong capabilities in applied research, product development, and advanced process engineering. These collaborations allow us to continuously evolve, improve our formulations, and meet the changing demands of global industries.
We engineer specialized crystal morphologies (calcite, aragonite) and surface modification chemistries (stearic acid, silane coupling agents, titanates) tailored specifically to Serbian clients’ polymer matrices, melt flow indexes, and extrusion speeds.
Welcome to Useen — Powering modern materials with superior mineral science.
Our materials are used across a wide range of industries including PVC pipes, automotive primers, paper, printing inks, wires and cables, sealants, rubber products, tyres, and more. Our clients rely on us for consistency, tailored solutions, and support in scaling their operations without compromising on quality. Our company is the first in China to apply nano calcium carbonate to PE blow molding products, which can replace traditional filling materials and has excellent performance.

Everything you need to know about importing, logistics, specifications, and regulatory compliance.
For rigid PVC window profiles and drainage pipes manufactured in Serbian plants, we recommend our surface-treated Ground Calcium Carbonate (GCC 1250–2500 mesh) coated with 1.0–1.2% stearic acid. This reduces plasticizer absorption, enhances screw extrusion lubrication, improves Izod impact strength, and ensures exceptional exterior weatherability under Balkan temperature extremes.
We provide full-container load (FCL) shipping directly from major Chinese export terminals to key regional seaports (e.g., Piraeus, Koper, or Rijeka), seamlessly integrated with bonded intermodal rail or direct truck freight into Serbian logistics hubs in Belgrade, Novi Sad, or Niš. All shipments include complete EUR.1 support documentation, Certificates of Analysis (COA), and moisture-proof export packaging.
Yes. Although Serbia is a candidate country aligning with EU standards, all Shandong Useen Calcium products comply strictly with European REACH regulations, RoHS directives, and relevant heavy metal limitation thresholds (Pb, Cd, Hg, Cr VI < 5ppm total). Food-grade and feed-grade CaCO3 products comply with European animal nutrition and food additive quality guidelines.
Absolutely. Our modern R&D center and automated classification lines allow custom-tailored particle cut-offs (D97/D50), customized aspect ratios, and tailored coating systems (fatty acids, silanes, aluminates) optimized for your specific resin systems—such as HDPE, PP, PVC, ABS, Polyurethane, or epoxy sealants.
