Import Barium Sulfate — Buy in wholesale FOB from Supplier in China

Barium sulfate (BaSO4), commonly called barite, is a dense white mineral compound with a molecular weight of 233.39 g/mol and a standard density of 4.3-4.6 g/cm3. This listing from Shijiazhuang Kunmai Chemical Technology Co., Ltd. in Hebei Province, China, offers the material as a fine white powder for industrial applications. The compound is chemically inert, insoluble in water, and resistant to acids, alkalis, and organic solvents at normal temperatures. Its high specific gravity and low oil absorption make it functional as a weighting agent and filler across multiple sectors.

Industrial barium sulfate is typically mined from natural barite ore or produced synthetically through precipitation methods. The synthetic route yields higher purity grades suitable for medical and food-contact applications, while natural grades serve drilling and coatings markets. This material is non-toxic and non-flammable, with a Mohs hardness of 3.0-3.5, meaning it causes minimal wear on processing equipment. Standard commercial grades range from 92% to 99% BaSO4 content, with the balance consisting of silica, iron oxide, and other trace minerals from the source ore.

Primary buyers include oilfield service companies drilling for oil and gas, where barite slurries control formation pressure in high-density drilling fluids. The paints and coatings sector uses it as a filler and extender pigment, while plastics compounders value its density and chemical stability. Medical device manufacturers incorporate pharmaceutical-grade material into contrast agents for gastrointestinal radiography. Importers should confirm the supplier's grade designation, particle size distribution, and whether the material is natural or precipitated before requesting samples.

Shijiazhuang Kunmai Chemical Technology Co., Ltd. operates from the High-Tech Zone in Shijiazhuang, Hebei Province, China. The company's registered address places it in a northern Chinese industrial hub with established chemical manufacturing and logistics infrastructure. The supplier holds a harbor trust tier designation on the platform, which represents a baseline verification level rather than an advanced credential. The response rate shown as zero and average response hours at zero indicate either limited transaction history through the platform or data not yet populated from buyer interactions.

The listing presents barium sulfate as a multi-industry mineral compound without specifying whether the supplier sources natural barite ore or operates precipitation manufacturing capacity. No factory size, production volume, or export license details appear in the available profile data. The company markets material for drilling fluids, paints, plastics, rubber, and medical imaging, suggesting either broad sourcing capabilities or trading operations across multiple grades. Buyers should verify the supplier's actual manufacturing scope, quality control protocols, and whether they offer precipitated versus natural grades before committing to volume orders.
