Import Barite Powder Api Grade B — Buy in wholesale FOB from Supplier in China

API grade B barite powder from Fujian Hopeland is a natural barium sulfate (BaSO4) mineral processed for use as a weighting agent in oil and gas drilling muds. The material carries a specific gravity of 4.20 minimum, with water-soluble alkaline earth metals as calcium capped at 250 ppm. Residue retained on a 75-micron sieve does not exceed 3.0%, while particles finer than 6 microns are limited to 30.0% maximum. Moisture content is held to 1% maximum, ensuring free-flowing handling at the rig site. The product is packaged in 1 MT jumbo bags, with 1.5 MT bulk bags also available.

The mineral is quarried and milled to API 13A drilling-grade specifications, with density control being the primary functional driver in drilling fluid formulation. Calcium restriction at 250 ppm protects against unwanted precipitation reactions with polymer additives in synthetic mud systems. The controlled fines fraction below 6 microns helps maintain plastic viscosity within operational limits without excessive dilution. Typical API barite for drilling applications is grey to white in colour, with minimal soluble salts and inert silica content. Standard industrial practice requires a minimum 4.20 SG for adequate hydrostatic pressure management in deep wells.

This grade of barite powder is purchased by oilfield service companies, drilling fluid manufacturers, and exploration contractors operating onshore and offshore. It is blended into water-based, oil-based, and synthetic-based drilling fluids to increase fluid density and balance formation pressure. Buyers should confirm with Fujian Hopeland the exact packaging configuration, loading port, and whether material is milled from domestic Chinese ore or imported concentrate. The supplier's location in Quanzhou, Fujian Province, offers access to Xiamen and Fuzhou ports for containerised or bulk vessel shipment.

Fujian Hopeland Imp. & Exp. Trading Co., Ltd. is based in Quanzhou, Fujian Province, China, with postal address 362005. The company operates as an import and export trading house, with its trust tier classified as harbour on the platform. The response rate is recorded at 0.00% with zero average response hours, which suggests the listing may be passively maintained or the supplier utilises alternative communication channels not captured in platform metrics. No verified trade assurance, on-site inspection, or third-party audit badges are indicated in the available data.

The supplier's profile does not disclose founding year, employee count, annual revenue, named clients, or factory ownership status. Its product focus centres on industrial minerals for oilfield applications, specifically API-grade barite for drilling fluid weighting. Buyers should independently verify the supplier's export licence, API product certification status, and whether material is sourced from owned processing facilities or third-party mills. preferred, as the available profile lacks depth on operational capacity or quality management systems.
