Barite 4.2 SG — Drilling Mud Weighting Agent & Industrial Filler

Product overview

Barite (natural barium sulfate, BaSO₄) is the dominant weighting material in water-based and oil-based drilling fluids, where its high specific gravity raises mud density to control formation pressure without excessive solids loading. Ground to 200 mesh with 4.20+ SG, our export grade meets API drilling specifications and disperses cleanly through jet-mix hoppers at rig sites and shore-base mud plants across the Middle East, North Africa and South Asia.

Beyond oilfield service, the same mineral feeds paint and coatings mills as an inert filler that improves scrub resistance and opacity, plastics and rubber compounding lines seeking high-density filler without toxic metals, and radiation-shielding concrete pours in medical and industrial construction. Grey-white powder appearance and iron oxide capped at 1.5% keep colour-sensitive paint formulations stable while meeting the low-clay impurity thresholds mud engineers specify for barite that will not swell or gel in weighted brine systems.

Material is sourced from vein and stratiform deposits in Central Asia and MENA, crushed and milled at dedicated grinding plants with inline SG screening before bagging or bulk loading. Typical buyers include drilling-fluid blenders on term contracts tied to rig activity, regional mud-plant operators stocking ahead of exploration campaigns, paint manufacturers replacing imported Chinese barite, and construction contractors batching heavy-aggregate concrete for shielding walls. HS code 2511.10. MOQ from 500 MT on FOB, CFR or CIF terms.

Loading ports & logistics

Barite is a dry bulk mineral — moisture control and dust management at load and discharge determine cargo quality. We coordinate three principal delivery modes depending on parcel size and receiver equipment.

1-tonne jumbo bags on flat-rack containers hold approximately 24–26 MT net per FEU and suit mud plants and paint mills with bag-breaking stations and limited bulk silo capacity. Ideal for parcels of 500–2,000 MT assembled from multiple container loads on FOB Black Sea or MENA origins.

Pneumatic bulk tank trucks and hopper wagons move ground barite on short-haul routes between grinding plants and inland drilling bases or coastal transhipment terminals. Receiver must have positive-pressure silo or blow-line intake; loading uses covered conveyors to limit rain exposure.

Direct bulk vessel holds handle industrial contracts above 3,000 MT on long-haul routes to dedicated mineral jetties in India, Turkey and the Gulf. Grab-unload or pneumatic discharge at destination; FOB loading at exporter-nominated berth with draft survey. CFR and CIF quotes include stowage factor confirmation and marine insurance. Typical lead time 12–25 days from contract execution to loading window.

Packaging & documentation

Cargo ships as ground powder in 1-tonne polypropylene jumbo bags (four-loop, UV-stabilized), bulk pneumatic tank trucks or direct vessel holds — bagged form is standard for containerized export. Each lot is accompanied by a mill certificate of analysis showing BaSO₄ content, specific gravity, moisture, iron oxide and particle-size distribution, safety data sheet (SDS) per GHS, commercial invoice, packing list, bill of lading and certificate of origin.

Specific gravity is confirmed by pycnometer or mud-balance method on the COA, with sieve analysis on 200 mesh for particle-size compliance. Third-party inspection (SGS, Bureau Veritas or equivalent) at loading can be arranged on buyer request. For bulk vessel parcels, hold cleanliness certificate and loading moisture record are included in the shipping instructions package.
