Product overview — Barite 4.2 SG
Drilling-fluid blenders, mud-plant operators and paint manufacturers request barite bulk supplier price quotes when stocking weighting material for rig campaigns or industrial filler programmes. Ground to 200 mesh at 4.20+ SG and 90% BaSO4 minimum, our grade meets API drilling specifications — request a price quote for bulk parcels from 500 MT with mill COA.
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 4.2 SG
Barite is a dry bulk mineral — moisture control and dust management at load and discharge determine cargo quality. Contract MOQ is 500 MT — fulfilled by 1-tonne jumbo bags on flat-rack containers (~24–26 MT net per FEU) assembled into parcels of 500–2,000 MT, or pneumatic bulk tank trucks for short-haul legs to inland mud plants.
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. API drilling-grade barite at 4.20+ SG is confirmed on every mill COA — lower-density material increases weighting-agent volume per well section.
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 — Barite 4.2 SG
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.
FAQ — Barite 4.2 SG
What specific gravity do drilling contractors require from barite?
API drilling-grade barite must meet 4.20 specific gravity minimum when tested per ISO 13503-2. Lower-density material increases the volume of weighting agent needed to reach target mud weight, raising logistics cost per well section. Our export grade is milled and classified to hold 4.20+ SG on every mill COA.
How is bulk barite shipped to offshore and onshore drilling bases?
Ground barite moves in 1-tonne jumbo bags on flat-rack containers (24–26 MT per FEU), bulk pneumatic tank trucks for short-haul legs, or direct bulk vessel holds for parcels above 3,000 MT to dedicated mud-plant jetties. FOB loading uses covered conveyors to limit moisture pickup; CFR and CIF quotes include stowage planning and discharge equipment compatibility check.
