Best Gypsum Rock Producers in the World in 2026
The best gypsum rock producers in the world play an important role in supplying natural gypsum for construction, cement manufacturing, plaster production, agriculture, and other industrial applications. Natural gypsum, also known as gypsum rock, is extracted from deposits around the world and processed into different grades, sizes, and specifications according to the requirements of industrial buyers.
In 2026, the international gypsum market includes specialized mining companies, natural gypsum exporters, and large integrated building-material manufacturers. Countries such as the United States, Iran, Oman, Spain, China, and several European and Asian markets remain important parts of the global gypsum supply chain.
According to the U.S. Geological Survey, U.S. crude gypsum production alone was estimated at approximately 20 million metric tons in 2025. Global gypsum production is distributed across numerous producing countries, while international trade is particularly important for countries with large deposits and efficient port infrastructure.
This guide examines the best gypsum rock producers in the world based on factors such as natural gypsum mining activity, production capacity, export presence, processing capabilities, geographic reach, and relevance to international bulk buyers.Important: There is no universally accepted official ranking of companies based exclusively on raw gypsum rock production. Therefore, this article should be viewed as an industry guide rather than an official ranking by production volume.
How We Selected the Best Gypsum Rock Producers in the World
The best gypsum rock producers in the world cannot be identified simply by looking at the size of a company’s finished gypsum-board business.
Natural gypsum rock and finished gypsum products are different parts of the same value chain.
For this guide, companies were considered based on several factors:
- Natural gypsum mining activity
- Access to gypsum deposits
- Production and processing capabilities
- Bulk supply capacity
- International export activity
- Port and logistics infrastructure
- Geographic market reach
- Importance in the global gypsum supply chain
- Experience serving industrial customers
This approach is particularly important for buyers searching for bulk natural gypsum rock, because a company with a very large gypsum-board business is not necessarily a major exporter of raw gypsum.

A company can therefore be a very large gypsum-board manufacturer without being a major international exporter of raw gypsum rock.
This distinction is particularly important for importers looking for bulk mineral supplies.
What Makes High-Quality Gypsum Rock?
Production volume alone does not determine the suitability of a gypsum supplier.
Industrial buyers should also evaluate the technical characteristics of the material.
1. Gypsum Purity
The primary mineral in natural gypsum is calcium sulfate dihydrate:
CaSO₄·2H₂O
Higher-purity material can be preferable for applications with strict chemical requirements.
However, the appropriate purity depends on the intended application.
2. Moisture Content
Moisture can affect:
- Transportation costs
- Storage
- Handling
- Processing
- Final production efficiency
Therefore, moisture should be included in the supplier’s technical specification.
3. Particle Size
Gypsum rock can be supplied in different size ranges.
Examples include:
- 0–10 mm
- 0–40 mm
- 0–70 mm
The appropriate size depends on the customer’s processing equipment and application.
4. Chemical Composition
A professional Certificate of Analysis may include parameters such as:
- CaSO₄·2H₂O
- CaO
- SO₃
- SiO₂
- MgO
- Al₂O₃
- Fe₂O₃
- Chlorides
- Fluorides
- Insoluble matter
5. Consistency
For cement and plaster manufacturers, consistency can be just as important as the headline purity percentage.
A reliable supplier should be capable of maintaining relatively consistent physical and chemical specifications from shipment to shipment.
Major Gypsum-Producing Countries in 2026
Company-level production statistics are not consistently available for every producer worldwide.
Therefore, country-level production data can provide useful context when analyzing the global gypsum industry.
The United States remains a significant gypsum producer. USGS estimated approximately 20 million metric tons of crude gypsum production in 2025.
Oman is particularly important in international trade because of its large export volumes.
Spain is also an important gypsum-producing country and has developed a strong export-oriented gypsum industry.
Other significant gypsum-producing markets include countries in Asia, Europe, North America, and the Middle East.
Consequently, international gypsum buyers should evaluate both production capacity and export capacity.
A country may have substantial gypsum reserves but limited infrastructure for large-scale international shipments.
Why Oman and Spain Are Important for Bulk Gypsum Buyers
For companies purchasing natural gypsum in large quantities, production capacity is only one part of the purchasing decision.
Logistics can have an equally important impact on the final cost.
Important considerations include:
- Distance from mine to port
- Port loading capacity
- Bulk vessel availability
- Loading rate
- Product size
- Moisture
- Gypsum purity
- Annual production capacity
- Export infrastructure
- Ocean freight
- Destination port costs
Oman has developed a particularly important position in the international gypsum trade because large quantities of natural gypsum can be shipped by sea to Asian markets.
Spain also benefits from major natural gypsum deposits and access to Mediterranean shipping routes.
Therefore, buyers should compare suppliers based on landed cost, rather than looking only at the initial FOB quotation.
How to Choose a Gypsum Rock Supplier in 2026
Finding the best gypsum rock producers in the world is only the first step for an international buyer.
Before entering into a long-term supply agreement, buyers should conduct technical and commercial due diligence.
1. Request a Certificate of Analysis
Ask for a recent COA showing the chemical composition of the gypsum.
The analysis should match the material that will actually be shipped.
2. Verify the Mining Source
Determine whether the supplier:
- Owns the mine
- Operates the mine
- Purchases gypsum from another producer
- Acts as a trading company
Direct mining operations can provide greater traceability, although the commercial suitability of a supplier depends on the complete supply chain.
3. Confirm Available Production
Ask for realistic information about:
- Annual production
- Monthly availability
- Current stock
- Export allocation
- Maximum shipment size
This is especially important for buyers requiring thousands or tens of thousands of tonnes per shipment.
4. Confirm Particle Size
The buyer should specify the required size before requesting a quotation.
For example:
0–10 mm, 0–40 mm, or 0–70 mm
Different industrial processes require different specifications.
5. Check the Loading Port
The distance between the mine and loading port can have a significant effect on logistics.
The buyer should confirm:
- Port location
- Vessel restrictions
- Loading capacity
- Draft limitations
- Loading rate
- Bulk or container shipment options
6. Compare FOB, CFR, and CIF
A low FOB price does not necessarily represent the lowest total cost.
The buyer should calculate:
FOB Price + Ocean Freight + Insurance + Port Charges + Import Costs
This produces a more realistic comparison between suppliers.
7. Arrange Independent Inspection
For large shipments, independent inspection can help verify:
- Quantity
- Chemical composition
- Moisture
- Particle size
- Product quality
Independent laboratory testing can also reduce the risk of receiving material outside the agreed specification.
Bulk Gypsum Rock Export: What Buyers Should Know
Bulk gypsum rock is commonly transported by sea when the shipment size is large enough.
Depending on the origin and destination, suppliers may offer:
- Bulk vessel shipments
- Breakbulk shipments
- Containerized shipments
- Truck delivery
- Rail delivery
For international buyers, bulk vessel transportation can be particularly important because gypsum is a relatively high-volume mineral product.
The commercial value of the transaction therefore depends not only on the gypsum price but also on freight and handling costs.
This is why major natural gypsum export hubs with efficient ports can compete strongly in international markets.
Gypsum Rock Applications
Natural gypsum has several major industrial applications.
Cement Manufacturing
Gypsum is widely used in cement manufacturing to help regulate setting behavior.
This makes cement production one of the major industrial applications for natural gypsum.

Agriculture
Agricultural gypsum can be used as a source of calcium and sulfur and as a soil amendment in appropriate agricultural applications.
Industrial Applications
Higher-purity gypsum can also be used in specialized industrial processes where consistent mineral quality is required.
Sustainability in the Gypsum Industry
The modern gypsum industry is increasingly focused on responsible resource management.
Major areas of attention include:
- Mine rehabilitation
- Resource efficiency
- Gypsum recycling
- Reduced transportation emissions
- Energy-efficient processing
- Responsible quarry management
- Reuse of gypsum waste
Quarry rehabilitation is particularly important because mining operations can alter landscapes and local ecosystems.
Integrated producers are therefore increasingly expected to manage extraction, processing, rehabilitation, and resource efficiency as part of their overall operations.
