According to the Indian Bureau of Mines (IBM), the governmental agency responsible for mineral and ore development and search, Indian exports of Bentonite clay have recorded a trend of changing volumes but constantly increasing values in recent times. The figures show that despite the times when the volume of exports decreased, the total revenues from Bentonite still rose, indicating an improved pricing environment as well as a move towards supplying high-quality grades to world markets.
Exports have more recently surged back in terms of volume, as well as registering an additional increase in value, which signifies both a rebound in shipment levels and ongoing appreciation of Bentonite on the world trade scale. The IBM report highlights that this trend captures not just India’s consistent position as a top exporter but also increasing global industries’ affinity for quality-oriented Bentonite from India.
Market Trends
Innovative Bentonite Clay Improving Metal Casting Efficiency
Producers are developing Bentonite clay grades to improve metal casting efficiency.
For example, Clariant produced GEKO OPT, a high-performance sodium Bentonite, and ECOSIL, a Bentonite-coal blend that enhances mould flowability, strength, and minimises toxic BTEX emissions, offering cleaner and smoother castings
Foundwell India launched its “Hyper Bond” grade with large montmorillonite content, superior thermal stability, and wet tensile strength
This minimises mould rejection and also improves casting quality, particularly in the case of high-pressure molding lines. These developments show how customised Bentonite solutions have an instantaneous influence on casting results, reducing defects but optimising sustainability and productivity in the foundry sector.
Negatively Charged Bentonite Clay: A Smart Way to Capture Impurities
Anionically charged Bentonite clay is negatively charged and repels positively charged impurities like excess oils, soil, and toxins. Due to electrostatic attraction, it picks up and removes the impurities efficiently.
For instance, ASEA Redox Clay Mask, which blends Bentonite clay and proprietary redox signalling molecules. The clay traps skin impurities, while redox molecules help in aiding cellular communication and regeneration. The mask cleanses and enhances skin health and allows for a freshened and rejuvenated appearance.
This is how Bentonite’s natural charge can be utilised in cutting-edge skincare products to cleanse effectively.
Market Drivers
Increase in Steel Production & Demand: Upscale the Demand of Bentonite Clay for Casting & Moulding
The steady growth in global steel demand, driven by its durability and extensive applications in construction, automotive, and infrastructure, is directly accelerating the need for bentonite clay. As a critical material in metal casting and moulding, bentonite clay demand surges subsequently.
For example, according to the India Brand Equity Foundation, from 2008 to 2025, India’s steel production has increased by 75% and domestic demand has increased by 80%.
This parallel increase in production and consumption is directly boosting the need for bentonite clay in steel casting and moulding, thereby propelling overall market growth.
Rapidly Growing Cosmetics Industry Directs Demand for Bentonite Clays
Bentonite clay has become a key ingredient in cosmetics and skincare formulations, serving multiple functions as a thickener, absorbent, filler, texturizer, and binder. These versatile properties reinforce its widespread adoption across a variety of beauty and personal care products. With the consistent expansion of the global cosmetics industry, the demand for bentonite clay is rising in parallel.
According to L’Oréal, the beauty market is growing over the years. The graph below indicates an estimated growth over the years.

This sustained growth in beauty and personal care consumption underscores the increasing reliance on bentonite clay, thereby propelling overall market expansion.
Market Restraint
Availability of Alternatives
The versatility of bentonite clay supports its adoption across industries such as construction, agriculture, and cosmetics. However, the market faces restraint from the availability of alternative materials that demonstrate comparable or even superior properties. Minerals like attapulgite, sepiolite, and synthetic clays share similar physicochemical characteristics and better flow properties, enabling them to serve as substitutes in multiple end-use industries.
Market Opportunity
Middle East Exploration: Unlocking Opportunities in Bentonite Resources
The Middle East is rich in mineral reserves, including substantial deposits of bentonite, positioning the region as a potential hub for supply. Global companies are increasingly focusing on resource-rich countries to secure access to these reserves and strengthen their raw material base.
For instance, in June 2024, the county government of Laikipia, Kenya and China’s IPL Business Ltd held discussions on mining opportunities and economic benefits in Laikipia for bentonite and other minerals.
Such exploration and investment activities not only emphasise the growing demand for bentonite clay but also create new avenues for future market growth through resource development and cross-border collaborations.
Regional Analysis
The Asia Pacific region dominated the market with a revenue share of 32.69% in 2024. This growth is driven by expanding industries such as construction and cosmetics, along with strong regional dominance in agriculture and metal manufacturing. Bentonite clay plays a critical role in these sectors, fuelling high demand across the region.
China and India are key players, exporting bentonite to numerous industries, including construction, metallurgy, agriculture, and cosmetics. For example, China was the globe’s top producer of crude steel, increasing the demand for bentonite utilised in casting and moulding, while India’s rapidly growing cosmetics market further increased the use of clay. China’s leadership in steel production and India’s rapidly growing cosmetics industry are key contributors to market expansion.
China holds the major share in the production of crude steel. Metal casting is one of the applications of bentonite clay, where it is widely used. According to Worldsteel, China held a share of 53.3% for crude steel production in 2024, which was 49.1% in 2014. This increase and dominance in steel production directs the demand for bentonite clay in China.
India’s growing cosmetics industry, with rising investments for development and manufacturing, sets a goal of reaching the world’s top 5 cosmetic markets. India Brand Equity Foundation, India will constitute 5% of the global cosmetics market and reach the top five global markets in terms of revenue.
