The Most Exported Types of Bentonite in 2025
Bentonite is a versatile clay used across many industries, including construction, oil drilling, agriculture, and environmental services. Its unique properties make it an essential material worldwide. In this article, we explore the most exported types of bentonite and why countries demand them so highly.
The Two Main Types of Bentonite: Sodium and Calcium
Bentonite mainly comes in two types: sodium bentonite and calcium bentonite. Each has distinct properties that suit different industries. Both types see strong global demand and dominate bentonite exports.
Sodium Bentonite – The Leading Export
Sodium bentonite tops the list as the most widely exported bentonite. Its ability to expand and form a gel when mixed with water makes it ideal for the oil and gas sector. Companies use it as drilling mud to stabilize boreholes and prevent well collapses.
Countries like the United States, China, and India lead sodium bentonite production and export. Growing global demand for oil and gas, especially from unconventional sources like shale, continues to boost the need for sodium bentonite in drilling operations.
Beyond oil and gas, sodium bentonite finds uses in civil engineering, foundries, and environmental applications such as sealing ponds and landfills. This versatility solidifies its position as the top exported bentonite type.
Calcium Bentonite – A Rising Export
Calcium bentonite also enjoys high demand, particularly in agriculture, pet care, and environmental management. Although it doesn’t swell as much as sodium bentonite, it remains highly absorbent. Farmers use it to improve soil quality, while the pet care industry relies on it for cat litter products.
In agriculture, calcium bentonite helps retain soil moisture, assisting farmers in enhancing crop growth. It also serves as a livestock feed supplement. In pet care, calcium bentonite’s moisture absorption and odor control make it popular in premium cat litter.
The United States, Greece, and Turkey rank among the top calcium bentonite exporters. As agriculture and pet care industries expand globally, especially in emerging markets, calcium bentonite exports are expected to grow steadily.
Why Are Sodium and Calcium Bentonite So Popular?
Both sodium and calcium bentonite enjoy strong demand due to their wide-ranging industrial uses. Their versatility and critical roles in essential sectors make them valuable export commodities.
Oil and Gas Industry Growth
Sodium bentonite plays a crucial role in oil and gas exploration. As companies explore new reserves, particularly in unconventional locations, they increase their need for sodium bentonite. This clay stabilizes drilling mud and seals boreholes, making it indispensable in oil extraction.
Expanding Agriculture and Pet Care Markets
Calcium bentonite benefits from the rise of sustainable farming and increasing global pet ownership. Farmers use it to improve soil retention, while pet owners prefer it for high-quality, eco-friendly cat litter. These growing markets fuel calcium bentonite exports worldwide.
In summary, sodium and calcium bentonite remain the most exported types due to their indispensable roles across vital industries. Their global demand reflects ongoing growth in energy, agriculture, and environmental sectors.
