Calcium carbonate is one of the most essential raw materials in today’s paper manufacturing industry. Its wide range of benefits it has become the go-to additive for paper producers around the world.

How Calcium Carbonate is Used in Paper Manufacturing

There are two primary ways calcium carbonate is used:

As a Filler: Calcium carbonate is blended into the paper pulp to increase opacity and brightness. It replaces more expensive fiber content, reducing production costs while maintaining quality.

As a Coating Pigment: When applied to the surface of paper, calcium carbonate improves printability, smoothness, and visual appeal. It enhances ink absorption, helping achieve high-definition printing.

Market Insight: Paper Segment Leads Calcium Carbonate Demand

In 2023, the paper segment accounted for approximately 41.69% of the global calcium carbonate market share, according to industry reports. This makes paper production the largest application segment for calcium carbonate, highlighting the mineral’s central role in the industry.

Vietnam: A Calcium Carbonate Powerhouse in Asia

Vietnam has firmly positioned itself as a regional and global powerhouse for calcium carbonate production and trade.Vietnam's ability to maintain a balanced import-export structure while serving major markets to serves as a critical hub for both exports and imports of this essential mineral.

The country exported $102 million worth of calcium carbonate in 2023, reflecting strong international demand. Meanwhile, domestic consumption remains high, with over 21,000 shipments imported between October 2023 and September 2024, showing that Vietnam also plays a central role in calcium carbonate distribution across the region.
