Top Grey Cement Suppliers in the World (2026)

Buyers searching for the top grey cement suppliers usually want the same thing: scale, reliability, and consistent quality. This list ranks the ten producers that dominate global grey cement supply in 2026, based mainly on installed production capacity, according to Global Cement Magazine’s Top 100 2026 report and Statista. We also cover a major 2025 restructuring that changes how the rankings should be read this year.

One important note before the list: in June 2025, Holcim completed the spin-off of its North American business, now trading independently as Amrize. As a result, older “top cement supplier” articles that still count Amrize’s volume inside Holcim’s totals are already out of date. Therefore, this list treats both companies separately, which is a more accurate picture of the market today.

1. China National Building Material Co. (CNBM) — China

CNBM currently holds the title of the world’s largest cement producer by installed capacity, according to recent Statista data. Consequently, it tops most lists of the top grey cement suppliers in 2026.

• The company is state-owned and headquartered in Beijing. Notably, it has grown rapidly through consolidation with other major Chinese producers, including Sinoma.

• CNBM also produces gypsum board, fiberglass, and other building materials. However, cement remains its largest single business line by volume.

2. Holcim — Switzerland

Holcim remains one of the top grey cement suppliers worldwide, even after its 2025 restructuring. The company now focuses on 45 markets across Europe, Latin America, Asia, the Middle East, and Africa.

• Holcim operates roughly 180 cement plants outside North America. In addition, it holds strong positions in aggregates and ready-mix concrete.

• The company has also invested heavily in low-carbon cement technology. This focus is likely to shape its competitive position among global suppliers for years to come.

3. Anhui Conch Cement — China

Anhui Conch ranks as one of the largest and most consistent top grey cement suppliers in China. It operates roughly 32 major production plants.

• In total, annual capacity sits at close to 300 million tonnes. Even so, the company sells about 97% of its output domestically, with only a small share exported.

• Anhui Conch is headquartered in Wuhu, in China’s Anhui province. Meanwhile, it has expanded into Laos, Indonesia, Cambodia, and Myanmar in recent years.

4. UltraTech Cement — India

UltraTech is India’s largest cement producer and a key name among global grey cement suppliers. It is the flagship cement business of the Aditya Birla Group.

• Notably, the company also produces white cement and ready-mix concrete. Therefore, it competes across several product categories, not just standard grey cement.

• UltraTech operates primarily across India, though it has some presence in neighboring markets. Its scale makes it one of Asia’s most closely watched cement companies.

5. Heidelberg Materials — Germany

Formerly known as HeidelbergCement, this German company remains firmly among the top grey cement suppliers globally. It was founded back in 1874.

• Heidelberg Materials operates in more than 60 countries. Specifically, its plant network includes roughly 79 cement facilities.

• The company has pushed hard into carbon capture technology at several plants. This positions it well as European carbon regulations tighten further.

6. CRH plc — Ireland

CRH is one of the world’s largest building materials companies and a major force among top grey cement suppliers. It is now primarily listed in the United States.

• The company operates across a wide network of cement, aggregates, and concrete businesses. Indeed, its scale comes largely from decades of acquisitions across Europe and North America.

• CRH has increasingly focused on integrated construction solutions. As a result, cement is just one part of a much broader materials portfolio.

7. Cemex — Mexico

Cemex remains a familiar name among the top grey cement suppliers, especially across the Americas. It was founded in 1906 and is headquartered near Monterrey.

• The company operates in more than 50 countries and territories. Moreover, its cement, aggregates, and ready-mix concrete businesses are tightly integrated.

• Cemex has also invested significantly in digital logistics tools. This has helped it manage delivery efficiency across a large, dispersed plant network.

8. Amrize — United States and Canada

Amrize is the newest name among the top grey cement suppliers, though its plants are far from new. It was spun off from Holcim in June 2025 and now trades independently.

• The company inherited over 1,000 sites across North America. In addition, it employs roughly 19,000 people across the United States and Canada.

• Because Amrize now reports separately, buyers comparing supplier scale should treat it as distinct from Holcim. This matters for anyone benchmarking supplier size using older reports.

9. China Resources Cement — China

China Resources Cement is a major regional player and a notable entry among top grey cement suppliers in Southern China. It benefits from strong regional infrastructure demand.

• The company operates a significant network of integrated cement plants. Notably, its parent group, China Resources, is one of China’s largest state-owned conglomerates.

• Regional demand in Southern China and nearby export markets continues to support the company’s production volumes.

10. Buzzi S.p.A. — Italy

Buzzi rounds out this list of top grey cement suppliers with a strong European and North American footprint. The Italian company has grown through decades of international acquisitions.

• Buzzi operates cement plants across Europe, the United States, and parts of Eastern Europe. As a result, this diversified footprint helps balance regional demand swings.

• The company has also emphasized sustainable cement formulations in recent years. This mirrors a broader industry shift toward lower-carbon products.

How to Choose Among Top Grey Cement Suppliers

Company size is only part of the picture when evaluating top grey cement suppliers for a specific project or trade relationship. Several other factors matter just as much.

• Consistent quality certification matters more than raw scale. In fact, a mid-sized supplier with strong, documented quality control can outperform a larger one with looser standards.

• Logistics and shipping capability often decide real-world reliability. Buyers should confirm port access, packaging standards, and realistic lead times before committing to volume.

• Price stability matters as much as the headline price. Our cement market analysis covers how energy costs and carbon regulation are reshaping cement pricing worldwide.

• Product-type clarity avoids costly mistakes. Buyers comparing OPC and SRC cement, for example, should review our guide to the difference between OPC and SRC cement before finalizing specifications.

Where Iran Fits Into the Global Grey Cement Picture

Iran does not appear among the ten largest global producers by installed capacity. Even so, it remains a significant regional supplier, particularly for markets across the Middle East, South Asia, and the South Caucasus.

• Iranian producers benefit from low energy costs and proximity to several fast-growing regional markets. As a result, this keeps Iranian grey cement and clinker competitively priced for nearby buyers.

• For a deeper look at sourcing directly from Iranian producers, see our 2026 clinker suppliers guide and our broader cement clinker guide.

Conclusion

The list of top grey cement suppliers looks different in 2026 than it did just one year earlier. The Holcim-Amrize split alone changes how several rankings should be read. Meanwhile, Chinese producers continue to dominate by sheer volume, even as European and North American companies push harder into low-carbon cement technology.

Whether you are comparing global producers or sourcing from regional exporters, the fundamentals stay the same: verify capacity, certification, and logistics before committing to a long-term supply relationship.
