Cement Manufacturing
NAICS 327310 · United States · 2022 edition
This industry comprises establishments primarily engaged in manufacturing Portland, natural, masonry, pozzolanic, and other hydraulic cements. Cement manufacturing establishments may calcine earths or mine, quarry, manufacture, or purchase lime.
Start the review with property.
For Cement Manufacturing, the saved research highlights property, workers' compensation, environmental / pollution liability. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- How many kiln lines are in operation, and what is the total annual production capacity?
- Is there on-site limestone quarrying or blasting, or is raw material sourced externally?
- What is the current environmental compliance status — any open enforcement actions, consent orders, or pending emissions violations?
- What is the replacement cost of major processing equipment, and what is the estimated maximum downtime if a primary kiln failed?
- How is finished cement distributed — company-owned tanker fleet, third-party carriers, or both?
- What safety programs are in place for silica dust, confined space entry, and heat exposure?
- For Cement Manufacturing, what should the underwriter know about prior environmental enforcement actions, consent orders, or material pollution losses?
- For Cement Manufacturing, what should the underwriter know about adverse workers' compensation loss history, particularly occupational disease claims?

Cement manufacturing facilities crush and process limestone and other raw materials, feed them through large rotary kilns at extreme temperatures to produce clinker, then grind the clinker with gypsum and other additives to produce finished cement powder. Operations typically involve continuous heavy industrial processing, significant dust generation, large fixed equipment, and bulk material handling and storage, often with on-site quarrying or raw material extraction as well.
