Industry Overview
Lime and gypsum product manufacturing (NAICS 3274) encompasses facilities that produce quicklime, hydrated lime, and gypsum products from raw limestone, dolomite, and gypsum deposits. This industry supplies essential materials to construction, agriculture, environmental remediation, chemical processing, and steel production sectors. Lime products serve as critical inputs for water treatment, flue gas desulfurization, soil stabilization, and industrial chemical synthesis, while gypsum products are primarily used in wallboard, plaster, and joint compounds for construction applications.
The industry represents a capital-intensive, resource-dependent segment of nonmetallic mineral manufacturing. Production facilities are typically located near raw material deposits to minimize transportation costs, and the industry relies heavily on continuous kiln operations and grinding technologies. Market demand is closely tied to construction activity, environmental regulations requiring air pollution control, and industrial process requirements across diverse end-use markets. Consolidation among manufacturers has increased over the past decade, with larger companies achieving operational efficiencies and broader geographic reach.

Frequently Asked Questions
What is NAICS 3274? ▾
NAICS 3274 is the industry classification for lime and gypsum product manufacturing in the United States. It includes establishments primarily engaged in manufacturing quicklime, hydrated lime, calcined gypsum, and finished gypsum products such as wallboard and plaster. This classification is part of the broader nonmetallic mineral product manufacturing sector.
What are the primary end-use markets for lime products? ▾
Lime products serve multiple critical markets including construction (as a binding agent), environmental applications (water treatment and air pollution control), agriculture (soil amendment), steel production (fluxing agent), and chemical manufacturing (industrial synthesis). Water treatment and flue gas desulfurization represent growing demand segments due to environmental regulations.
How do raw material costs impact lime and gypsum manufacturers? ▾
Raw material costs significantly impact profitability since limestone, dolomite, and gypsum represent the primary production inputs. Manufacturers benefit from locating facilities near mineral deposits to minimize extraction and transportation costs. Vertical integration or long-term supply agreements help stabilize input costs and ensure consistent production capacity.
What regulatory factors affect this industry? ▾
Environmental regulations are primary drivers, including EPA air emissions standards for particulate matter and acid gases, Clean Air Act requirements for industrial facilities, and state-level environmental permitting. Mining reclamation requirements, worker safety regulations (OSHA), and noise ordinances also significantly impact operational compliance and capital expenditures.
What technological improvements are manufacturers implementing? ▾
Manufacturers are investing in advanced kiln technologies for improved thermal efficiency, real-time process monitoring systems for quality control, dust collection and emissions capture systems, and automation in material handling and grinding operations. These investments reduce operating costs, improve product consistency, and enhance environmental compliance.
