NAICS 327410: Lime Manufacturing

NAICS 327410 – Lime Manufacturing encompasses the production of quicklime, hydrated lime, and limestone-based products through thermal calcination and chemical processing. This industry supports critical infrastructure, environmental remediation, and industrial manufacturing applications, including flue gas desulfurization, wastewater treatment, soil stabilization, and construction materials. In government contracting, lime products are procured for use in military base infrastructure projects, EPA-regulated environmental cleanup initiatives, and Department of Transportation roadbed stabilization efforts. Though not a high-volume procurement category, lime manufacturing plays a vital but often overlooked role in sustaining long-term public works and environmental compliance programs. No contractor data is available to identify leading firms in this NAICS code within the government contracting space. The sector is typically served by regional industrial manufacturers, small businesses specializing in mineral processing, and occasionally large industrial conglomerates with diversified materials divisions. Due to the localized nature of lime production and transportation logistics, contractors are often geographically concentrated near limestone quarries and federal project sites. No agency data is available to identify primary buyers. However, demand is likely driven by the U.S. Army Corps of Engineers for civil works projects, the Environmental Protection Agency for pollution control initiatives, and the Department of Transportation for highway and bridge construction. These agencies procure lime as a raw material for chemical processes rather than as a finished end-item, resulting in sporadic and project-specific procurement patterns. The competitive landscape is characterized by low entry barriers for local producers but high logistical constraints due to the bulk and weight of lime products, limiting national competition. Opportunities exist for contractors with established supply chains near federal construction or environmental remediation sites. Procurement is often bundled with broader construction or environmental services contracts, making it advantageous for lime manufacturers to partner with primes in civil engineering or remediation sectors.
