What this class covers
ANZSIC class 2031 covers businesses engaged in manufacturing cement, lime, and related products from calcareous materials such as limestone, clay, and shale. These operations transform raw minerals through processes including crushing, heating in kilns, and hydration to produce construction and industrial materials. The classification applies to establishments whose primary activity is the production of these bulk materials rather than finished construction products.
In Australia, this includes major cement plants operated by companies like Boral and Adbri, lime production facilities supplying agricultural and industrial markets, and specialized manufacturers producing fibre cement building products. Typical operations might involve a quarry supplying limestone to a cement manufacturing plant, a kiln facility producing burnt lime for steel manufacturing, or a plant creating hydrated lime for water treatment applications. This classification helps government agencies and industry bodies track production statistics and economic activity in this fundamental construction materials sector.
Primary activities in plain English
Businesses in this class typically engage in one or more of the following activities:
- Manufacturing Portland cement and other hydraulic cements from crushed limestone and clay
- Producing lime through calcination (burning) of limestone or other calcareous materials
- Creating hydrated lime by adding water to quicklime
- Manufacturing agricultural lime for soil treatment
- Producing fibre cement products for exterior building applications
- Manufacturing cement-based cladding materials
- Producing slag cement from industrial byproducts
Exclusions and nearby codes
This class has specific exclusions that fall under other ANZSIC classifications:
Manufacturing adhesive cement is excluded from this class and is instead classified under ANZSIC 1915: Adhesive Manufacturing. Similarly, manufacturing refractory cement (used in high-temperature applications) is classified under ANZSIC 2029: Other Ceramic Product Manufacturing.
Businesses that primarily mix concrete rather than manufacture cement itself would typically fall under ANZSIC 2039: Other Concrete Product Manufacturing. The distinction is based on whether the operation involves the chemical transformation of raw materials into cementitious products versus the mixing of already manufactured cement with aggregates.
Practical guidance
For business registration and tax purposes, companies in this classification should use BIC code 20310 when completing government forms. This classification affects how businesses report activity to the Australian Bureau of Statistics and may influence eligibility for manufacturing-specific grants or programs.
Workers' compensation premiums for cement and lime manufacturing operations are typically calculated under manufacturing rates, which vary by state and territory. Businesses should ensure accurate classification as premium rates differ significantly between manufacturing, mining, and construction classifications.
Environmental regulations are particularly relevant for this industry due to emissions from kiln operations and quarry activities. Businesses should consult with state environmental protection authorities regarding licensing requirements for air emissions and waste management.
