What this class covers
ANZSIC class 2033 categorises businesses primarily engaged in manufacturing ready-mixed concrete and related products in Australia. This classification applies to operations that combine cement, aggregates, water, and other additives to produce concrete mixtures for commercial sale. The industry serves the construction sector by providing essential building materials delivered directly to project sites or sold through retail channels.
Typical operations include fixed batching plants that mix concrete for immediate delivery in specialist trucks, as well as facilities producing dry pre-mixed formulations. Businesses in this class often operate fleet vehicles equipped with rotating drums to transport and sometimes complete the mixing process en route to maintain product quality. The classification captures both large-scale operations supplying major infrastructure projects and smaller businesses serving residential construction markets.
Examples of businesses fitting this classification include: a dedicated ready-mix plant supplying construction sites across a metropolitan area; a manufacturer producing bagged dry concrete mix for retail sale; a specialist operation creating concrete slurry for tunnel grouting applications; a business producing dry mix mortar for bricklaying; and a regional operation manufacturing and delivering concrete to rural building projects.
Primary activities in plain English
Businesses classified under ANZSIC 2033 primarily engage in:
- Manufacturing ready-mixed concrete, typically produced in batching plants and transported to construction sites in agitator trucks
- Producing dry mix concrete, which is pre-mixed in dry form and packaged for later addition of water on-site
- Manufacturing dry mix mortar, used in bricklaying and other masonry work
- Producing concrete slurry, a fluid concrete mixture used for specialised applications like grouting or underwater placement
These activities involve proportioning and combining raw materials including cement, sand, aggregate, water, and chemical admixtures according to specific formulations and quality standards.
Exclusions and nearby codes
ANZSIC 2033 specifically excludes businesses whose primary activity falls outside ready-mixed concrete manufacturing. Nearby classifications include:
Businesses primarily engaged in manufacturing concrete products such as pipes, blocks, or pre-cast structural components are classified under ANZSIC 2031: Concrete Product Manufacturing. Operations focused on cement production itself fall under ANZSIC 2032: Cement and Lime Manufacturing.
Contractors who primarily pour, place, and finish concrete at construction sites rather than manufacturing the concrete would typically be classified under construction divisions rather than manufacturing. Businesses manufacturing plaster products are classified separately under ANZSIC 2034.
Practical guidance
Businesses operating in ready-mixed concrete manufacturing should use Business Industry Code (BIC) 20330 when completing Australian Business Register updates and tax documentation. This code aligns with the ANZSIC classification for statistical reporting purposes.
For Australian Business Number (ABN) registration and GST purposes, businesses must accurately describe their primary activity. Those with annual turnover exceeding $75,000 must register for GST, and proper record-keeping of material inputs, production volumes, and deliveries is essential for compliance.
Workers' compensation insurance classifications may vary by state but typically fall under manufacturing or quarrying categories depending on whether the operation includes aggregate extraction. Businesses should consult their state authority for precise classification.
When applying for industry-specific grants or reporting to statistical agencies, using the correct ANZSIC code ensures accurate classification. Businesses expanding into related activities like concrete product manufacturing may need to review whether multiple classifications apply.
