ACC uses classification units (CU) to group together business activities with a similar risk of work-related injury. These are used to assist ACC in working out levies and are based on the Australian and New Zealand Standard Industrial Classification (ANZSIC) system. There are over 500 individual industry classifications, which are grouped into 17 broad risk groups, such as Agriculture, Retail Trade and Manufacturing.
What is my classification unit?
We use your Business Industry Code (BIC) to determine your classification unit. Find out more about BIC at the Business Industry Description website (external link).
Can I have more than one classification unit?
An individual can only have one classification unit but businesses may have more than one classification unit.
Self-employed and shareholder-employees
Individuals can only have one classification unit. If you have changed business activity during the year, or believe your levies are based on the wrong classification unit, contact the ACC Business Service Centre.
Small, medium or large businesses
Businesses with more than one distinct business activity may qualify for two or more classification unit rates. Contact the ACC Business Service Centre if you think this is the case, or if business activity has changed during the year.
What are classification unit rates?
Classification unit rates are based on the actual cost of work-related injuries that have occurred in each classification group.
You can find your current classification unit rate by using our levy calculator, or downloading the booklet ACC5820 ACC Levy Rates Guidebook 2011/2012 (PDF 5.3M).
