All businesses that sell goods by measurement or that manufacture, pack, import or sell pre-packaged goods, are required to comply with Australian trade measurement laws.

The Australian trade measurement laws are the National Measurement Act 1960 and the National Trade Measurement Regulations 2009.

The National Measurement Institute (NMI) is Australia's peak measurement organisation, responsible for maintaining the primary standards of measurement and providing the legal and technical framework for measurement standards.

For example, if you use a measuring instrument such as a scale to sell goods, you must make sure it is of an approved type and used in an approved manner. You can find out more about trade measurement law here: What Is Trade Measurement.

Manufacturers, packers and importers have a duty to carry out sufficient checks to ensure that all batches of prepacked articles meet the legislative requirements for correct measurement. You can find out more about regulations for pre-packaged goods here: Pre-packaged Goods.

NMI employs trade measurement inspectors who can visit a place of business 'at any reasonable time of day' in response to a complaint or enquiry from a consumer, or as part of a trade measurement compliance inspection program. You can find out more about your rights and responsibilities in dealing with trade measurement inspectors here: Role of Trade Measurement Inspector
