Australia's trade measurement laws
If you're producing, importing or selling goods in your business, you need to make sure that they comply with Australia’s trade measurement laws.
What are the trade measurement laws?
Trade measurement laws cover:
- the definition of the legal units of measurement
- the use of measuring instruments for trade
- testing and verification of these measuring instruments
- transactions by measurement
- pre-packed articles (including labelling requirements)
- licensing of the businesses that verify trade measuring instruments
- licensing of public weighbridges.
Do trade measurement laws apply to me?
Businesses that sell goods by measurement, or that manufacture, pack, import or sell pre-packaged goods, are required to comply with the Australian trade measurement laws:
All businesses must comply with these laws if they:
- sell goods by measurement (such as weighing fruit and vegies for sale)
- manufacture, pack, import or sell pre-packaged goods; or
- supply or maintain measuring instruments.
What are the penalties?
NMI has a range of enforcement options for offences under trade measurement legislation.
These options include:
- a verbal warning
- a notice of non-compliance at the end of an inspection—this notice may include remedial actions that have to be carried out by the packer, importer, possessor or seller
- a written warning
- an infringement notice with associated fine
- an enforceable undertaking
- an injunction
What your business needs to do
Manufacturers, packers, importers and retailers must ensure all batches of pre-packaged articles meet the legislative requirements for correct measurement. This includes requirements for the position, size and format of measurement labels. It also includes requirements for the type and units of measurement to be used on labels for specific products.
This is usually weight or volume but can also be number or linear or area measurement.
Read NMI’s Guide to the Sale of Pre-Packaged Goods brochure for more information.

- bread and bakery products
- cane sugar and grain
- fruit and vegetables
- garden landscape materials

- precious metals and stones
- utility meters
- weighbridges used for trade.
If you use measuring instruments
If you use a measuring instrument—such as a scale—to determine the price when buying or selling goods and services, you must make sure the instrument is:
- an approved type, that is suitable for its intended purpose
- verified before use by a licensed technician or inspector
- used in the correct manner (e.g. level and indicating zero before use)
- kept clean and in good working order
- verified after each repair or adjustment.
We recommend you have your measuring instruments used for trade checked regularly by a technician licensed by NMI (servicing licensee).
For a list of servicing licensees, email email@example.com.
Approval of measuring equipment from NMI
If you use a measuring instrument for trade, its design must have NMI approval. You can ask if measuring instruments have NMI approval before you buy them.

Verifying measuring instruments
If you use a measuring instrument for trade, you must make sure it has been verified by a servicing licensee before using it. To find a servicing licensee near you, email firstname.lastname@example.org.

Trade measurement inspectors
NMI employs trade measurement inspectors throughout Australia to:
- inform, monitor and consult with businesses about their trade measurement obligations
- ensure all measuring instruments used for trade are verified and used correctly
- check pre-packaged articles for correct packer identification, measurement markings and accurate measure
- monitor the activities of servicing licensees and public weighbridge licensees
- check public weighbridges for their conditions and accuracy
- investigate complaints
- take appropriate enforcement action where there have been breaches of the laws
If an inspector visits your business, it may be a response to consumer feedback or part of our compliance program.
Inspectors can visit a place of business at any reasonable time of day and do not have to give notice of entry. We base the frequency of our visits on our risk assessment of your operations.
