The Australian Government is now operating in line with Caretaker Conventions, pending the outcome of the 2025 federal election.
Australia’s trade measurement laws regulate the measurement of pre-packaged goods by quantity.
This guide helps manufacturers, packers, importers and sellers of pre-packaged goods understand their obligations under national trade measurement laws, particularly in relation to package labelling and accurate measurement.
Under national trade measurement legislation, manufacturers, packers, importers and sellers of pre-packaged goods must:
Manufacturers, packers and importers, can choose either of two methods for determining the measurement of pre-packaged goods with common measurements or ‘constant nominal content’.
The first method is the average system where:
The second method is the Average Quantity System (AQS). Under AQS, manufacturers, packers and importers, must comply with three important rules:

These goods are known as random-weight or catch-weight packages. It is not possible to undertake a sample because while they are the same kind of product, the measurement differs. It is not meaningful to calculate an ‘average’ measurement.
The measurement of any such package – whether it is expressed as weight, volume, number, area or length – must not be less than the measurement stated on the package label. The legislation does not allow for any deficiency in even a single package’s contents.
The legislation does not allow a deficiency for ‘desiccating’ goods, other than pre-packaged fresh mushrooms or pre-packaged soap marked “mass when packed”. If the product is likely to lose weight over time through evaporation, dehydration or other means, the packer must make allowances for any expected losses in the measurement when packaging the product for the entirety of its shelf life.
All goods pre-packaged for sale must be marked with the net measurement (i.e. the weight of the contents without the packaging material).
Many pre-packaged goods which are sold by weight (especially foods such as fruit, vegetables, cheese, meat, fish and smallgoods) are sold by unit price that is price per kilogram. These pre-packaged goods should be marked in the required manner with the weight, price per kilogram and total price for the article.
Certain products do not have to be sold by weights or volume when pre-packaged, but can be sold by number or linear or area measurement. You can find a list of these products at Approval for the sale of products by number or linear or area measurement.
There are a number of detailed requirements for labelling in the national trade measurement laws to make sure that the buyer is properly informed.
The marking that states the measurement of the package (weight, volume, length, area or number) must be on the main display part of the package. It must also be shown on at least one of the other parts of the package if it is likely to be displayed to the buyer. There is an exception from this requirement for bottles or casks of wine.
When the package is substantially cylindrical, spherical, oval or conical, the measurement marking must be wholly contained within a 60 degree arc either side of the line drawn vertically through the centre of the main display panel.
The minimum character size of the measurement marking on a package depends on the maximum dimension of the package (see Table 1):
If the measurement marking is stamped or embossed instead of printed, the character size must be at least three times the minimum printed character size in Table 1. If you use an NMI-approved printing device for the measurement marking, the characters must be at least 3 mm high.
| Maximum dimension of package | Minimum character height of printed numbers/letters |
|---|---|
| 120 mm or less | 2 mm |
| Over 120 mm but not over 230 mm | 2.5 mm |
| Over 230 mm but not over 360 mm | 3.3 mm |
| over 360 mm | 4.8 mm |
The table below shows the units of measurement and the symbols allowed on measurement markings.
The degree of accuracy of a measurement marking, should not exceed three significant figures (unless the measurement marking is made by a printing device with NMI approval which allows for greater precision), e.g. 7.632 is not allowed; the correct measurement marking is 7.63.
Fractions of units must be shown as decimals and the decimal must be preceded by zero, or another numeral, e.g. ¼ kg must be shown as either 0.25 kg or 250 g.
| Measurement units allowed | Abbreviations allowed | Abbreviations NOT allowed |
|---|---|---|
| kilogram | kg | KG, Kg, kilos |
| gram | g (for any mass exceeding 1 000 g, use kg) | G, gm, grammes, grm |
| milligram | mg | MG, Mg, Mgram |
| Measurement units allowed | Abbreviations allowed | Abbreviations NOT allowed |
|---|---|---|
| litre | L (lower case l is permitted but is better to avoid) | None identified |
| decilitre | dL or dl | Dl |
| centilitre | cL or cl | Cl |
| millilitre | mL (for any volume exceeding 1 000 mL use cL, dL or L) | Ml |
| Measurement units allowed | Abbreviations allowed |
|---|---|
| cubic metre | m³ |
| cubic centimetre | cm³ (for any solid exceeding 1 000 cm³ use m³) |
| Measurement units allowed | Abbreviations allowed |
|---|---|
| metre | m |
| centimetre | cm (if length does not exceed 100 cm) |
| millimetre | mm (if length does not exceed 1 000 mm) |
For linear measurements, millimetre is also allowable:
The product name is overlapping the measurement marking.
The measurement marking is clear to read, 2 mm from the edge of the package, with a clearance of 2 mm in all directions from other graphic material or text.
The measurement marking should be printed in the same direction as the brand name.
The measurement marking is clear to read and in the same direction as the brand name.
An additional strip (such as promotional competition items) should not hide the measurement marking.
The measurement marking and product name needs to be clear to read when any additional strip is added to the package.
For goods packed in Australia, the name and address of the packer (or the person on whose behalf it was packed) must be clearly marked on the package. The address must be a street address within Australia. Post office boxes, email and website addresses are not permitted as substitutes for street addresses.
Trade measurement laws do not prescribe the size or location of the name and address of the packer, but the details must be clear and legible.
For imported food (which includes beverages and ingredients) the Australia New Zealand Food Standards Code (the Code) requires that the name and business address in Australia of the importer or seller must be clearly marked on the package. The Code is a collection of Australian and New Zealand food standards with the force of law.
Packers, importers and sellers, have a responsibility to ensure their company’s operations have systems in place to achieve compliance with the national trade measurement laws. They need to:
Packers need to make sure that their staff are fully aware of the requirements of the national trade measurement laws and can demonstrate that internal quality control systems are in place.
Importers should insist that their suppliers are aware of the requirements of the national trade measurement laws and can demonstrate that they comply with the laws in terms of quality control systems. They should have a quality control system to monitor and verify compliance of imported goods before distribution and sale.
Sellers should insist that their suppliers – both packers and importers – are aware of the requirements of the national trade measurement laws and can demonstrate that they comply with the laws and have in place quality control systems. They should have in place their own quality control system to monitor and verify compliance of the goods they sell.
While the method of checking the measurement of packages and recording the results of process and compliance sampling is not prescribed by law, the more extensive the checks and records, the more packers/importers/sellers can prove that they did everything in their power to ensure the correct measurement of the packages. The extent of these checks depends on each set of circumstances.
Packers, importers and sellers should:
Sometimes compliance sampling might indicate that packages have a shortfall, i.e. the measurement of the package is less than that stated on the label. Remedial actions must be taken if:
In either case you will need to:
Note: Even if non-compliant packages are sold at a substantial discount (or even given away) you still have to ensure that the correct measurement is marked on the package and that you comply with the trade measurement laws.
Identify the causes and take remedial action
Selling goods that don’t comply with package labelling laws can incur penalties. Where the breach is minor, however, NMI may issue a permit to sell these goods under certain conditions, including:
