Growers, handlers and buyers of grain and cane sugar must follow trade measurement laws in business-to-business and business-to-consumer transactions.

Pattern approval assesses the instrument design to ensure it is:
- fit for purpose
- able to operate in the environment in which it is expected to be used
Review the pattern approval requirements and the pattern approval guidelines and procedures relevant to your instrument.
Using measuring instruments
If you use instruments to measure mass and quality for trade, you must ensure that:
- the National Measurement Institute (NMI) has approved your type of measuring instrument
- a servicing licensee has verified your measuring instrument
- you use the measuring instrument in the correct manner
- you position the instrument so the customer can easily see the measuring process (if not, you must provide a written statement of the measurement)
- you keep the measuring instrument clean and in good working order
- a servicing licensee verifies the measuring instrument after each repair or adjustment
You are responsible for making sure your measuring instruments are correct at all times.
We recommend you have all your measuring instruments checked regularly by a servicing licensee. Contact the licensing team at firstname.lastname@example.org to find out more.
Regulating the sale of grain and cane sugar
NMI employs trade measurement inspectors throughout Australia. We regularly inspect measuring instruments to ensure sellers are following the correct process.
If we find you are short-measuring your customers, we can fine you up to $210,000 per offence.
