Selling cane sugar and grain
Growers, handlers and buyers of grain and cane sugar must follow trade measurement laws in business-to-business and business-to-consumer transactions.
Cane sugar and grain are traded based on quantity and quality.
Quality measuring instruments
You measure the quality of cane sugar and grain using specific instruments.
Chondrometers measure density. Refer to the General Certificate of Approval 4/10/0A [63KB PDF] for pattern approval requirements and test procedures.
Grain protein measuring instruments measure protein. Refer to the:
- NMI M8 Pattern Approval Specifications for Protein Measuring Instruments for Grain [92KB PDF] [261KB DOC]
- National Instrument Test Procedure (NITP) 15.1 for Measuring Instruments for Grain Quality - Protein Measuring Instruments [365KB PDF] [1.35MB DOCX]
For cane sugar
Density hydrometers measure density. Refer to the:
- General Certificate of Approval 17/1/0 [88KB PDF] for pattern approval requirements
- NITP 17.1 for Density Hydrometers Part 1: Brix Hydrometers for Cane Juice [475KB PDF] [660KB DOCX]
Polarimeters (saccharimeters) measure sugar concentration. Refer to the:
- NMI R 14 Self-indicating Polarimetric Saccharimeters Graduated in Accordance with the ICUMSA International Sugar Scale for pattern approval requirements [325KB PDF] [1.2MB DOC]
- NITP 15.2 for Measuring Instruments for Cane Sugar Quality Part 1: Self-indicating Polarimetric Saccharimeters [185KB PDF] [1.15MB DOC]
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
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, you could be fined up to $222,000 per offence.
