Trade measurement laws regulate the retail and wholesale sale of garden landscape materials.
You may sell loose garden landscape materials in any one of three ways:
Garden landscape material includes:
If you charge handling fees or surcharges for small quantities of material, you must clearly display a sign of these fees or let the customer know before they make their purchase.
If you sell a smaller quantity than the full unit of measurement—per tonne, for example—you must base the price on the full unit price. Prices can be different for smaller quantities if you clearly display or advertise the costs.
Volume is the most common way to sell garden landscape materials. To sell by volume, you must measure the material in cubic metres (m3) and can use, for example:
You can sell garden landscape materials by the tonne (t) or kilogram (kg). The weight must be determined using an NMI approved weighing instrument or verified weighbridge.
If you sell garden landscape materials by the lot (such as heap, truck or trailer load or loader bucket), you must not advertise or label it by referring to volume or weight.
If you sell pre-packaged garden landscape materials, you must:
If 45 packages or fewer have a total weight of 1 t (that is, each package weighs more than 22 kg), you can label the package in terms of the number of packages that make up 1 t (e.g. 25 bags to the tonne).
You must make the weight/volume statement:
Pre-packaged garden landscape materials can only be sold by volume (litres) if packed in accordance with Australian Standard AS4454-2012.
Read the Guide to the sale of pre-packaged goods to find out more.
You don’t need to mark label packages which exceed 150 L or 75 kg with a net measurement.
Certain pre-packaged garden landscape materials are exempt from labelling requirements, regardless of package size, these include:
If you use weighing equipment, such as a scale or weighbridge, to sell garden landscape material, you must ensure that:
You are responsible for making sure the equipment is correct at all times.
We recommend that you have all your weighing equipment checked regularly by a technician licensed by NMI (servicing licensee). For a list of servicing licensees, email firstname.lastname@example.org.
NMI employs trade measurement inspectors throughout Australia. We regularly inspect landscape material to ensure they are measuring correctly and that sellers are following the correct procedure.
If an inspector finds that you are short-measuring your customers, you could be fined up to $222,000 per offence.
