Introduction

Did you know that it is an offence for a trader to sell less than the quantity indicated. There are several ways for the consumer to be sure that the quantity indicated is the quantity received, which is outlined below. 

Loose goods

Loose goods, which could include fruit and vegetables in the supermarket, or petrol from a fuel pump, are not pre-packaged and are often sold using a measuring instrument. By law, these goods must deliver the quantity displayed on the instrument. To find out how measuring instruments are checked for accuracy, see our page on control of measuring instruments .

Pre-Packaged Goods - Information for Packers and Importers

When goods are pre-packaged they can either be individually weighed with different weight amounts or pre-packed in containers all labelled as containing the same quantity. An example of the first kind of pre-package is cheese packaged in different sizes at the delicatessen counter. These types of pre-packages must always contain at least the quantity displayed on the label.

The second type of pre-package is usually found in the supermarket and has been packed outside the store by the product manufacturer. Examples include beer, jam, coffee and biscuits, which might be packaged in a range of different types of container, such as bottles, cardboard boxes, jars or plastic wrapping. These pre-packages must comply with specific laws on quantities. The rules allow the manufacturer, within certain limits, to average the amount contained in each package within a batch, provided the overall average measurement of the quantities in all packages in the batch is equivalent to the amount marked on the label. This system of making up pre-packaged goods is commonly called the 'average quantity system' of pre-packaging.
