Quantity labeling: Accuracy and transparency

Like prices, the indication of quantities is a guarantee of transparency and clarity for consumers, who can therefore compare products more easily. Here is an overview of this regulation. 

In 2022, the inspections carried out by cantonal supervisory agencies revealed that, in the wholesale sector, approximately 15% of market stalls and farm stores did not comply with the principle of net weight. However, this measure is in the Quantity Ordinance (in German), which came into force on January 1, 2013. Before the law was revised, items that contained a product in bulk (bags, paper, packaging) could be included in the calculation of the total weight. Now, if a consumer asks for 100 g of cut meat, the 6 g of paper used to wrap this meat must be deducted from the total.

Labeling rules are not the same for pre-packaged products and those sold in bulk. Pre-packaging is a collection of products not packed in front of the consumer and the quantity of which cannot be changed without the packaging being opened. A retailer who makes an assortment of breads and offers the whole assortment for sale is pre-packing goods. However, if they place one kind of bread in a bag in front of the consumer, this is a product sold in bulk/wholesale.

General principles

It is mandatory to indicate the quantity of products sold in the store (barring exceptions) and the following rules must be followed (taken from the SECO information leaflet for retailers entitled "Correct indication of quantities and prices (PDF, 4 MB, 01.07.2022)", 2020 version, in German).

  • Units of measurement. Quantities must be measured according to the weight, volume, surface area, length or number of units. The net quantity is a critical factor. Units must be indicated according to the standards of the ordinance on units (kg, g, l, etc.) or as a number of items.
  • Precision. The quantity must be declared precisely without approximation.
  • The minimum quantity declared must be reached.
  • The packaging must not mislead the consumer on quantity due to its size, presentation and wording, except in the case of technical requirements. 

Pre-packaging

There are two types of pre-packaging which must carry certain information and for which different metrological requirements apply:

Type of pre-packaging Following information must appear on pre-packaging and be indelible, clearly visible and completely legible, without having to open or unfold the packaging. Metrological requirements Examples

Pre-packaging for the same nominal quantity, that is, the quantity declared on the pre-packaging.

Example: a gallon of milk.

 

The nominal volume for liquid goods.

The nominal weight for other goods.

The specific description of the goods to which the declared quantity refers.

The identity of the manufacturer or the importer.

The average value of the content should not be less than the declared quantity.

The proportion of pre-packaging presenting a discrepancy higher than the authorized values should not exceed 2.5%.

No pre-packaging should present a discrepancy higher than twice the value fixed.

 

 

For a quantity of 50 to 100 g or ml, a maximum deviation of 4.5 g or ml is tolerated.

For a quantity of 50 to 100 g or ml, a maximum deviation of 9 g or ml is tolerated.

Pre-packaging for a variable nominal quantity, or random pre-packaging.

Example: precut slices of ham in plastic packaging.

The pre-packaging must be measured and labeled individually using an officially verified weight/price labeling device.

The content should not present a discrepancy above a certain value.

It is forbidden to take systematic advantage of discrepancies tolerated.

For example, a maximum deviation of 2 g or ml for a quantity of up to 500 g. Regulations vary depending on the product.

“E” mark of conformity

Swiss manufacturers whose pre-packaging respects the standards of the European Union (EU) can affix the “e” mark of conformity and export their products without having to be checked systematically in the country of destination (this is also the case for European pre-packaging bearing the mark of conformity imported into Switzerland). The “e” mark is used for pre-packaging for the same nominal quantity of a weight of 5 g to 10 kg or 5 ml to 10 l and which meet the requirements of European Directives 76/211/EEC and 2007/45/EC. 

Wholesale

In addition to the principle of net weight, products sold in bulk must satisfy the following requirements regarding the declaration of quantity:

  • Precision. Goods weighed by the consumer or weighed by the merchant in front of them must be weighed using verified instruments.
  • Net quantity. The quantity of the goods must be measured without the packaging. The exception that allowed the weight of the protective bag to be added to the net weight of the goods, provided that this packaging does not weigh more than 2 g, is no longer applicable since January 1st 2025. There are only a few exceptions to the net sales principle: the weight of confectionery products such as pralines or sweets, sold in bulk and individually packaged in a bakery or confectionery shop, may be included in the calculation of the weight of the goods.
  • Sales by unit. Some goods can be sold by unit, such as bakery and cake products of a weight less than or equal to 150 g, some sausages or fruit such as exotic fruit or citrus fruit, herbs, and vegetables like cucumber, garlic or kohlrabi. 

Special cases

Some products have specific rules:

  • Frozen products. The ice around a frozen product should not be included in the nominal quantity.
  • Pre-packaging of goods declared according to drained weight. Goods packed in a liquid (pickles, for example) must feature a declaration of their drained weight in addition to the total nominal weight. For these products, the European “e” mark must refer to the total nominal quantity.
  • Pre-packaging of wine and spirits. The unit price indication is not compulsory when sold per 1, 2 or 5 liters and their decimal multiples or sub-multiples; for spirits in containers with a 35 cl and 70 cl nominal content.

Inspections

The Swiss Federal Institute of Metrology (METAS) closely supervises the rules relating to declared quantity. The cantonal inspection offices are responsible for metrology, inspection of pre-packaging and wholesaling. Inspections are carried out once a year for manufacturers and importers of pre-packaging. The fine for any breach can be as much as CHF 20,000 (CHF 10,000 for negligence).
