Textiles can contain biocidal products that have the aim of restricting the activity of microorganisms or insects, for example to inhibit odours. The Biocidal Products Ordinance (Art. 31a OBP, SR 813.12) of 18 May 2005, equivalent to the European Regulation (EU) 528/2012 (BPR), requires that appropriately treated goods be labelled accordingly. The labelling must be in the official languages of the places where the product is placed on the market.
The marking must also be clearly visible, easily legible and sufficiently durable. The marking can be placed on the packaging, the instructions for use or the guarantee certificate if there is a lack of space. The lack of space does not apply to most textiles. With regard to durability, affixing on the hangtag (alone) is therefore only compliant for products where no label can be affixed (e.g. socks).
The replacement of the marking by a QR code with a link to an information page is not accepted in practice by the enforcement authorities for the time being. There is nothing to be said against it as additional information.
