We mainly test textiles from the clothing, toy, home textile, technical textile, furniture and automotive sectors. In these areas, we also check the packaging, inserts and care labels. Jewellery and plastic articles are also part of our range to be tested. Furthermore, we are the world’s leading laboratory for testing tattoo and permanent make-up colours. For examples please have a look here. We are happy to refer you to partner laboratories if we are unable to test your article here.

Our turnaround time is usually 10 working days. However, different inspections may need more or less time due to the scope of the inspection. There is also the possibility of placing an express order for an additional 50%. Depending on the feasibility, you will then receive your result within 3 working days.

For a quotation, please contact the administrative office, which will then forward you to the responsible person. For an overview of our prices, please request our catalogue.

We will be happy to advise you on which tests make sense for your item. This cannot be said as a general rule, but depends on various factors, such as in which country or with which supplier the article is to be sold. Basically, there are always legal regulations, especially in the area of harmful substances. However, there may also be legal requirements in the area of technical properties, for example for articles that are used in the hotel industry. Therefore, we are happy to advise you on how to bring your article onto the market in a roadworthy manner or to meet certain requirements.
