Remarks Nowadays leather is mainly used for the production of shoes. Leather is also used in accessories, clothing, jewelry, furniture, ball covers, equestrian sports and car interiors. Many hazardous chemicals and allergens are used to tan leather. In order to check compliance with the legal limits, it is important to be able to examine these substances in a comparable way. Therefore, we have developed a comprehensive leather proficiency testing program and we are looking forward to improve the leather quality with you.
