This document provides lists of chemicals previously detected in leather and guidelines for applying available chemical testing methods for leather. This information can be used by those responsible for establishing specifications for leather, particularly for parameters related to restricted chemicals. Generic lists of chemicals used in the market contain many substances that are not relevant to the leather industry. Chemicals not mentioned in this document do not need to be determined, avoiding unnecessary analytical costs. NOTE Due to the constant evolution of legal requirements and toxicological evaluation of chemical substances, this document cannot take into account all potentially critical substances.
