In 2005, the International Material Data System (IMDS) published the Global Automotive Declarable Substance List (GADSL) for all chemical industry suppliers. This list details all the requirements regarding 3,126 reportable substances, including those which are prohibited and restricted. Each supplier downstream, from Tier 1 until the final supplier, enters the compositional data into the IMDS based on GADSL. All non-listed substance formulations must be 90% disclosed.
Producers are required to give compositional data of the products they supply. Safety Data Sheets under REACH will also compel producers to divulge their formulations. For ‘article’ manufacturers such as those in the adhesive tape industry, everyone must be conscious of the added composition of their products.
