Clarification is given of how polymers are dealt with under the Directive 67/548/EEC. Polymers are a particular group of substances under the Directive 67/548/EEC and amendments as they are not listed in the European inventory of existing commercial chemical substances (EINECS) which otherwise lists all substances which were on the European Community Market between 1 January 1971 and 18 September 1981, the existing substances. Instead, in EINECS polymers are registered under their ultimate building blocks. With the 6th amendment to the Directive polymers become notifiable substances if containing 2% or more of new substances(s) (ie as a general rule substances not listed in EINECS), and the reporting criteria were used as definition. With the 7th amendment to the Directive an exact definition was introduced and a special test package, given in Directive 93/105/EEC, was designed for polymers to take into account their particular properties. Changing the definition of polymers created a group of substances which under the 6th amendment had been defined as polymers, and could no longer be regarded as polymers under the 7th amendment, the No-Longer-Polymers.
