Once you know what the potentially applicable product environmental requirements are, then it is recommended to apply a regulatory risk assessment and prioritize the standards and regulations of interest. There are many ways of performing such an assessment. For example, you can determine what is riskier in terms of product characteristics, markets, consumers, legal obligations, share-holders, etc. Your procedure should reveal your corporate choices and a specific internal form should be drafted and reflect what requirements are low medium and high risk.
As you can imagine, ”high risk” requirements will have to be prioritized. A summary should explain what is at stake in detail, if necessary, article per article, for every type of your in-scope EEE. The EU RoHS requirements are usually considered as high risk if we compare them to voluntary standards. Various countries, with national deviations, have also enacted RoHS-like regulations, such as China RoHS, Taiwan RoHS, the United Arab Emirates UAE RoHS, Russia RoHS, etc.
