No, they are not - regulatory requirements are continuously changing and evolving. Different industries can be gradually scoped in over time, and substances can be added to regulated lists frequently. In addition, regulatory requirements also change due to evolving internal goals; a company accessing a new market can have additional state, federal, and international regulatory requirements they need to comply with. This means that their supply chain will also have to report on these new requirements.
Recent examples impacting the EU market include sunsetting of exemptions provided in Directive 2011/65/EU, restriction of the use of certain Hazardous Substances in Electrical and Electronic Equipment (RoHS2) as well as the addition of four phthalates as restricted substances under the regulation. Proper product data management systems will be needed to obtain the additional information needed to phase-out future non-complaint stocks and obtain additional material knowledge of plastics used in electronic goods. On 4 June 2015, the EU commission published a new Directive (EU) 2015/863 to amend Annex II to EU RoHS 2 (Directive 2011/65/EU) that added 4 phthalates onto the list of restricted substances. The new phthalate restrictions take effect beginning July 22, 2019 for all EEE except category 8 (medical devices) and category 9 (monitoring and control instruments). Category 8 and 9 products have an additional 2 years and need to comply by July 22, 2021.
