what is reach?


reach is the acronym for registration, evaluation, authorization and restriction of chemicals, which is the european union's regulations on the registration, evaluation, authorization and restriction of chemicals. the scope of reach regulation is very wide, basically covering all products composed of chemical substances sold on the eu market, and can be divided into three categories: substances, mixtures and articles.


substances: products composed of a single chemical component, such as toluene, formaldehyde, etc.;

what is the weee directive?


the weee directive refers to the 2002/96/ec "waste electrical and electronic equipment (weee) directive (2002/96/ec)" adopted by the european parliament and council. recycling instructions for scrapped electronic and electrical equipment. in order to properly dispose of these huge amounts of electrical and electronic waste, maintain, protect and improve environmental quality, protect human health and use natural resources reasonably and carefully, while recycling precious resources.




the relationship between rohs and reach


rohs and reach interact in a complex and complementary way. if the product meets rohs requirements, it may not meet reach requirements, and vice versa. it may be necessary for the product to comply with both regulations. rohs specifically targets the electronics industry, while reach has a similar design but a broader focus.
