In February of 2003, in order to reutilize of " electronic rubbish ", prevent the harmful substance from causing harmful to human health, European Union has passed: < Restriction of the use of certain Hazardous Substance on electrical and electronic equipment>(ROHS ), and it will implement on July 1 , 2006. That means export to European Union market after July 1, 2006, the electronic product can&apos;t contain the 6 kinds of harmful substances: lead , mercury , cadmium , hexavalent chromium, PBB and PBDE. According to Chinese electromechanics association, China take account for 1/4 of export market in Euro at present. After two orders are put into effect, the electric equipment products volume of export that China is influenced directly will reach 31,700 million dollars, account for 71% of total value. As Required, the products are tested while entering European Union market, once contained the hazardous material, besides punishing, the supplier should bear the responsibility of retrieve and discard the bad product, how big expenses you can imagine.

Different from the safety inspection or authentication of the electronic product, this involves the whole course, including product design, procedure design , detecting instrument , detection method , supplier assesment, purchasing, produing and soldering,etc, so there must be an effective system to manage. To respond ROHS, Chinese Government also pays great attention and issues the corresponding regulation, Ministry of Information Industry has already made " the management of prevention and control of pollution of the electronic information products ", it makes concepts such as the safe useful life of main behavior , products for pollution ,etc. to define to the electronic information products, have made detailed regulation from each link such as product design , manufacturing , description of products , packing of product. All regulations not merely apply to domestic enterprises and individual, it also suitable for imported electronic producer and importer too.

" method " is proposed, since July 1 , 2006, in electronic products, can&apos;t contain the lead, mercury , copper , hexavalent chromium, PBB and PBDE and other poisonous harmful substances. State Bureau of Quality Testing and country hold the news briefing on July 28, release 6 detection methods standard directed against European Union ROHS, these standards will be implemented since January 18 next year.

According to above, ROHS is a great obstacle (certainly this obstacle must be the global development trend in the future ) which Chinese enterprises export to European Union, so the government, enterprise and supplier, should pay more attention to ROHS. To every enterprise, the first unleaded product has a milestone meaning.
