Product-related environmental protection

Product-related environmental protection is not a target in itself. In many cases, it results from synergies between economic advantages and to environmental compatibility. We are pursuing these opportunities in all phases of the product’s life cycle – from the conception, development, manufacture, and use, right through to its end-of-life treatment. In doing so, we are meeting internal requirements as well as our customers’ growing need for environmental conscious products.

Information on restricted substances to be provided by suppliers

European legislation like REACH and RoHS require manufacturers and suppliers to provide information about restricted substances that needs to be passed on through the supply chain. As such, Siemens AG and its affiliated companies (“Siemens”) requires suppliers to declare whether products delivered to Siemens contain any substances that are restricted by such legislation. For doing so, suppliers need to complete the Siemens Substance Declaration to begin with, which is based on the List of Declarable Substances. In cases where suppliers have products that contain restricted substances as specified through the Siemens Substance Declaration, suppliers must declare such content to Siemens. To provide the opportunity for our suppliers to increase their efficiency concerning substance declaration, Siemens is prefers the centralized database, called BOMcheck, where suppliers can insert their substance declaration.

BOMCheck: Siemens preferred Supplier Substance Declaration Method

Together with other manufacturing companies, including Philips, GE, Agfa, Hitachi, Toshiba, IBM, Intel and Canon we have been supporting an industry-wide initiative of efficient substance declaration via a web database called BOMcheck. BOMcheck provides an easy-interface method to enter the requested data for substance declaration and can be accessed by all your participating customers. We would like to encourage you to join BOMcheck and use this database to provide us with the requested substance declaration for your products. More detailed information on BOMcheck, how it can help you to provide substance data to multiple customers and how you can register can be found at:

National and international legislation pertaining to environmental protection include among others

  • Restrictions and prohibitions regarding the use of substances that could be hazardous to humans or the environment like RoHS regulation or

  • Necessity of information and registration requirements for certain substances contained in the products. Examples here include the REACH regulation according to which products such as cables fall under REACH information requirements whereas granulated plastics are affected by REACH registration requirements 


Since July 2006, the "Restrictions of Hazardous Substances (RoHS)" European Directive 2002/95/EC has banned the use of lead, cadmium, mercury, hexavalent chromium as well as the flame retardants polybrominated biphenyls (PBBs) and polybrominated diphenylethers (PBDEs).Besides the reduction of hazardous implication for humans and the environment, RoHS regulations shall improve recycling in such a way that in the long term recycling costs can be reduced.

Siemens has implemented the European Union's RoHS directive. For example we are switching to lead-free soldering methods in our manudacturing operations and avoid RoHS substances in our products. In doing so, we expect from our suppliers to be also compliant to this directive.


As part of its comprehensive product responsibility, Siemens ensures that all applicable obligations defined in REACH are fulfilled in time.

REACH - Regulation (EC) 1907/2006 is the European Chemicals Regulation concerning the Registration, Evaluation, Authorization and restriction of Chemicals. It has been in force since 2007 and replaces 40 individual laws. Its scope of validity covers all substances as such and in chemical mixtures (formally called preparations) or in selected articles and applications. The European Chemicals Agency (ECHA) is responsible for ensuring that the REACH Regulation is implemented and monitored. The aim of the Regulation is to protect human health and the environment. The REACH Regulation is considered to be one of the world's most stringent chemicals laws.

The abbreviation "REACH" derives from the English title of the Regulation: Regulation concerning the Registration, Evaluation, Authorization and Restriction of CHemicals.

The motto of REACH is "No data, no market". This means: enterprises wanting to put chemical substances, preparations and certain products on the market in the European Economic Area (EEA) are required to adhere to the following legal obligations regarding registration, evaluation, authorization, and restriction:

  • Registration: Manufacturers and importers must pre-register/register each chemical substance produced in or imported into the EEA in amounts exceeding 1 ton/year. As part of its support for Siemens AG's Special Representative on the Environment, HR EHS EP regularly carries out monitoring of the quantities of chemicals imported.

  • Evaluation: Manufacturers and importers must collect all relevant data and make this data available to the ECHA in order to evaluate the impact of each substance on human health and the environment.

  • Information: If an article contains any substance of very high concern (SVHC) in a concentration above 0.1 percent by weight, information on the SVHC and on safe use of the products must be passed along the entire supply chain. SVHCs are substances that are carcinogenic, mutagenic or toxic to reproduction, or persistent, bio accumulative and toxic substances, or very persistent and very bio accumulative substances. Bio accumulative substances accumulate in an organism e.g. by uptake from the surrounding medium or through food. The ECHA records all SVHCs in the "candidate list" which is updated every six months.

  • Authorization: The use of certain SVHCs requires authorization. These selected SVHCs are part of the authorization list (REACH Annex XIV).

  • Restriction: The REACH Regulation also pertains to the restriction of manufacturing, trading, and using certain hazardous substances, mixtures and articles. These restrictions have been in effect for some time under EEC Regulation 76/769 and were transferred to REACH Annex XVII effective June 1, 2009.

The electronics and electrical engineering industries are obligated to comply with the registration and information requirements described above and to observe all restrictions defined in REACH. The inclusion of the first substances in Annex XIV and the continuous enlargement of ANNEX XIV means that authorization is also becoming increasingly important.
