Environmental Compliance

TDK-Lambda recognises its duty and responsibilities towards promoting a sustainable environment. Our policy is to comply with applicable global legislation and to follow TDK Corporation Environmental Policy which goes beyond mandatory International laws.

In particular our focus is to ensure that hazardous substances are not present in harmful levels in either our products or our manufacturing processes and to ensure that our consumption of valuable global resources are minimised. As a designer and manufacturer of AC-DC power supplies and DC-DC converters we have a vital role to play in helping our customers minimise their consumption of electricity. We are committed to continuously introduce smaller, more efficient products to minimise power wasted through heat.


RoHS is the abbreviation for "Restriction of (the use of certain) Hazardous Substances in electrical and electronic Equipment" - Restriction of the use of certain hazardous substances in electrical and electronic equipment.

The EU Directive RoHS II (Directive 2011/65/EU) became effective on 3 January 2013 and replaced the EC Directive 2002/95/EC on RoHS I. On July 2019, the "extended" RoHS Directive came into force with new bans on the use of substances.

The following substances are regulated by RoHS:

  • Lead (Pb)
  • Cadmium (Cd)
  • Polybromic biphenyls (PBB)
  • Polybromized diphenyl ethers (PBDE)
  • Hexavalent chromium
  • Mercury (Hg)

With the amendment of the RoHS Directive by Directive (EU) 2015/863, the following 4 substances have been added to Annex II:

  • Butylbenzyl phthalate (BBP)
  • Di(2-ethylhexyl)phthalate (DEHP)
  • Dibutyl phthalate (DBP)
  • Diisobutyl phthalate (DIBP)

Homogeneous materials containing more than 0.1 percent by weight of each of the substances mentioned (Cd: 0.01 percent by weight) may not be used in electrical appliances of the equipment categories listed in Annex I of 2011/65/EU.


RoHS II contains clear and more transparent rules for granting, renewing and deleting exemptions.

Further information on the currently valid exemptions can be found on the homepage of the European Commission's Environment Section.

TDK-Lambda EMEA & Environmental Responsibility for China RoHS2 compliance

TDK-Lambda EMEA's objectives will be to:

  • Comply with all applicable legal, regulatory and corporate requirements and, if it is deemed appropriate, adopt more stringent standards for the protection of the environment and the community in which we operate.
  • Identify, monitor and minimise the Environmental impact associated with the manufacture of our products and seek to prevent any pollution from our operations.
  • Develop products that are safe to use, make efficient use of resources, and which can be reused, recycled and disposed of safely.
  • Appoint competent people to assist us in meeting our statutory duties including, where appropriate, specialists from outside the organisation.
  • Be frank and open, making this policy and our Environmental performance publicly available.

REACH is the abbreviation for „Registration, Evaluation, Authorization and restriction of Chemicals“ in accordance with Regulation (EC) 1907/2006 of 18.12.2006.

On June 1, 2007 REACH came into force as a new Europe-wide chemicals law. The European Chemicals Agency (ECHA) is responsible for monitoring the implementation and control of REACH.

Unlike European Directive 2011/65/EU on the Restriction of hazardous substances (RoHS), REACH applies to a far broader spread of industries. The purpose of the regulation is to ensure compliance with high standards of health and environmental protection.

In accordance with the REACH provisions, producers and importers of materials must obtain all data that is needed to evaluate the materials they produce or import. In addition, they must provide convincing evidence that their materials can be handled safely for all identified uses, and that adverse impacts on human health and/or the environment can thus be avoided. Registration is required for each year and each producer or importer and for every material with a volume of at least one ton.

Where a product contains substances of very high concern (SVHCs) accounting for more than 0.1 percent of the total weight, producers are required to notify their customers of this fact. Checking whether TDK-Lambda products contain SVHCs with more than 0.1 percent by mass is an ongoing process - TDK-Lambda is in close contact with its suppliers. Furthermore, TDK-Lambda is supported by the data service provider GreenSoft Technology, Inc. to ensure compliance with the various environmental regulations.

The SVHC list is updated and published regular by the ECHA: View

Conflict Minerals

“Conflict minerals,” as defined by the US legislation, currently include the metals Tantalum, Tin, Tungsten and Gold, which are the extracts of the minerals cassiterite, columbite-tantalite and wolframite, respectively. The metals are generally referred to as "3TG".

The affected metals are particularly used in the manufacture of high-tech devices such as in the electronics, automotive or construction industries.

In politically unstable areas, the trade in minerals can finance armed groups, promote forced labour and other human rights violations, and support corruption and money laundering. The minerals originating from the territories of the Democratic Republic of the Congo (DRC) and neighbouring countries (DRC region) are referred to as "conflict minerals". If the minerals come from these areas, companies must report as part of their duty of care whether the metals have been extracted responsibly, i.e. without the use of forced labour or contribution to armed groups.

Legal basis

With the Section 1502 of the Dodd Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act), a federal law came into force in the USA in 2010, which contains regulations for companies listed on the US stock exchange to deal with conflict minerals.

The EU Regulation on Conflict Minerals ((EU) 2017/821), which came into force on 1 January 2021, obliges companies to verify the origin of 3TGs in their supply chains in order to determine whether they originate from the Democratic Republic of congo (DRC) or other high-risk conflict areas. Any supplier of these companies in the scope will also be affected by regulations that require accurate verification of the origin of minerals in the supply chain, due diligence measures and reporting on these measures.
