REACh Statement

Diamond Electronics Ltd is fully aware of the EU Regulation (EU) Nº 1907/2006, relating to the “Registration, Evaluation, Authorisation and Restriction of Chemicals” commonly known as REACh, which came into force on the 1st June 2007.

Diamond Electronics is a distributor and importer of electronic parts, supplying a wide range of components that are specified by our customers during their own product development process.

As we operate in the downstream sector of the supply chain, we continually collect data to support our ongoing risk assessment processes and obligations on REACh compliance.

By agreement, customers may pass over responsibility for their component supply chain which may/may not include the production of PCBA’s or final product assemble.

Should an “SVHC” be identified in any part of this process, above the threshold of 0.1% by weight, we will communicate the information to our customers. We will monitor legislation for additions to the range of Chemicals and/or thresholds of existing substances.

Diamond Electronics is not aware of any breaches in our supply chain with regard to products we supply within the scope of the REACh Regulation.

Conflict Minerals Statement

On July 21 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act was signed into law. This Act was introduced in an effort to end the human suffering and environmental impact associated with mining in the Democratic Republic of Congo and adjoining countries. It requires that companies disclose the extent to which their products contain so called ‘Conflict Minerals’ which are identified as including tin tungsten tantalum or gold. If present in their products, companies must determine the source of these substances. 


Diamond Electronics fully promotes the traceability of these minerals and believes that our customers should be fully informed about the products that they purchase. Whilst we are not able to certify as to the country of origin of the minerals contained in the products manufactured by our suppliers, we do request that all of our suppliers agree to supply product from responsible sources which does not contain ‘Conflict Minerals’ upon acceptance of our purchase order.

Diamond Electronics understands the importance of this issue to its customers and is fully committed to working towards a conflict free supply chain. We are aware of our responsibility to pass on any information relating to products which may contain these ‘Conflict Materials’ when identified and communicated to us by our suppliers.
