RoHs Compliance Statement
Diamond Electronics Ltd – RoHS Compliance Statement
Diamond Electronics Ltd acknowledges and complies with the requirements of the European Union’s Restriction of Hazardous Substances (RoHS) Directive 2011/65/EU, as amended by Directive (EU) 2015/863 (RoHS 3). This directive restricts the use of specific hazardous substances in electrical and electronic equipment to protect human health and the environment.
As a distributor, Diamond Electronics Ltd does not manufacture or modify products and therefore does not certify RoHS compliance on behalf of original manufacturers. However, all components we supply are sourced from reputable manufacturers who provide declarations of RoHS compliance in line with the directive. Compliance information is obtained directly from these manufacturers and is verified during goods-in or purchasing checks. It is not routinely retained unless required for specific documentation.
Restricted Substances and Maximum Concentration Values (MCV)
The RoHS Directive restricts the following ten substances to the maximum concentration values listed below, by weight (w/w) in homogeneous materials:
| Restricted Substance | MCV (% w/w) |
|---|---|
| Lead (Pb) | 0.1 |
| Mercury (Hg) | 0.1 |
| Cadmium (Cd) | 0.01 |
| Hexavalent Chromium (Cr (VI)) | 0.1 |
| Polybrominated Biphenyls (PBB) | 0.1 |
| Polybrominated Diphenyl Ethers (PBDE) | 0.1 |
| Bis(2-ethylhexyl) Phthalate (DEHP) | 0.1 |
| Butyl Benzyl Phthalate (BBP) | 0.1 |
| Dibutyl Phthalate (DBP) | 0.1 |
| Diisobutyl Phthalate (DIBP) | 0.1 |

Note: Where Diamond supplies custom products or assemblies under Diamond-generated part numbers, specific compliance certificates may be issued upon request.
REACh Statement
Diamond Electronics Ltd – REACh Compliance Statement
(Regulation (EC) No. 1907/2006 – Reviewed June 2025)
Diamond Electronics Ltd fully acknowledges and complies with the European Regulation (EC) No. 1907/2006, concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACh), which entered into force on 1st June 2007.
As a distributor and importer of electronic components, we operate downstream in the supply chain and do not manufacture, formulate, or chemically alter any products. We supply components as specified by our customers, based on original manufacturer data and declarations.
In accordance with Article 33 of the REACh Regulation, we are committed to ensuring that any information received from our suppliers regarding the presence of Substances of Very High Concern (SVHCs) is communicated to our customers in a timely and transparent manner, especially where the concentration exceeds the 0.1% w/w threshold in any article.
Our Compliance Process
We maintain a proactive approach to REACh compliance, including:
Regular monitoring of updates published by the European Chemicals Agency (ECHA).
Verification of supplier declarations for regulated substances.
Immediate notification to affected customers if any SVHC above the threshold is identified in supplied products.
While customers remain ultimately responsible for assuring REACh compliance for their PCB assembly (as this falls outside our direct scope), Diamond Electronics Ltd — on prior agreement — will assist in the provision of REACh compliance information for the supplied parts and assemblies.
As of the latest review in June 2025, the current list of 250 SVHCs is available on the ECHA website and may be accessed here:
ECHA Candidate List Table
Diamond Electronics Ltd is not aware of any non-compliance or breaches within our current supply chain under the scope of REACh. Should regulatory requirements change, or any risk arise, we will act promptly to assess impact and inform our customers.

Conflict Minerals Statement
Diamond Electronics Ltd – Conflict Minerals Policy
Diamond Electronics Ltd recognises the human rights and environmental concerns associated with the mining of certain minerals — specifically tin, tungsten, tantalum, and gold (3TG) — from conflict-affected and high-risk regions, particularly the Democratic Republic of Congo (DRC) and adjoining countries.
We fully support the objectives of the U.S. Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, which requires companies to disclose the use of any 3TG minerals sourced from conflict-affected regions and to promote responsible supply chains.
As a distributor, we do not manufacture products or directly source raw materials. However, we understand our role in promoting transparency and ethical sourcing practices throughout the supply chain. We expect our suppliers to:
Avoid sourcing minerals from entities that support or benefit armed conflict or serious human rights abuses.
Exercise due diligence on the source and chain of custody of 3TG minerals in line with the OECD Due Diligence Guidance.
Provide clear information on the mineral content of products, when relevant.
Supply only from sources that follow recognised responsible sourcing frameworks.
While we cannot independently certify the origin of minerals used in the products supplied to us, we strongly encourage all suppliers to provide materials that are conflict-free. Acceptance of our purchase orders assumes supplier agreement to these expectations.
Diamond Electronics is committed to working toward a conflict-free supply chain and will share information received from our suppliers with our customers where applicable. If any products we distribute are found to contain 3TG minerals from non-compliant sources, we will take appropriate measures, including supplier re-evaluation or disengagement.
