REACH and RoHS compliance for metal powders: what industrial buyers must verify

European chemical regulations create obligations that flow through the entire supply chain, from raw material producer to final product manufacturer. For industrial buyers of metal powders, two regulatory frameworks are most frequently encountered: REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) and RoHS (Restriction of Hazardous Substances in Electrical and Electronic Equipment). Despite being often mentioned together, these regulations have different scopes, different triggering conditions and different documentation requirements. Confusing them or applying the wrong framework to a particular supply situation creates compliance risks that can result in supply disruptions, customer complaints and even market access restrictions. MEPOSO, based in Milano, Italy, maintains comprehensive regulatory documentation for all metal powders it produces and supplies, and works proactively with industrial customers to ensure that compliance requirements are met efficiently.

REACH Registration: Obligations for Producers, Importers and Downstream Users

REACH (EC 1907/2006) requires that every substance manufactured in or imported into the EU above 1 tonne per year must be registered with the European Chemicals Agency (ECHA). The registration dossier contains information on substance properties, hazards, uses and risk management measures. For metal powders, the registrant is typically the manufacturer (if based in the EU) or the importer. Downstream users - companies that use the substance in industrial processes - are not required to register, but they must verify that their use of the substance is covered by the supplier's registration and that they implement the risk management measures specified in the extended Safety Data Sheet (eSDS). Key verification points for metal powder buyers include confirming that the supplier holds a valid REACH registration for the specific substance (not merely a claim of compliance), verifying that the buyer's intended use is included in the registered exposure scenarios, reviewing the extended Safety Data Sheet for relevant risk management measures, and understanding the substance identification - particularly important for alloys, where the legal status under REACH (substance vs mixture) affects registration obligations. Copper powder (EC 231-159-6, CAS 7440-50-8) and tin powder (EC 231-141-8, CAS 7440-31-5) are both registered under REACH. Bronze and brass powders may be registered as alloys or as mixtures of their constituent metals, depending on the specific composition and the registrant's approach. MEPOSO maintains REACH registration coverage for all substances it manufactures and supplies within the EU and provides registration number references upon request.

SVHC Evaluation: The Candidate List and Communication Obligations

Substances of Very High Concern (SVHCs) are chemicals identified by ECHA as having particularly serious effects on human health or the environment, including carcinogens, mutagens, reproductive toxicants, persistent bioaccumulative substances and endocrine disruptors. The SVHC candidate list is updated twice per year, in January and July. If a substance used in or contained in a product is on the candidate list at a concentration above 0.1% by weight, suppliers have a duty to communicate this information to their customers. For metal powders, the relevant SVHCs to monitor include lead (commonly present as an impurity in copper and bronze powders), cobalt compounds (relevant for hard metal and diamond tool applications), nickel compounds (relevant for certain brazing alloys), and specific chromium VI compounds. The key obligation for metal powder buyers is to maintain awareness of which substances on the SVHC candidate list may be present in their purchased powders, even as trace impurities, and to communicate this information downstream if the concentration exceeds the 0.1% threshold. MEPOSO monitors SVHC candidate list updates proactively and communicates any changes affecting its product range to customers without delay. Full SVHC declarations are available upon request for all MEPOSO powder grades, specifying the status of each candidate list substance relative to the 0.1% communication threshold. This proactive approach ensures that our customers always have current compliance data for their own regulatory filings and supply chain communications.

RoHS Directive: Scope, Restricted Substances and Declaration Logic

The RoHS Directive (2011/65/EU, amended by 2015/863/EU) restricts the use of ten hazardous substances in electrical and electronic equipment (EEE) placed on the EU market. The restricted substances and their maximum concentration values in homogeneous materials are: lead (0.1%), mercury (0.1%), cadmium (0.01%), hexavalent chromium (0.1%), PBB (0.1%), PBDE (0.1%), and four phthalates - DEHP, BBP, DBP and DIBP (each 0.1%). For metal powder suppliers, the most relevant restricted substances are lead and cadmium, which can be present as impurities in copper, tin and bronze powders depending on raw material purity and refining process. The key point that many buyers misunderstand is that RoHS applies to finished electrical and electronic equipment, not to raw materials or intermediate products in isolation. A metal powder supplier is not directly obligated under RoHS. However, if the powder is incorporated into an article that falls within the scope of RoHS (11 product categories including industrial monitoring and control instruments), the equipment manufacturer needs to verify that the powder's contribution to the homogeneous material does not cause the finished article to exceed the concentration limits. MEPOSO provides RoHS substance declarations for all powder grades upon request, specifying the actual measured concentration of lead, cadmium, mercury and hexavalent chromium against the RoHS limits. These declarations enable downstream equipment manufacturers to perform their compliance assessment with reliable supplier data.

Substance Identification for Alloy Powders Under REACH

One of the most complex aspects of REACH compliance for metal powders is determining whether an alloy powder is a substance or a mixture under REACH definitions. This distinction has significant legal consequences for registration obligations. Under ECHA guidance, a metal alloy is generally considered a preparation (mixture) of the constituent metals rather than a substance in its own right. This means that each constituent metal must be registered individually, and the alloy supplier must ensure that the registration coverage exists for every metal present above the registration threshold. For example, a phosphor bronze powder (CuSn8P) would require registration coverage for copper, tin and phosphorus. The supplier must verify that each constituent's registration includes the alloy production use in its exposure scenarios. However, some specific alloys may qualify as UVCB substances (substances of Unknown or Variable Composition, Complex reaction products or Biological materials) if they meet certain criteria. The determination requires case-by-case analysis considering the manufacturing process, the compositional variability and whether the alloy can be defined by a unique molecular formula. Buyers should not assume that a supplier's generic REACH compliance statement covers all regulatory aspects. The correct approach is to request specific information about the registration status of each constituent metal in the alloy, the exposure scenario coverage for the intended use, and any SVHC notifications relevant to the specific alloy composition. MEPOSO provides substance-specific REACH information for all alloy grades and can explain the regulatory basis for the compliance status of each product.

Supplier Documentation Checklist for Compliance

An effective compliance documentation package from a metal powder supplier should include the following elements, which MEPOSO provides as standard practice for all industrial customers. At the supplier qualification stage: Safety Data Sheet (SDS) compliant with EU CLP Regulation 1272/2008, REACH registration confirmation with registration number references, SVHC candidate list declaration current to the latest ECHA update, RoHS substance declaration with measured analytical values for restricted substances, and product technical data sheet with complete specification. With each delivery: Certificate of Analysis (CoA) showing actual batch test results against specification for chemistry, particle size distribution and physical properties, lot number and batch traceability reference, and any deviation notices if results fall outside specification windows. On an annual or trigger basis: updated SDS reflecting any regulatory changes, updated SVHC declaration following each candidate list update published in January and July, and renewed RoHS declaration if analytical methods or detection limits have changed. Many compliance problems arise not from missing documents but from outdated documents. A supplier's SVHC declaration from three years ago does not reflect the current candidate list, which has grown substantially. Similarly, an SDS that has not been updated following CLP classification changes may contain incorrect hazard communication information. MEPOSO maintains a regulatory compliance calendar and proactively issues updated documentation to customers when regulatory changes affect their products.

Export Controls and Third-Country Regulatory Requirements

While REACH and RoHS are EU-specific regulations, metal powder buyers supplying global markets must also consider regulatory requirements in other jurisdictions. Turkey's KKDIK regulation mirrors REACH and requires separate registration for substances imported into Turkey above threshold volumes. The UK's UK-REACH regime, established post-Brexit, requires registration with the Health and Safety Executive (HSE) for substances placed on the GB market. South Korea's K-REACH has its own registration requirements, and China's MEE regulations impose notification obligations for new chemical substances. For buyers exporting finished products or intermediate materials containing metal powders, understanding which national regulations apply to the powder components is essential for maintaining market access. MEPOSO supports export-oriented customers by maintaining awareness of major regulatory developments beyond the EU, providing supporting documentation that facilitates regulatory filings in non-EU jurisdictions, and working with customers' regulatory affairs teams to address specific compliance questions related to metal powder supply. This regulatory awareness is particularly important for customers in automotive, electronics and aerospace sectors who supply global supply chains and must demonstrate multi-jurisdictional compliance for their raw material inputs. MEPOSO's technical and regulatory support team is available to discuss specific compliance requirements related to your target markets and powder applications.
