It aims to protect human health and the environment from hazardous chemicals.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>SVHC Disclosure Requirements<\/strong><br>Suppliers must identify and disclose Substances of Very High Concern (SVHCs) present in their products if they exceed specific concentration thresholds. This information must be provided to customers and authorities, ensuring transparency and compliance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>SCIP Database Obligations<\/strong><br>Exporters are required to submit detailed information about restricted substances in products to the SCIP (Substances of Concern In articles, as such or in complex objects) database. This helps authorities track hazardous substances and manage waste disposal effectively.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Annex XVII Restrictions<\/strong><br>Certain chemicals are restricted under Annex XVII of REACH, limiting or banning their use in specific applications. For power semiconductors, understanding these restrictions is crucial to avoid non-compliance and market access issues.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>REACH Documentation and Supplier Data<\/strong><br>Exporters must maintain comprehensive technical files, including supplier declarations and test reports, to demonstrate compliance. Reliable supplier data on chemical substances is essential for accurate reporting and ongoing compliance management.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Staying on top of REACH requirements, especially regarding SVHC disclosures and SCIP reporting, is vital for seamless export to the EU market and to avoid penalties or delays.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">RoHS vs. REACH for Power Semiconductor Exporters<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding which regulation applies is crucial.\u00a0RoHS\u00a0focuses on limiting specific hazardous substances in electrical and electronic products, including power semiconductors. It primarily targets product design and material restrictions.\u00a0REACH, on the other hand, covers the broader chemical safety of substances used in manufacturing, including SVHCs (Substances of Very High Concern) and supply chain transparency.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Passing RoHS compliance doesn\u2019t automatically mean REACH compliance. RoHS limits specific restricted substances, but REACH requires detailed disclosure of all SVHCs and may impose additional obligations like SCIP database reporting. For export teams, this means separate assessments are necessary.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Practical compliance comparison:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Aspekt<\/th><th>RoHS<\/th><th>REACH<\/th><\/tr><\/thead><tbody><tr><td>Focus<\/td><td>Restricted substances in products<\/td><td>Chemical safety and supply chain transparency<\/td><\/tr><tr><td>Geltungsbereich<\/td><td>Specific substances (e.g., lead, mercury)<\/td><td>All SVHCs and chemicals in articles<\/td><\/tr><tr><td>Testing<\/td><td>Homogeneous material testing<\/td><td>Supplier declarations, chemical analysis<\/td><\/tr><tr><td>Documentation<\/td><td>Declaration of conformity<\/td><td>SVHC disclosures, SCIP dossiers<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Export teams must ensure compliance with both regulations independently. Relying solely on RoHS clearance isn\u2019t enough to meet REACH requirements. A comprehensive approach involves mapping materials, verifying supplier declarations, and maintaining ongoing change control to stay compliant and avoid disruptions in the global market.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A Step-by-Step Compliance Workflow for Power Semiconductor Exports<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Ensuring compliance with RoHS and REACH regulations requires a clear, structured process. Here\u2019s a practical workflow to help streamline your export compliance:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Step 1: Map the Full Bill of Materials (BOM)<\/strong><br>Start by thoroughly documenting every material and component used in your power semiconductor products. Accurate BOM mapping is essential for identifying restricted substances and ensuring traceability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Step 2: Collect Supplier Declarations<\/strong><br>Obtain compliance declarations from your suppliers, confirming that materials meet RoHS and REACH standards. Reliable supplier statements are crucial for demonstrating compliance and avoiding future risks.

Here\u2019s a checklist for power semiconductor exporters to maintain accuracy and readiness:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>RoHS Declaration of Conformity:<\/strong>&nbsp;Confirms the product meets RoHS restrictions on hazardous substances.<\/li>\n\n\n\n<li><strong>REACH SVHC Declaration:<\/strong>&nbsp;Discloses presence of Substances of Very High Concern (SVHCs) above reporting thresholds.<\/li>\n\n\n\n<li><strong>Material Declaration by Part Number:<\/strong>&nbsp;Details materials used in each component for traceability.<\/li>\n\n\n\n<li><strong>Supplier Compliance Statements:<\/strong>&nbsp;Validates supplier adherence to RoHS and REACH requirements.<\/li>\n\n\n\n<li><strong>Test Reports and Lab Evidence:<\/strong>&nbsp;Provides test results, such as XRF screening, to verify restricted substances are within limits.<\/li>\n\n\n\n<li><strong>Exemption Justification Records:<\/strong>&nbsp;Documents any exemptions claimed, including valid expiry dates.<\/li>\n\n\n\n<li><strong>SCIP Dossier (if applicable):<\/strong>&nbsp;Substances in Articles (SCIP) database reporting for products containing restricted SVHCs.<\/li>\n\n\n\n<li><strong>Technical File and Revision History:<\/strong>&nbsp;Contains detailed product data, design changes, and compliance updates.<\/li>\n\n\n\n<li><strong>Product Change Control Records:<\/strong>&nbsp;Tracks modifications that could impact compliance status.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Maintaining these documents helps ensure smooth market access and demonstrates compliance to authorities and customers. For detailed guidance on compliance documentation, visit&nbsp;<a href=\"https:\/\/www.hiitiosemi.com\/blog\/power-modules-for-commercial-hvac-and-chiller-systems-key-specs-and-selection-tips\/\">Power Modules for Commercial HVAC and Chiller Systems<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">RoHS and REACH Compliance for Power Semiconductor Exports<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Do all power semiconductor products need RoHS and REACH compliance?<\/strong><br>In practice,\u00a0most power semiconductor exports to the EU need both RoHS compliance for electronics exports and REACH compliance for semiconductors. I treat this as a basic market access check, especially for power module compliance and other electronic component compliance documents.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Does RoHS compliance guarantee REACH compliance?<\/strong><br>No.\u00a0RoHS focuses on restricted substances in electronics, while REACH covers broader chemical obligations, including\u00a0SVHC Candidate List\u00a0disclosure and\u00a0Annex XVII restrictions. A product can pass RoHS and still need separate REACH compliance for semiconductors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What happens if a product contains a restricted substance?<\/strong><br>The response depends on the substance, its level, and how the part is classified. I usually verify the\u00a0bill of materials, supplier data, and test results before making any compliance statement. In some cases, exemptions or additional documentation may apply.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>How often should compliance declarations be updated?<\/strong><br>I recommend updating them whenever there is a material change, supplier change, process change, or a new regulatory update. For stable products, current declarations should still be reviewed on a regular basis so they stay aligned with\u00a0change control\u00a0and supplier traceability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Is SCIP reporting required for every exported component?<\/strong><br>No, not automatically. SCIP obligations depend on the specific article and the applicable EU rules. If a part triggers SCIP requirements, I keep the\u00a0SCIP database for electronics\u00a0records tied to the part number and revision history.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What documents do EU customers usually request first?<\/strong><br>The most common requests are the\u00a0Declaration of Conformity,\u00a0REACH SVHC declaration,\u00a0material declaration, and supporting test evidence when needed. For buyers comparing suppliers, I also point them to the typical questions listed in this guide on&nbsp;<a href=\"https:\/\/www.hiitiosemi.com\/blog\/top-10-questions-buyers-ask-before-purchasing-power-modules\/\">what buyers ask before purchasing power modules<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Typical first-request document set<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>RoHS Declaration of Conformity<\/li>\n\n\n\n<li>REACH SVHC declaration<\/li>\n\n\n\n<li>Material declaration by part number<\/li>\n\n\n\n<li>Supplier compliance declaration<\/li>\n\n\n\n<li>Test reports or lab evidence<\/li>\n\n\n\n<li>cURL Too many subrequests by single Worker invocation.
