The EU REACH Regulation (Registration, Evaluation, Authorization and Restriction of Chemicals) is the EU's core regulation governing chemical substance management. Since its implementation in 2007, it has undergone continuous iteration, aiming to protect human health and environmental safety while promoting the sustainable development of the chemical industry. The following is an in-depth analysis of its core content and latest developments:

I. Core Regulatory Framework and Implementation Mechanisms

REACH is built on the "precautionary principle" and establishes a management system covering the entire lifecycle of chemicals, comprising four core modules:

  1. Registration
    • 1-10 tonnes per year: physico-chemical properties and toxicological data must be submitted.
    • 10 tonnes or more per year: an additional Chemical Safety Report (CSR) including exposure scenarios and risk assessment is required.
    • Scope: Chemical substances manufactured or imported in quantities of 1 tonne or more per year (including substances on their own, in mixtures, or intentionally released from articles) must be registered with the European Chemicals Agency (ECHA).
    • Data Requirements: The volume of data required increases with tonnage band.
    • Joint Registration: Manufacturers and importers of the same substance must submit data jointly, following the "one substance, one registration" principle to reduce duplicate testing costs.
  2. Evaluation
    • Dossier Evaluation: ECHA verifies the completeness of registration data. In 2021, ECHA issued 240 compliance check decisions on approximately 2,500 dossiers covering 258 substances.
    • Substance Evaluation: Member States assess substance risks. In 2021, further regulatory action was initiated for 30 substances.
  3. Authorization
    • For high-risk substances (e.g., CMR, PBT, vPvB), companies must apply for authorization before use. As of 2025, the SVHC (Substances of Very High Concern) Candidate List has been updated to 250 entries, with newly added substances including reprotoxic substances and vPvB substances.
  4. Restriction
    • Conditions are set for the manufacture, use, or placing on the market of specific substances. For example, in June 2025, new restrictions were added for N,N-dimethylacetamide (DMAC) and 1-ethyl-2-pyrrolidone (NEP), requiring companies to specify worker exposure limits (DNELs) in safety data sheets and implement risk management measures.

II. Major 2025 Revisions and Industry Impact

In April 2025, the European Commission proposed the first systematic revision of the REACH Regulation in nearly 20 years, with the following key changes:

  1. Registration Validity and Data Updates
    • Registration validity is uniformly set at 10 years; registration numbers that are not updated or are non-compliant will be revoked.
    • Simplified registration for the 1-10 tonnes per year band must be upgraded to full data requirements. Polymers must first be notified and then assessed for registration necessity.
  2. Strengthened Nanomaterial Controls
    • Adopting the 2022 EU nanomaterial definition, requiring disclosure of characterization information such as particle size and surface properties, and strengthening downstream user notification obligations.
    • Traditional testing methods may not be applicable; companies must rely on alternative methods (such as computational modeling) for risk assessment.
  3. Supply Chain Digitalization and Enforcement Upgrades
    • Importers must submit Safety Data Sheets (SDS) at customs clearance; the ECHA system automatically verifies registration and authorization numbers.
    • Member States will establish unified enforcement standards; non-compliant companies may face product detention, fines, or market bans.

III. Corporate Compliance Strategies and Challenges

1. Dynamic SVHC List Tracking and Response

  • Notification Obligation: When an article contains an SVHC at a concentration above 0.1% (w/w) and the annual export volume exceeds 1 tonne, notification must be made within 6 months of the substance's inclusion on the Candidate List.
  • Supply Chain Management: Companies must establish substance composition databases to ensure downstream customers receive timely SVHC information. For example, products containing SVHCs must be notified in the SCIP database before being placed on the market.

2. Registration and Joint Submission Optimization

  • Joint Registration Consortia: A consortium of 5 or more companies can save up to 70% on testing costs. It is recommended to partner with a Lead Registrant (LR) that has comprehensive data.
  • Data Mutual Recognition: Degradability data produced by Chinese GLP laboratories may be directly referenced, reducing testing costs.

3. Nanomaterial Registration Challenges

  • Characterization and Risk Assessment: Parameters such as nanoparticle morphology and dispersibility must be clearly defined. Traditional toxicological testing may not be applicable.
  • Additional National Requirements: Countries such as France and Belgium require separate notification of nanomaterials; attention must be paid to country-specific regulations.

4. Dual Compliance Pressure: REACH and CBAM

  • Carbon-intensive products exported to the EU (e.g., steel, aluminum) must simultaneously comply with REACH chemical management requirements and the Carbon Border Adjustment Mechanism (CBAM) emissions reporting obligations. For example, starting in 2026, aluminum exporters may face a carbon cost of approximately 595 euros per tonne of product.

IV. Recommendations for Chinese Enterprises

  1. Supply Chain Due Diligence
    • Implement three-tier auditing: verify the completeness of SDS ecological information, conduct spot checks on raw material test reports, and perform on-site audits of high-risk suppliers.
    • Establish product composition tree diagrams to clarify REACH compliance responsibilities at each supplier tier.
  2. Technology Upgrades and Alternative Solutions
    • Prioritize the use of non-SVHC alternative substances, for example, avoiding electrolytes containing LiPF6 in lithium battery production.
    • Invest in low-carbon technologies to reduce CBAM costs while optimizing chemical usage to meet REACH requirements.
  3. Policy and Tool Utilization
    • Use ECHA's IUCLID 6.8 system to submit digital dossiers, avoiding rejection of PDF formats.
    • Monitor ECHA's dispute resolution mechanisms and resolve data-sharing disputes through arbitration.

V. Typical Cases and Enforcement Trends

  • Non-Compliance Case: In June 2025, a Chinese company's children's clothing product was recalled by the EU due to drawstring design failing to meet REACH restriction provisions.
  • Compliance Practice: A chemical company reduced testing costs by 60% through joint registration and adopted nano-passivation technology, improving the corrosion resistance of UPVC round bars by 27% while obtaining FDA certification for entry into the high-end market.

Conclusion

The continued escalation of REACH regulation imposes higher requirements on global supply chains. Companies must replace "passive response" with "proactive compliance," building competitiveness through technological innovation, supply chain coordination, and policy foresight. Following the implementation of the 2025 revision, compliance capability will become a core threshold for entering the EU market. Companies are advised to plan early and leverage professional institutional resources to mitigate risks.
