Understanding the REACH Annex XVII CMR Update
The REACH Annex XVII CMR substances update represents the European Commission's ongoing effort to protect public health by restricting consumer access to substances classified as carcinogenic, mutagenic, or toxic for reproduction. This omnibus technical update aligns Entries 28, 29, and 30 with the latest hazard classifications established under the 21st and 22nd Adaptation to Technical Progress to the CLP Regulation.
The European Commission REACH Restricted Substances page provides authoritative guidance on Annex XVII requirements. CMR chemical restrictions EU regulations specifically target substances that pose the most serious health hazards, prohibiting their sale to general consumers while allowing continued professional and industrial use under controlled conditions.
REACH CMR substances compliance 2026 requires understanding that these restrictions apply to substances, constituents of other substances, and mixtures. Manufacturers cannot circumvent requirements by incorporating restricted substances into formulations. The regulation captures both pure substances and any mixture containing restricted chemicals above specified concentration thresholds.
The primary objective extends beyond simple prohibition. By restricting consumer access while permitting professional use, the regulation acknowledges that some CMR substances serve essential industrial functions while recognizing that general consumers lack the training, equipment, and procedures necessary for safe handling.

Key Timeline and Adoption Process
The January 9, 2026 draft release initiates a regulatory process that will culminate in legally binding restrictions. Organizations must understand this timeline to prepare compliance activities appropriately.
January 9, 2026: Draft Proposal Release
The European Commission published the draft technical update, making the proposed substance additions publicly available for stakeholder review. This date marks the beginning of formal regulatory proceedings that will establish enforceable compliance obligations.
Feedback Period: Early 2026
Following the draft release, stakeholders may submit comments through the European Commission Better Regulation Portal. This feedback period allows industry participants to raise technical concerns, implementation challenges, or alternative approaches before final adoption.
Parliamentary and Council Scrutiny: Mid-2026
Based on currently available regulatory guidance, the proposal will undergo review by the European Parliament and Council following the feedback period. This scrutiny process may result in modifications before final adoption.
Final Adoption and Publication: Later 2026
Final adoption and publication in the Official Journal of the EU are anticipated later in 2026. The effective date for compliance will be established in the published regulation, typically providing a transition period for market adjustment.
Proactive compliance risk management enables organizations to begin preparation now rather than waiting for final publication. Early reformulation and supply chain adjustments prevent last-minute scrambles that compromise product quality and market continuity.

Concentration Limits and Classification Categories
REACH CMR substances compliance 2026 requires understanding the concentration thresholds that trigger restriction applicability. Different CMR classifications carry different limits reflecting hazard severity.
Category 1A and 1B Carcinogenic Substances: 1,000 ppm
Substances classified as Carcinogenic Category 1A (known human carcinogens) and Category 1B (presumed human carcinogens) face the most stringent concentration limit. Products containing these substances at or above 0.1% by weight cannot be sold to general consumers.
Fluoroethylene's Category 1A classification reflects confirmed human carcinogenicity, while substances like Multi-walled carbon nanotubes and Barium chromate carry Category 1B classifications based on presumed carcinogenic potential from animal studies and mechanistic evidence.
Mutagenic Substances: 1,000 ppm
Substances classified as Mutagenic Category 1B face equivalent concentration restrictions. N,N'-Methylenediacrylamide exemplifies this category, with chemical reformulation requirements affecting adhesive and polymer applications where this substance provides crosslinking functionality.
Reproductive Toxicity Substances: 3,000 ppm
Substances classified as Toxic for Reproduction Category 1B face a slightly higher concentration threshold of 0.3% by weight. This category includes the largest number of newly restricted substances, affecting diverse applications from cleaning products (sodium perborate) to industrial processing aids.
The differential thresholds reflect risk assessment approaches that consider both hazard severity and typical exposure scenarios. However, organizations should note that even the 3,000 ppm threshold represents a relatively low concentration that many commercial formulations may exceed. **Restricted substance list compliance** requires systematic portfolio screening rather than assumptions about formulation safety.
Industries Facing Direct Compliance Impact
The REACH Annex XVII CMR update creates varying compliance obligations across industries based on substance usage patterns and market channels. Executive leadership should evaluate organizational exposure within the following sector categories.
Chemicals and Plastics
Chemical manufacturers and formulators face the most direct REACH CMR substances compliance 2026 obligations. Organizations producing raw materials containing listed substances must evaluate whether products are sold to general consumers or restricted to professional users. Automated regulatory monitoring CMR capabilities enable tracking across extensive product catalogs.
Trimethyl phosphate's multi-appendix listing affects flame retardant formulations, plasticizer applications, and chemical synthesis intermediates. Organizations must trace this substance through supply chains to identify all affected products.
Consumer Goods
Producers of DIY products, adhesives, and coatings face immediate reformulation pressure. Consumer-grade products containing restricted substances above concentration limits must either be reformulated or withdrawn from retail channels. Building future-ready compliance infrastructure enables systematic product portfolio assessment.
The nitrous oxide restriction particularly affects consumer aerosol products where this propellant serves functional purposes. Chemical reformulation requirements may necessitate packaging redesign alongside formulation changes.
Cosmetics and Personal Care
Cosmetics manufacturers must evaluate ingredient lists for potential CMR overlaps. While many substances on this list have limited cosmetics applications, comprehensive screening ensures no restricted substances appear in consumer-facing products. Global cosmetics industry regulatory shifts continue reshaping formulation requirements beyond CMR restrictions.
Textiles and Apparel
Textile manufacturers face restricted substance list compliance obligations affecting processing chemicals, finishing agents, and dyes. Carcinogenic substances compliance requires screening textile processing inputs against the newly restricted list. Compliance and regulation managers should coordinate with supply chain partners to verify compliance throughout production chains.
Retail
General retailers selling chemical mixtures to the public face market access restrictions for affected products. Retail compliance requires supplier verification ensuring that consumer-grade products meet CMR restrictions. Effective supplier collaboration enables retailers to maintain compliant product assortments.

Labelling and Market Restrictions
REACH CMR substances compliance 2026 imposes specific labelling requirements for products that remain available to professional users. Organizations must implement these requirements alongside market channel restrictions.
Professional Use Labelling Requirement
Packaging of substances and mixtures containing restricted CMR substances must be marked visibly, legibly, and indelibly with the statement: "Restricted to professional users."
This labelling requirement applies when products contain restricted substances at or above concentration limits but are legitimately supplied to professional users rather than general consumers. The label serves both regulatory compliance and practical functions, alerting handlers to restricted status and preventing inadvertent consumer sale.
Market Channel Restrictions
The restriction prohibits placing listed substances on the market for supply to the general public when concentrations meet or exceed specified limits. This prohibition encompasses:
Direct consumer sales through retail channels
Online sales to non-professional purchasers
Distribution through channels that cannot verify professional user status
Organizations must implement market channel controls ensuring restricted products reach only qualified professional users. AI compliance software chemicals capabilities help track product distribution and flag potential channel violations.
Compliance Duty for Manufacturers
Manufacturers must review product portfolios against newly added CAS/EC numbers to ensure consumer-grade products are reformulated or withdrawn from public markets before the effective date. This compliance duty requires:
Comprehensive ingredient and formulation review
Concentration testing where composition uncertainty exists
Reformulation planning for affected consumer products
Market withdrawal procedures for non-reformulatable products
Labelling updates for professional-use products
Streamlined supplier documentation processes ensure raw material suppliers provide accurate composition data supporting compliance assessments.
Business and Supply Chain Implications
REACH CMR substances compliance 2026 creates business consequences extending beyond direct regulatory obligations. Organizations must understand these implications to secure executive support for compliance investments.
Product Reformulation Costs
Products requiring reformulation to eliminate restricted substances incur development costs, testing expenses, and potential performance compromises. Early identification of affected products enables reformulation planning that maintains product quality while achieving compliance.
Chemical reformulation requirements vary significantly by substance and application. Some restricted substances have readily available alternatives, while others serve unique functions requiring extensive development to replace. **Procurement and supply chain leaders** should evaluate alternative material availability early in compliance planning.
Market Access Implications
Products failing to meet CMR restrictions face EU market exclusion for consumer sales. Organizations must decide whether to reformulate for continued consumer market access, transition to professional-only distribution, or withdraw products entirely.
Supply Chain Verification
CMR chemical restrictions EU regulations require supply chain transparency that many organizations lack. Manufacturers must verify that raw materials and components do not contain restricted substances above concentration limits. This verification requires supplier engagement and potentially third-party testing where supplier data proves insufficient.
Replacing spreadsheets with scalable systems enables systematic supply chain compliance management across multiple suppliers and materials.
Competitive Positioning
Early compliance achievement creates competitive advantages as restrictions take effect. Organizations demonstrating REACH CMR substances compliance 2026 readiness can assure customers of continued supply while competitors struggle with reformulation delays.
Strategic Preparation Checklist
Organizations should implement systematic preparation activities to achieve REACH CMR substances compliance 2026 before final adoption. The following checklist provides framework for compliance program development.
Portfolio Assessment
Screen all product formulations against the 22 newly restricted substances
Identify products sold to general consumers versus professional users
Prioritize affected products by revenue exposure and reformulation complexity
Document current concentrations where composition data exists
Supply Chain Verification
Request material declarations from suppliers covering restricted substances
Identify supply chain exposure to newly restricted CAS/EC numbers
Qualify alternative suppliers for substances requiring replacement
