UK REACH Candidate List 2026: 15 New SVHCs, SDS Updates, Article Notifications & Compliance Guide

UK REACH SVHC Update 2026: What Manufacturers, Importers, Distributors and Article Suppliers Need to Know

For several years, the UK REACH Candidate List of Substances of Very High Concern (SVHCs) remained largely unchanged following the UK's departure from the European Union. During the same period, the EU REACH Candidate List continued to expand as new substances were identified as SVHCs.

This created a compliance gap for businesses operating across both markets.

Many companies therefore continued to rely on existing EU REACH compliance assessments and assumed that their UK REACH substance inventory would remain relatively stable.

That situation has now changed.

On 15 June 2026, the UK Health and Safety Executive (HSE) added 15 new substances and substance groups to the UK REACH Candidate List. The update represents the first major expansion of the UK Candidate List since UK REACH came into operation and signals a new strategic direction toward closer alignment with the EU approach.

Development is particularly important for businesses manufacturing, importing, distributing or supplying chemicals, mixtures, components and articles in Great Britain.

At the same time, the UK Government has confirmed a new strategic approach under which future UK REACH Candidate List development is expected to become more closely aligned with international partners, particularly the EU.

What Is the UK REACH Candidate List?

The UK REACH Candidate List identifies substances that have been formally recognized as Substances of Very High Concern (SVHCs) under Article 59 of UK REACH.

SVHC identification can be based on hazardous properties including:

• Carcinogenic, mutagenic or toxic for reproduction (CMR) properties
• Persistent, bioaccumulative and toxic (PBT) properties
• Very persistent and very bioaccumulative (vPvB) properties
• Other substances giving rise to an equivalent level of concern, including certain substances with endocrine-disrupting properties

Once a substance is formally included on the UK Candidate List, specific regulatory obligations can apply to suppliers of substances, mixtures and articles.

The Candidate List is therefore much more than a reference database. It is an important trigger for chemical compliance, supply-chain communication, SDS management, article assessment and future authorization planning.

What Changed on 15 June 2026?

HSE formally added 15 SVHC substances or substance groups to the UK REACH Candidate List following a public consultation launched in March 2026. The consultation closed on 20 April 2026 before HSE completed its assessment and confirmed the additions.

The new entries include substances associated with applications such as flame retardants, photo initiators, antioxidants, solvents, dyes, cross-linking agents, polyurethane-related applications and specialty chemicals.

15 New UK REACH SVHC Entries

These substances were previously evaluated through the UK SVHC identification process, with HSE publishing proposals and allowing stakeholders to provide scientific, technical and use-related information before formal inclusion.

Why Is the 2026 UK REACH SVHC Update Important?

The significance of this update extends beyond the addition of 15 substances.

The UK Government's February 2026 policy statement established a new strategic approach to the Candidate List. The previous interim principles introduced after the UK's exit from the EU were withdrawn, with the Government stating that the new approach should enable protections to be introduced more quickly and, in a manner, more aligned with key trading partners, particularly the EU.

This means businesses should no longer treat the UK REACH Candidate List as a static inventory.

Instead, companies should establish a continuous UK REACH SVHC monitoring process.

EU REACH and UK REACH Are Still Separate

Closer alignment does not mean that UK REACH and EU REACH have become one regulatory system.

Businesses must continue to distinguish between:

• UK REACH for Great Britain
• EU REACH for the European Union
• Separate regulatory responsibilities applicable in Northern Ireland

Therefore, companies selling products in both jurisdictions should maintain separate regulatory assessments, even where the Candidate Lists increasingly overlap.

Which Businesses Could Be Affected?

The update may affect a wide range of industries, including:

• Chemical manufacturers and importers
• Plastics and polymer manufacturers
• Electronic and electrical equipment manufacturers
• Automotive manufacturers and suppliers
• Textile and footwear companies
• Furniture manufacturers
• Coating and ink manufacturers
• Adhesive and sealant manufacturers
• Consumer product manufacturers
• Packaging suppliers
• Medical and industrial equipment manufacturers
• Distributors and downstream users

The greatest compliance risk may not always be associated with the finished product itself.

SVHCs can be present in individual components, coatings, polymers, adhesives, inks, flame-retardant systems, additives or other materials used within a finished article.

The 0.1% SVHC Threshold: Why It Matters

One of the most important values in UK REACH SVHC compliance is the 0.1% weight-by-weight (w/w) concentration threshold.

Businesses should evaluate whether an SVHC is present at or above this concentration in relevant articles or mixtures and determine which obligations apply.

For articles, UK REACH Article 7(2) requires producers and importers to notify HSE where:

1. The SVHC is present above 0.1% w/w, and
2. The total quantity of that substance in the relevant articles exceeds 1 tonne per producer or importer per year.

Where applicable, notification must generally be made within six months of the substance's inclusion on the Candidate List.

This makes the 15 June 2026 update particularly important for companies that manufacture or import large volumes of articles containing newly listed substances.

Key UK REACH Compliance Actions for Businesses

1. Conduct a UK REACH SVHC Portfolio Screening

The first step should be a structured SVHC impact assessment across the entire product portfolio.

Review:

• Product formulations
• Raw materials
• Components
• Articles
• Packaging
• Coatings
• Adhesives
• Additives
• Masterbatches
• Supplier declarations
• Bills of materials (BOMs)

Do not rely exclusively on historical EU REACH assessments.

2. Review Safety Data Sheets (SDSs)

Businesses should review their SDS inventory to determine whether the newly listed SVHCs affect existing hazard communication obligations.

For relevant mixtures, Candidate List inclusion can trigger the need to reassess SDS information, particularly where a non-classified mixture contains a Candidate List substance at or above the applicable concentration threshold under UK REACH.

An SDS review should therefore include:

• Section 3 – Composition/information on ingredients
• Section 8 – Exposure controls/personal protection
• Section 11 – Toxicological information
• Section 12 – Ecological information
• Section 15 – Regulatory information

Where required, SDSs should be updated and communicated through the supply chain.

3. Assess Articles and Components

Article suppliers should determine whether any newly listed SVHC is present above 0.1% w/w.

This assessment should extend beyond finished goods to individual components.

For example:

Finished Product → Component → Material → Substance → SVHC Status

This product-to-substance mapping approach helps identify hidden SVHC exposure that may not be visible from a finished-product formulation alone.

4. Review of Supplier Compliance Data

Supplier information is a critical part of the UK REACH compliance process.

Companies should request updated information regarding:

• SVHC presence
• Substance concentration
• Material Composition
• Article-level declarations
• Recent formulation changes
• Updated SDSs
• Regulatory declarations
• Testing data where appropriate

Supplier declarations should also be periodically refreshed rather than treated as permanently valid.

5. Evaluate Article Communication Obligations

Under UK REACH Article 33, suppliers of articles containing a Candidate List substance above 0.1% w/w must provide sufficient information to allow safe use of the article, including at least the name of the substance.

Consumers also have rights to request information about relevant SVHC content.

This makes accurate article-level substance information essential for both regulatory compliance and customer communication.

UK REACH 2026 Compliance Checklist

UK REACH vs EU REACH: What Businesses Should Understand

For companies operating in both markets, one of the biggest compliance mistakes is assuming that an EU REACH assessment automatically establishes UK REACH compliance.

The two systems remain legally distinct.

However, the UK's new strategic direction means that EU REACH developments can become valuable early-warning signals for UK businesses.

A practical compliance model is therefore:

EU REACH Monitoring → UK Regulatory Watch → UK Candidate List Assessment → Product Screening → Compliance Action

This approach allows companies to begin reviewing potentially affected materials before a substance becomes an immediate UK compliance issue.

Common UK REACH SVHC Compliance Challenges

Businesses frequently encounter the following issues:

1. Incomplete Substance Data

Suppliers may provide generic declarations without sufficient information about individual substances or concentrations.

2. Complex Article Supply Chains

Multi-component products can make it difficult to determine where an SVHC is located and whether the 0.1% threshold is exceeded.

3. Outdated SDSs

Historical SDS versions may not reflect the latest Candidate List status or current product composition.

4. EU-Only Compliance Systems

Companies that previously relied on EU REACH monitoring may not have independent UK regulatory workflows.

5. Poor Change Management

A formulation or supplier change can alter SVHC status without triggering an internal compliance review.

How Businesses Can Prepare for Future UK REACH Updates

The June 2026 update should be viewed as the beginning of a more active UK REACH Candidate List cycle rather than a one-time event.

Businesses should be established:

• Continuous UK REACH Candidate List monitoring
• EU REACH and UK REACH regulatory tracking
• Centralized substance inventories
• Product-to-substance mapping
• Supplier compliance questionnaires
• SDS review procedures
• Article SVHC assessments
• Regulatory change-management procedures
• Periodic portfolio reassessments
• Documented compliance evidence

HSE has already indicated that additional Candidate List consultations will form part of the future UK REACH process, making ongoing regulatory monitoring increasing important.

Why Act Now?

The consequences of missing a Candidate List update can extend beyond regulatory non-compliance.

Potential business impacts include:

• Customer compliance requests
• Delayed product shipments
• Supplier remediation
• SDS revisions
• Product reformulation
• Additional testing
• Supply-chain disruption
• Increased administrative costs
• Potential authorization or substitution pressure

Early identification gives companies more time to evaluate alternatives and implement corrective actions before regulatory or commercial pressure increases.

Conclusion

The 15 June 2026 UK REACH Candidate List update represents an important turning point for UK chemical regulatory compliance.

The addition of 15 new SVHC substances demonstrates that businesses can no longer assume that the UK Candidate List will remain unchanged. The UK's new strategic approach also points toward a more active and increasingly aligned system for identifying substances of very high concern.

For manufacturers, importers, distributors and article suppliers, the priority should be to screen products, review formulations and components, update SDSs where necessary, assess the 0.1% threshold, evaluate Article 7 and Article 33 obligations, and strengthen supplier data management.

Companies selling into both Great Britain and the EU should continue to manage UK REACH and EU REACH independently while using EU regulatory developments as an important forward-looking compliance signal.

Proactive UK REACH SVHC management is no longer optional, it is an essential part of effective chemical regulatory compliance.
