REACH Compliance for Paint Raw Materials: SVHCs and the Restriction List

What REACH Is and Why It Exists

REACH was enacted in 2007 with a dual mandate: to protect human health and the environment from the risks posed by chemical substances, and to enhance the competitiveness of the EU chemicals industry through transparency and a shared evidence base. Prior to REACH, the regulatory framework for industrial chemicals in Europe was fragmented across multiple directives, with the burden of proof for chemical safety falling largely on regulators rather than industry. REACH reversed this principle — under the new system, industry must demonstrate the safety of substances it places on the market, rather than authorities proving harm before action can be taken.

The paints and coatings sector is directly affected by REACH because coating formulations are complex mixtures containing tens of chemically distinct raw materials: resins, solvents, pigments, fillers, additives, and biocides. Many of these ingredient classes contain substances that are either already restricted under REACH Annex XVII, present on the SVHC Candidate List, or candidates for future Authorisation List (Annex XIV) inclusion. The ECHA Candidate List, which triggers immediate communication obligations, contained over 240 substances as of mid-2024, with new entries added in two annual updates each year. For a typical solvent-borne industrial coating formulation with fifteen to twenty-five raw material inputs, a meaningful proportion of those inputs may include substances that require active monitoring.

Scope: Who REACH Applies To and Which Roles Matter for Coatings

REACH obligations differ depending on your role in the supply chain. The regulation defines distinct obligations for manufacturers, importers, downstream users, and distributors — and most coating formulators occupy the downstream user role relative to their raw material suppliers, while simultaneously acting as formulators placing mixtures on the market. Understanding which hat you are wearing at each stage of the supply chain is essential, because obligations and available exemptions differ significantly by role.

The critical threshold for many downstream user obligations is the 0.1% w/w concentration of an SVHC in a mixture or article. Below this threshold, communication obligations are reduced, though the substance's REACH registration status must still be confirmed. Above this threshold, the SDS must flag the SVHC in Section 15, and end-user communication obligations apply. Some Annex XVII restrictions operate on different thresholds — for example, the lead restriction in decorative paints (Entry 63) specifies a mass concentration limit of 0.009%, substantially lower than the general SVHC communication trigger.

Key Requirements: What REACH Demands of Paint Formulators

For a paint or coating formulator operating as a downstream user in the EU supply chain, the core REACH obligations cluster around four operational requirements: confirming that all raw materials are validly registered under REACH; screening the formulation ingredient list against the SVHC Candidate List and Annex XVII restriction entries; maintaining compliant Safety Data Sheets for finished mixtures supplied to professional users; and communicating SVHC presence to customers and, upon request, to consumers. Each of these requires a structured, repeatable process — not a one-time check at product launch.

Registration Verification

Formulators purchasing raw materials from EU-based suppliers can verify registration status by requesting confirmation that each substance is registered under REACH at a tonnage band that covers the supplier's volume and that includes the use in question. ECHA's public database of registered substances (available via the ECHA website) allows formulators to confirm registration status independently. For raw materials imported directly from outside the EU, the formulator may itself become the importer and bear registration obligations above the one-tonne-per-year threshold. This is a particularly common compliance gap for formulators sourcing specialty pigments, rare-earth driers, or exotic functional additives from non-EU suppliers without an EU registration in place.

SVHC Candidate List Screening

Candidate List screening should be performed against the current version of the list — ideally immediately following each ECHA update in June and December each year. The screening requires cross-referencing every substance in the formulation (including substances present in raw material mixtures) against the Candidate List by CAS number or EC number. Where a Candidate List substance is identified above 0.1% in the finished formulation, the SDS (Section 15) must be updated, customer communication obligations are triggered, and the substance should be flagged in the reformulation watch-list for future risk. ECHA's SCIP database (for articles containing SVHCs) may also require notification if the coating is supplied as or applied to articles placed on the EU market.

Annex XVII Restriction Compliance

Annex XVII to REACH is the operational restriction list — it specifies substances that may not be used above defined concentrations, in defined applications, or by defined user categories. For paint formulators, the most operationally significant entries include restrictions on lead compounds in decorative paints (Entry 63, 0.009% mass concentration limit), restrictions on chromate compounds in cement and cement-containing mixtures (Entry 47, with a Cr(VI) limit in mixed or wet cement), restrictions on dimethyl fumarate (DMF) in articles (Entry 61), and ongoing additions related to specific azo colourants and CMR solvents. Annex XVII is updated by Commission Regulations as new restriction decisions are adopted — monitoring ECHA's restriction process pipeline is essential for early warning of upcoming changes that could affect raw material sourcing.

Testing and Documentation Requirements

REACH compliance for finished paint mixtures does not typically require the formulator to generate new toxicological or ecotoxicological test data — that burden falls primarily on substance registrants (raw material suppliers). However, formulators do carry important documentation obligations: they must maintain compliant Safety Data Sheets for all finished mixtures supplied to professional downstream users, hold evidence of their raw material suppliers' REACH registration status, and retain records sufficient to demonstrate that Annex XVII restrictions have been assessed for each applicable formulation.

Safety Data Sheet (SDS) Obligations

Mixtures supplied to professional users in the EU require a Safety Data Sheet in the format specified by REACH Annex II (as updated by EU Regulation 2020/878, which revised the SDS format and introduced new UFI requirements under the CLP Regulation). The SDS must be provided in the language of the member state where the mixture is supplied. Section 3 must list components that are hazardous or are SVHCs above 0.1%, including their CAS and EC numbers and concentration ranges. Section 15 must note Candidate List SVHCs present above 0.1% and applicable Annex XVII restrictions. Where a mixture contains a substance subject to an Authorisation under REACH, the authorisation number must be stated. Formulators should also ensure that the SDS format and content aligns with the current CLP hazard classification of the mixture — the SDS and label must be consistent.

Downstream User Report

If a formulator uses a raw material substance in a way not identified in the supplier's SDS (Exposure Scenarios in the Extended SDS), the formulator has options: use the Chemical Safety Report (CSR) tool for downstream users to assess their use independently, notify ECHA via a downstream user report, or switch to a supplier whose SDS covers the intended use. The downstream user report notifies ECHA of the unregistered use and triggers ECHA's ability to require the supplier to add the use to their registration. This mechanism is often overlooked by smaller formulators who may not realise that their specific application — for example, brush application of an industrial maintenance coating in confined spaces — may not be covered by the supplier's registered uses.

Step-by-Step REACH Compliance Pathway for Paint Formulators

REACH compliance for paint formulators is not a one-time certification event — it is a continuous management process tied to formulation changes, raw material changes, and ECHA regulatory updates. The following sequence provides a practical framework for establishing and maintaining a compliant posture across the product portfolio.

1. Compile the full ingredient inventory. For every product in the portfolio, identify every substance present — including substances in raw material mixtures at sub-mixture level. Obtain current SDS for all raw materials and extract CAS/EC numbers and concentration data.
2. Verify REACH registration status for each substance. Cross-reference against the ECHA registered substances database. Identify any substances without valid EU registrations and escalate to the supplier or source an alternative registered material.
3. Screen against the SVHC Candidate List. Compare the full ingredient CAS/EC number list against the current Candidate List. Flag any substances present above 0.1% w/w in the finished mixture. Update SDS Section 15 and implement customer communication protocols for flagged substances.
4. Check Annex XVII restriction entries. Review each flagged substance type (lead compounds, Cr(VI), DMF, specific azo dyes, named solvents) against the restriction entry conditions — concentration limits, use restrictions, and customer category restrictions. Confirm compliance or reformulate to remove the restricted substance or bring it below the specified limit.
5. Assess Extended SDS Exposure Scenarios. Review supplier Extended SDS documents to confirm that the formulator's intended uses are covered. Where gaps exist, initiate downstream user reports or reformulation.
6. Prepare or update compliant SDS for finished mixtures. Ensure that the SDS for each finished coating product complies with REACH Annex II (as amended by EU Reg 2020/878) and reflects the current CLP hazard classification, UFI code, and all SVHC disclosures.
7. Implement ongoing monitoring. Subscribe to ECHA update notifications. Schedule bi-annual Candidate List screenings following each ECHA update in June and December. Monitor the ECHA restriction pipeline for substances relevant to your ingredient portfolio.

Realistic Timeline and Cost Expectations

Establishing a REACH compliance programme for a paint formulator's existing product portfolio is typically a medium-complexity project — more demanding than a simple product labelling review but substantially less burdensome than a full substance registration programme. The timescale and cost depend heavily on portfolio size, the number of raw materials used, and the thoroughness of existing raw material documentation. A formulator with twenty product formulations using fifty to seventy distinct raw material inputs should budget three to six months to complete an initial compliance audit, gap assessment, and remediation if no programme exists today.

Cost categories include internal staff time for ingredient inventory compilation and documentation review (typically the largest single cost component), external regulatory consultancy if REACH expertise is not available in-house, supplier engagement costs for obtaining compliant Extended SDS and registration confirmation, and potential reformulation costs if restricted or unregistered substances are identified. Ongoing annual maintenance — bi-annual Candidate List screenings, SDS updates, and monitoring — is substantially less intensive than the initial establishment programme, and can typically be absorbed within a part-time regulatory affairs resource for small to medium-sized formulators.

One cost category often overlooked in initial budgeting is reformulation. Identifying a Candidate List substance at above 0.1% in a core product does not immediately require reformulation — communication obligations are triggered but continued use is permitted unless the substance is on Annex XIV with a sunset date already passed. However, where a restriction (Annex XVII) applies, reformulation may be mandatory, and the timeline for identifying a compliant alternative raw material, validating its performance, and re-registering the product for relevant certifications (such as architectural specification approvals or food-contact confirmations) can add six to eighteen months to the compliance timeline.

Common Mistakes Paint Formulators Make — and How to Avoid Them

The most frequently observed REACH compliance failures among paint formulators are not wilful non-compliance but structural gaps — places where the process was never designed to catch a specific obligation. Understanding the most common patterns allows formulators to close these gaps proactively rather than discovering them during a customer audit or regulatory inspection.

Failing to Screen Substances in Raw Material Mixtures

A coating formulator may request an SDS for a raw material and identify no SVHC flags — but this can be misleading if the raw material itself is a complex mixture containing multiple substances, some of which are below the 0.1% reporting threshold in the raw material's SDS but above 0.1% in the finished coating formulation when the raw material is used at high loading. Candidate List screening must be performed at the formulation level, calculating concentration contributions from all raw material inputs, not simply by reading Section 15 of each raw material SDS in isolation.

Using Outdated Candidate List Versions

A significant proportion of compliance failures in audits involve screening against a Candidate List that is six to eighteen months out of date. With twice-annual updates, a formulation screened against the June list may already have a new SVHC obligation by December. Compliance programmes that perform screening once at product launch — and not thereafter — will systematically miss newly added substances. Assign a specific date in the compliance calendar for each ECHA update cycle, and confirm the screening is performed against the published version.

Overlooking the Annex XVII Restriction on Decorative Paints Lead Content

Entry 63 of Annex XVII restricts lead compounds in decorative paints to a maximum of 0.009% by mass (90 mg/kg) — a level that may be breached by some pigment grades, drier systems containing lead naphthenate or lead octoate, or recycled raw materials with residual lead contamination. This restriction applies to decorative paints for consumer use, and the concentration limit is substantially lower than the general SVHC communication threshold. Formulators using cobalt- or manganese-based drier blends should verify that the drier blend contains no lead compounds above this threshold, particularly when sourcing from suppliers in markets where lead driers remain in use.

Assuming the Supplier's SDS Covers All Downstream Uses

Raw material suppliers register substances for their own identified uses and the foreseeable uses of their customers. The resulting Extended SDS contains Exposure Scenarios that describe the conditions of use under which the substance is considered safe. If a formulator uses the substance in conditions that differ materially from the registered Exposure Scenarios — for example, spray application in confined spaces, high-temperature application, or use by non-professional consumers — the formulator may be using the substance outside the scope of the registration. This is a genuine compliance obligation, and the mechanism to address it — downstream user reports to ECHA — is underused among smaller formulators who may not realise it applies to them.
