REACH Regulation SDS Analysis: Safety Data Sheet Compliance, SVHC Screening and Testing Services

REACH Regulation SDS analysis is a critical compliance process for manufacturers, importers, and downstream users placing chemical substances, mixtures, or articles on the European Union market. A Safety Data Sheet (SDS) prepared in accordance with Regulation (EC) No 1907/2006 (REACH) Annex II, as amended by Regulation (EU) 2020/878, communicates hazard information, safe handling practices, and regulatory status throughout the supply chain. Professional SDS analysis combines document review with laboratory testing, including SVHC screening against the ECHA Candidate List, to ensure full regulatory conformity and reduce trade risks.

Technical Overview

REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) is the European Union regulation (EC) No 1907/2006 governing the production, import, and use of chemical substances. Under Articles 31 and 32 of REACH, suppliers of substances and mixtures that meet specified criteria for physical, health, or environmental hazards must provide a Safety Data Sheet (SDS) to their downstream users and distributors. The SDS format and content are defined in Annex II of REACH, most recently amended by Regulation (EU) 2020/878, which has been mandatory since 31 December 2022.

A compliant REACH SDS consists of sixteen standardized sections covering substance identification, hazard classification under the CLP Regulation (EC) No 1272/2008, composition, first-aid measures, firefighting measures, accidental release measures, handling and storage, exposure controls, physical and chemical properties, stability and reactivity, toxicological information, ecological information, disposal considerations, transport information, regulatory information, and other relevant data. SDS analysis verifies the technical accuracy, consistency, and completeness of each section against current regulatory requirements.

A core element of REACH SDS analysis is the evaluation of Substances of Very High Concern (SVHC). The ECHA Candidate List, updated approximately twice per year, now contains more than 240 substances including phthalates, brominated flame retardants, perfluorinated compounds, PAHs, and various inorganic substances. Any SVHC present in an article above 0.1% weight-by-weight (w/w) triggers Article 33 communication duties, and concentrations above 0.1% w/w in articles may also impose notification obligations under Article 7(2). For substances and mixtures, SVHC content at or above 0.1% w/w must be disclosed in Section 3 of the SDS. Registered substances requiring a Chemical Safety Report must also generate an Extended Safety Data Sheet (eSDS) incorporating exposure scenarios in Section 1.

Professional SDS analysis services provide a comprehensive compliance pathway: document gap assessment against Annex II requirements, hazard classification review under CLP, laboratory verification of substance composition, SVHC and restricted substance screening, and remediation of identified deficiencies by competent personnel as required by Article 31(6).

Testing Items

REACH SDS analysis encompasses both document assessment and laboratory verification. Typical testing programs include:

• SVHC Candidate List screening covering all listed substances, including phthalates (DEHP, DBP, BBP, DINCH-related impurities), bisphenols, per- and polyfluoroalkyl substances (PFAS), PAHs, siloxanes (D4, D5, D6), and metals compounds.
• Annex XVII restricted substance verification, including cadmium, lead, nickel release, hexavalent chromium, organotin compounds, and specific substance-group limits.
• Physical-chemical property determination for SDS Section 9: appearance, odor, pH, melting point, boiling point, flash point, flammability, vapor pressure, density, water solubility, partition coefficient (n-octanol/water), auto-ignition temperature, viscosity, and oxidizing properties.
• Classification data verification under CLP: acute toxicity estimates, skin and eye irritation, sensitization, germ cell mutagenicity, carcinogenicity, reproductive toxicity, and STOT endpoints.
• Environmental endpoint review: aquatic toxicity, biodegradability, bioaccumulation potential, and PBT/vPvB assessment relevant to SDS Section 12.
• Document conformity review: sixteen-section completeness, P-number and revision date logic, Section 1 to Section 3 consistency, exposure scenario attachment for eSDS, and mandatory statement of the nanoform-specific information where applicable.

Testing Methods

Analytical testing for REACH SDS compliance relies on internationally recognized methods, typically aligned with EN, ISO, and EPA standards:

• Gas Chromatography-Mass Spectrometry (GC-MS) with solvent extraction or thermal desorption for phthalates, PAHs, VOCs, and siloxanes.
• High Performance Liquid Chromatography (HPLC) and LC-MS/MS for bisphenols, perfluorinated compounds, azo dye precursors, and thermally labile substances.
• Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) and ICP-Mass Spectrometry (ICP-MS) following acid digestion for antimony, arsenic, cadmium, lead, cobalt, and other metallic SVHC and restricted elements.
• X-ray Fluorescence Spectrometry (XRF) as a rapid screening technique for elemental composition and metals prioritization in articles and polymers.
• Ion Chromatography (IC) for chromate (Cr VI) speciation and ionic species determination.
• Closed cup and open cup flash point testing (Pensky-Martens, Abel, Tag methods) for flammable liquid classification.
• OECD Guideline methods for physical-chemical properties, including OECD 102 (melting point), OECD 103 (boiling point), OECD 105 (water solubility), OECD 107 and 117 (partition coefficient), and OECD 122 (pH).
• Colorimetric and spectrophotometric screening for organotin compounds and formaldehyde release.

Method selection follows a weight-of-evidence approach: XRF screening identifies elements of concern, followed by confirmatory wet-chemical analysis with matrix-matched calibration, full method blanks, spike recoveries, and measurement uncertainty reported against the 0.1% w/w regulatory threshold.

Applications

REACH SDS analysis supports compliance across diverse industry and trade scenarios:

• Export compliance for manufacturers shipping chemical substances, mixtures, or articles into the EU, EEA, and Northern Ireland markets, ensuring customs and enforcement authority acceptance.
• Supplier SDS review and verification by downstream users who must confirm that received documentation meets Annex II requirements before placing products on the market.
• Only Representative coordination for non-EU manufacturers supporting registration dossiers and downstream SDS communication.
• Product development and reformulation support, enabling substitution of SVHC and restricted substances with safer alternatives in line with ECHA substitution strategy.
• Risk management implementation, using verified SDS data to establish workplace exposure controls, personal protective equipment programs, and emergency response procedures.
• Due diligence and supply chain audits for retailers, brands, and importers responding to customer declarations, ECHA enforcement campaigns (such as REF projects), and market surveillance actions.
• Mergers, acquisitions, and portfolio reviews where the regulatory status of chemical inventories must be quantified and documented.
• Training and internal compliance program development for hazard communication responsibilities under Articles 31 through 36.

FAQ

When is a Safety Data Sheet required under REACH?

An SDS must be supplied when a substance or mixture meets criteria for classification as hazardous under CLP, when a substance is persistent, bioaccumulative and toxic (PBT) or very persistent and very bioaccumulative (vPvB), or when it appears on the Candidate List for reasons other than the above thresholds. An SDS may also be supplied voluntarily upon downstream user request under Article 32 communication duties.

Who is authorized to prepare a REACH SDS?

Article 31(6) requires that the SDS be compiled by a competent person, meaning an individual with appropriate training and practical experience in the relevant fields, including toxicology, chemistry, occupational health, and regulatory affairs. Third-party laboratories and consultancies routinely provide this competency for exporters without EU-based regulatory teams.

What is the difference between an SDS and an Extended SDS?

An Extended Safety Data Sheet (eSDS) includes exposure scenarios derived from the Chemical Safety Report as an annex, required when the substance is subject to registration and requires a chemical safety assessment. The exposure scenarios must be referenced in Section 1 of the SDS.

How often must an SDS be updated?

The SDS must be updated without delay when new hazard information becomes available, when an SVHC is added to the Candidate List affecting the product, or when the classification or use restrictions change. The updated version must be supplied to all recipients who received the product within the preceding twelve months, and the revision date in Section 16 must reflect each change.

What triggers SVHC testing and communication for articles?

If an SVHC is present in an article above 0.1% w/w, the supplier must provide sufficient information to allow safe use, including the substance name where requested by a consumer under Article 33. Notification to ECHA under Article 7(2) is additionally required when the substance is present above one tonne per year per producer or importer and exposure cannot be excluded, unless the use is registered or an exemption applies.

In what languages must the SDS be provided?

The SDS must be supplied in an official language of each Member State where the substance or mixture is placed on the market, unless the competent authority has agreed that another language is acceptable. Professional SDS services therefore provide multilingual compilation aligned with target market requirements.

How long does REACH SDS analysis take?

Document review is typically completed within three to five working days, while laboratory SVHC screening programs require approximately seven to fifteen working days depending on sample matrix complexity, the number of substances requested, and whether confirmatory quantification is needed following initial screening.

What is the difference between MSDS and SDS?

MSDS (Material Safety Data Sheet) is the legacy terminology associated with earlier national and pre-GHS systems. SDS under REACH Annex II follows the sixteen-section GHS-aligned format with EU-specific requirements, and the term SDS is the legally correct designation in the EU regulatory framework.
