Safety Data Sheet (SDS) Translation Services

Do safety data sheets have to be in English, or are other languages required?

Safety Data Sheets do not have to be only in English: REACH Article 31(5) requires an SDS in the official language(s) of every EU Member State where the substance or mixture is placed on the market. Beyond the EU, the UK, US, Canada and Asia-Pacific markets each impose their own language obligations, meaning that a single product sold across multiple jurisdictions will typically require a suite of localised SDS versions. The language requirement is triggered at the point of market placement — the obligation falls on the manufacturer, importer or distributor responsible for putting the product on sale in that territory.

What does REACH Article 31 require for SDS language?

REACH Article 31(5), part of REACH Regulation (EC) 1907/2006, requires that a Safety Data Sheet is supplied free of charge in an official language of each EU Member State where the substance or mixture is placed on the market, unless that Member State provides otherwise. See our REACH Compliance Translation service for the full obligation set. The rule applies equally to the original manufacturer and to any importer or distributor placing the chemical on a local EU market. Failure to supply a compliant, locally-language SDS before or at the point of first delivery constitutes a breach of REACH and can trigger enforcement action by the relevant national authority.

Which EU languages are triggered by placing a chemical on the EU market?

There are 24 EU official languages triggered by REACH Article 31. Because the obligation is market-specific rather than country-specific, some languages serve more than one Member State — German, for example, is required for Germany, Austria and Luxembourg. The table below lists all 24 languages and their primary markets.

Spain adds a further layer: regional language legislation imposes multilingual obligations covering Catalan, Basque, Galician, Valencian and Aranese for products and services delivered in those regions, with full compliance required by 28 December 2026.

What are the SDS language rules in the UK, US, Canada and Asia-Pacific?

SDS language rules differ significantly by market. Following Brexit, the UK operates its own regulatory framework — UK REACH (2020) — under which an SDS placed on the GB market must be supplied in English, with Welsh carrying optional status. In the United States, OSHA HCS 2012 (29 CFR 1910.1200) requires the SDS to be in English; employers bear a separate obligation to ensure worker comprehension, which in practice drives strong demand for Spanish-language SDS versions. Canada’s WHMIS 2015 framework goes further, mandating full bilingual provision in both English and French. The comparative table below summarises the key requirement per jurisdiction.

What is the difference between an SDS and an MSDS?

The difference between an SDS and an MSDS is standardisation: ‘MSDS’ is the pre-2012 US term for a document with no fixed layout, while ‘SDS’ is the current 16-section format harmonised under the UN Globally Harmonized System of Classification and Labelling of Chemicals (GHS). The two terms refer to the same category of hazard communication document, but the SDS format is rigorously structured in a way its predecessor was not. The GHS harmonisation that replaced ‘MSDS’ with ‘SDS’ was a deliberate effort to eliminate the inconsistency that arose when manufacturers applied different layouts, section orders and terminology to what was nominally the same document type.

The UN adopted the Globally Harmonized System of Classification and Labelling of Chemicals in 2003, providing a shared 16-section SDS format intended to work across jurisdictions. OSHA aligned the US Hazard Communication Standard with GHS in 2012, at which point the term ‘MSDS’ was officially replaced with ‘SDS’ in US regulatory language. The 16-section format has since been adopted by REACH Annex II (EU), WHMIS 2015 (Canada) and JIS Z 7253 (Japan), making it the de facto global standard for chemical hazard communication.

When is ‘MSDS’ still the correct term?

The term MSDS remains in informal use in US industry and in legacy document archives for chemicals that were classified before OSHA’s 2012 HazCom alignment. However, every SDS placed on the market today under any GHS-aligned jurisdiction must follow the 16-section SDS format — the older variable-layout MSDS is not accepted as compliant. When commissioning translation of an older MSDS-format document, a professional SDS translation service will first assess whether the source document needs reformatting and content updating to meet the 16-section structure before translation proceeds. Translating a non-compliant source document produces a non-compliant translated document, regardless of linguistic accuracy.

Why is accurate SDS translation important for global compliance?

What are the challenges in translating SDS documents?

SDS translation is one of the most technically demanding forms of regulated document translation because it combines deep chemical and toxicological knowledge with jurisdiction-specific regulatory expertise across multiple parallel legal frameworks. A qualified SDS translator must understand not only the language of the target market but also how GHS classification maps — or fails to map — onto the specific regulatory implementation in that country. There are five core challenges that distinguish SDS translation from general technical translation.

1. Hazard vocabulary precision: The UN GHS provides the overarching system of classification and labelling of chemicals, but each jurisdiction’s implementation introduces local terminology, signal words and statement codes that must be applied exactly as published. H- and P-statement libraries are available in 24 EU languages and must be reused verbatim — any paraphrase, however linguistically accurate, constitutes non-compliance.
2. Divergent national exposure limits: Occupational exposure limits (WEL in the UK, PEL in the US, MAK in Germany) are set independently by national authorities and are not interchangeable. Section 8 of every translated SDS requires the source values to be replaced with the values applicable in the target jurisdiction, not merely converted or translated.
3. Legal defensibility: The translated SDS is a legally binding document in the target market. Every regulatory citation in Section 15, every transport code in Section 14 and every classification statement in Section 2 must be verifiable against the applicable national regulation. A translation that is linguistically fluent but regulatorily incorrect exposes the responsible party to enforcement action.
4. Version synchronisation across languages: A product sold in multiple markets requires parallel SDS versions in each required language. When the source SDS is revised — following a classification update, a new component disclosure or a change in supplier details — every translated version must be updated simultaneously. Without a disciplined version-control process, language versions diverge and the older versions become non-compliant.
5. Format and file complexity: Source SDS documents arrive in a wide range of formats — structured XML from SDS authoring platforms, complex PDF layouts and legacy Word files — each with its own formatting challenges. Preserving the 16-section structure, table layouts, pictogram placement and regulatory formatting conventions through the translation workflow requires specialist desktop publishing capability alongside linguistic expertise.

How are linguistic and cultural nuances handled in chemical SDS?

Linguistic and cultural nuances in chemical SDS are handled by native-speaker translators who hold recognised chemistry or regulatory qualifications. They normalise units to the local measurement system, adapt first-aid instructions to the conventions of the target country’s emergency services, and localise addresses, telephone number formats and regulatory authority names. Cultural adaptation extends to PPE descriptions, where the visual conventions and terminology used in safety signage vary between markets and must reflect what workers in that country actually recognise and use.
