To place a CE-marked product on the EU market, you must translate the instructions for use, safety information, and the EU Declaration of Conformity into the official language of every member state where the product is sold, across as many of the 24 official EU languages as your markets require. Bluente is an AI-powered document translation platform used by 30,000+ professionals to translate files in 120+ languages while preserving the original formatting, so a technical manual, a label, or a Declaration of Conformity comes back in each target language with its tables, warnings, and clause numbering exactly intact.
This is a compliance requirement, not a nicety. A missing or inaccurate translation can hold up market entry or trigger enforcement action, and the bar rises again on 20 January 2027 when EU Machinery Regulation 2023/1230 fully replaces Directive 2006/42/EC. This guide explains what must be translated, into which languages, and how to do it without breaking the documents.
What CE Marking Documents Must Be Translated?
The documents that must be translated for CE marking are the instructions for use and assembly, the safety and warning information, and the EU Declaration of Conformity, each into the official language or languages of the member state where the product is placed on the market. Technical documentation is generally kept in one working language, often English, but enforcement authorities can require specific parts in the local language during a check.
The distinction matters for scope. Anything a user or installer relies on to operate the product safely must be in their language, so a machine sold into Germany, France, Spain, and Italy needs that user-facing content in German, French, Spanish, and Italian. The internal technical file can stay in your working language, but you should be ready to produce local-language summaries on request.
Which Languages Do You Actually Need?
You need the official languages of each EU member state where you sell the product, drawn from the 24 official EU languages: Bulgarian, Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, German, Greek, Hungarian, Irish, Italian, Latvian, Lithuanian, Maltese, Polish, Portuguese, Romanian, Slovak, Slovenian, Spanish, and Swedish. The exact set depends on your distribution footprint, not on a single EU-wide default.
A manufacturer selling across a dozen markets can therefore need a dozen language versions of the same manual and Declaration of Conformity, each kept in sync as the product changes. Managing that by sending files to an agency per language is slow and expensive; Bluente translates all of them from one source in minutes and keeps terminology locked across every version with a custom glossary.
How Do You Keep the Declaration of Conformity Formatting Intact?
You keep the Declaration of Conformity intact by translating it with a layout-aware engine that preserves its structure, the product identifiers, the list of directives and harmonized standards, the signatory block, so only the language changes. A DoC is a structured legal attestation, and a translation that reflows its fields or drops a standard reference undermines the document.
The same is true of technical manuals, which are dense with tables, numbered warnings, pictograms, and cross-references. General-purpose tools strip this structure or leave text that is embedded in images, such as labels on a diagram, untranslated. Bluente preserves the layout and uses OCR to translate text inside images and charts, so a warning baked into a figure is translated rather than skipped. As of June 2026, this format fidelity is what separates a compliant document from one that needs hours of manual rebuilding.
What Changes With the 2027 EU Machinery Regulation?
On 20 January 2027, EU Machinery Regulation 2023/1230 fully replaces the Machinery Directive 2006/42/EC, and it requires fully translated documentation for every machine on the EU market in the official language of each member state of use. The regulation also formally allows digital instructions, but the language obligation is unchanged: the user's language is still mandatory, and a paper copy must be available on request.
The practical effect is volume and timing pressure. Manufacturers are revisiting entire documentation sets to confirm every market has compliant, current translations before the deadline, and any product change between now and 2027 multiplies the re-translation work. Building a fast, repeatable translation workflow now, rather than a last-minute agency scramble, is the lower-risk path.
How Do You Keep Terminology Consistent and Accurate?
You keep terminology consistent by locking it in a custom glossary so every technical term, component name, hazard word, and standard reference is translated the same way across every document and language. Inconsistent terminology in safety instructions is both a usability problem and a liability, because a hazard described two different ways reads as two different hazards.
Bluente's glossary holds company-specific and jurisdiction-specific terms, and protects anything that must not change, model numbers, trademarks, standard codes. For high-stakes regulatory content, this consistency is the difference between documentation that passes a market check and documentation that raises questions. Teams that need a certified output for specific submissions can escalate those documents to human-certified translation within the same platform.
Is It Secure Enough for Pre-Launch Technical Files?
Yes. Bluente runs with zero data retention, automatic deletion of uploaded files within 24 hours, and end-to-end encryption, and your technical files are never used to train any AI model. The platform is SOC 2 Type II, GDPR, and ISO 27001 compliant.
Technical documentation for an unreleased product is commercially sensitive, and a translation step that retains those files or feeds them into model training is an unacceptable exposure. A secure, no-retention workflow lets compliance and engineering teams translate pre-launch documentation without widening the risk surface.
Frequently Asked Questions
Q: Does the EU Declaration of Conformity have to be translated? Yes. The EU Declaration of Conformity must be translated into the language or languages required by each member state where the product is sold. The translation must preserve the product identifiers, the listed directives and standards, and the signatory details exactly.
Q: Can technical documentation stay in English? Generally yes, the internal technical file can be kept in one working language such as English, but user-facing instructions and safety information must be in the local language, and authorities may request specific local-language summaries during enforcement checks.
Q: How many languages might one product need? As many as the number of EU markets you sell into, drawn from the 24 official EU languages. A product distributed across a dozen member states can require a dozen synchronized language versions of its manual and Declaration of Conformity.
Q: What is the 2027 deadline about? EU Machinery Regulation 2023/1230 fully applies from 20 January 2027, replacing the Machinery Directive. It confirms that machine documentation must be fully translated into the official language of each member state of use, with digital instructions now permitted alongside on-request paper copies.
Q: Will the warnings inside diagrams and labels get translated? Yes. Bluente uses OCR to read and translate text embedded in images, charts, and labels, so a warning or instruction baked into a figure is translated rather than left in the source language.
Q: Can I get a certified translation when a market requires one? Yes. You can produce instant AI translations for most documentation and escalate specific documents that need certified output to human-certified translation within the same platform.
