Translation agency vs. specialist company: who should translate your safety data sheet?

MSDS-Europe – Compass to chemical safety – Translation agency vs. specialist company: who should translate a Safety Data Sheet?

 

For companies dealing with hazardous substances and mixtures, the quality of their Safety Data Sheet (SDS) translations is of paramount importance.

A Safety Data Sheet (SDS) is not merely a mandatory document; it plays a vital role in ensuring chemical safety in the workplace and legal compliance. Under EU rules, SDSs must be supplied in an official language of the country where the product is placed on the market—so translating them is a legal obligation. A faulty translation can lead to misunderstandings, safety risks and legal consequences.

 

So the question arises: should we have our SDS translated by a translation agency or by a chemical safety specialist company?

Below, we compare the two approaches to help you make an informed decision.

Translation agency – linguistic experts: pros and cons

Pros:

A conventional agency provides professional linguistic services, often with native-speaker translators. Their main strength is linguistic correctness and clarity. They can also translate quickly into multiple languages—useful if the SDS must accompany a product into several markets.

In addition, agencies usually grant discounts for repeated segments, making bulk or partially repetitive documents more cost-effective.

Cons:

Most agencies offer general linguistic expertise and may lack in-depth knowledge of the CLP Regulation or REACH compliance. Even technical translators can struggle, as the law requires that an SDS be compiled by a competent person—i.e. someone qualified and experienced in chemical safety.

A skilled linguist alone may therefore not meet this requirement. Even if an agency assigns an experienced technical translator, terminology, hazard classes or legal citations can still be misinterpreted.

Hence, a professional review by a chemical safety expert is often needed after translation. This adds time and cost and partly offsets the agency’s advantages.

During that review, missing data may need to be added, CAS/EC numbers verified, the correct classification determined, and OEL values inserted—crucial for legal compliance and market acceptance.

Chemical safety specialist company – expertise and compliance

Specialist firms focus on documents like SDSs. They have the required know-how and experience to ensure an SDS translation is not only linguistically sound but also compliant. They employ competent persons who keep up with REACH, CLP, etc. Their output often counts as a newly compiled SDS, tailored to local rules.

They know the official terminology and which parts must remain verbatim from legislation (e.g. H- and P-statements).

They also check classification and H-/P-statements; if the source contains errors or outdated data (e.g. changed limits, a new CLP hazard class), they flag and correct it. This helps ensure the translated SDS is usable and lawful in the target country.

Specialist expertise is a premium service and may cost more than a general agency, but it minimises risk.

Consequences and liability of a faulty translation

A faulty SDS translation can cause misclassification or mislabelling, jeopardising safety and reputation.

Legally, the company placing the product on the market (manufacturer/importer) remains responsible for the SDS. Even if an agency did the work, liability rests with the supplier under REACH. Inaccurate information may lead to fines or, in extreme cases, legal action.

Which solution should you choose?

SDS translation requires both linguistic precision and professional accuracy. If your company has an in-house chemical safety expert to review the draft, an agency may suffice. Without such expertise, a specialist firm is the safer choice—they provide a compliance-focused service and reduce long-term risk.

Quick questions and answers

What is the difference between a general agency and a specialist company in SDS translation?
A specialist company not only employs native translators but also has deep legal expertise (REACH, CLP), so the translation is compliant as well as linguistically correct.
Why may an SDS translation cost more at a specialist firm?
Their legal and scientific checks minimise errors, saving money and reducing liability in the long run.
What are the impacts of a faulty SDS translation?
It can lead to misleading classification or labelling, posing safety risks, fines and liability for the supplier.
When is an agency enough and when is a specialist company necessary?
If only a linguistic translation is needed and an in-house expert can review it, an agency may suffice; otherwise, choose a specialist firm or have the draft reviewed by one.
