Safety data sheets

When do you need a safety data sheet?

Suppliers of a hazardous substance or mixture must provide their recipients with a safety data sheet (SDS) (Article 31 REACH). This is an EU requirement for selling: it must be provided free of charge at the latest with the first delivery, on paper or electronically, and in the official language of the country where the product is placed on the market.

An SDS can also be required on request for unclassified mixtures, for example if they contain certain hazardous substances above set limits.

Classification when your supplier's data does not fit

We also take over the classification of your substance or mixture under the CLP Regulation for the data sheet. This is necessary if your supplier's classification is wrong, outdated or if EU rules differ from those in the country of origin, for example a harmonised classification under CLP Annex VI or different limits than in GHS systems outside the EU. We justify every classification clearly so that you can demonstrate it to authorities and customers.

Written by hand, not generated by a computer

Our safety data sheets are not generated automatically. A competent person deliberately writes each data sheet by hand, section by section, and checks every entry against the formula, raw material data and current legislation. The result is a data sheet that stands up to critical review by authorities or customers.

We also design each data sheet so that it can be displayed in the workplace: classification, hazard and precautionary statements, protective measures and first aid are clearly structured and highlighted, so that all important information can be found at a glance.

What we do for you

Service	Result
New safety data sheet	SDS with all 16 sections under Annex II
Check of existing data sheets	list of deficiencies and corrected version
Classification under CLP	our own checked classification if your supplier's is wrong or EU rules differ
Translation	SDS in the languages of your target countries
Update	after new classifications, ATPs or formula changes
UFI in section 1.1	possible instead of the label for mixtures for industrial use only and for unpackaged mixtures; otherwise the UFI belongs on the label and is optional in the SDS

Common deficiencies in data sheets from outside the EU

• outdated structure instead of the current version of Annex II
• classification under other countries' GHS systems instead of CLP
• missing EU occupational exposure limits and national information
• wrong or missing emergency telephone number and supplier details
• sections only in English instead of the national language

What we need from you

• Formula or composition with CAS numbers and percentages
• Existing data sheet (if available)
• Physical and chemical data, e.g. flash point, pH, density
• Intended use and target countries

Good to know

A safety data sheet must be prepared by a competent person who is suitably trained and receives refresher training (REACH Annex II, section 0.2.3). Our data sheets are prepared by a competent person with additional qualification in safety data sheets and CLP classification, whose competence is refreshed regularly.
