Check your safety data sheet for errors New
Upload the SDS you prepared or received from a supplier and see missing sections, inconsistencies between sections and regulatory errors within seconds.
- Your file is deleted right after the analysis; its content is not stored.
- We do not show the correct value: the report points to where the problem is and its legal basis.
- This is a preliminary check; it does not replace expert review or a compliance certificate.
Who is it for?
Preparers
Formulators, consultants and chemists who write their own SDS: catch gaps and inconsistencies between sections before you send it out.
Recipients
Companies, safety officers, purchasing and quality teams who receive an SDS from a supplier: run a quick first check on incoming SDSs and pass the findings back to your supplier.
How it works
- Upload your Word (.docx, .doc) or PDF file (up to 10 MB; a PDF needs a text layer).
- Sections, components and classification are read and compared with the rule list.
- With a free account you see where each finding is and what kind it is.
Sample report

What do we check?
Checks point to the location of a problem without giving values. The basis is REACH Annex II and Regulation (EC) No 1272/2008 (CLP).
- Presence and order of the 16 sections and their mandatory subsections
- Section 1: product identifiers, supplier and emergency telephone number
- Section 2: classification, signal word, pictograms and H/P statements agree with each other
- Section 3: CAS number validity, concentration ranges and component information
- Consistency between sections 2 and 3 (does the mixture classification fit the components)
- Section 9 physical state and flash point against the classification
- Section 14 transport information against section 2
- Section 16 abbreviations, sources and revision information
- Mandatory headings for the document language and the selected market (KKDİK / REACH)
Frequently asked questions
What is checked?
The structure of the 16 sections, the mandatory information in sections 1, 2, 3, 9, 14 and 16, and consistency between sections. The details appear in the report in your account.
Is my file stored?
No. The file is held in memory only while it is analysed, never written to disk, and deleted afterwards.
Why don't you show the correct value?
The report shows where the problem is and its basis, not the value. You can prepare a corrected SDS in the Chemoris wizard.
Can I check an SDS I received from a supplier?
Yes. Recipients are welcome; the report shows the findings you can pass back to your supplier.
Is it free, does it cost credits?
Creating an account and checking are free and use no credits. A fair-use policy applies to prevent abuse.
Does a scanned PDF work?
No. The PDF needs a selectable text layer; scanned images cannot be read.
Is this a compliance certificate?
No. It is an automatic preliminary check and does not replace review by a competent person.
