TDS vs SDS: technical and safety data sheet differences
A technical data sheet describes product characteristics and applications; a safety data sheet provides information on hazards and safety measures. One does not replace the other. When managing raw materials or chemical products, keep them as separate document types and check that both describe the same product reference and supplier.
What to look for in each document
A TDS can describe properties, performance and application recommendations, depending on the product and manufacturer. An SDS addresses topics such as hazards, handling and emergency response. ECHA explains the scope of safety data sheets. As an example of document organisation, Henkel provides separate ways to locate technical and safety data sheets.
Sources for SDS scope and an example of separate manufacturer document access. The workflow and template are QuiMatrix organisational suggestions.
A detergent document example
Suppose purchasing receives a TDS with a detergent description and application recommendations. It can help colleagues understand the product, but it does not establish that its safety documentation has been received. The reviewer should identify the exact reference and ask the supplier for the documents that apply. This is a file review example, not dosing or use advice.
Check product identity before comparing information
Compare the trade name, manufacturer code and supplier. A concentrate and a ready-to-use cleaner can share part of a name while having different documents. Keep the language and stated market too. If the TDS and SDS describe different references, record the uncertainty and request confirmation before treating the record as complete.
Distinguish typical values from agreed specifications
Retain the units, method and conditions accompanying each technical value. Check how the manufacturer describes it and which documents your company uses for product acceptance. If you need a batch certificate of analysis or a specification, request it separately: having a TDS does not prove those documents have been received.
Track updates separately for each document type
A revised TDS does not imply that the SDS changed, and a new SDS does not automatically replace the TDS. Keep independent versions and dates. When an update arrives, retain the previous original and record which document is being reviewed, who is responsible and which questions remain open.
Quick comparison: what to request
| Need | Document or check |
|---|---|
| Understand properties and applications | TDS for the reference; review units and conditions. |
| Consult hazards and safety measures | SDS matching the product and context. |
| Review results for a batch | Certificate of analysis where relevant, linked to the batch. |
| Confirm acceptance requirements | Agreed specification and relevant supporting documents. |
| Resolve a mismatch between files | Supplier clarification retained alongside the originals. |
Illustrative example: a team receives the TDS for CL-20 and the SDS for CL-20C. Both files are recorded as received, but product correspondence remains open until the supplier confirms which reference each document describes.
Document identification and request template
Complete one record per product and supplier. Request each document by name and record questions before marking the file as reviewed.

PRODUCT AND SUPPLIER: Internal reference / manufacturer code: Required country and language: TECHNICAL DATA SHEET Original file and source: Stated version / receipt date: Property consulted, unit and conditions: SAFETY DATA SHEET Original file and source: Stated version / receipt date: Does the product reference match?: OTHER DOCUMENTS NEEDED: Questions for supplier clarification: Owner and next action:
An organisational record, not a TDS or SDS. Do not use it as a substitute for either document.
Before you finish
- Every file has an identified document type.
- Product and supplier codes match or have a clarification.
- Versions are retained separately.
- Questions about specifications or batches are not closed using another document type.
How QuiMatrix can help
QuiMatrix connects TDS, SDS and other documents to products and suppliers. Teams can consult originals and organise reviews and requests. Data validation and technical decisions remain with your team.
