§ 02 · Hazards identification

Harmonised EU classification

CLP Annex VI · Index 607-002-00-6. A supplier SDS may add self-classified hazards — this is the legal minimum.

Concentration / form dependent — CLP Note B

Acetic acid is placed on the market in different concentrations or forms whose classification can differ. This page shows the harmonised Annex VI entry for the substance as such — always match the supplier's SDS to the concentration and form you actually use.

H226 Flammable liquid and vapour. Flammable liquid — Category 3 (Flam. Liq. 3)
H314 Causes severe skin burns and eye damage. Skin corrosion — Category 1 (Skin Corr. 1)

Precautionary statements

§ 13 · Disposal considerations

Dispose of waste and residues in accordance with local and national regulations — in the EU under the Waste Framework Directive 2008/98/EC. Never discharge to drains or municipal waste; hand contaminated packaging and unused product to an authorised waste-disposal company. The supplier's SDS section 13 lists the applicable waste codes for the specific product.

MSDS vs SDS

MSDS vs SDS: is there a difference?

MSDS (Material Safety Data Sheet) is the older name for the same document. In the US, OSHA's Hazard Communication Standard (2012) adopted the GHS-standardised 16-section Safety Data Sheet; in the EU the format is set by REACH Annex II. So a "acetic acid MSDS" and a "acetic acid SDS" refer to the same document — today it is issued as an SDS. Full breakdown of the differences →

§ 16 · Sources

Reference aid only. This page summarises the harmonised EU classification and computed storage guidance — it is not a Safety Data Sheet and does not replace one. Always verify hazards, handling and storage against the supplier's SDS (sections 7 and 10) and local regulations before use. Page updated 2026-07-27.

Frequently asked questions

Is an MSDS the same as an SDS?

In practice, yes. MSDS (Material Safety Data Sheet) is the older name for the same document. In the US, OSHA's Hazard Communication Standard (2012) adopted the GHS-standardised 16-section Safety Data Sheet; in the EU the SDS format is set by REACH Annex II. A document you find labelled "acetic acid MSDS" is today issued as an SDS.

What GHS pictograms does acetic acid require?

Under the harmonised EU classification (CLP Annex VI), acetic acid carries GHS02 and GHS05 with the signal word "Danger". Hazard statements: H226, H314. A supplier's SDS may add self-classified hazards on top of this harmonised minimum.

What should acetic acid never be stored with?

Based on its storage classes (Flammable liquids, Organic acids), acetic acid must not share storage with: Bases; Cyanides & sulfides; Organic peroxides & self-reactives; Oxidizing acids; Oxidizers; Water-reactives. Verify against the supplier's SDS sections 7 and 10 before finalising storage.

Where can I download an official acetic acid SDS PDF?

From your own supplier — an SDS is issued per product and supplier, so the correct PDF for an inspection is the one matching the product you actually purchased. The supplier links on this page lead to the official SDS libraries of major distributors.
