§ 02 · Hazards identification

Harmonised EU classification

CLP Annex VI · Index 030-013-00-7. A supplier SDS may add self-classified hazards — this is the legal minimum.

H400 Very toxic to aquatic life. Hazardous to aquatic environment, acute — Category 1 (Aquatic Acute 1)
H410 Very toxic to aquatic life with long lasting effects. Hazardous to aquatic environment, chronic — Category 1 (Aquatic Chronic 1)

Precautionary statements

P273 Avoid release to the environment.
P391 Collect spillage.
P501 Dispose of contents/container in accordance with local regulations.

Caution

§ 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 "zinc oxide MSDS" and a "zinc oxide 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 "zinc oxide MSDS" is today issued as an SDS.

What GHS pictograms does zinc oxide require?

Under the harmonised EU classification (CLP Annex VI), zinc oxide carries GHS09 with the signal word "Warning". Hazard statements: H400, H410. A supplier's SDS may add self-classified hazards on top of this harmonised minimum.

Where can I download an official zinc oxide 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.
