§ 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 "toluene diisocyanate MSDS" and a "toluene diisocyanate SDS" refer to the same document — today it is issued as an SDS. Full breakdown of the differences →

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 "toluene diisocyanate MSDS" is today issued as an SDS.
What GHS pictograms does toluene diisocyanate require?
Under the harmonised EU classification (CLP Annex VI), toluene diisocyanate carries GHS06 and GHS08 with the signal word "Danger". Hazard statements: H351, H330, H335, H315, H319, H334, H317, H412. A supplier's SDS may add self-classified hazards on top of this harmonised minimum.
Where can I download an official toluene diisocyanate 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.
