Dimethyltin dichloride hazard class and category

GHS hazard classes Dimethyltin dichloride falls into
Hazard class Category From code Pictogram
Acute toxicity - oral GHS chapter 3.1 Category 3 H301 GHS06
Acute toxicity - dermal GHS chapter 3.1 Category 3 H311 GHS06
Acute toxicity - inhalation GHS chapter 3.1 Category 1 or 2 H330 GHS06
Skin corrosion/irritation GHS chapter 3.2 Category 1A or 1B or 1C H314 GHS05
Specific target organ toxicity - repeated exposure GHS chapter 3.9 Category 1 H372 GHS08

Where two values are shown with “or”, the hazard statement is shared by more than one category or by more than one class, and the code alone does not say which. H272, for example, belongs to oxidising liquids and to oxidising solids — the physical state decides. The binding answer for a specific entry is in the CLP Annex VI table itself.

Safety Data Sheet

Getting an SDS for Dimethyltin dichloride

A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of Dimethyltin dichloride issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.

04 · Precautionary statements

Dimethyltin dichloride precautionary statements

CLP Annex VI assigns 12 precautionary statements to Dimethyltin dichloride. They are grouped the way a label groups them: what to do before handling, what to do when something has already happened, how to store it and how to dispose of it.

05 · Names in the regulation

Dimethyltin dichloride name in 23 EU languages

CLP Annex VI Part 3 is published in every language edition of the regulation, and the identification column is written out in each of them. Nothing below is translated by us: each line is the name as that edition prints it. Under Art. 18(2) the substance name from Annex VI is a lawful product identifier, so this is the wording to put on a label going to that market — and where the cell lists several designations, any one of them qualifies.

Dimethyltin dichloride occupational exposure limits

US occupational exposure limits reported for Dimethyltin dichloride. PEL is enforceable (OSHA), REL is a recommendation (NIOSH), IDLH is the concentration at which escape becomes impossible without injury.
Limit Value Source
PEL 0.1 [mg/m3], as Sn Haz-Map, Information on Hazardous Chemicals and Occupational Diseases
IDLH 25.0 [mg/m3], as Sn Haz-Map, Information on Hazardous Chemicals and Occupational Diseases

These are United States values. The European Union sets its own indicative and binding limits, and the figure that applies at a given workplace is the one in the local regulation — not the one shown here.

What does a Dimethyltin dichloride label have to show?

Under CLP Annex VI the label for Dimethyltin dichloride carries the pictograms Health hazard, Skull and crossbones and Corrosion and the signal word is Danger.

Is Dimethyltin dichloride flammable?

CLP Annex VI assigns Dimethyltin dichloride no flammability hazard class. That is not a statement that it cannot burn: the harmonised list only records the hazards that were assessed for it.

Is Dimethyltin dichloride a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Dimethyltin dichloride. Annex VI is a list of agreed classifications, not a list of substances found safe, so this is an absence of a classification rather than a clean bill of health.
