Safety Data Sheet

Getting an SDS for Metsulfuron-methyl

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 Metsulfuron-methyl 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

Metsulfuron-methyl precautionary statements

CLP Annex VI assigns 3 precautionary statements to Metsulfuron-methyl. 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.

Prevention

What to do before and during handling so the hazard never happens.

Response

What to do once exposure, spillage or fire has already happened.

Disposal

What has to happen to the contents and the empty container.

05 · Names in the regulation

Metsulfuron-methyl 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.

Metsulfuron-methyl hazard summary

An eye and mild skin irritant; Urea-derived herbicides have low toxicity in animal feeding studies; [HSDB] Systemic toxicity unlikely unless large amounts ingested; [EPA Pesticides, p. 122] In a 90-day feeding study at 5000 mg/kg diet, dogs had no apparent systemic toxicity; [HSDB]

Metsulfuron-methyl carcinogenicity classification

Cancer Classification: Not Likely to be Carcinogenic to Humans

Source: Hazardous Substances Data Bank (HSDB)

An IARC group and a CLP classification answer different questions. IARC judges whether the evidence for cancer in humans is strong enough; CLP Annex VI is the legally binding EU classification. A substance can carry one and not the other.

Is Metsulfuron-methyl a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Metsulfuron-methyl. 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.
