Safety Data Sheet
Getting an SDS for Chlormequat Chloride
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 Chlormequat Chloride 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
Chlormequat Chloride precautionary statements
CLP Annex VI assigns 7 precautionary statements to Chlormequat Chloride. 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.

05 · Names in the regulation
Chlormequat Chloride 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.

Chlormequat Chloride health hazards and exposure limits
Chlormequat Chloride hazard summary
A mild eye irritant; Can be absorbed through skin; The substance may cause effects on the nervous system: cholinergic symptoms without acetylcholinesterase inhibition. [ICSC] An irritant; Can be absorbed through skin; Effects in high-dose animal studies include convulsions; [MSDSonline] Toxic to hamster embryos; No human data; [REPROTOX]

Chlormequat Chloride carcinogenicity classification
Studied by the US National Toxicology Program: TR-158: Bioassay of (2-Chloroethyl)trimethylammonium Chloride (CCC) for Possible Carcinogenicity (CASRN 999-81-5) (1979 )
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.
