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

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.

11 · Questions
Imidacloprid — frequently asked questions
What is the CAS number of Imidacloprid?
The CAS number of Imidacloprid is 138261-41-3. Its EC number is 428-040-8.
What is the chemical formula of Imidacloprid?
The molecular formula of Imidacloprid is C9H10ClN5O2 and its molecular weight is 255.66 g/mol.
What does a Imidacloprid label have to show?
Under CLP Annex VI the label for Imidacloprid carries the pictograms Skull and crossbones and Environment and the signal word is Danger.
Is Imidacloprid flammable?
CLP Annex VI assigns Imidacloprid 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 Imidacloprid a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Imidacloprid. 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.
What is the melting point of Imidacloprid?
The melting point reported for Imidacloprid is 144 °C (291.2 °F) (HSDB).
How should Imidacloprid be stored?
Keep container tightly closed in a dry and well-ventilated place. Storage class (TRGS 510): Non Combustible Solids (Hazardous Substances Data Bank (HSDB))
