Safety Data Sheet
Getting an SDS for Pendimethalin
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 Pendimethalin 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
Pendimethalin precautionary statements
CLP Annex VI assigns 3 precautionary statements to Pendimethalin. 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.
Disposal
What has to happen to the contents and the empty container.

05 · Names in the regulation
Pendimethalin 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.

Pendimethalin carcinogenicity classification
Cancer Classification: Group C Possible Human Carcinogen

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.

10 · Handling and storage
Pendimethalin storage and handling
Pendimethalin storage conditions
Store above 40 °F. Extended storage at temperatures less than 40 °F can result in the formation of crystals on the bottom of the container. If crystallization does occur, store the container on its side at room temperature (70 °F) and rock occasionally until crystals redissolve. Do not store near food or feed products.
