Safety Data Sheet
Getting an SDS for Carfentrazone-ethyl
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 Carfentrazone-ethyl 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
Carfentrazone-ethyl precautionary statements
CLP Annex VI assigns 3 precautionary statements to Carfentrazone-ethyl. 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
Carfentrazone-ethyl 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.

Carfentrazone-ethyl health hazards and exposure limits
Carfentrazone-ethyl hazard summary
The lowest NOAEL of 3 mg/kg was found in female rats from a 2-year chronic study and this number is used as the basis for the recommended limit. Higher doses produce both liver damage and increased urinary porphyrin excretion. No human data available; [ACGIH] The protox inhibitor herbicides (Fomesafen, Oxadiazon, Lactofen, Sulfentrazone, Carfentrazone-ethyl, Oxyfluorofen and Bifenox) can disrupt porphyrin metabolism; It has been speculated that a transient form of porphyria variegate may occur following a massive exposure or long-term exposure to lower doses. [HSDB] May cause irritation; [MSDSonline] See Fluthiacet-methyl.

Carfentrazone-ethyl 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.

Under CLP Annex VI the label for Carfentrazone-ethyl carries the pictogram Environment and the signal word is Warning.
Is Carfentrazone-ethyl flammable?
CLP Annex VI assigns Carfentrazone-ethyl 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 Carfentrazone-ethyl a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Carfentrazone-ethyl. 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 boiling point of Carfentrazone-ethyl?
The boiling point reported for Carfentrazone-ethyl is 352.5 °C (666.5 °F), range, midpoint shown (HSDB).
What is the melting point of Carfentrazone-ethyl?
The melting point reported for Carfentrazone-ethyl is -22.1 °C (-7.8 °F) (HSDB).
How should Carfentrazone-ethyl be stored?
Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must carefully resealed and kept upright to prevent leakage. Recommended storage temperature: 2-8 °C. (Hazardous Substances Data Bank (HSDB))
