03 · GHS classification
Diclofop-methyl hazard classification
Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
Diclofop-methyl pictograms and signal word
Diclofop-methyl hazard class and category
| Hazard class | Category | From code | Pictogram |
|---|---|---|---|
| Acute toxicity - oral GHS chapter 3.1 | Category 4 | H302 | GHS07 |
| Skin sensitisation GHS chapter 3.4 | Category 1 or 1A or 1B | H317 | GHS07 |
| Hazardous to the aquatic environment - acute GHS chapter 4.1 | Category 1 | H400 | GHS09 |
| Hazardous to the aquatic environment - chronic GHS chapter 4.1 | Category 1 | H410 | GHS09 |
Where two values are shown with “or”, the hazard statement is shared by more than one category or by more than one class, and the code alone does not say which. H272, for example, belongs to oxidising liquids and to oxidising solids — the physical state decides. The binding answer for a specific entry is in the CLP Annex VI table itself.
Diclofop-methyl hazard statements (H-codes)
| Code | Hazard statement |

| H302 | Harmful if swallowed. |
| H317 | May cause an allergic skin reaction. |
| H400 | Very toxic to aquatic life. |
| H410 | Very toxic to aquatic life with long lasting effects. |

Safety Data Sheet
Getting an SDS for Diclofop-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 Diclofop-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
Diclofop-methyl precautionary statements
CLP Annex VI assigns 12 precautionary statements to Diclofop-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
Diclofop-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.

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
Diclofop-methyl — frequently asked questions
What is the CAS number of Diclofop-methyl?
The CAS number of Diclofop-methyl is 51338-27-3. Its EC number is 257-141-8.
What is the chemical formula of Diclofop-methyl?

What does a Diclofop-methyl label have to show?
Under CLP Annex VI the label for Diclofop-methyl carries the pictograms Exclamation mark and Environment and the signal word is Warning.
Is Diclofop-methyl flammable?
CLP Annex VI assigns Diclofop-methyl 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. The flash point reported for it is 38 °C (100.4 °F), Closed cup (HSDB).
Is Diclofop-methyl a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Diclofop-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.
What is the boiling point of Diclofop-methyl?
The boiling point reported for Diclofop-methyl is 176 °C (348.8 °F), range, midpoint shown, at 0.1 mmHg (reduced pressure) (HSDB).
What is the melting point of Diclofop-methyl?
The melting point reported for Diclofop-methyl is 40 °C (104 °F), range, midpoint shown (HSDB).
How should Diclofop-methyl be stored?
Store where contamination of fertilizer, seed, and foodstuffs will not occur. (Hazardous Substances Data Bank (HSDB))
