Safety Data Sheet
Getting an SDS for Fumaric Acid
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 Fumaric Acid 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
Fumaric Acid precautionary statements
CLP Annex VI assigns 6 precautionary statements to Fumaric Acid. 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
Fumaric Acid 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.

All 23 language editions of Annex VI carry this entry. Irish is the twenty-fourth official EU language and has no line here for a different reason: no consolidated CLP text has ever been published in Irish, so there is no Irish edition of Annex VI to quote a name from.

What does a Fumaric Acid label have to show?
Under CLP Annex VI the label for Fumaric Acid carries the pictogram Exclamation mark and the signal word is Warning.
Is Fumaric Acid flammable?
CLP Annex VI assigns Fumaric Acid 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 273 °C (523.4 °F), open cup (HSDB).
Is Fumaric Acid a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Fumaric Acid. 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 Fumaric Acid?
The boiling point reported for Fumaric Acid is 200 °C (392 °F), sublimes (HSDB).
What is the melting point of Fumaric Acid?
The melting point reported for Fumaric Acid is 301.11 °C (574 °F), range, midpoint shown (CAMEO).
How should Fumaric Acid be stored?
The bulk material should be stored in a well-closed container in a cool, dry place. (Hazardous Substances Data Bank (HSDB))
