Listed as a nutrient supplement by the US.
Listed as nutrient supplements (US)
- United States: Nutrient supplement — FDA, Substances Added to Food: FERRIC PHOSPHATE
- United States: Nutrient supplements — 21 CFR 184.1301, citing 21 CFR 170.3(o)(20)
Ferric phosphate is an iron fortificant chosen for causing almost no colour or flavour change, at the cost of being absorbed less well than the soluble iron salts.

| Australia and New Zealand | No listed food uses foundThis site has not matched this substance to any food use on this jurisdiction’s list of authorised food additives. A food additive may be used only in foods that list names. Flavourings, enzymes, processing aids and added nutrients are regulated separately and do not appear on it. | ||
| Canada | No listing matchedHealth Canada’s lists name additives without E or INS numbers, so this site matches them by exact name. A substance listed there under a name this site does not recognise has no row here. | ||
| European Union | No listed food uses foundThis site has not matched this substance to any food use on this jurisdiction’s list of authorised food additives. A food additive may be used only in foods that list names. Flavourings, enzymes, processing aids and added nutrients are regulated separately and do not appear on it. | ||

| Japan | No listing matchedThis site imports only Japan’s list of designated additives (Appended Table 1 to the Regulations for Enforcement of the Food Sanitation Act), matched by English name. Existing additives, natural flavouring agents and ordinary foods used as additives are permitted outside that list and are not imported, so an empty row does not show that Japan does not permit the substance. | ||

How much is permitted
A listing usually limits the quantity as well as the food. Only one of the forms that takes is a figure: quantum satis and good manufacturing practice permit the amount the technological effect requires and no more, which is a limit rather than the absence of one. Figures below are the range across every food category this page is listed in, and categories differ between regulators — see how much is permitted.
| South Korea | — | 1 no quantity stated |
|---|---|---|
| United States | — | 1 no quantity stated |
No regulator sets a figure for Ferric phosphate. That is not an absence of control: where the listing says quantum satis or good manufacturing practice, the quantity is limited to what the effect requires.

Common questions
Assembled from what is above, in the words the questions are usually asked in. Each answer is the same statement the relevant section makes, with the same citations behind it.
- What is Ferric phosphate?
- Ferric phosphate is an iron fortificant chosen for causing almost no colour or flavour change, at the cost of being absorbed less well than the soluble iron salts.
- What is Ferric phosphate used for in food?
- It is listed as a nutrient supplement — the role the US assigns it. This page shows every function each regulator records, with the citation for each.
- Is Ferric phosphate banned in Europe?
- No. Ferric phosphate is not on the EU's list of authorised food additives, but it would not be expected to be: every role regulators give it — nutrient supplement — the EU regulates under separate law. Its absence from the additives list says nothing about whether it is permitted in Europe.
- Where is Ferric phosphate permitted?
- Of the seven regulators this site reads, South Korea and the US permit it. Each permission is for named foods at named levels, not a blanket one; the table on this page gives them with citations.
- Is Ferric phosphate vegan?
- Yes. Ferric phosphate is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
