Division 4 The term ‘mineral fertiliser’ may be used only if the fertiliser belongs to PFC 1(C) and fulfils the following additional conditions:

the mineral fertiliser must not contain more than 1 % by mass of organic carbon (C_org), other than organic carbon from:

1. (i)

   chelating or complexing agents referred to in point 3 of CMC 1 in Part II of Annex II,

2. (ii)

   nitrification inhibitors, denitrification inhibitors or urease inhibitors referred to in point 4 of CMC 1 in Part II of Annex II,

3. (iii)

   coating agents referred to in point 1(a) of CMC 9 in Part II of Annex II,

4. (iv)

   urea (CH₄N₂O), or

5. (v)

   calcium cyanamide (CaCN₂);

where phosphorus (P) is a declared nutrient, the declared phosphorus content shall consist only of phosphorus in the phosphatic form, and the mineral fertiliser shall fulfil at least one of the following solubility criteria:

1. (i)

   water solubility: minimum level 40 % of total phosphorus (P),

2. (ii)

   solubility in neutral ammonium citrate: minimum level 75 % of total phosphorus (P), or

3. (iii)

   solubility in formic acid (only for soft rock phosphate): minimum level 55 % of total phosphorus (P);

where nitrogen (N) is a declared nutrient, the declared nitrogen content shall consist only of the sum of nitric nitrogen, ammoniacal nitrogen, ureic nitrogen, and nitrogen from methylene-urea, from isobutylidenediurea, and from crotonylidenediurea.
