| SDS Group | Fertiliser Description |
| Product Safety Data Sheet - Group 1 |
Products in Group 1 are solid straight Nitrogen fertilisers containing-Not less than 90% ammonium nitrate with not more than 0.2% total combustible/organic material calculated as carbon and with added matter, if any, which is inorganic and inert towards ammonium nitrate |
| |
-Less than 90% but more than 70% ammonium nitrate with other inorganic materials or more than 80% but less than 90% ammonium nitrate mixed with calcium carbonate and/or dolomite and/or mineral calcium sulphate and not more than 0.4% total combustible/organic material calculated as carbon. |
| |
-mixtures of ammonium nitrate and ammonium sulphate with more than 45% but less than 70% ammonium nitrate and not more than 0.4% total combustible/organic material calculated as carbon such that the sum of the percentage compositions of ammonium nitrate and ammonium sulphate exceeds 70%. |
| Product Safety Data Sheet - Group 2 |
Products in Group 2 are solid compound fertilisers of NPK, NP and NK types with between 70% and 90% ammonium nitrate and not more than 0.4% total combustible material. They are not capable of self sustaining decomposition i.e."cigar-burning”. |
| Product Safety Data Sheet - Group 3 |
Products in Group 3 are solid straight nitrogen fertilisers with less than 70% ammonium nitrate and not more than 0.4% total combustible materials with inert materials or with less than 80% ammonium nitrate with limestone and/or dolomite and/or mineral calcium sulpahte filler and not more than 0.4% total combustible material or with less than 45% ammonium nitrate with ammonium sulphate and not more than 0.4% combustible material. |
| Product Safety Data Sheet - Group 4 |
Products in Group 4 are solid ammonium nitrate-based compound fertilisers (NPK, NP, NK) with not more than 70% ammonium nitrate. They are not capable of self sustaining decomposition ("cigar-burning"). |
| Product Safety Data Sheet - Group 5 |
Products in Group 5 are solid straight Nitrogen fertilisers: ammonium sulphate and mixtures of ammonium sulphate with diluents. |
| Product Safety Data Sheet - Group 6 |
Products in Group 6 are solid straight Nitrogen fertilisers: urea and mixtures of urea with diluents. |
| Product Safety Data Sheet - Group 7 |
Products in Group 7 are solid compound fertilisers (NPK, NP, NK) which are not based on ammonium nitrate. |
| Product Safety Data Sheet - Group 8 |
Products in Group 8 are solid fertilisers which contain PK, P and/or K; but do not contain nitrogen. |
| Product Safety Data Sheet - Group 9 |
Products in Group 9 are fluid straight nitrogen fertilisers in the form of aqueous solutions or suspensions. |
