MSC 85/26/Add.2ANNEX 3Page 84AMMONIUM NITRATE BASED FERTILIZER (non-hazardous)DESCRIPTIONCrystals, granules or prills non-cohesive when dry. Wholly or partly soluble in water.Ammonium nitrate based fertilizers transported in conditions mentioned in this schedule areuniform mixtures containing ammonium nitrate as the main ingredient within the followingcomposition limits:Notes:.1 not more than 70% ammonium nitrate with other inorganic materials;.2 not more than 80% ammonium nitrate mixed with calcium carbonate and/ordolomite and not more than 0.4% total combustible organic material calculated ascarbon;.3 nitrogen type ammonium nitrate based fertilizers containing mixtures ofammonium nitrate and ammonium sulphate with not more than 45% ammoniumnitrate and not more than 0.4% total combustible organic material calculated ascarbon; and.4 uniform ammonium nitrate based fertilizer mixtures of the nitrogen, phosphate orpotash, containing not more than 70% ammonium nitrate and not morethan 0.4% total combustible organic material calculated as carbon or with notmore than 45% ammonium nitrate and unrestricted combustible material.Fertilizers within these composition limits are not subject to the provisions of thisschedule when shown by a trough Test (see UN Manual of Tests and Criteria,part III, subsection 38.2) that they are liable to self-sustaining decomposition or ifthey contain an excess of nitrate greater than 10% by mass.1. All nitrate ions for which there is present in the mixture a molecular equivalent ofammonium ions should be calculated as ammonium nitrate.2. The transport of ammonium nitrate materials which are liable to self-heating sufficient toinitiate decomposition is prohibited.3. The NPK proportions for a fertilizer should not be used as a guide to its ability to undergoself-sustaining decomposition as this depends on the chemical species present (refer toUN Manual of Tests and Criteria, part III, subsection 38.2).4. This schedule may only be used for substances that do not exhibit explosive properties ofclass 1 when tested in accordance to Test Series 1 and 2 of class 1 (see UN Manual ofTests and Criteria, part I).5. This schedule may only be used if the chemical or physical properties of an ammoniumnitrate based fertilizer are such that when tested it does not meet the established definingcriteria of any class.I:\MSC\85\26-Add-2.doc
