# Regulation (EC) No 2003/2003 of the European Parliament and of the Council of 13 October 2003 relating to fertilisers (Text with EEA relevance) EU Regulation No 2003/2003 · adopted 13 October 2003 Regulation (EC) No 2003/2003 of the European Parliament and of the Council of 13 October 2003 relating to fertilisers (Text with EEA relevance) ## Introductory text Regulation (EC) No 2003/2003 of the European Parliament and of the Council of 13 October 2003 relating to fertilisers (Text with EEA relevance) THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION, Having regard to the Treaty establishing the European Community, and in particular Article 95 thereof, Having regard to the proposal from the Commission, Having regard to the Opinion of the European Economic and Social Committee, Acting in accordance with the procedure laid down in Article 251 of the Treaty, Whereas: (1) Council Directive 76/116/EEC of 18 December 1975 on the approximation of the laws of the Member States relating to fertilisers, Council Directive 80/876/EEC of 15 July 1980 on the approximation of the laws of the Member States relating to straight ammonium nitrate fertilisers of high nitrogen content, Commission Directive 87/94/EEC of 8 December 1986 on the approximation of the laws of the Member States relating to procedures for the control of characteristics of, limits for and resistance to detonation of straight ammonium nitrate fertilisers of high nitrogen content, and Commission Directive 77/535/EEC of 22 June 1977 on the approximation of the laws of the Member States relating to methods of sampling and analysis for fertilisers, have been substantially amended several times. In accordance with the communication from the Commission to the European Parliament and the Council ‘Simpler legislation for the internal market’ (SLIM) and the Action Plan for the Single Market those Directives should be repealed and replaced by a single legal instrument, in the interests of clarity. (2) The Community legislation on fertilisers is very technical in its content. A Regulation is therefore the most appropriate legal instrument, as it imposes directly on manufacturers precise requirements to be applied at the same time and in the same manner throughout the Community. (3) In each Member State fertilisers must display certain technical characteristics laid down by mandatory provisions. These provisions, concerning more particularly the composition and definition types of fertilisers, the designations of these types, their identification and their packaging, differ from one Member State to another. By their disparity they hinder trade within the Community and should therefore be harmonised. (4) Since the objective of the proposed action, namely to ensure the internal market in fertilisers, cannot be sufficiently achieved by the Member States if there are no common technical criteria and can therefore, by reason of the scale of the action, be better achieved at Community level, the Community may adopt measures in accordance with the principle of subsidiarity as set out in Article 5 of the Treaty. In accordance with the principle of proportionality, as set out in that Article, this Regulation does not go beyond what is necessary in order to achieve this objective. (5) It is necessary to determine at Community level the designation, definition and composition of certain fertilisers (EC fertilisers). (6) Community rules on the identification, traceability and labelling of EC fertilisers and on the closure of the packages should also be laid down. (7) A procedure should be established at Community level to be followed in cases where a Member State deems it necessary to restrict the placing on the market of EC fertilisers. (8) The production of fertilisers is subject to varying degrees of fluctuation due to manufacturing techniques or basic materials. Sampling and analytical procedures may also contain variations. It is therefore necessary to authorise tolerances on the declared nutrient contents. In the interest of the agricultural user, it is advisable to keep these tolerances within narrow limits. (9) Official controls on the compliance of EC fertilisers with requirements of this Regulation concerning quality and composition should be carried out by laboratories that are approved by the Member States and notified to the Commission. (10) Ammonium nitrate is the essential ingredient of a variety of products, some of which are intended for use as fertilisers and others as explosives. It is necessary, having regard to the particular nature of ammonium nitrate fertilisers of high nitrogen content and to the consequent requirements regarding public safety, health and protection of workers, to lay down additional Community rules for EC fertilisers of this type. (11) Certain of those products could be hazardous and could in certain instances be used for purposes other than those for which they were intended. This could well endanger the security of persons and property. Manufacturers should therefore be obliged to take appropriate steps to avoid such use, and in particular to ensure the traceability of such fertilisers. (12) In the interest of public safety, it is particularly important to determine at Community level the characteristics and properties distinguishing ammonium nitrate EC fertilisers of high nitrogen content from varieties of ammonium nitrate used in the manufacture of products used as explosives. (13) Ammonium nitrate EC fertilisers of high nitrogen content should conform to certain characteristics to ensure that they are harmless. Manufacturers should ensure that all high nitrogen content ammonium nitrate fertilisers have passed a test of resistance to detonation before those fertilisers are placed on the market. (14) It is necessary to establish rules on the methods of the closed thermal cycles even if these methods may not necessarily simulate all conditions arising during transport and storage. (15) Fertilisers can be contaminated by substances that can potentially pose a risk to human and animal health and the environment. Further to the opinion of the Scientific Committee on Toxicity, Ecotoxicity and the Environment (SCTEE), the Commission intends to address the issue of unintentional cadmium content in mineral fertilisers and will, where appropriate, draw up a proposal for a Regulation, which it intends to present to the European Parliament and the Council. Where appropriate, a similar review will be undertaken for other contaminants. (16) It is appropriate to establish a procedure, to be observed by any manufacturer or its representative that wishes to include a new type of fertiliser in Annex I in order to use the marking ‘EC fertiliser’. (17) The measures necessary for the implementation of this Regulation should be adopted in accordance with Council Decision 1999/468/EC of 28 June 1999 laying down the procedures for the exercise of implementing powers conferred on the Commission. (18) Member States should lay down penalties in respect of infringements of the provisions of this Regulation. They may provide that a manufacturer which infringes Article 27 can be fined an amount equivalent to ten times the market value of the shipment that fails to comply. (19) Directives 76/116/EEC, 77/535/EEC, 80/876/EEC and 87/94/EEC should be repealed, HAVE ADOPTED THIS REGULATION: ## Title I: GENERAL PROVISIONS ### Chapter I: Scope and definitions ## 1 Scope This Regulation shall apply to products which are placed on the market as fertilisers designated ‘UK fertiliser’. ## 2 Definitions ((1)) For the purposes of this Regulation the following definitions shall apply: (a)‘Fertiliser’ means material, the main function of which is to provide nutrients for plants.

Nothing in this Regulation prevents the appropriate authority, in order to satisfy the requirements of Article 9, from using any power the appropriate authority has to prescribe that the indication of the nitrogen, phosphorus and potassium contents of fertilisers placed on the market is to be expressed in the following way: (a) nitrogen solely in the elemental form (N); and either (b) phosphorus and potassium solely in the elemental form (P, K); or (c) phosphorus and potassium solely in the oxide form (P2O5, K2O); or (d) phosphorus and potassium in both elemental and oxide forms simultaneously. Where the option is chosen to prescribe that the phosphorus and potassium contents be expressed in the form of elements, all references in the Annexes to the oxide form shall be read as being in elemental form and the numerical values shall be converted using the following factors: (a) phosphorus (P) = phosphorus pentoxide (P2O5) × 0,436; (b) potassium (K) = potassium oxide (K2O) × 0,830. 2. Nothing in this Regulation prevents the appropriate authority from using any power the appropriate authority has to prescribe that the calcium, magnesium, sodium and sulphur contents of secondary nutrient fertilisers and, where the conditions of Article 17 are fulfilled, of primary nutrient fertilisers placed on the market are to be expressed: (a) in the oxide form (CaO, MgO, Na2O, SO3); or (b) in the elemental form (Ca, Mg, Na, S); or (c) in both of these forms. To convert the calcium oxide, magnesium oxide, sodium oxide and sulphur trioxide contents into calcium, magnesium, sodium and sulphur contents, the following factors shall be used: (a) calcium (Ca) = calcium oxide (CaO) × 0,715; (b) magnesium (Mg) = magnesium oxide (MgO) × 0,603; (c) sodium (Na) = sodium oxide (Na2O) × 0,742; (d) sulphur (S) = sulphur trioxide (SO3) × 0,400. For the calculated oxide or elemental content, the figure declared shall be rounded to the nearest decimal place. 3. The appropriate authority shall not prevent the placing on the market of an ‘UK fertiliser’ labelled in both of the forms mentioned in paragraphs 1 and 2. 4. The content of one or more of the micro-nutrients boron, cobalt, copper, iron, manganese, molybdenum, or zinc in the UK fertilisers belonging to the types of fertilisers listed in sections A, B, C and D of Annex I shall be declared where the following conditions are fulfilled: (a) the micro-nutrients are added at least in the minimum quantities specified in section E.2.2 and E.2.3 of Annex I; (b) the UK fertiliser continues to satisfy the requirements of sections A, B, C and D of Annex I. 5. Where the micro-nutrients are the normal ingredients of the raw materials intended to supply primary (N, P, K) and secondary (Ca, Mg, Na, S) nutrients, they may be declared, provided that these micro-nutrients are present at least in the minimum quantities specified in sections E.2.2 and E.2.3 of Annex I. 6. The micro-nutrient content shall be declared in the following manner: (a) for fertilisers belonging to the types of fertilisers listed in section E.1 of Annex I, in accordance with the requirements set out in column 6 of that section; (b) for mixtures of fertilisers referred to in (a) containing at least two different micro-nutrients and meeting the requirements of section E.2.1 of Annex I and for fertilisers belonging to the types of fertilisers listed in sections A, B, C and D of Annex I, by indicating: (i)the total content, expressed as a percentage of the fertiliser by mass, (ii)the water-soluble content, expressed as a percentage of the fertiliser by mass, where the soluble content is at least half of the total content. Where a micro-nutrient is totally water-soluble, only the water-soluble content shall be declared. Where a micro-nutrient is chemically linked with an organic molecule, the content of the micro-nutrient present in the fertiliser shall be declared immediately following the water-soluble content as a percentage by mass of the product, followed by one of the terms ‘chelated by’, or ‘complexed by’, with the name of the organic molecule as set out in section E.3 of Annex I. The name of the organic molecule may be replaced by its initials. ## 7 Identification 1. The manufacturer shall provide UK fertilisers with the identification markings listed in Article 9. 2. If the fertilisers are packed, these identification markings shall appear on the packages or labels attached. If the fertilisers are in bulk, these markings shall appear on the accompanying documents. ## 8 Traceability Without prejudice to Article 26(3), the manufacturer shall, to ensure traceability of UK fertilisers, maintain records of the origin of the fertilisers. These records shall be available for inspection by the enforcement authority for as long as the fertiliser is being supplied to the market, and for a further period of 2 years after the manufacturer stopped supplying it. ## 9 Markings 1. ...

The manufacturer shall not take systematic advantage of the tolerances given in Annex II. 3. No tolerances are allowed in respect of the minimum and maximum contents specified in Annex I. ## 14 Fertiliser requirements A type of fertiliser may only be included in Annex I if: (a)it provides nutrients in an effective manner; (b)relevant sampling, analysis, and if required, test methods are being provided; (c)under normal conditions of use it does not adversely affect human, animal, or plant health, or the environment. ## 15 Safeguard clause 1. Where the appropriate authority has justifiable grounds for believing that a specific UK fertiliser, although satisfying the requirements of this Regulation, constitutes a risk to safety or health of humans, animals or plants or a risk to the environment, nothing in this Regulation prevents the appropriate authority from using any power the appropriate authority has to temporarily prohibit the placing on the market of that fertiliser in its territory or make it subject to special conditions. Except in the case of a decision in respect of ammonium nitrate fertilisers of high nitrogen content where the decision is outside devolved competence, the appropriate authority shall immediately inform the other appropriate authorities, giving the reasons for the decision. 2. The Secretary of State may, by regulations, in relation to a fertiliser which has been temporarily prohibited from the market under paragraph 1: (a) amend Annex 1 to impose special conditions in relation to the fertiliser, or (b) remove the fertiliser from Annex 1. (2A.) Regulations under paragraph 2 must be made as soon as reasonably practicable— (a) after the date of receipt of the information referred to in paragraph 1, or (b) where there is no such information, after the date on which the temporary prohibition begins or special conditions are imposed, as the case may be. (2B.) Except in the case of a decision in respect of ammonium nitrate fertilisers of high nitrogen content where the decision is outside devolved competence, if a decision is made not to make regulations under paragraph 2, the Secretary of State must immediately inform the other appropriate authorities. After the date of a decision not to make regulations under paragraph 2, the prohibition or special conditions imposed under paragraph 1 no longer have effect. 3. The provisions of this Regulation shall not preclude the taking of measures by the appropriate authority which are justified on grounds of public security to prohibit, restrict or hinder the placing on the market of UK fertilisers. ## Title II: PROVISIONS FOR SPECIFIC TYPES OF FERTILISERS ### Chapter I: Inorganic primary nutrient fertilisers ## 16 Scope This chapter shall apply to inorganic primary nutrient fertilisers, solid or fluid, straight or compound, including those containing secondary nutrients and/or micro-nutrients, with the minimum nutrient content established in sections A, B, C, E.2.2 or E.2.3 of Annex I. ## 17 Declaration of secondary nutrients in primary nutrient fertilisers Calcium, magnesium, sodium and sulphur content may be declared as secondary nutrient content of UK fertilisers belonging to the types of fertiliser listed in sections A, B and C of Annex I, provided that these elements are present in at least the following minimum quantities: (a)2 % calcium oxide (CaO), i.e. 1,4 % Ca; (b)2 % of magnesium oxide (MgO), i.e. 1,2 % Mg; (c)3 % of sodium oxide (Na2O), i.e. 2,2 % Na; (d)5 % of sulphur trioxide (SO3), i.e. 2 % S.

This type of fertiliser may contain inorganic or inert substances. The substances used in the manufacturing of this type of fertiliser must not increase its sensitivity to heat or its tendency to detonate. ## 26 Safety measures and controls 1. The manufacturer shall ensure that straight ammonium nitrate fertilisers of high nitrogen content comply with the provisions of section 1 of Annex III. 2. The checking, analysis and testing for official controls of straight ammonium nitrate fertilisers of high nitrogen content provided for by this chapter shall be carried out in accordance with the methods described in section 3 of Annex III. 3. To ensure the traceability of ammonium nitrate UK fertilisers of high nitrogen content placed on the market, the manufacturer shall maintain records of the names and addresses of the sites, and of the operators of the sites, at which the fertiliser and its principal components were produced. These records shall be available for inspection by the enforcement authority for as long as the fertiliser is being supplied to the market, and for a further period of 2 years after the manufacturer stopped supplying it. ## 27 Test of resistance to detonation Without prejudice to the measures referred to in Article 26, the manufacturer shall ensure that each type of UK high nitrogen content ammonium nitrate fertiliser placed on the market has passed the test of resistance to detonation described in sections 2, 3 (method 1, point 3) and 4 of Annex III of this Regulation. This test shall be carried out by one of the approved laboratories referred to in Article 30(1) .... Manufacturers shall submit the results of the test to the appropriate authority at least 5 days before placing the fertiliser on the market, or at least 5 days before the arrival of the fertiliser at the borders of the United Kingdom in the case of imports. Thereafter, the manufacturer shall continue to guarantee that all supplies of the fertiliser placed on the market are capable of passing the abovementioned test. ## 28 Packaging Ammonium nitrate fertilisers of high nitrogen content shall be made available to the final user only in packaged form. ## Title III: CONFORMITY ASSESSMENT OF FERTILISERS ## 29 Control measures 1. Nothing in this Regulation prevents the appropriate authority from using any power the appropriate authority has to subject fertilisers marked ‘UK fertiliser’ to official control measures for the purpose of verifying that they comply with this Regulation. Nothing in this Regulation prevents the appropriate authority from using any power the appropriate authority has to charge fees not exceeding the cost of tests needed for such control measures, but this shall not oblige manufacturers to repeat tests or to pay for repeated tests where the first test was made by a laboratory which fulfilled the conditions of Article 30 and where the test showed compliance of the fertiliser in question. 2.
