Article 4
1. Where an EU fertilising product contains or consists of by-products referred to in Article 1(1), first subparagraph and in Article 2, first paragraph, points (b) to (f), and has a selenium (Se) content exceeding 10 mg/kg dry matter, the selenium content shall be indicated. 2. Where an EU fertilising product contains or consists of by-products referred to in Article 1(1), first subparagraph and in Article 2, first paragraph, points (b), (c) and (g), and has a chloride (Cl-) content exceeding 30 g/kg dry matter, the chloride content shall be indicated, unless the EU fertilising product is produced through a manufacturing process where chloride containing substances or mixtures have been used with the intention of producing or including alkali metal salts or alkaline earth metal salts, and information on these salts is provided in accordance with Annex III. 3. When the content of selenium or chloride is indicated in accordance with paragraphs 1 and 2, it shall be clearly separated from nutrient declaration and it may be expressed as a range of values. 4. Where the fact that such an EU fertilising product contains selenium or chloride below the limit values in paragraphs 1 and 2 follows certainly and uncontestably from the nature or manufacturing process of the by-product or of the EU fertilising product containing such a by-product, as applicable, the label may contain no information on these parameters, without verification (such as testing), at the responsibility of the manufacturer.
