EU Fertilizer Regulation 2019/1009 for Water-Soluble Fertilizers: What Importers Must Know

EU fertilizer regulation 2019/1009 in brief

EU fertilizer regulation 2019/1009 sets the rules for making EU fertilising products available on the market and has applied since 16 July 2022. It creates a harmonised, CE-marked route to market that sits alongside — not instead of — the national fertiliser rules that still govern products sold inside a single Member State.

For manufacturers outside the EU, the regulation is voluntary in principle but decisive in practice. A product that is not CE-marked under it cannot carry the CE mark or benefit from free circulation, so each Member State's national regime applies instead. Professional buyers increasingly request CE documentation because it is the only route that removes the need for separate national authorisations.

Where water-soluble products fit in EU fertilizer regulation 2019/1009

The regulation classifies products by Product Function Category (PFC). Water-soluble salts such as monopotassium phosphate, potassium nitrate, calcium nitrate and fully soluble NPK blends are inorganic macronutrient fertilisers under PFC 1(C). Solid products fall under PFC 1(C)(I); liquid formulations fall under PFC 1(C)(II).

Within each, "straight" means a declared content of only one macronutrient, while "compound" means two or more. MKP 0-52-34 declares both phosphorus and potassium, so it is a compound solid inorganic macronutrient fertiliser — a classification detail that shapes the declaration table on the label.

Component Material Categories (CMCs) define the permitted inputs. Technical-grade mineral salts from virgin raw materials normally qualify under CMC 1 (virgin material substances and mixtures), while recovered or precipitated phosphates follow dedicated CMCs and require additional supporting evidence.

Conformity, contaminants and documents

A product must meet the PFC requirements and the contaminant limits in the Annexes — cadmium, hexavalent chromium, lead, mercury, nickel, arsenic, copper and zinc, plus biuret where the product contains urea — before the CE mark is affixed.

The practical document set for a shipment usually includes:

• Conformity assessment: normally internal production control, supported by testing of the relevant parameters.
• EU Declaration of Conformity: issued by the manufacturer or the authorised representative.
• Technical documentation: maintained and made available to market surveillance authorities.
• Traceability: batch identity and production records that link a delivered bag to a specific test.
• Responsible person: a non-EU manufacturer needs an EU-based importer or authorised representative identified in the documentation.

Labelling duties under EU fertilizer regulation 2019/1009

Annex III governs the label. Declared nutrient content must be given in the forms the regulation prescribes, and where a nutrient is claimed as water-soluble, the soluble fraction must be declared separately. For a fully water-soluble product, water-soluble P2O5 is effectively the whole total content — worth showing clearly, because growers buy on solubility, not on total content alone.

Labels also carry the product function category, the PFC designation or the wording "EU fertilising product", net mass or volume, storage instructions where relevant, and the contact details of the responsible person in the EU. Liquid products are declared by mass and/or volume, with density stated when volume is used.

What changes for importers and distributors

Stocking both CE-marked and nationally registered products is possible, but the two routes cannot be merged into a single claim.

• Request the EU Declaration of Conformity, not only a certificate of analysis.
• Confirm the PFC and CMC pathway matches the actual product, especially for blends.
• Verify labels: nutrient forms, water-soluble declarations, CE mark and importer details.
• Keep documentation aligned with each shipment; surveillance checks start with paperwork.

FAQ

Question: Is EU fertilizer regulation 2019/1009 mandatory? Answer: No. It is an optional harmonisation route: a product that complies can be CE-marked and sold across the EU, while products that do not comply remain subject to national rules.

Question: Can monopotassium phosphate be CE-marked as a water-soluble fertilizer? Answer: Yes, provided it is made from permitted component materials, meets PFC 1(C) requirements and contaminant limits, and carries the correct conformity assessment and labelling.

Question: Which PFC applies to liquid water-soluble fertilizers? Answer: PFC 1(C)(II), liquid inorganic macronutrient fertiliser, either straight or compound depending on how many macronutrients are declared.

Question: Do national registrations still apply to CE-marked products? Answer: Member States cannot require additional national authorisation for a compliant CE-marked fertilising product, but national rules continue to apply to products placed on the market outside that route.
