France Sets 2030 Cadmium Cap for Phosphate Fertilizer at 20 mg/kg

France has adopted a staged reduction path for cadmium in phosphate fertilizers that will tighten the national limit to 20 milligrams of cadmium per kilogram of phosphorus pentoxide by 2030. The measure is part of a broader package of four regulatory texts covering contaminant levels and application limits for fertilizers and growing media.

The timetable begins on January 1, 2027, when phosphate fertilizers will be capped at 60 mg of cadmium per kilogram of P2O5, matching the threshold in the European Union fertilizer framework. France will also cap cadmium applied through mineral fertilizers at 3 grams per hectare per year.

The limit falls again in 2028 and 2030

From January 1, 2028, the maximum cadmium concentration in phosphate fertilizers will fall to 40 mg/kg P2O5. From January 1, 2030, it will fall again to 20 mg/kg P2O5, the target recommended by France's food, environment and occupational health agency ANSES.

ANSES has recommended limiting total cadmium applications to agricultural soils to 2 grams per hectare per year and setting a 20 mg/kg P2O5 ceiling for phosphate fertilizers. The French government says the staged approach is designed to move toward that target while allowing fertilizer suppliers, farmers and the wider input chain time to adapt.

Cadmium is a fertilizer and soil issue, not just a product specification

Cadmium occurs naturally in some phosphate rock used to manufacture fertilizers. Repeated applications can add the metal to agricultural soils, where it can persist and in some cases move into crops. That is why the French framework combines concentration limits in fertilizer products with limits on how much of certain contaminants may be applied to land.

The wider package also establishes thresholds for other trace metals, organic contaminants, pathogens and physical impurities such as plastics, glass and metals. The government says the rules are intended to create a common safety baseline for fertilizer materials, including products derived from recycling.

Supply security remains part of the regulatory calculation

France has left room to adjust the implementation calendar if future official assessments show that technology, socioeconomic conditions or fertilizer-supply security make the planned timetable impractical. That caveat matters because phosphate rock varies substantially in cadmium content by origin, and tighter limits can affect sourcing and processing requirements.

The cadmium-reduction decree is also being notified to the European Commission. For fertilizer producers and importers, the practical issue is therefore not only compliance with a lower number on a specification sheet, but the ability to source lower-cadmium phosphate inputs or use processing methods that can reliably meet the tighter limits.

Why this matters for fertilizer markets

A 20 mg/kg P2O5 ceiling is materially tighter than the 60 mg/kg level that will apply in 2027. If the timetable holds, suppliers serving France will have to plan several years ahead around raw-material origin, blending, processing economics and product registration. Farmers may also see the effects through changes in available fertilizer formulations, sourcing patterns and potentially costs.

The regulation does not mean every phosphate fertilizer currently sold in France becomes non-compliant immediately. The thresholds are staged, and the 20 mg/kg target does not take effect until 2030. The important development is that France has now put a clear downward trajectory into regulation rather than leaving the lower target as a policy aspiration.
