HEDP (Etidronic acid) Price Trend

Phosphoric Acid is a key raw material in the manufacture of HEDP (Etidronic acid). Its market in the North American region remained consolidated in the fourth quarter of 2021, with producer offers fluctuating during the quarter. The main cause for this market shift was linked to the low reliance on Chinese suppliers for fertiliser exports as well as enough domestic production. The North American demand outlook has been bolstered by a paradigm change in the phosphoric acid market trend from fertilisers to electric vehicles. As a result, the FOB USA quarterly average was set at 1650 USD/MT at the end of the quarter.
