Magnesium Hydroxide Price Trend and Forecast 2026-2027

Germany remained the dearest of all the tracked Magnesium Hydroxide markets through the first half of 2026 (H1 2026), with the price up by 1.7%, from a value of USD 1.15/KG in Q1 to USD 1.17/KG in Q2. The halogen-free flame retardant demand kept rising in the cable and wire manufacturing sector, with the steady wastewater treatment buying adding to it, continuing a slow uptrend that's been running back through most of the year 2025. The global average moved from a value of USD 0.876/KG to USD 0.895/KG over the period, a gain of 2.2 percent. For the second half of 2026 (H2 2026), one can figure a range of USD 0.90 to 1.00/KG worldwide, underpinned by the regulatory pressure against the halogenated flame retardants and the steady flue gas desulfurisation demand.

Magnesium Hydroxide, or Mg(OH)2, occurs in nature as the mineral brucite and gets produced commercially by treating the seawater or brine with lime or dolime. The reaction precipitates a fine white powder, then it's filtered, washed, and either dried or calcined depending on the grade in question. The flame retardant grade leads the demand. When heated above 330 degrees Celsius, the compound decomposes endothermically, releasing a water vapour that suppresses the combustion in cables, plastics, and construction materials, without the toxicity of the halogenated alternatives. The wastewater treatment sits close behind, neutralising the acidic effluent and controlling the sulfur dioxide in flue gas desulfurisation. The pharmaceutical antacid and food additive use make up the rest. The brine and seawater processing costs anchor the price. The calcination energy costs and the pace of the halogen-free regulation make up the balance.

Magnesium Hydroxide Price Forecast for 2026

Magnesium Hydroxide entered the second half of 2026 (H2 2026) on a steady footing. The flame retardant demand for the low-smoke, zero-halogen cable compounds had climbed through the H1, and the wire and cable makers kept adding halogen-free lines. The brine processing and calcination energy costs rose gradually alongside that, and the cost base held across most of the producing regions.
