Restraining Factor

"Volatility in Raw Material Prices and Supply Chain Dependence Potentially Impede Market Growth"

Natural constraints for the Magnesium Oxide Market include unpredictable prices of raw materials and dependence on supply chains. China holds most magnesite deposits together with the production capacity of magnesium oxide worldwide which gives global markets their extensive dependence on Chinese exports. The Chinese market's disruptions which include environmental-triggered production constraints or export bans create both market price instability along with reduced supply availability. Supply constraints due to Chinese dependency make industrial customers less able to meet their requirements thus disrupting their operational activities. These problems become more acute when combined with freight cost fluctuations and logistical obstacles that most significantly affect periods of global tension or pandemic events. The cost of producing MgO materials rises when energy price variations affect the manufacturing techniques of both DBM and FM varieties which consume large amounts of energy. End-users face difficulties in long-term planning because global sources remain limited. As a result this discourages investment. For the market’s stability to improve existing manufacturers should establish supply chains within their region and implement innovative processing methods for raw materials.

Opportunity
