Zinc is the world's fourth most consumed metal, with approximately 12 million tonnes of mine production per year (zinc content), concentrated primarily in China (33%), Peru (11%), and Australia (9%). The metal's commercial identity is inseparable from its galvanizing function: roughly half of all zinc produced ends up as a sacrificial corrosion-protection coating on steel, exploiting zinc's electrochemical preference to corrode before the underlying iron. Galvanized steel is a foundational input for construction, automotive, and infrastructure.

Pricing in 2024 reflected tightening concentrate supply: the LME cash average for Special High Grade zinc was approximately $1.26/lb (~$2,778/tonne), down 5% from 2023, yet the International Lead and Zinc Study Group projected a 164,000-tonne production-consumption deficit as smelters faced limited concentrate availability. The North American SHG premium over LME narrowed in 2024 but remained elevated. US apparent consumption of refined zinc fell 11% to 820,000 tonnes in 2024e, while net import reliance on refined metal reached 73%. Canada supplied 59% of US refined zinc imports (2020–23 average), with Mexico and Korea also significant. US concentrate exports (primarily to Asia) made the US a net exporter of zinc in ore form despite relying heavily on imports for refined metal.

World reserves stand at 230 million tonnes — approximately 19 years of current production — and identified resources total approximately 1.9 billion tonnes, with additional undiscovered resources in polymetallic volcanic massive sulfide (VMS) and sediment-hosted (SEDEX) systems. Australia alone holds 28% of world reserves, reflecting the scale of the McArthur River and Mount Isa districts. Zinc is not on the US 2022 Critical Minerals List or EU CRMA lists, reflecting its broad geographic distribution, large resource base, and the absence of any single controlling supplier.
