China Zinc Smelters Hit as Processing Fees Plunge to Record Lows

Chinese zinc smelters are grappling with a worsening feedstock shortage that has driven processing fees to historic lows and wiped out profits. Treatment charges on imported zinc concentrate have slumped to minus $50 a ton, a record low in Fastmarkets data going back a decade. China produces about half the world's refined zinc, used primarily to galvanize steel, but relies heavily on imports of ore. The last time smelters faced negative fees was in 2024, which triggered output cuts to stem losses.

For traders, the collapse in processing fees signals acute tightness in the global zinc concentrate market. When smelters pay miners to take their ore, it reflects extreme scarcity of raw material. This dynamic typically supports refined zinc prices as supply constraints filter through the chain. However, it also raises the risk of smelter closures, which could further disrupt supply. Live commodities prices and charts on NowPrice show how the market is reacting to these developments, with zinc futures under pressure amid demand concerns.

Looking ahead, the key question is whether Chinese smelters will follow the 2024 playbook and announce production cuts. Any such move would likely tighten refined zinc supply and support prices. Traders will also watch for updates on mine supply from major producers and any policy response from Beijing to stabilize the domestic smelting industry. The next few weeks will be critical in determining the direction of the zinc market.
