Starting from Teck Resources, we walked the supply graph hop by hop to the goods you buy and the companies you own. Each step is the engine’s reasoning, scored for confidence and cited where a source backs it.
First impact
Smelter SO2 off-gas (byproduct acid) →Shortage riskHecla’s production halt reduces smelter SO2 off-gas, which is a byproduct feed for sulfuric acid, so downstream sulfuric acid availability tightens.

Sulfuric acid →Prices easeSmelter SO2 off-gas (byproduct acid)
With sulfuric acid output reduced, demand for smelter off-gas feedstock softens, pressuring its value even though it is a critical input.

Lower sulfuric acid production also trims demand for elemental sulfur input, though substitution dynamics make this somewhat less certain.

Elemental Sulfur (from Oil/Gas Processing) →Prices riseElemental sulfur is a critical feedstock for fertilizer and crop-input production, so tighter sulfur supply pushes their costs higher.
74% confidenceElemental Sulfur (from Oil/Gas Processing) →Prices riseSulfuric acid is made from elemental sulfur, so a tighter sulfur market raises sulfuric acid input costs.
