Lead scrap availability -- the feedstock for secondary lead smelters that produce roughly 60% of the world's refined lead -- remains tight across major markets. US battery collection rates are estimated at roughly 95%, below the 98% target that would balance the secondary market. In Europe and parts of Asia, scrap flows are similarly constrained.
The tight scrap market is reflected in elevated scrap premiums over LME lead. Secondary smelters are paying premiums of $180-220 per metric ton for clean battery scrap, up from $120-150 a year ago. These higher input costs are being passed through to refined lead premiums, contributing to the physical market tightness that underpins LME prices.
The scrap supply constraint is partly structural. Lead-acid battery lifetimes have been extending as battery technology improves, meaning fewer batteries reach end-of-life each year relative to the growing vehicle fleet. At the same time, collection infrastructure in developing markets hasn't kept pace with rising vehicle ownership, leaving a growing volume of used batteries outside formal recycling channels.
The tight secondary supply is forcing more reliance on primary lead production from mines. But primary lead mine output has been growing slowly -- roughly 1-2% annually -- constrained by limited new mine development and grade declines at aging operations. The combination of constrained primary supply and tight scrap means the refined lead market is structurally tight.
The scrap tightness is a structural issue, not a cyclical one. Secondary smelters can’t simply ramp up when scrap isn’t available. For lead-acid battery manufacturers — the largest lead consumers — this means lead supply will remain tight for the foreseeable future. Building longer-term supply relationships with both primary and secondary producers is essential. The days of abundant, cheap scrap-based lead may be over.
