How Black Mass Pricing Works, and Who Actually Buys It

Black mass doesn't have a published price the way copper or aluminium does. It's priced off what's inside it — the lithium, nickel, cobalt and graphite an assay says is recoverable — not off a single quoted number you can look up. Anyone selling it for the first time usually asks the same question: why can't I just get a market price like I would for any other scrap metal? The short answer is that black mass isn't one commodity. It's a mixture, and the mixture is different every time.

It starts with an assay, not a price sheet

Black mass is the shredded, processed remains of lithium-ion batteries — whatever's left after a pack or module has been broken down and the casing, wiring and other non-battery material removed. What's left is a mixed powder containing lithium, nickel, cobalt, manganese and graphite in proportions that depend entirely on the chemistry of the cells that went in. NMC cells leave a very different mix than LFP cells, and even within NMC the nickel-to-cobalt ratio varies by manufacturer and model year.

That means the first step in any deal isn't a quote — it's a representative sample going to a lab for assay. The assay reports payable metal content, and that content is what actually gets priced, not the black mass as a bulk material.

How the price actually gets built

Once the assay is in hand, pricing works roughly the same way it does for most metal-bearing scrap: each payable metal is priced against a public benchmark (LME for nickel and cobalt, lithium against the relevant lithium carbonate or hydroxide index), a payable percentage is applied — refiners don't pay 100% of benchmark value, because they still have to process, refine and lose some material along the way — and treatment and refining charges are deducted for the cost of turning mixed black mass into battery-grade output.

The result is a price that moves with two things at once: benchmark metal prices, which shift daily, and the assay result, which is specific to that lot. Two shipments of black mass from the same seller can price differently if the cell chemistry mix shifts between them. This is also why a number quoted for someone else's shipment is close to useless as a reference point — it reflects a different assay against different benchmark prices on a different day.

Who's actually buying

The buy side is narrower than the sell side. Payable-metal pricing only works for a buyer who can actually extract those metals, which means refiners and recyclers running hydrometallurgical or pyrometallurgical processing — not general scrap dealers, and not most commodity traders. That's a smaller, more specialized list than it looks from the outside, and it's part of why sellers who go looking for a buyer on their own often end up talking to intermediaries who don't process the material themselves and are just re-selling the assay.

On the sell side: salvage operators, auto dismantlers, collision recyclers, fleet operators retiring EVs at scale, and cell manufacturing plants generating production scrap. Anyone shredding or dismantling lithium-ion material at volume is a potential source, whether or not they think of themselves as being in the battery-recycling business.

Where a broker actually helps

None of the mechanics above require a broker — a seller can commission their own assay and shop it directly to refiners. What a broker adds is on both ends of that process: getting the material in front of buyers who are actually equipped to process that specific chemistry mix rather than shopping it broadly and hoping, and, on the buy side, surfacing supply that isn't advertising itself as available. A salvage yard sitting on shredded material doesn't necessarily know which refiners are short of feedstock this quarter, and a refiner short of nickel-heavy black mass doesn't necessarily know which dismantlers are generating it.

That's the gap Empire Global Sourcing works: connecting operators generating black mass, end-of-life packs and production scrap with the refiners and recyclers who buy it, on a flat 3–4% commission of the closed deal value. Nothing upfront, no retainer, and nothing owed if a deal doesn't close.

We also broker end-of-life EV battery packs, second-life packs, non-ferrous scrap and refinery feedstock — the broader recycling side of the battery supply chain, not primary mined concentrate, which moves on long-term offtake agreements a broker adds nothing to. Packs and modules that haven't yet been shredded fall under Auto Components & EV Parts instead.
