Start with the physical-market failure.

Real demand is more than expressed interest. The requirement should connect to an economic end use, a knowable specification, procurement authority and a lawful payment path.

Supply must exist or be reasonably createable, and direct procurement must be failing for an identifiable reason that could support a defensible EQZW role.

Common constraints: concentration, qualification, specification mismatch, fragmentation, access, timing, finance or route design.

Real supply is more than material in place. Material, inventory, capacity or recoverable units must exist; ownership and control must be establishable; physical characteristics must be knowable; and a credible economic end use must exist.

A qualification or transformation pathway, logistics, documents and payment must be plausible. The market-access constraint must be specific.

A stockpile looking for a buyer is not automatically an EQZW opportunity.

The difficult middle may sit in aggregation, qualification, blending or upgrading, logistics economics, documents, risk allocation, payment mechanics, credit, jurisdiction, timing or processing.

Why is an economically rational physical transaction not already occurring, and is there a defensible role for EQZW in solving that?

EQZW looks for economically usable units of a material, not only conventional sources bearing that commodity's name.

That can include secondary streams, residues, by-products, scrap, intermediates or other recoverable contained material—only where transformation, specification, ownership, route, lawful handling and economics work across the whole chain.
