Find the role your material needs.

A company can hold several roles. Distinguish source-stated activity from current capacity and lot-specific commercial acceptance.

Collector / recycler
Aggregates or recovers materials. Ask about permitted input, collection geography and the downstream route.
Processor
Sorts, prepares or transforms material. Confirm the equipment, contamination limits and output form.
Trader
Connects a commercial supply and buying route. Establish which party takes title, tests material and carries the contractual obligation.
Smelter / refiner
Processes suitable metal-bearing feedstock. Input analysis, lot acceptance and delivery conditions require direct confirmation.
Industrial buyer
Uses a defined material input. A product or plant description alone does not establish an open purchasing requirement.
