Commercial definition
Mechanically separated copper particles produced from cable or other feedstock and traded on metal content, particle size and residual contamination.
Specification framework
| Parameter | Commercial expectation |
|---|---|
| Metal / recovery basis | Usually high recovery; assay or agreed test basis recommended |
| Moisture | Low and controlled |
| Contamination | Residual plastic, aluminium, iron, fines and dust |
| Not permitted unless agreed | Wet product, excessive fines, mixed metals or inconsistent bags |
| Packaging | Jumbo bags, lined bags or drums |
Inspection priorities
Take representative samples from multiple bags or depths; check segregation, fines, moisture and metallic contamination.
- Verify stock identity and ownership before relying on photographs or video.
- Use representative sampling rather than inspecting only the visible outer layer.
- Record gross, tare and net weight basis and reconcile it with shipping documents.
- Agree the claims procedure, notification period and testing method before shipment.
Packing and loading
Jumbo bags, lined bags or drums. Container suitability, floor loading, securing, bale or bundle dimensions, seal control and photographic evidence should be considered before dispatch.
Commercial considerations
Pricing is influenced by recoverable metal, reference-market movements, processing cost, contamination risk, freight, financing, destination requirements and the timing mechanism in the contract. A large headline discount can be misleading when the specification or payment risk is weak.
Typical end uses: Copper remelting and refining
Frequently asked questions
Is the stated purity guaranteed by the grade name?
No. The grade name is commercial shorthand. Purity or recovery must be supported by an agreed specification, representative evidence and the contractual inspection method.
Can moisture and contamination simply be deducted at destination?
Only if the contract defines how they are measured, the acceptable limits, the independent party or laboratory, and the settlement formula.
Is third-party inspection sufficient on its own?
Inspection can reduce risk but does not replace counterparty due diligence, secure payment terms, document verification and clear title to the material.
