Commercial definition

Clean unalloyed copper solids, clippings, punchings, commutator segments or tubing prepared to an agreed high-recovery standard.

Important: The grade name does not override the contract. Counterparties should attach a written specification and agree how compliance will be assessed.

Specification framework

ParameterCommercial expectation
Metal / recovery basisHigh copper recovery; exact chemistry and preparation by contract
MoistureDry unless otherwise agreed
ContaminationTightly restricted attachments, solder, paint, scale and non-copper material
Not permitted unless agreedClosed vessels, hazardous residues, excessive solder, brass or aluminium mixing
PackagingLoose, boxed, baled or bundled

Inspection priorities

Check alloy identity, soldered joints, plating, iron attachments, sealed units, oil and hidden mixed grades.

  • 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

Loose, boxed, baled or bundled. 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: 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.
