Copper granules (also called nodules) are produced by chopping or shredding copper wire and cable and separating the copper from insulation. They are graded by purity: No. 1 nodules from bare wire and No. 2 nodules from No. 2 wire.

Grade definition — Clove / Cobra

Clove: No. 1 bare copper wire nodules, chopped or shredded, free of other metals, insulation and foreign material, minimum 99% copper. Cobra: No. 2 copper wire nodules, minimum 97% copper, with metal impurities not over 0.50% aluminium and 1% each of other metals or insulation.

Packaging and container loading

Packaging methodTo be confirmed at quotation
Estimated net weight per 20FT container22 metric tons (22,000 kg)
Estimated net weight per 40FT container28 metric tons (28,000 kg)
Price and availabilityQuoted per inquiry — no stock is implied by this listing

Estimated loading quantities — subject to the material's packing density, the actual container payload and applicable transport weight limits.

Inspection and quality verification

Grade, weight and contamination are checked before loading by visual inspection. Where the contract specifies it, an independent pre-shipment inspection (for example by SGS, Bureau Veritas or Intertek) and laboratory analysis — electrolytic assay for copper, XRF/OES analysis for alloys — can be agreed. Loading photographs and weighbridge tickets are normally part of the shipping documents. The inspection agency, sampling method and acceptance criteria are fixed in the contract.

Import compliance

Imports of metal scrap are regulated in many countries (import licences, pre-shipment inspection certificates, radiation checks). Buyers are responsible for confirming that the grade may be imported at the destination before contracting.
