| 1 | Legal identity and registration | Confirm the supplier’s registered legal name, address, business activity, tax status, and authorized signatory in the relevant jurisdiction. | Current business-registration extract, tax-registration document, official domain email, and bank-account name matching the legal entity. | Documents show different legal names, recently changed bank details, residential addresses, or pressure to pay a third party. | Proceed only when the contracting party, invoice issuer, and payment beneficiary are consistent or formally explained. |
| 2 | Material specification | Define whether the cargo is bare bright wire, insulated cable, mixed copper cable, or another grade. State copper content, insulation type, attachments, moisture tolerance, and contamination limits. | Written specification, representative photographs, sample approval, weight records, and an independent inspection or assay procedure. | Terms such as “high grade” or “pure copper” appear without measurable composition, yield, or contamination limits. | Make the specification an annex to the contract and link payment adjustments to measured results. |
| 3 | Copper content and recovery yield | Check copper percentage or recoverable-metal yield using a method suitable for cable scrap. Insulation, steel, aluminum, plugs, and moisture can materially reduce payable copper. | Pre-shipment sample results, scale tickets, laboratory report where appropriate, and an agreed independent inspection at loading or destination. | Only seller-selected photographs are provided, samples are not representative, or the contract has no tolerance and rejection mechanism. | Use a documented sampling plan and calculate the payable amount from verified net weight and agreed recovery or assay results. |
| 4 | Certification and management systems | If certifications are claimed, check the exact standard, certificate number, validity period, certified site, activities covered, and exclusions. ISO 9001 concerns quality management; ISO 14001 concerns environmental management. | Certificate issued by an appropriately accredited certification body, verified through the issuer’s public directory or written confirmation. | Expired certificates, missing site addresses, mismatched legal entities, altered PDFs, or certificates covering a different activity. | Treat certification as supporting evidence, not proof of material quality or legal export authority. |
| 5 | Environmental and recycling authorization | Determine whether local law requires a waste-collection, storage, treatment, recycling, or export permit. Confirm that the permit covers copper cable and the actual operating site. | Current permit, regulator-issued record, site address, permitted waste categories, capacity, and expiry date. | A general trading license is presented as an environmental permit, or the permit covers only non-waste metal products. | Match the material description and site address to the permit before signing a purchase contract. |
| 6 | International trade credentials | Verify the applicable importer or exporter registration, customs identification number, VAT or tax number, and authority to conduct cross-border trade in the relevant country. | Customs registration record, tax-authority verification, export authorization where required, and consistent information on commercial documents. | The supplier cannot identify the exporter of record, uses another entity’s registration, or refuses to provide customs details. | Identify the exporter of record, importer of record, and responsible customs broker before shipment. |
| 7 | HS classification and regulatory status | Copper waste and scrap is generally associated with HS heading 7404, but national tariff lines and treatment can vary. Confirm whether the cable is waste, a recyclable commodity, or a product under local law. | Written classification advice from the customs authority or qualified broker, product description, photographs, and destination-country import requirements. | The seller insists on a classification that reduces duties without technical justification or uses a vague description such as “metal goods.” | Obtain destination customs confirmation before dispatch; do not rely solely on the supplier’s tariff code. |
| 8 | Basel Convention and transboundary movement controls | Assess whether the shipment is classified as waste and whether contamination, hazardous components, or destination-country rules trigger notification, consent, or restrictions. Electronic and hazardous waste rules may apply to mixed cable streams. | Regulatory classification, prior written consent where required, movement documents, waste analysis, and confirmation from competent authorities. | No assessment of hazardous constituents, unclear final recovery facility, or instructions to describe waste as ordinary merchandise. | Do not load until both exporting and importing jurisdictions confirm the required procedure. |
| 9 | Contract, Incoterms, and payment protection | Specify the chosen Incoterms® 2020 rule and named place, title and risk transfer, freight responsibility, inspection point, claims period, currency, taxes, and payment milestones. | Signed sales contract, pro forma invoice, inspection clause, documentary payment terms, and clearly allocated freight and customs responsibilities. | Undefined delivery terms, full prepayment without safeguards, last-minute beneficiary changes, or no remedy for short weight or off-specification cargo. | Use staged payment, independent inspection, or documentary controls for new suppliers and high-value cargoes. |
| 10 | Shipment documents and traceability | Require consistent commercial and logistics records, including commercial invoice, packing list, transport document, certificate of origin where needed, weight tickets, inspection report, and permits. | Document set with matching legal names, quantities, container or seal numbers, dates, origin, destination, HS description, and declared net and gross weights. | Inconsistent weights, altered documents, missing seal details, unexplained transshipment, or documents issued by unrelated entities. | Release final payment only after document review and completion of the agreed inspection and customs requirements. |
