3. How to verify these companies

To verify the qualifications of a copper enterprise, follow these steps: 1. Check the pollutant discharge permit: Log in to the National Pollutant Discharge Permit Management Information Platform, enter the full name of the enterprise, verify whether the industry category includes "copper smelting" or "recycled copper", confirm that the permit is within its validity period, and compare whether the discharge outlets and permitted pollutant types are consistent with actual conditions. 2. Check environmental impact assessment procedures: On the official website of the Jiangsu Provincial Department of Ecology and Environment, under the "Administrative Approval" or "EIA Publicity" sections, search for the enterprise name or project name to confirm that new construction or renovation and expansion projects have obtained EIA approval and completed acceptance. 3. Check hazardous waste operating qualifications: If the enterprise is engaged in waste copper recycling and utilization or involves the disposal of hazardous waste (such as copper-containing sludge or waste acid), it must be searched in the hazardous waste operating permit list of the provincial Department of Ecology and Environment, noting the approved business scope and validity period of the permit. 4. Check enterprise credit: Query the enterprise's registration information, administrative penalty records, and abnormal operating status through the National Enterprise Credit Information Publicity System to confirm that its business scope includes copper-related business and that there are no major environmental penalties. 5. Check product inspection reports: Require the enterprise to provide a recent third-party test report for copper product composition, and verify key indicators such as copper grade and impurity content.

4. What to watch out for

When selecting copper product suppliers, attention should be paid to several common issues. First, copper prices fluctuate significantly, so long-term contracts need to specify the pricing method (e.g., referencing the Shanghai Futures Exchange copper price). Second, the quality of recycled copper varies greatly; be sure to inspect the goods and retain samples to prevent the inclusion of sediment or excessively high impurities. Third, pay attention to the enterprise's environmental compliance. If it is shut down for violations, supply will be delayed. Fourth, by-products such as copper slag and flue dust may be hazardous waste, so confirm that the enterprise has appropriate disposal qualifications to avoid joint liability. During on-site inspections, pay attention to production processes and inventory conditions, and ask for invoices and other vouchers from the past three months.
