3. How to verify these companies

The qualification of precious metals enterprises can be verified from the following aspects: First, log in to the official website of the Jiangsu Provincial Department of Ecology and Environment to check the enterprise's pollutant discharge permit, focusing on whether the licensed industry category, pollutant indicators, and heavy metal emission limits match. Second, verify on the 'National Pollutant Discharge Permit Management Information Platform' whether the enterprise has submitted its implementation reports on time; overdue or missing reports indicate non-standard management. Third, if the enterprise is involved in the collection and treatment of waste materials containing gold, silver, platinum, etc., it must be verified in the hazardous waste operation permit list published by the local ecological environment department, checking the approved operation category, scale, and validity period. Fourth, review the enterprise's environmental impact assessment acceptance documents to confirm that its processes and production capacity are consistent with the declared information. Fifth, you may require the enterprise to present its raw material procurement ledgers and product testing reports for the most recent six months, paying attention to verifying key metal content records.

4. What to watch out for

Precious metals transactions have high unit prices and small weights, making them prone to disputes over purity and weight. Before cooperation, be sure to agree on sampling and testing methods, and it is recommended that both parties jointly send samples to a third-party laboratory. Do not easily trust verbal quotes; rely on spectral testing or fire assay results. Shorten the payment cycle as much as possible and avoid long payment terms. At the same time, pay attention to whether the enterprise has formal environmental protection procedures. If it cannot provide waste transfer manifests or operates beyond its licensed scope, it may subsequently implicate customers in joint liability.
