Nickel Companies in Jiangsu, China (2026 Directory, 135 listed)

This directory includes a total of 135 nickel-related recycling, processing, and utilization and disposal enterprises in Jiangsu Province, covering the utilization and disposal stages of nickel-containing waste such as nickel-bearing scrap recycling, nickel-based alloy and stainless steel processing, electroplating sludge, and spent catalysts. The included information has been compiled from public channels, including the pollutant discharge permit information disclosure platform, hazardous waste operating permit announcements, construction project environmental impact assessment (EIA) and acceptance announcements, and enterprise credit information disclosures, etc.; it does not include self-reported production capacity or quotations from enterprises. It is suitable for recyclable metal buyers, traders, downstream material-using enterprises, and peers responsible for solid waste compliance to conduct preliminary due diligence; specific information shall still be subject to the latest official announcements and on-site verification.

"Verifiable" = a unified social credit code for this company can be found in public Chinese registries. The full list of 135 companies is at https://www.guilinmetals.com/en/companies.

3. How to verify these companies

First, check the hazardous waste operating permit: verify it in the permit announcement section on the official website of the provincial Department of Ecology and Environment, focusing on confirming whether the approved categories cover the waste codes you are actually involved in (such as HW17 surface treatment waste, HW46 nickel-containing waste, etc.), and whether the approved operating scale and validity period match your volume. Second, check the pollutant discharge permit: query the National Pollutant Discharge Permit Management Information Platform to verify the industry category, permitted discharge amount, and whether it is within the validity period. Third, check the EIA and acceptance: check the project acceptance, approval, and acceptance announcements on the website of the local Ecology and Environment Bureau to confirm that the raw materials, process, and products match. Fourth, check enterprise credit: check the business scope, business abnormalities, and administrative penalty records on the National Enterprise Credit Information Publicity System. Fifth, commission a third party to sample and test each batch of goods, measure nickel content, moisture, and impurities separately, and agree in writing in advance on the sampling and sample preparation methods.

4. What to watch out for

Nickel-containing scrap is mostly priced at a discount based on nickel content; the pitfalls mainly lie in sampling and pricing basis: moisture deduction, distinction between metallic nickel and total nickel, and penalties for excessive impurities must all be written into the contract. The forms vary greatly (sludge, catalysts, offcuts, alloy turnings), and grade fluctuates significantly between batches; a single assay result cannot be applied to the entire batch. Cross-provincial transfers must go through hazardous waste approval. The risks of receiving goods without a permit and of documents not matching the goods ultimately fall on the waste generator; be sure to verify that the receiving party's permitted scope is consistent with the actual material.
