Steel Companies in Jiangsu, China (2026 Directory, 234 listed)

This directory includes 234 iron and steel enterprises in Jiangsu Province on record for 2026, covering ironmaking, steelmaking, rolling and supporting processing. The information is mainly compiled from publicly disclosed data from ecological environment departments such as environmental impact assessments, pollutant discharge permits, hazardous waste transfers, as well as business registration information from market regulation departments, after cross-verification and arranged by region and product category. It is suitable for steel buyers, scrap steel suppliers, equipment service providers, and industry researchers to consult, for preliminary screening of cooperation partners and understanding regional capacity distribution.

3. How to verify these companies

To verify the qualifications of an iron and steel enterprise, it is suggested to take the following steps: First, check on the Ministry of Ecology and Environment's 'National Pollutant Discharge Permit Management Information Platform' whether the enterprise has obtained a pollutant discharge permit, focusing on whether the management category is 'key management' and whether the permitted discharge volume stated in the copy matches the actual production scale; second, check the local ecological environment bureau's official website for environmental administrative penalty records in the past two years, and be cautious if there are unrectified exhaust gas exceedances or solid waste violations; third, verify the enterprise list announced by the Ministry of Industry and Information Technology under the 'Steel Industry Standard Conditions', combined with the capacity replacement plan of the Provincial Department of Industry and Information Technology, to confirm whether its capacity is compliant and whether it has been included in the scope of capacity reduction; fourth, check the enterprise credit report on the 'Credit China' website and pay attention to whether it has been listed as a dishonest judgment debtor; fifth, if scrap steel procurement is involved, also check whether its quality inspection system has passed ISO 9001 certification, and may refer to the metallurgical product physical quality certification list published by CISA (China Iron and Steel Association), but note that this is not mandatory.

4. What to watch out for

Procurement in the steel industry is prone to pitfalls. Here are a few reminders: First, be wary of 'white-label' traders who quote low prices without a steel mill agency agreement, making quality hard to guarantee; second, before purchasing, make sure to confirm the product execution standard (e.g., GB/T 1499.2-2018 rebar), and upon delivery, request a quality guarantee certificate and check the heat/lot number; third, don't just look at the listed price, ask clearly about tax and freight to avoid disputes during settlement; fourth, pay attention to the enterprise's environmental performance rating, which is published by the Provincial Department of Ecology and Environment; under heavy pollution weather, plants with low ratings may suspend production, affecting supply; fifth, when signing a contract, clearly state the quality objection period and testing methods to avoid having no basis in case of disputes.
