Zinc Companies in Jiangsu, China (2026 Directory, 121 listed)

This directory contains 121 zinc-related registered enterprises in Jiangsu Province, covering recycled zinc smelting, zinc alloy production, hot-dip galvanizing and die-casting processing, and zinc-bearing waste collection and disposal, among other segments. Information is drawn mainly from the integration of public channels such as pollutant discharge permit and hazardous waste operating permit disclosures, solid waste management information system records, and market regulatory registration information; it is compiled by available data fields with no on-site visits. It is suitable for buyers purchasing zinc alloy ingots, recycled zinc and zinc-based materials, waste generators seeking channels for zinc-bearing waste disposal, and practitioners doing preliminary supplier screening and regional peer benchmarking. The directory only answers which enterprises exist and what the public information is; it does not assess actual capacity, quality levels or operating conditions, and independent verification is still required before cooperation.

3. How to verify these companies

1. Hazardous waste operating permit: zinc slag, zinc ash and zinc-bearing sludge are mostly managed as hazardous waste, and the disposal party must hold a permit for the corresponding waste category and code. Search by name in the list of permit holders published by the provincial department of ecology and environment, and check the approved category, waste code, approved scale and validity period. 2. Pollutant discharge permit: search by name or unified social credit code on the National Pollutant Discharge Permit Management Information Platform, and check whether the industry category matches zinc smelting, die-casting or hot-dip galvanizing, and whether the permit is within its validity period. 3. Entity information: check the full name, code and business scope on the National Enterprise Credit Information Publicity System; note that a "renewable resource recycling" qualification does not equal the ability to dispose of hazardous waste. 4. Quality documents: request the composition report for the zinc alloy grade, compare the grade and impurity limits against standards such as GB/T 13818, check lead, cadmium, iron and copper content and batch-to-batch consistency, and if necessary send samples for third-party retesting. 5. Transfer manifest: hazardous waste transfers use electronic manifests; check whether the waste name, code and quantity match the actual delivery.

4. What to watch out for

Zinc prices move with SHFE zinc and LME; when asking for quotes, clarify whether it is a processing fee or a zinc price premium, and which exchange and which point in time the pricing is based on. Where recyclable material is settled on metal content, agree on the sampling method and assay basis first; materials with high moisture or chlorine content are discounted significantly at the smelter. Lead, cadmium and iron out of spec in recycled zinc show up directly as defects in die-castings, so don't just look at the grade. Also note that having a recycling qualification does not necessarily mean being able to dispose of zinc-bearing hazardous waste; distinguish between transit traders and actual processing plants.
