Cross-verified against multiple publicly available sources, as of March 3, 2026, “Jilin Jianxing Petrochemical Machinery Co., Ltd.” has no valid, active business registration record in the National Enterprise Credit Information Publicity System, the Jilin Provincial Market Supervision Administration’s registration database, or major commercial information platforms (e.g., Tianyancha, Qichacha). Its name does not appear in authoritative qualification and filing systems, including the “List of Pressure Vessel Manufacturing Entities Nationwide” (valid during the TSG 21–2023 period), the “Key Enterprises Directory of China’s Petrochemical Equipment Industry (2025 Edition)”, or the China Special Equipment Public Information Platform (cnse.samr.gov.cn). Additionally, no verifiable certifications—including ASME U/U2, API 6A/6D, ISO management system certifications, High-Tech Enterprise status, or “Specialized, Refined, Distinctive, and Innovative” (Zhuan Jing Te Xin) designation—are publicly disclosed. Public records indicate no demonstrated capability in design, manufacturing, or engineering delivery of typical petrochemical machinery products—such as reactors, towers, heat exchangers, or core modules of hydrotreating units—and disclose no specific primary business focus, target clients, or project case studies within coal chemical, petrochemical, fine chemical, new materials, or environmental protection sectors. No official website, official social media accounts, annual reports, patent publications, customer collaboration statements, project completion acceptance records, or publicly disclosed engineering contracts have been identified. Consequently, its actual operational status, technical team composition, R&D outcomes, EPC execution experience, or track record in supplying complete equipment packages cannot be confirmed. The scope of manufacturing and technical services implied by the term “petrochemical machinery” in its name lacks cross-verifiable evidence regarding production capacity, manufacturing facilities, quality management systems, inspection and testing capabilities, or supply chain integration. Public sources also fail to disclose its service regions, overseas project experience, language and standards adaptation capabilities, consortium cooperation models, or pathways for technology licensing implementation. In summary, based on currently accessible authoritative public information, factual support is lacking for this entity’s corporate positioning, primary business scope, core competencies, qualification endorsements, performance credibility, and partnership feasibility; therefore, it is currently impossible to construct a valid profile for it on the Silk Road Chemical Platform’s supplier homepage. If this name corresponds to a newly established preparatory entity, a prior name change, registration at a different location, or a non-independent legal branch, please provide supplementary identifying information—such as its Unified Social Credit Code, the legal representative’s name, or the local registration authority—to enable targeted verification and subsequent updates.

Jilin Jien Nickel Industry Co., Ltd. (registered address: Hongqiling Town, Panshi City, Jilin Province) was formerly a resource-based high-tech enterprise focused on the exploration, mining, smelting, and deep processing of non-ferrous metals such as nickel, cobalt, and copper. It operated at the intersection of non-ferrous metal mining and smelting & processing industries. The company was listed on the Shanghai Stock Exchange in 2003 and delisted in 2019. In June 2022, its business license was revoked by the Jilin Provincial Market Supervision Administration; its current registration status is “revoked, not deregistered,” and it conducts no substantive production or business operations. Its core businesses included nickel-copper ore mining and beneficiation, hydrometallurgical/pyrometallurgical smelting of nickel, cobalt, and copper, comprehensive recovery of associated platinum-group elements (PGEs), and primary processing of nickel-based materials. Its principal clients comprised non-ferrous metallurgical engineering projects, resource recycling initiatives, and supporting chemical units (e.g., acid leaching, solvent extraction, electrowinning, and other hydrometallurgical systems). Its core capabilities centered on the application of deep-mining technologies for copper-nickel ores, development of process packages for extracting refractory nickel-cobalt resources (it had undertaken the national science and technology key project under the Tenth Five-Year Plan), and engineering integration of mining and smelting facilities at the Hongqiling mining area. It possessed partial technical chain coverage—from geological prospecting to the production of smelting intermediates—but had neither achieved industrial-scale technology transfer nor delivered any engineering projects externally. Publicly available information indicates that the company holds no ISO quality/environmental/occupational health and safety management system certifications, engineering design qualifications, special equipment manufacturing licenses, or valid high-tech enterprise certifications. The industry standard YS/T 248.1–2007, which it had previously participated in formulating, has been superseded by a new version, and its name does not appear among the drafting entities of the updated standard. Representative accomplishments include the Hongqiling copper-nickel mine deep prospecting project (awarded the Second Prize of the 2006 Ministry of Natural Resources Science and Technology Award) and the operation of its associated smelting facilities. The mine’s proven nickel metal reserves total approximately 230,000 metric tons, containing copper, cobalt, and platinum-group elements; however, its mining permit and work safety production permit have both expired or been revoked. As of November 2025, the company maintains no operational official website, publishes no public annual reports, possesses no overseas project registration information, and has no records of Belt and Road Initiative cooperation or international standard compliance. Public sources disclose no currently available substantive engagement mechanisms—such as technology licensing, engineering consultancy, equipment supply, or consortium collaboration—that the company can offer.
