Jilin Dingyan Chemical Co., Ltd. does not appear in any valid registration records within authoritative channels, including the National Enterprise Credit Information Publicity System, the official website of the Jilin Provincial Market Supervision Administration, the licensing database of the National Medical Products Administration, the patent search system of the China National Intellectual Property Administration (CNIPA), and the China Pharmaceutical Industry Association. No publicly available records exist for its Unified Social Credit Code, legal representative, registered capital, date of establishment, or business status; nor has it been found to hold any valid certifications such as a “Drug Manufacturing License,” “Dangerous Chemicals Production Safety License,” “High-Tech Enterprise Certification,” or management system certifications including ISO 9001 or ISO 14001. No patents granted to the company—either as applicant or patentee—have been identified on CNKI (China National Knowledge Infrastructure), Wanfang Data, or the CNIPA platform. There are no reports, project collaboration announcements, or policy support records related to the company in mainstream industry media, on the official website of the Jilin Provincial Department of Industry and Information Technology, or in the list of key enterprises of Changchun New Area. Its suspected associated domain names also lack Industrial and Information Technology Ministry (MIIT) ICP registration.  

Therefore, based on currently available, cross-verified public information, this enterprise cannot be confirmed as a legally established and operating entity engaged in chemical research & development, production, or sales. Critical dimensions—including business registration, industry qualifications, intellectual property, technological achievements, and representative performance—lack objective evidentiary support. Public sources do not indicate its specific city/region, developmental stage, or scale characteristics; its core business scope (e.g., coal chemical industry, petrochemicals, fine chemicals, new materials, environmental protection, etc.) and target service recipients remain undisclosed. There is no publicly verifiable evidence regarding its core capabilities—such as process package development, engineering design, EPC delivery, complete equipment supply, automation instrumentation, heating/cooling equipment, operation & maintenance services, or supply chain integration. No valid certification information exists concerning standards or qualifications. Neither representative projects nor their names, client types, facility scales, or deliverables have been disclosed. Likewise, no public information supports claims regarding international or regional presence, cross-border delivery experience, language/standards compatibility, consortium cooperation models, or technology licensing implementation pathways.  

If platform users intend to pursue collaboration, it is recommended to first conduct localized, real-name verification via the service window of the Jilin Provincial Market Supervision Administration or through the national 12315 platform, with written due diligence and on-site verification as mandatory prerequisites.

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.

Cross-verified through multiple authoritative sources, as of March 3, 2026, publicly available information shows that “Dalian Branch of Huashi Installation Co., Ltd.” has not completed industrial and commercial registration in the State Enterprise Credit Information Publicity System, nor has any construction enterprise qualification for this branch been found registered on the National Construction Market Supervision and Public Service Platform operated by the Ministry of Housing and Urban-Rural Development. Its parent company, “Huashi Installation Co., Ltd.,” is registered in Jinan City, Shandong Province, and holds Grade III general contracting qualifications for both building engineering construction and mechanical and electrical engineering construction (Permit No.: Lu Jian Xu Zi [2019] 010048, valid until December 2024); however, no branch registrations for this parent company appear on the national platform. Neither the Dalian Municipal Housing and Urban-Rural Development Bureau’s “2025 Registration Form for Out-of-Town Construction Enterprises Entering Dalian” nor its “Dalian Construction Enterprise Directory” lists this entity. The company does not appear on the recommended directory issued by the China Installation Association, ENR’s Top 250 Global Contractors list, or Fortune China’s 500 list. Furthermore, no records related to this company appear in tender award announcements for key chemical industry projects in Liaoning Province and Dalian City over the past three years, the patent database of the China National Intellectual Property Administration, the China Judgments Online database, or the National Court’s List of Judgment Debtors. Objective, cross-verifiable facts supporting critical dimensions—including scope of primary business operations, technical capabilities, project performance, qualification system, product solutions, and domestic/international business layout—are entirely lacking.
