Introduction
Qujing Zhongyi Fine Chemical Industry Co., Ltd. (曲靖众一精细化工股份有限公司) is a Chinese coal-tar deep-processing and carbon black manufacturer based in Qujing, Yunnan Province. Founded in 2006, the company is positioned as a private fine-chemical enterprise engaged in production, sales, and research and development, with a business profile centered on coal-tar oil processing, rubber carbon black, specialty carbon black, and related downstream coal-chemical intermediates.
The company’s reported operating footprint combines 250,000 metric tons per year of coal-tar oil deep processing with 130,000–150,000 metric tons per year of carbon black capacity, alongside a portfolio of more than 40 products spanning carbon black and coal-tar-derived chemical products. Its product mix and downstream orientation place it within the industrial chain that supplies rubber, plastics masterbatches, coatings, inks, and other pigment-intensive applications, linking it to both traditional carbon black markets and higher-value fine-chemical segments.
History and Development
Qujing Zhongyi Fine Chemical Industry Co., Ltd. was established in 2006 in the Yuezhou industrial area of Qujing. From the outset, the company developed around the utilization of local coal-tar resources and the integration of processing with product development and sales.
A second stage of development was the expansion of its downstream chemical chain through affiliated processing and synthesis operations. Industry and company materials identify a related entity, Qujing Zhongyi Synthetic Chemical Industry Co., Ltd., established in 2013, which further processes coal-tar products into higher-value derivatives such as pigment and naphthalene-based intermediates.
The company has also been recognized in official and industry records as a high-tech enterprise in Yunnan and as a key emissions-disclosure entity in Qujing, indicating both technological positioning and regulatory significance in the local industrial landscape.
Business Operations and Segments
The company’s operations are organized around two broad business areas:
- Coal-tar deep processing
- Carbon black manufacturing
Its coal-tar processing activity converts coal-tar oil into industrial intermediates and fine chemicals used further downstream in dyes, pigments, and related products. The carbon black segment produces both rubber carbon blacks and specialty carbon blacks, with product families reported to include grades such as N134, N220, N234, N330, N326, N375, N550, N660, and N774, as well as proprietary ZY-series specialty grades.
The company has also been described as serving export markets through associated trade functions in Chengdu, which appears to support international sales and customer service for its chemical product lines.
Products and Technologies
Qujing Zhongyi’s product range combines standard carbon black grades with specialty carbon black and coal-tar-derived intermediates.
Main product categories
- Carbon black
- Specialty carbon black
- Pigment and dye intermediates
- Coal-tar fine chemical products
Carbon black grades and uses
The company reports production of common rubber grades such as N220, N330, N326, N375, N550, N660, and N774, which are typically used to reinforce elastomers, adjust abrasion resistance, and modify processability in rubber compounds. The firm also markets specialty carbon black products, which are stated to be used in plastic masterbatches, paints, and inks, where particle characteristics, color strength, dispersion behavior, and thermal stability are important performance factors.
Coal-tar processing and downstream chemicals
Company and industry sources indicate capacity for downstream products including carbazole, 1-naphthol, 2-naphthol, alpha-naphthol, beta-naphthol, and pigment violet 23 (PV23) or related dioxazine violet products. These products are consistent with a coal-tar value chain that moves from primary processing into aromatic intermediates and colorants.
Technical and process emphasis
The company describes its model as one of deep processing and resource utilization, with development built on coal-tar feedstocks and successive upgrading into more specialized products. That industrial structure is characteristic of firms that compete on both scale and process integration, where consistent feedstock conversion and downstream synthesis determine product quality and cost position.
Applications and End Markets
Qujing Zhongyi’s products are used in several industrial end markets:
- Rubber and tires
- Plastic masterbatches
- Coatings and paints
- Printing inks
- Leather and related colorant applications
Its rubber carbon blacks are relevant to tire compounding and general rubber reinforcement, while specialty carbon blacks serve color and functional applications in plastics and coatings. PV23 and related pigment products are used in plastics and colorant applications where weather resistance and color permanence are valued.
Global Presence and Market Position
The company is headquartered in Qujing, Yunnan, with business and export functions also associated with Chengdu, Sichuan. Trade and marketplace listings indicate export-oriented activity across South America, Southeast Asia, the Middle East, East Asia, and Western Europe.
Industry listings and company materials present Qujing Zhongyi as a supplier of carbon black and related fine chemicals, with particular emphasis on specialty carbon black and carbon-tar-derived intermediates. Chinese industry materials also describe the company as a significant participant in the coal-tar deep-processing segment within Yunnan’s chemical industry.
Research and Development
The company identifies itself as active in R&D, and its recognition as a high-tech enterprise suggests an emphasis on technical upgrading and process development. Patent records also indicate company ownership in at least one process-related invention involving chemical reaction-rate improvement, consistent with an internal emphasis on process optimization.
R&D appears closely tied to the company’s strategy of extending the coal-tar chain into higher-value derivatives and specialty grades rather than relying solely on commodity carbon black output.
Sustainability and Environmental Initiatives
Qujing Zhongyi’s industrial model is based on coal-tar resource utilization, a form of materials recovery and upgrading that is often presented as a way to extract higher value from by-product streams. In that sense, the company’s business model is tied to the broader industrial practice of improving feedstock efficiency through deep processing.
At the same time, carbon black and coal-tar processing are energy- and emissions-intensive activities, and the company appears in official local reporting as a key pollutant-discharge entity in Qujing. It also holds an administrative safety-related permit in Yunnan’s public licensing records, reflecting the regulated nature of its operations.
Financial Performance and Economic Impact
The company’s public-facing materials describe a substantial industrial footprint, including a reported site area of 237 mu and capital above 1 billion yuan in some listings. It also reports a workforce of around 500 employees in several third-party supplier profiles.
As a manufacturer in a resource-processing region, Qujing Zhongyi contributes to local industrial employment and to the downstream supply of carbon black and coal-tar chemical intermediates used by rubber, plastics, and pigment manufacturers.
Quality Management and Certifications
Third-party supplier profiles identify ISO 9001, ISO 14001, and IATF 16949 certifications for the company. These certifications indicate formalized quality management, environmental management, and automotive-supply-chain quality practices, which are especially relevant for carbon black products used in tires and other engineered rubber applications.
Innovations and Future Outlook
Qujing Zhongyi’s future development is likely to remain tied to three industrial directions already visible in its business model:
- Higher-value coal-tar derivative development
- Expansion of specialty carbon black products
- Process optimization and deeper integration of the coal-tar chain
Its combination of coal-tar deep processing, specialty carbon black, and pigment intermediates places it in a segment of the plastics and chemicals ecosystem where competitive performance depends on feedstock control, conversion efficiency, product consistency, and compliance with tightening environmental expectations.
