Introduction
Trung Hai Nghe An Group is a Vietnamese industrial company based in Quy Hop, Nghe An Province, best known for mining and processing white marble and producing calcium carbonate (CaCO₃) powder and related mineral-based materials. Although it is not a plastics manufacturer in the narrow sense, its products are significant to the plastics value chain because calcium carbonate is widely used as a mineral filler and extender in plastics compounding, alongside applications in chemicals, construction materials, and other industrial sectors.
The company is commonly identified internationally as THNA Group and is listed on CHINAPLAS’s eMarketplace as an exhibitor in the plastics and rubber supply ecosystem. Available company listings indicate that it operates an integrated model spanning quarrying, processing, trading, and export, with a production base centered on the company’s marble resources in Nghe An.
History and Development
Trung Hai Nghe An Group JSC was incorporated on 15 June 2018 according to business registry sources, although trade directory listings also describe the company as established in 2007, suggesting earlier operating roots or predecessor activity before the current legal entity was registered. The company’s registered headquarters is in the 2nd floor of the Trung Hai Nghe An Building in Quy Hop, Nghe An.
Public company material states that THNA Group controls five white marble quarries with substantial reserves in Nghe An Province and a combined area of 117 hectares, supported by long-term licensing from Vietnam’s environmental and resource authorities. The company also presents itself as a long-standing supplier of raw materials to CaCO₃ plants in Nam Cam Industrial Zone, indicating that its development has been closely tied to Vietnam’s industrial mineral and downstream filler markets.
By 2024, third-party business data reported growth in sales and assets, suggesting continued expansion in the company’s industrial base and trading activity.
Business Operations and Segments
Trung Hai Nghe An Group operates as a mining, processing, and trading company with a diversified business profile that extends beyond minerals into several adjacent industrial categories in registry databases. In practice, the company is most closely associated with the following operational areas:
- White marble quarrying
- Calcium carbonate and stone powder processing
- Natural stone supply and trading
- Export-oriented mineral sales
- Supporting logistics and industrial distribution
Registry and trade listings also show a broader set of declared business lines, including mining support services and other industrial activities, while public-facing marketing materials emphasize mineral extraction and downstream processing rather than consumer plastics products.
Products and Technologies
The company’s principal product family is white marble-derived calcium carbonate, including ultrafine stone powder and industrial-grade mineral products. Trade and shipment data also associate the company with uncoated calcium carbonate, white powder, white marble, and related mineral shipments.
Key product and process characteristics indicated by public sources include:
- High-purity white marble feedstock
- Stable calcium content
- Processed CaCO₃ powder for industrial use
- Bulk mineral export shipments
- Integrated quarry-to-distribution production flow
Company and directory descriptions refer to a modern production line and a closed process covering raw material extraction, factory processing, transport, distribution, and export. While detailed equipment specifications are not publicly disclosed in the available sources, this kind of product profile generally implies crushing, grinding, classification, and packaging stages suitable for mineral filler markets.
Applications and End Markets
Trung Hai Nghe An Group serves several industrial end markets, with the strongest public evidence pointing to:
- Plastics and rubber
- Chemical processing
- Construction materials
- Natural stone and mineral distribution
- Export markets in Asia
The relevance to plastics lies primarily in the company’s calcium carbonate powder, which is commonly used in polymer compounding to reduce cost, improve stiffness, and adjust processing behavior. CHINAPLAS’s inclusion of the company within its plastics and rubber exhibitor ecosystem reflects this downstream linkage.
Shipment data suggest a substantial export orientation, with reported activity in India, as well as other destinations in Asia including China and Cambodia in broader trade datasets.
Global Presence and Market Position
Public trade directories describe THNA Group as active in both Vietnam and international markets. Export databases indicate that the company has shipped goods abroad to multiple buyers, including customers in India, which appears to be an important destination for its mineral products.
The company’s market position is shaped by two structural advantages:
- Access to large white marble reserves in Nghe An Province
- Proximity to industrial users and export channels for industrial minerals
Business listings frequently describe THNA Group as a major or reputable Vietnamese stone and calcium carbonate producer, but these descriptions are promotional in tone and are not independently quantified by market share data in the available sources.
Sustainability and Environmental Initiatives
As a quarrying and mineral-processing company, THNA Group operates in an industry that is closely associated with land use, resource extraction, energy consumption, and dust management. Public material indicates that its quarrying activities are licensed long term and tied to specified mineral areas, which is relevant to environmental governance in extraction industries.
No detailed sustainability report was identified in the available sources, so any assessment of the company’s environmental performance remains limited. Based on the nature of its business, the main environmental issues likely include:
- Responsible quarry management
- Resource efficiency in mineral processing
- Transport and logistics emissions
- Dust and particulate control
- Compliance with mining and environmental licensing requirements
Financial Performance and Economic Impact
Company-profile data from EMIS reported 500 employees in 2023, indicating a relatively substantial industrial workforce for a provincial mineral company. The same source reported 21.18% net sales revenue growth in 2024, a 12.68% increase in total assets, and a small improvement in net profit margin.
These figures suggest a business with meaningful local economic impact in Nghe An through:
- Employment
- Quarry and processing activity
- Export earnings
- Supplier and logistics demand
- Downstream industrial mineral supply
Because the detailed financial statements were not available in the source set, these figures should be treated as indicative rather than exhaustive.
Leadership and Corporate Governance
Registry and directory sources identify Nguyễn Trung Hải as the company’s legal representative and board chairman, and list additional management contacts including Nguyễn Hữu Thịnh in marketing or deputy management roles. The company is organized as a joint stock company, which typically indicates a corporate governance structure with a board and shareholder base.
Public-facing company material consistently links the business identity to the THNA Group brand and to the broader Trung Hai Nghe An industrial group structure.
Innovations and Future Outlook
THNA Group’s near-term outlook appears closely tied to demand for industrial minerals, especially calcium carbonate used in plastics compounding, construction products, and other bulk-material applications. The company’s quarry reserves, export orientation, and integrated processing model provide a base for scaling if it continues to invest in product consistency, logistics, and quality control.
Potential strategic priorities inferred from the available evidence include:
- Expanding value-added CaCO₃ grades
- Strengthening export market diversification
- Improving processing efficiency and product uniformity
- Deepening ties to plastics and polymer compounders
- Maintaining regulatory compliance in quarrying and environmental management
Summary
Trung Hai Nghe An Group is a Nghe An-based Vietnamese mineral company focused on white marble quarrying and calcium carbonate processing. Its importance to the plastics industry is indirect but substantial, since its mineral output fits the supply chain for plastics fillers and compounding materials.
