The company is headquartered in Jiande, Zhejiang Province, and presents itself as a long-established specialty materials producer whose portfolio spans food-grade and industrial-grade calcium carbonate, high-specification lime products, and nano-scale functional powders for downstream processing industries.
The company’s profile places it within the wider plastics and polymer-additives ecosystem because active nano-calcium carbonate and related mineral fillers are used in plastics, rubber, inks, adhesives, and coatings to improve stiffness, processing behavior, and cost performance. Tianshi reports a long operating history, a provincial calcium carbonate research and development center, nearly 30 patent authorizations, more than 20 provincial new-product development projects since 2010, and ISO 9001 and ISO 22000 certifications, indicating a business model built around specialty mineral processing, quality control, and application-oriented product development. It also states that it was listed on China’s New Third Board in 2016 and has expanded through subsidiaries to support growth and diversification.
History and Development
Tianshi traces its origins to the Xianfeng period of the Qing dynasty, when the business reportedly began with lime production for agricultural and construction uses before evolving into a modern calcium materials manufacturer. This historical narrative is central to the company’s branding, as it links traditional lime processing with present-day specialty mineral technologies.
Key milestones reported by the company include:
- 2003: certification under ISO 9001 quality management systems.
- 2008–2009: recognition as a national high-tech enterprise and later service as a standards-related working-group unit in the inorganic chemicals sector, according to third-party supplier listings.
- 2015: certification under ISO 22000 food safety management systems.
- 2016: listing on the New Third Board in China.
The company also says it has established Zhejiang Tianyi New Materials Co., Ltd. and Guangxi Tianshi New Materials Co., Ltd. as subsidiaries to support sustainable development and capacity expansion. Its public materials further indicate a design capacity of 300,000 tons and an annual production capacity of 200,000 tons for series products, suggesting a mid-sized industrial footprint focused on specialized mineral grades rather than commodity bulk scale.
Business Operations and Segments
Tianshi’s core business is the production and sale of calcium-based inorganic materials, with a product mix that includes light calcium carbonate, heavy calcium carbonate, food-grade calcium carbonate, calcium hydroxide, calcium oxide, and active nano-calcium carbonate. The company also identifies toothpaste-grade calcium carbonate and high-surface-area calcium hydroxide among its specialty offerings.
Its operating model appears to combine:
- Mineral processing and refinement
- Application development for downstream industries
- Domestic manufacturing and export sales
- Standards participation and technical collaboration
The company reports 10 distributors worldwide and business relationships in more than 40 countries and regions, indicating an export-oriented sales structure supported by regional distribution. Public supplier directories also describe Tianshi as a core participant in China’s calcium carbonate cooperation network and a working-group leader in inorganic chemicals standardization, which reinforces its position as a technically specialized producer rather than a pure commodity supplier.
Products and Technologies
Tianshi’s product portfolio centers on precipitated calcium carbonate (PCC), light calcium carbonate, heavy calcium carbonate, calcium hydroxide, and calcium oxide, with variants tailored for food, toothpaste, and industrial use. The company emphasizes active nano-calcium carbonate, which is typically used as a functional filler where particle size control, surface activity, and dispersion behavior matter to end performance.
Its published materials indicate several concrete product categories:
- Industrial-grade precipitated calcium carbonate
- Food additive calcium carbonate
- Toothpaste industrial light calcium carbonate
- Industrial-grade calcium oxide
- High-end calcium hydroxide
- Active nano-calcium carbonate
From a plastics-industry perspective, the most relevant technology is its nano-calcium carbonate line. Mineral fillers of this type are commonly used to modify polymer stiffness, dimensional stability, surface finish, and processing economics, especially in compounds, masterbatches, and filled thermoplastics. While the company’s public materials do not disclose polymer-specific formulations, its own subsidiary description states that active nano-calcium carbonate is widely used in plastics, rubber, ink, paint, and adhesives.
The company states that it operates 7 automated production lines, which suggests an emphasis on controlled industrial processing and product consistency. It also reports quality and compliance certifications including TÜV/GS, CE, UL, ROHS, and PCT, alongside ISO-based management systems, indicating an export-facing product strategy with attention to regulated and specification-driven markets.
Applications and End Markets
Tianshi serves a broad range of industrial and consumer-facing sectors, including:
- Plastics
- Rubber
- Inks and coatings
- Adhesives
- Toothpaste and oral-care materials
- Food additives
- Pharmaceutical intermediates
- Environmental and industrial treatment uses
Its company materials highlight established supply relationships with major consumer-product groups such as Colgate, Procter & Gamble, and Nestlé, which suggests that at least part of its production is qualified for stringent quality-controlled applications. The company also states that its products are exported globally and used by customers in over 40 countries and regions.
For plastics manufacturers, the relevance lies mainly in functional mineral filler supply. Calcium carbonate is one of the most widely used fillers in polymers because it can reduce raw-material cost while improving rigidity and processability in many formulations, although the exact effect depends on particle size, coating, loading level, and resin system. Tianshi’s focus on nano- and light-calcium carbonate positions it in higher-specification segments of that market.
Global Presence and Market Position
Tianshi operates from Jiande, Zhejiang, with a commercial footprint that extends beyond China through distributors and export customers. The company’s marketing materials emphasize international sales, while third-party supplier listings and trade directories show that its products are circulated in global B2B channels.
Its market position appears strongest in specialty calcium carbonate rather than in broad commodity minerals. Public references describe it as a notable Chinese enterprise in the calcium carbonate industry and a participant in national standardization work. However, available public data do not support a precise global ranking or verified market-share figure, so it is more accurate to describe Tianshi as a specialized regional-to-international supplier with technical credibility in calcium-based powders.
Sustainability and Environmental Initiatives
Tianshi frames its development around the concept of using “gifted rocks from nature” to produce higher-value materials, which reflects a materials-efficiency narrative common in the mineral-additives sector. Its public emphasis on food-grade products, quality systems, and process automation suggests an effort to align production with tighter safety and consistency standards.
The company also reports the formation of subsidiaries and continued product development as part of a “sustainable development” strategy. In practical industry terms, calcium carbonate and lime producers face continuing pressure to manage energy use, emissions, dust control, and waste handling, but Tianshi’s publicly available materials do not provide detailed emissions or decarbonization metrics, so no specific environmental performance claims can be verified from the cited sources.
