Scan to add us Our plant at No. 15 Tieyun Road, Huai'an Economic Development Zone, Jiangsu covers about 128,000 m² and runs sulphate-process anatase lines for fibre-grade TiO₂. A second 30,000 t/yr line for fibre-, food- and pharma-grade pigment was commissioned in August 2025, with centralised control and full process data capture.
From reactors and sand mills to automatic packing and palletising — one continuous train covers the whole post-treatment sequence.
The laboratory handles incoming raw materials, in-process control and finished-product release: TiO₂ content, moisture, pH, oil absorption, residue on sieve, brightness and chromaticity, particle-size distribution and dispersibility are all tested to standard methods. It also runs grade development and application trials: a pilot extruder on site lets a masterbatch or compound formulation be reproduced before you commit a production line.
We work with universities and research institutes on matting mechanisms, surface coating technology and application processing, and keep improving sulphate-process parameters for batch stability while building up food-grade, pharma-grade and chloride-process know-how.
Patents follow the process: the plant holds 29 granted patents (3 inventions, 26 utility models) covering fine grinding and sand milling, wetting and dispersion, filter pressing and vacuum filtration, drying and spray drying, pulping and conveying, packing and screening, plus wastewater and tail-gas treatment.

Ilmenite feedstock and sulphate-process parameters are checked at defined control points; crystal form, particle size and coating quality are verified in-line.
Each batch is released only after TiO₂ content, moisture, residue, oil absorption, pH, brightness and chromaticity are tested.
Bag-level lot numbers link every delivery to its test report and production record — traceable and explainable.
Packing list, invoice, certificate of origin, COA and SDS travel with your order and are pre-approved before despatch.
The plant is certified to ISO 9001 (quality), ISO 14001 (environment), ISO 45001 (occupational health & safety) and ISO 50001 (energy); see Certifications & IP for the issued certificates and their validity dates.
Environmental performance is designed into the process: by-product iron sulphate is recovered for resale, waste water and tail gas are treated and partly recycled, and the plant runs a carbon-and-energy improvement programme across all units.
