Import and export data
According to customs data, the cumulative import volume of titanium dioxide from January to November 2022 is about 116200 tons, a decrease of 34.06% over the same period last year, and the import volume is about 60000 tons; It is estimated that the annual import volume will be 120000 tons, about 70000 tons less than last year. The domestic market demand is weak, and the import of titanium dioxide in China has declined significantly. The new capacity of domestic chlorinated titanium dioxide increased, and the high-end titanium dioxide imported from abroad decreased accordingly.
According to customs data, from January to November 2022, the total export volume of titanium dioxide was about 1279100 tons, an increase of 8.58% over the same period last year, and the export volume increased by about 101100 tons. The export market maintained a stable and rising trend, and the annual export volume is expected to be 1.38 million tons. The export situation in the first half of the year was better than that in the second half, and the overall export market maintained an increasing trend.
Capacity output
According to public data, the cumulative output of titanium dioxide from January to November 2022 is about 3.5755 million tons, up 3% over the same period of last year, with an increase of about 96400 tons, and the annual output is expected to be 3.9 million tons. The enterprises that have increased the output of titanium dioxide this year are mainly, an increase of 11%
The output growth rate was 2%. This year, the newly launched enterprises CITIC Titanium Industry, Yibin Tianyuan, Shengwei Fuquan and Xianghai Titanium Industry had a significant increase in output compared with last year, and the output of more than 20 small and medium-sized enterprises in the market decreased by different degrees compared with last year.
Downstream terminal
From January to November, the national real estate development investment was 12386.3 billion yuan, down 9.8% year on year; Among them, the residential investment was 9401.6 billion yuan, down 9.2%.
From January to November, the housing construction area of real estate development enterprises was 8968.57 million square meters, down 6.5% year on year. Among them, the residential construction area was 6339.16 million square meters, down 6.7%. The newly started housing area was 1116.32 million square meters, down 38.9%. Among them, the newly started residential area was 817.34 million square meters, down 39.5%. The completed housing area was 557.09 million square meters, down 19.0%. Among them, the completed residential area was 404.42 million square meters, down 18.4%.
From January to November, the sales area of commercial housing was 1212.5 million square meters, down 23.3% year on year, including the residential sales area, down 26.2%. The sales volume of commercial housing was 11864.8 billion yuan, down 26.6%, of which the sales volume of residential housing was down 28.4%.
At the end of November, the area of commercial housing for sale was 55.203 million square meters, with a year-on-year growth of 10.0%. Among them, the residential area for sale increased by 18.0%.
From January to November, the paid in capital of real estate development enterprises was 13631.3 billion yuan, down 25.7% year on year. Among them, domestic loans amounted to 1582.3 billion yuan, down 26.9%; The utilization of foreign capital was 6.6 billion yuan, down 26.6%; Self raised funds amounted to 4899.4 billion yuan, down 17.5%; Deposit and advance receipts amounted to 4460.1 billion yuan, down 33.6%; Personal mortgage loans reached 2187 billion yuan, down 26.2%.
On the whole, affected by the economic pressure this year, the sales volume of real estate has gradually declined this year, and the national infrastructure investment index has also continued to decline. The demand growth of the downstream coating industry will slow down. At present, the purchase restriction policy of real estate has been cancelled, and in November, a trillion yuan of large state-owned banks rushed to help the real estate industry, which is good for the current market to a certain extent.
3. Future market forecast
According to the titanium dioxide analysts from the Chemical Branch of the Business Cooperative, the market price of titanium dioxide will fall sharply in 2022. Affected by the economic situation, the domestic market will be light, but the export market will remain good. The introduction of various favorable policies for real estate before the year will benefit the titanium dioxide market to some extent. It is expected that the titanium dioxide market will mainly maintain stable operation in the short term.
For research published in 2022 study in the journal Food and Chemical Toxicology, scientists examined “the genotoxicity and the intracellular reactive oxygen species induction by physiologically relevant concentrations of three different TiO2 nanomaterials in Caco-2 and HT29-MTX-E12 intestinal cells, while considering the potential influence of the digestion process in the NMs’ physiochemical characteristics.” They found a “DNA-damaging effect dependent on the nanomaterial,” along with the micronucleus assay suggesting “effects on chromosomal integrity, an indicator of cancer risk, in the HT29-MTX-E12 cells, for all the tested TiO2 nanomaterials.” Researchers concluded that the results showcase “evidence of concern” regarding titanium dioxide used as a food additive.
Scrap zinc or concentrated zinc ores are dissolved in sulfuric acid, the solution is purified and the two solutions are reacted. A heavy mixed precipitate results that is 28 to 30% zinc sulfide and 72 to 70% barium sulfate.
Titanium dioxide (TiO2) is a versatile and widely used inorganic compound that has numerous applications, ranging from pigments in paints and coatings to cosmetics and pharmaceuticals. As a result, the demand for TiO2 powder suppliers has been steadily increasing.

Recent analyses of food-grade TiO2 samples have found that a significant portion of particles may be within the nanoscale. These particles (also known as nanoparticles) range in size from 1 to 100 nm, where 1 nm equals 1 billionth of a metre (the width of a typical human hair is 80,000 to 100,000 nm).
Gravimetric analysis is a method of quantitative chemical analysis in which a substance is converted into a stable compound of known composition, and the mass of this compound is then measured. This technique offers a high level of precision and is particularly useful in determining the concentration of materials within complex mixtures. The gravimetric determination of titanium dioxide typically involves a series of well-defined steps, which include precipitation, filtration, washing, drying, and weighing.
zinc sulfide content, %
China’s government is working on its plan to eliminate outmoded capacities of TiO2 and strengthen environmental protection measurements. Small and middle-sized enterprises, with a production capacity under 50,000t/a, are the ones to suffer. They mostly get merged or need to withdraw from the market. Without their production capacity of about 500,000 tonnes yearly, the domestic output might shrink about 20%. This will enhance the power of listed companies in China immensely, which is one of the main reasons for the effort to go public.
This route affords a product that is 29.4 wt % ZnS and 70.6 wt % BaSO4. Variations exist, for example, more ZnS-rich materials are produced when zinc chloride is added to the mixture of zinc sulfate and barium sulfide.[1]
The main food categories contributing to dietary exposure of E171 are fine bakery wares, soups, broths and sauces (for infants, toddlers and adolescents); and soups, broths, sauces, salads and savoury based sandwich spreads (for children, adults and the elderly). Processed nuts are also a main contributing food category for adults and the elderly.
In addition to pigments and sunscreens, titanium dioxide is also used in the production of paper, food products, and pharmaceuticals. In the paper industry, titanium dioxide is added to paper coatings to improve brightness, smoothness, and printability. In the food industry, titanium dioxide is used as a whitening agent in products such as candies, chewing gum, and icing. In the pharmaceutical industry, titanium dioxide is used as a coloring agent in tablets and capsules.

In summary, the Food Directorate's position is that there is no conclusive scientific evidence that the food additive TiO2 is a concern for human health. This is based on a review of the available scientific data relevant to food uses of TiO2. However, we will continue to monitor the emerging science on the safety of TiO2 as a food additive and may revisit our position if new scientific information becomes available.
