Sales and market prospects:
Since the beginning of this year, the theme of product price increase has been running through the domestic market. Grain, medicine, crude oil and chemicals are all rising wildly, with chemicals leading the rise, among which sulfur is the king of chemical price increase! The price of sulfur rose from the mainstream price per ton of 800 yuan in early 2007 to about 5,800 yuan at present, with an increase of 600% ~ 700%, which led to the increase of all chemical products by more than five times year-on-year, and was the highest price of chemical products in 2008, which surprised the industry. Experts pointed out that sulfur and its downstream product sulfuric acid have entered the industrial boom cycle, but with the gradual release of new sulfur production capacity in China, this high price may not last until next year. In 2009, natural gas purification in Sichuan will probably produce 4-5 million tons of sulfur. In addition, due to the current good production and sales situation, some small sulfur enterprises may resume production, which may increase the production capacity by about 3 million tons. These two items alone will increase domestic supply by about 8 million tons. However, it is uncertain whether the natural gas purification and release capacity will be in place in time. At present, the price increase of sulfur and sulfuric acid is nothing more than oil and gas desulfurization, nonferrous metal smelting, thermal power desulfurization and other industries. Although sulfur is only a by-product of these companies, this "unexpected surprise" is not small under the amazing increase, but the soaring price of sulfur has made its downstream industries complain, which is really a joy for several families. At the same time, the rising prices of agricultural products have doomed the development of global agriculture in the past two years, which has promoted the strong global demand for chemical fertilizers. One of the effects of fertilizer enterprises' expansion of production capacity is that the supply of raw materials for fertilizer production is tight, and sulfur has become an eye-catching star of price increase at this time.
In June, the average international crude oil price will continue to rise. In May, the international crude oil price has reached 127 USD/barrel. Judging from the current continuous upward trend, the price of crude oil in June is likely to reach 130 USD/barrel or even higher. At the same time, the prices of coal and natural gas will continue to rise. The rising energy cost is the main reason for pushing up the price of sulfur and sulfuric acid. As the international energy price is still on the rise, and June is the peak season of domestic fertilizer demand, the rapidly growing fertilizer industry will still increase the demand for sulfur and sulfuric acid, which may become the driving force to continue to push up the market price of sulfuric acid. In May, the highest ex-factory price of sulfur in some parts of China has approached 6000 yuan /t, and it is expected that the ex-factory price of sulfur in China will be further advanced to 6000 yuan /t on the basis of May. According to the current market situation, sulfur is likely to continue to rise in June, and the price in some places has exceeded the 6000 yuan /t mark. On June 3rd, solid sulfur with purity of 99.5% was quoted by Liaohe Petrochemical Company, Qilu Petrochemical Company and Anqing Petrochemical Company as 5800 yuan /t, 5900 yuan /t and 5950 yuan /t respectively. Solid sulfur with purity of 99.9% is quoted by Tianjin Petrochemical Company, Yanshan Petrochemical Company and Cangzhou Refinery as 6000 yuan /t, 6 100 yuan /t and 6 100 yuan /t respectively. The insiders believe that the market price of sulfur is likely to continue to climb in June, and the domestic ex-factory price of sulfur is likely to exceed 6,000 yuan/ton.
In fact, since the rapid increase of sulfur price in June of last year (5438+065438+ 10), its rising pace has never stopped, even worse. Some domestic phosphate fertilizer enterprises have limited production or stopped production due to excessive cost pressure. A few days ago, the General Administration of Customs issued Announcement No.35, 2008: With the approval of the State Council, sulfur import value-added tax will be exempted from May 20, 2008. The relevant units can enjoy the above-mentioned preferential policies of value-added tax in the import link without applying for tax exemption examination and approval from the customs in advance, and directly declare the import to the customs. At this moment, it is undoubtedly a gratifying news for relevant fertilizer enterprises to introduce preferential policies to exempt sulfur import value-added tax. According to incomplete statistics, enterprises can reduce the production cost of products by 50 yuan /t on average after reducing or exempting the value-added tax.
In order to ensure the safety of the Olympic Games, China announced that from May 1 day to August 3 1 day, it was forbidden to import bagged sulfur from Kazakhstan by railway through Alashankou Bank in Xinjiang. If this ban is implemented, it will further aggravate the shortage of market supply. It remains to be seen what will happen to the sulfur market after losing this large import supply source. The insiders admit that for China, which has been highly dependent on imported sulfur for a long time, sulfur has gradually become an important strategic material, which is not only related to chemical fertilizers and agricultural materials, but also widely used in rubber, paper-making, medicine, matches, pesticides, bleach and other industrial fields. Sulfur import must be carried out in an orderly and standardized manner. For most enterprises, it is very dangerous to blindly expand or build a sulfuric acid plant with sulfur as raw material at present and bet all the "treasures" on imported sulfur. When the price of sulfur is so high, if the downstream products do not have enough price-raising ability and market competitiveness, the pressure on enterprises is really great, and the state will take macro-control measures one after another. It is expected that the phenomenon that the price of sulfur is so high will not last long.
In 2008, the growth of world sulfur production mainly came from Canada, the Middle East, Kazakhstan and other countries and regions, about 36.5438+million tons, but the increase of output does not mean the increase of trade volume. For example, the amount of sulfur recovered from Canadian oil sands has increased, but due to transportation and granulation problems, the export volume will decrease by 500 thousand tons in 2008. Saudi Arabia will also reduce its export volume due to equipment problems, and Kazakhstan is still difficult to increase its foreign trade volume due to transportation problems. In 2008, the growth of sulfur international trade is limited, and it is estimated that the sulfur increment will be about 2 million tons. Due to the commissioning of some new fertilizer plants in China, Morocco and India, sulfur consumption will increase by about 2.4 million tons. Australian, Turkish, China and other non-ferrous metals will increase sulfur consumption by about 800,000 t, so the global sulfur supply is relatively insufficient, and the gap between supply and demand is still large. 2008 will be the most tense year of sulfur supply and demand, and sulfur, the king of chemical price increase, will continue to be crazy!
