Last year, listed companies involved in purchasing and storage of rare earth authoritative sources , this earth is not yet officially started purchasing and storage company yet to receive notice of , " purchasing and storage generally only for state-owned enterprises , purchasing and storage price is basically a reference to the previous months the average price . "

The sources, purchasing and storage is scheduled Rare allow companies to bid , but only state-owned enterprises purchasing and storage , there are strict procedures and standards , " purchasing and storage are generally stable prices when purchasing and storage , the highest it will not purchasing and storage , the state may also be thrown out at the appropriate time . "

Earlier, experts said Chamber of Commerce , RE state purchasing and storage time and conditions are specific state secrets , the public will not be published . He further said that the earth will certainly be favorable purchasing and storage of raw materials involved in purchasing and storage enterprises, indirectly, would be favorable throughout the upstream rare earth industry .

For the rare-earth prices , the source said, purchasing and storage will support the prices of rare earth , while the earth as a strategic resource , the future price will be higher and higher, because the South will be less and less of heavy rare earths , and the current is limited to technology, marine rare earth the cost is too high .

According to public reports, in 2012 the price of purchasing and storage of rare earth allegedly by six months the average price of the acquisition . According to statistics, in 2013 the average price of rare earth 1-9 months : praseodymium neodymium 312,000 yuan / ton ; praseodymium 398,000 yuan / ton ; neodymia 313,000 yuan / ton ; europium oxide 4582000 / ton ; terbium oxide 3,667,000 yuan / ton ; dysprosium 1,938,000 yuan / ton ; erbium oxide 299,000 yuan / ton ; yttria 79,000 yuan / ton.

Recently, there are reports that state purchasing and storage plan will be ten billion rare earth opened in October , but the Chinese Society of Rare Earths , deputy head Xu Guangyao expert told reporters : "It was conducted in June and July to purchasing and storage , but has not settled purchasing and storage which varieties to what price , what companies involved are not yet finalized, but also, and relevant units to bargain , but the purchasing and storage of the relevant work has been carried out . "

According to Xu Guangyao , the previous work on purchasing and storage of rare earth once pushed to the second year around the Spring Festival began , "can be carried out in October purchasing and storage , but also the progress of the work . "

Baotou Steel Rare Earth insider told reporters: " Rare-Earth International Trade Company has not received the following specific purchasing and storage implementation. I want to feel with the completion and rare earth trading platform . "

Rare earth business people said that no matter how purchasing and storage operation, beneficiaries are always big business.

Shouchu boost confidence

Serious oversupply

Rare insiders generally believe that the current oversupply situation rare earth industry is more serious , rare earth enterprises purchasing and storage to let some gain , boost market confidence about .

Xu Guangyao told reporters that at present a large product inventory of rare earth , according to his estimates, the current inventory is equivalent to an annual yield ( program volume ) at 10 million tons.

Su Bo, vice minister of the Ministry of Industry on April 21 this year, held " China Rare Earth Industry Association Conference," said the 2012 plan 93,800 tons of rare earth minerals ( rare earth oxides ) , the actual production of 76,000 tons ; rare earth smelting and separation products plan 90,400 tons , the actual production of 82,000 tons . Does not include illegal production.

China is a big country of rare earth resources , accounting for 23 percent of the world total , but it took more than 90% of the world market supply . The current global production capacity of rare earth minerals , including private , including about 20 to 30 million tons, while global demand for rare earths is more than ten million tons, far higher than the supply demand .

Wind statistics show , rare earth permanent magnet plate 32 listed companies in the first half of this year, the total profit of 2.556 billion yuan , with 2012 profit of 4.846 billion yuan over the same period dropped 47 percent compared ; while adding to the inventory of excess capacity slow , leading listed company receivables rose three percent.

32 listed companies in the rare earth sector , 5 losses , 27 remain profitable , but the general decline in earnings . According to Wind statistics, 32 first-half revenues of 123.55 billion yuan , an increase of only 1.4% ; net profit of 2.556 billion yuan , down 47%.

China Nonferrous Metals Association, said Chen Quan training , rare earth overcapacity more serious, less than 40% capacity utilization . China Rare Earth Association, Gan Yong said that at present , China's rare earth permanent magnet materials production capacity of 300,000 tons , annual output of 80,000 tons , less than 30% capacity utilization .

There are rare earth companies told reporters that the surplus , to look at two aspects , those of large enterprises , financial strength, is gradually build the industrial chain , the surplus did not affect them . Those small businesses and private mines , the situation is not a time , started a month , discontinued six months are possible, they have been very cautious , and the impact of excess is acceptable . More should be referring to excess capacity planning is excess .

Purchasing and storage into a money-making tools

The rare earth enterprises , told reporters , rare earth market is not good , the state will pay the big companies will make money, not lose money , and the purchasing and storage price is higher than the market price.

Some analysts have said that last year purchasing and storage , the state selected several rare earth enterprises , invite several companies to acquire the amount and price of rare earth to bid , after the bidding companies to collect rare and self- preservation, followed by the government through cash back way , payment for purchasing and storage of products . Since the implementation of reserve side in the enterprise , leading to purchasing and storage enterprises to participate in the process of purchasing and storage revenue is very impressive.

It has been reported that the first quarter of this year, Baotou Steel Rare Earth attributable to shareholders of listed companies net profit of only $ 245 million in the second quarter , but the downturn in the industry counterattack was 805 million yuan , respectively, year on year and up 122% qoq and 229% . Gold analysts believe that this is the company recognized in the second quarter of last year, state purchasing and storage of rare earth gains.

After a survey research firm , said that last year the total purchase price will be state purchasing and storage of up to 60 billion yuan.

As profitable , some companies and investment companies will move from the " brains ."

The firm told reporters : "There is already done this enterprise , the most direct way is , A company is a state-owned purchasing and storage qualification , B plant is acquired businesses , you can buy some from outside the purchasing and storage products with low prices , as purchasing and storage enterprises sold to A , A company then sold to the state . "

"This is actually for those small businesses is very dangerous , over-reliance on purchasing and storage , and large enterprises , once the big companies do not charge your product , and small businesses will become impossible to separate the face of the market . " Another rare corporate executives said.

In addition, some investment companies holding the investors' funds to participate in purchasing and storage enterprises to participate in purchasing and storage enterprises took the money to the market to buy cheap products that can Shouchu as storage price higher than the market of rare earth Price , participating companies will make a small fortune purchasing and storage , and the investment company will also get a good income . It is understood that investment companies do this kind of business , investment return rate of 10 % or more.

Baotou a responsible person that compared with other countries , China 's rare earth Shouchu work has only just started, purchasing and storage mechanisms , price, type, quantity , and many other problems to be solved. Otherwise, purchasing and storage only become big business making money .
