Adjacent benzene is general-purpose colophony 340, double-loop (DC) the hand papers colophony 250, man-made stone / stone stone colophony 320, pull crowded colophony 340, twine structural layer colophony 350, twine a benzene liner colophony 340, colophony of NPG mould pressing 300, colophony of DPG mould pressing 440. Epidemic situation and “ double accuse converging attack of ” two sides, raw material market rises in the round, colophony price go up considerably again tone 500- - 800 yuan. This week UPR market breaks out two big influencing factor, it is influence of Fujian epidemic situation firstly, cause stop production of factory of UPR of this area much home or reduction in production, at the same time content sheds suffocate suffocate; The “ of specific power consumption that is arise suddenly secondly double accuse ” thunderbolt to be restricted electric measure, force shop of UPR of much home of Jiangsu, Shandong and Guangdong considerably reduction of output, partial plant is forced stop production. As a result of Jiangsu, Fujian, Guangdong and Shandong 4 provinces are area of UPR crop earth, the 4 80% above that save aggregate UPR crop to hold total output, factory of UPR of these 4 areas at the same time reduction of output, will cause tremendous effect to UPR market. Accordingly, before beginning to go to work to National Day from this week, UPR supplies ability effectively to drop considerably likely. The occurrence of this kind of circumstance, since going 30 years, never had had, can says is unprecedented, and as it happens is driven mid-autumn to mix the stock up season before National Day, downstream to UPR industry will tell, it may be said is one disaster after another. Many downstream client was mirrorred to us recently, in a month in the past, they according to us below " experience introduction " in recommends method and UPR factory sign contract of supply and marketing, in the process that rises considerably in this round of price already benefit good people is much. " experience introduction " : The downstream client of UPR is more very with export or project kind the market is relevant, accordingly downstream user often hopes to be in accept the order when can will export order for goods or one-time all lock decides the UPR amount that project order place needs and value, but the force with upriver market because UPR industry is right enough lack and control force, the price of UPR factory can passive follow of price of upriver raw material change and undertake adjustment. Accordingly, every time UPR price appears relatively during changing substantially, create the contradiction between UPR factory and downstream user easily. Divide the experience of the enterprise according to eye forehead, good means of settlement is UPR produces factory and downstream client to undertake deepness bind, the interest shares everybody, the risk is carried together, who doesn't blame. Particular way is: In sign gross contract when, sign a price to change adjust methodological clause, namely basis " colophony price index " the price index that publishs is fluctuant extent, both sides assumes price index severally 50% of fluctuant part, calculate every week the price, implement the price actually as what delivering goods day is in a week. The practice of partial enterprise proves, this kind of method not only fairness is reasonable, and those who have the price but foresight, need not both sides delivers goods every time want bargain. This experience consults for everybody.
