Adjacent benzene is general-purpose colophony 230, double-loop (DC) the hand papers colophony 300, man-made stone / stone stone colophony 290, pull crowded colophony 300, twine structural layer colophony 290, twine a benzene liner colophony 220, colophony of NPG mould pressing 120, colophony of DPG mould pressing 610. Concussion of perch of raw material market, colophony price lasts on tone 300-500 yuan. Perch of this market of week raw material is strong concussion, go up drop each other shows, UPR cost rises continuously, be forced to follow on tone price, so far, 9, the amplitude modulation on accumulative total of price of UPR of two 10 months has exceeded every tons 2000 yuan. The international oil price that helps the ingredient that uses UPR price to rise continuously remain place of our early days to narrate at present rises continuously, be restricted conductance sends supply of partial raw material to decrease and export price goes high to pull continuously move home market to rise in price these 3 respects. But, meanwhile, we remind the enterprise inside course of study to notice here, UPR price rises at present such degree, form the situation of refuse to budge that swims up and down very likely. Will tell to downstream enterprise, UPR price rises continuously the gain level that already great rate reduced downstream enterprise, and as UPR price rise increasingly, to the circulating fund of downstream enterprise the quantity also creates greater and greater pressure, at the same time weather situation also meets those who bring about downstream enterprise to produce rhythm to put delay. Meanwhile, new of epidemic situation of round of new coronal diffuse quickly, be opposite 2 weeks later in future likely the market brings negative effect. Accordingly, we suggest all enterprises on UPR industry catenary want to handle the situation that rises in price nowadays carefully, pay close attention to the change of the market closely, notice avoid market goes the risk of the bureau. 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.
