Adjacent benzene is general-purpose colophony 290, double-loop (DC) the hand papers colophony 370, man-made stone / stone stone colophony 210, pull crowded colophony 260, twine structural layer colophony 290, twine a benzene liner colophony 260, colophony of NPG mould pressing 360, colophony of DPG mould pressing 450. Raw material market rises in the round, colophony price continues to move 300- - 600 yuan. Price of this week raw material is common go up considerably raise, arranging anhydride among them is the record of the 2nd high price that achieves throughout history again more, the high point since achieving 4 years, UPR is forced to go up tone price. At present UPR follows the independent prices that raw material market has walked out of upper reaches one round to ignore next processional trade demand completely, below the circumstance that bilges in such sluggish, the progressively and atrophic unavoidable of total output. The central issue that this week needs to pay close attention to particularly is the progress of Fujian epidemic situation. The new coronal epidemic situation of an arise suddenly arises in Fujian Pu cropland, from mere nucleic acid of 2 days detects in light of the result, this epidemic situation is likely scale is larger, and had spread to circumjacent area likely. Fontal city and area of border district of Pu Tian and week are town of military importance of production of Fujian Province UPR, collected the UPR productivity of major Fujian Province, if production of UPR of this one area and operation are affected by epidemic situation, so the UPR market that certainly will should give Guangdong, Fujian and Guangxi area supplies ability to bring severe impact, do not eliminate this week later period to reach values of afore-mentioned market of 3 ground UPR next week to appear to jump considerably continuously the possibility that go up. 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.
