Raw material market is overall hasten is weak, UPR market keeps stable. Market of this week raw material is overall present weak potential, it is downstream demand lasts on one hand fatigued and weak, it is upriver new increase production on one hand additionally can put into production anticipates increase. New the official PMI index that publish falls the low since Feburary 2020, explain pressure of economic be issued to lower levels is increased unexpectedly; The new coronal epidemic situation that causes by airport of Nanjing salary mouth presents spreading position, prevent as each district accuse measure to raise the price of the commodities ceaselessly, the negative effect that manages to production begins to be shown stage by stage. Will anticipate order case will look what feedback from each UPR factory August, on the whole very not hopeful, each company desired value under July, now year first half of the year, while whole UPR industry grows considerably compared to the same period with price in sales volume, unit profit drops considerably however more than 60% above, the market situation that place of industry of this shows UPR faces is very grim. What this kind of circumstance needs to cause trade of UPR upper reaches is enough take seriously, if insist to seek short-term increase and ignore the healthy and orderly development of whole industry catenary again, so before long in the future, of market of partial raw material breaking down also can be imagined. In recent years since, especially since this year, the blame reason of price of partial raw material goes up madly, had brought to UPR factory colliding tremendously is to detest psychology even, they are opposite generally from the back new increase production can express great expectations, most UPR works shows, below coequal condition, they aux would rather the product that selects new supplier, in order to convey them the accumulated rancor of manufacturer of production of raw material of original to the part advanced position and dissatisfaction, accordingly, the new increase production of follow-up put into production can be welcomed generally by UPR factory, these new increase production can enter the pace of the market to meet those who break a rule accelerate. Suffer epidemic situation effect, the forum of development of not saturated colophony that holds in Jiangsu Changzhou on August 12 formerly is forced to adjourn hold, specific time informs separately. " 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.
