Ngokuphathelene nesici sokuhlinzeka, i-calcium carbide, ngesonto eledlule, intengo yemakethe eyinhloko ye-calcium carbide yehliswe ngama-yuan angu-50-100 ngethani. Umthwalo wokusebenza ophelele wamabhizinisi e-calcium carbide wawuzinzile, futhi ukunikezwa kwezimpahla kwakwanele. Ngenxa yobhubhane, ukuthuthwa kwe-calcium carbide akuhambanga kahle, intengo yefektri yamabhizinisi yehlisiwe ukuze kuvunyelwe ukuthuthwa kwenzuzo, ingcindezi yezindleko ze-calcium carbide inkulu, futhi ukwehla kwesikhashana kulindeleke ukuthi kuncishiswe. Umthwalo wokuqala wamabhizinisi akhuphukayo e-PVC ukhuphukile. Ukugcinwa kwamabhizinisi amaningi kugxile maphakathi nasekupheleni kuka-Ephreli, futhi umthwalo wokuqala uzohlala uphakeme kakhulu esikhathini esifushane. Ngenxa yobhubhane, umthwalo wokusebenza wamabhizinisi angaphansi komhlaba uphansi, isidingo sibuthakathaka, futhi uhlu lwamabhizinisi athile okukhiqiza e-PVC endaweni yesitshalo lukhuphukile ngenxa yokuthuthwa okubi.
Kusukela ngo-Ephreli 6, intengo ye-PVC e-Asia ayishintshanga kakhulu kuleli sonto. I-CFR China isalokhu i-US $1390 / ithani, i-Southeast Asia isalokhu i-US $1470 / ithani, kanti i-CFR India yehla ngo-US $10 yaya ku-US $1630 / ithani. Intengo yemakethe yangaphandle yahlala izinzile, kodwa ukuthunyelwa kwamanye amazwe kwakubuthakathaka kunasekuqaleni ngenxa yobuthakathaka obuqhubekayo bukawoyela ongahluziwe wamazwe ngamazwe. Kusukela ngo-Ephreli 7, idatha yamasonto onke ibonise ukuthi umthwalo wokusebenza we-PVC wawungu-82.42%, kanye nokwenyuka kwenyanga ngamaphesenti angu-0.22; Phakathi kwazo, umthwalo wokusebenza we-calcium carbide PVC wawungu-83.66%, wehle ngamaphesenti angu-1.27 ngenyanga.
I-Chemdo ibilokhu ithola imibuzo evela eNingizimu-mpumalanga ye-Asia, eMpumalanga Ephakathi nase-Afrika muva nje, futhi ukuthunyelwa kwamanye amazwe kusazinzile.
