Kubelesya kwa sodium sulfide mumakkampani kulabikkilizya azintu zikatazya kumvwisisisya. Mumasena aakuyiisya idayi, babelesi babeleka kabasamide zisani zitakonzyi kunjililwa misamu nkaambo sodium sulfide ilagwisya muya uutali kabotu aawo nokwapya kapati. Maanda aakusanzya maanzi aasofweede kanjikanji alabelesya kuyobola zintu zilemu, eezi ziyandika kweendelezya loko mweelwe wakusanzya akubikka mumapaipi aakusanzya azibelesyo zikwabilila kuti kutabi mabwe. Muzigayo zyamapepa, ooko nkozibelesyegwa kuteteeta nkuni, busena bwakubelekela bweelede kuzumanana kuyuma, amatepu aatakwe kutezemuka ansi antoomwe azitondezyo zyakuchenjezya zilimbuli kuti "Kunyina nkomeki zyamaanzi zizumizigwa" zibikkidwe abwaanda.

Kutumizya zintu kuzwa ku Qingdao Port, Tianjin Port, antoomwe a Shanghai Port, anzila zibeleka kabotu zya sodium sulfide zivwumbilide mato mapati munyika yoonse. Dina aawa kuti ujane milimu iili kabotu.
