Ngomhla ziyi-13 kuNovemba 2018, uMnyango Wezohwebo wase-US (i-DOC) wenze isinqumo sokuqala sokulwa nokulahlwa kuma-quartz countertops angeniswe evela e-China.

Isinqumo sokuqala:
Imajini yokulahla ye-Foshan Yixin Stone Co. Ltd. (Xinyixin Co. Ltd.) ingu-341.29%, futhi izinga lediphozithi yesikhashana yokulwa nokulahlwa ngemva kokuqeda inani lentela eliphikisayo lingu-314.10%.
Imajini yokulahla ye-CQ International Limited (Meiyang Stone) ingama-242.10%, futhi izinga lediphozithi yesikhashana yokulwa nokulahlwa ngu-242.10%.
Imajini yokulahla ye-Guangzhou Hercules Quartz Stone Co., Ltd. (Haiglis) ingu-289.62%, futhi izinga lediphozithi yesikhashana yokulwa nokulahlwa ngu-262.43% ngemva kokuqeda inani lentela eliphikisayo.
Imajini yokulahla yabanye abakhiqizi/abathekelisi baseShayina abanamazinga entela ahlukene ngu-290.86%, futhi izinga lediphozithi yesikhashana yokulwa nokulahlwa ngu-263.67% ngemva kokuqeda izinga lentela eliphikisayo.
Imajini yokulahlwa yabakhiqizi/abathekelisi baseShayina abangayitholi intela ehlukile ingu-341.29%, futhi izinga lediphozithi yesikhashana yokulwa nokulahlwa ngemva kokuqeda izinga lentela eliphikisayo lingu-314.10%.
Ngokokuhlaziywa kokuqala, isizathu esenza i-DOC inqume izinga eliphezulu lentela esinqumweni sokuqala saleli cala ukuthi i-Mexico yakhethwa njengelinye izwe.E-Mexico, ezinye izintengo njengesihlabathi se-quartz (izinto zokusetshenziswa ezibalulekile zemikhiqizo ehilelekile) ziphezulu kakhulu.Isibalo sokulahla esiqondile sidinga ukuhlaziywa okwengeziwe.
Esinqumweni sokuqala sokulahla, i-DOC yaqala yaqaphela ukuthi zonke izinkampani "zinesimo esiphuthumayo", ngakho-ke izobeka idiphozi ephikisana nokulahlwa emikhiqizweni engenisiwe ehilelekile ezinsukwini ezingu-90 ngaphambi kokumiswa kokuvunyelwa kwentela.UMnyango Wezohwebo wase-US kulindeleke ukuthi wenze isinqumo sokugcina sokulwa nokulahlwa kuleli cala ekuqaleni kuka-Ephreli 2019.
Mayelana nalokhu, i-China Min metals Chamber of Commerce, i-Ministry of Commerce kanye ne-China Stone Association zilungele ukwethula ngokushesha ukuvikela okungonakali kwe-quartz yokwenziwa e-United States.Kuyaqondakala ukuthi inqobo nje uma isicelo esingelona ingozi singafakazela elinye lamaphuzu amathathu, izinqumo zokuqala ezikhona zizoqedwa zonke: okokuqala, imikhiqizo yaseShayina ayinabungozi emabhizinisini aseMelika;okwesibili, amabhizinisi aseShayina awalahli;okwesithathu, akukho ukuxhumana okudingekayo phakathi kokulahla nokulimala.
Ngokusho kwabantu abajwayelene nalesi simo, nakuba isimo sinzima kodwa asekhona amathuba.Futhi abangenisi baseMelika basebenza kanzima nezinkampani zamatshe zaseShayina ukuze zibhekane nazo.
Ngokwemibiko, izindleko eziphelele zokuzivikela okungabhubhisi ngokumelene ne-quartz yokufakelwa e-United States cishe i-250,000 US dollars (RMB 1.8 million), okudingeka ukuthi kwabelwane ngayo ngamabhizinisi amatshe.I-Fujian ne-Guangzhou yizinhlangano eziyinhloko, ezamukela isimiso sokuzihlanganisa ngokuzithandela.Phakathi kwazo, uFujian unethemba lokuhlela cishe ama-yuan ayizigidi ezingu-1.Kwethenjwa ukuthi amabhizinisi aseSifundazweni saseFujian azobamba iqhaza ngokugcwele.
