I-United States ibeke imirhumo enzima kwi-MDI yaseTshayina, kunye namazinga omsebenzi wokuqala kwisikhululo seshishini laseTshayina esisetiwe phezulu njenge-376% -511%. Oku kulindeleke ukuba kube nefuthe ekufunyanweni kweemarike zangaphandle kwaye kunokonyusa ngokungangqalanga uxinzelelo kwiintengiso zangaphakathi.

I-US ibhengeze iziphumo zokuqala zophando lwayo oluchasene nokulahla i-MDI evela e-China, kunye namaxabiso aphezulu aphezulu kakhulu awothusayo kulo lonke ishishini lemichiza.

ISebe lezoRhwebo lase-US linqume ukuba abavelisi be-MDI baseTshayina kunye nabathengisi bathengisa iimveliso zabo e-US kwiindawo zokulahla i-376.12% ukuya kwi-511.75%. Inkampani yaseTshayina ephambili ifumene ireyithi yomsebenzi wokuqala oyi-376.12%, ngelixa abanye abavelisi abaninzi baseTshayina abangazange bathathe inxaxheba kuphando bejongene nenqanaba elifanayo lesizwe lama-511.75%.

Eli nyathelo lithetha ukuba, ngokulindela isigwebo sokugqibela, iinkampani zaseTshayina ezifanelekileyo kufuneka zihlawule iidiphozithi zemali kwi-US Customs-ixabiso eliphindwe kaninzi kwixabiso leemveliso zabo-xa zithumela i-MDI e-United States. Oku ngokufanelekileyo kudala umqobo worhwebo ophantse ubenakoyiswa kwixesha elifutshane, ukuphazamisa kakhulu ukuhamba korhwebo oluqhelekileyo lwe-MDI yaseTshayina ukuya e-US.

Uphando lwaqalwa okokuqala yi "Coalition for Fair MDI Trade," equlunqwe yiDow Chemical kunye ne-BASF e-US Ingqwalasela yayo ephambili kukukhuselwa kwezorhwebo kwiimveliso ze-MDI zaseTshayina ezithengiswa ngamaxabiso aphantsi kwimarike yaseMelika, ebonisa ukuthambekela okucacileyo kunye nokujoliswa. I-MDI yimveliso ebalulekileyo yokuthumela ngaphandle kweyona nkampani iphambili yaseTshayina, kunye nokuthunyelwa kwempahla kumazwe angaphandle e-US kubalelwa malunga ne-26% yokuthunyelwa kwayo kumazwe angaphandle kwe-MDI. Lo mlinganiselo wokhuseleko lorhwebo unefuthe elimandla kwinkampani kunye nabanye abavelisi be-MDI baseTshayina.

Njengondoqo wemathiriyeli ekrwada kumashishini afana neengubo kunye neekhemikhali, utshintsho kutshintsho kurhwebo lwe-MDI luchaphazela ngqo ikhonkco lemizi mveliso yasekhaya. Ukuthunyelwa ngaphandle kwe-MDI esulungekileyo yase-China ukuya e-US yehle kule minyaka mithathu idlulileyo, yehla ukusuka kwiitoni ezingama-4,700 (i-21 yezigidi zeedola) ngo-2022 ukuya kwi-1,700 yeetoni (i-5 yezigidi zeedola) ngo-2024, iphantse yaluphelisa ukhuphiswano lwemarike. Nangona ukuthunyelwa kwe-polymeric MDI kumazwe angaphandle kuye kwagcina umthamo othile (iitoni ezingama-225,600 ngo-2022, iitoni ezingama-230,200 ngo-2023, kunye neetoni ezingama-268,000 ngo-2024), ixabiso lentengiselwano liye laguquguquka kabukhali (i-473 yezigidi zeedola, i-319 yezigidi zeedola, kunye ne-392 yezigidi zeedola, kunye noxinzelelo lwe-392 yezigidi ngokuqhubekayo imida yamashishini.

Kwisiqingatha sokuqala se-2025, uxinzelelo oludibeneyo oluvela kuphando oluchasene nokulahla kunye nemigaqo-nkqubo yentlawulo sele ibonise iziphumo. Idatha yokuthumela ngaphandle kwiinyanga ezisixhenxe zokuqala ibonisa ukuba iRashiya iye yaba yindawo ephezulu yokuthunyelwa kwe-MDI ye-polymeric yaseChina kunye neetoni ezingama-50,300, ngelixa i-market ye-US yangaphambili iye yawela kwindawo yesihlanu. Isabelo semarike ye-MDI yaseTshayina e-US sichithwa ngokukhawuleza. Ukuba iSebe lezoRhwebo lase-US likhupha isigwebo sokugqibela, abavelisi abakhulu baseTshayina be-MDI baya kujongana noxinzelelo oluqatha lwemalike. Abakhuphisana nabo abafana ne-BASF Korea kunye ne-Kumho Mitsui sele becwangcise ukwandisa ukuthunyelwa kwempahla e-US, ejolise ekubambeni isabelo semarike esasibanjwe ngaphambili ziinkampani zaseTshayina. Kwangaxeshanye, unikezelo lwe-MDI ngaphakathi kwingingqi ye-Asia-Pacific kulindeleke ukuba luqiniswe ngenxa yokuthunyelwa kwamanye amazwe, okushiya iinkampani zasekhaya zaseTshayina zijongene nomceli mngeni ombini wokuphulukana neemarike zaphesheya kunye nokuhlangabezana nokuguquguquka kwikhonkco lonikezelo lwasekhaya.
