I-United States ibeke irhafu enzima kwi-MDI yaseTshayina, kunye namaxabiso okuqala erhafu kwinkampani enkulu ekhokelayo kushishino lwaseTshayina abekwe phezulu ukuya kwi-376%-511%. Oku kulindeleke ukuba kube nefuthe ekutsalweni kwemarike yokuthumela ngaphandle kwaye kunokunyusa uxinzelelo ngokungathanga ngqo kwintengiso yasekhaya.

I-US ibhengeze iziphumo zokuqala zophando lwayo oluchasene nokulahlwa kwenkunkuma kwi-MDI evela eTshayina, kunye namaxabiso aphezulu kakhulu amangalisa lonke ishishini leekhemikhali.

ISebe lezoRhwebo lase-US lifumanise ukuba abavelisi kunye nabathumeli bemveliso baseTshayina abathengisa iimveliso zabo e-US ngexabiso eliphantsi ukusuka kwi-376.12% ukuya kwi-511.75%. Le nkampani iphambili yaseTshayina ifumene irhafu yokuqala ye-376.12%, ngelixa abanye abavelisi baseTshayina abangazange bathathe inxaxheba kuphando bejongene nerhafu efanayo ye-511.75% kuzwelonke.

Eli nyathelo lithetha ukuba, ngelixa kusalindwe isigqibo sokugqibela, iinkampani zaseTshayina ezifanelekileyo kufuneka zihlawule imali ediphozithiweyo kwi-US Customs—ixabiso eliphindwe kaninzi kunexabiso leemveliso zazo—xa zithumela i-MDI eMelika. Oku kudala umqobo worhwebo ongenakunqotshwa kwixesha elifutshane, okuphazamisa kakhulu ukuhamba kwezorhwebo okuqhelekileyo kwe-MDI yaseTshayina eMelika.

Olu phando lwaqalwa yi-“Coalition for Fair MDI Trade,” eyakhiwa yiDow Chemical kunye neBASF e-US. Ingqwalasela yayo ephambili kukukhusela urhwebo kwiimveliso ze-MDI zaseTshayina ezithengiswa ngamaxabiso aphantsi kwimarike yaseMelika, nto leyo ebonisa ukuthambekela okucacileyo kunye nokujolisa. I-MDI yimveliso ebalulekileyo yokuthumela ngaphandle kwenkampani ephambili yaseTshayina, apho ukuthunyelwa kwamanye amazwe e-US kuthwala malunga ne-26% yeempahla zayo ezithunyelwa ngaphandle ze-MDI. Le ndlela yokukhusela urhwebo ichaphazela kakhulu inkampani kunye nabanye abavelisi be-MDI baseTshayina.

Njengezinto eziphambili zokwenza imveliso kumashishini afana neengubo kunye neekhemikhali, utshintsho kwi-MDI dynamics yorhwebo luchaphazela ngokuthe ngqo lonke uthotho lwemizi-mveliso yasekhaya. Ukuthunyelwa kwe-MDI ecocekileyo e-China e-US kuye kwehla kwiminyaka emithathu edlulileyo, kwehla ukusuka kwiitoni ezingama-4,700 ($21 yezigidi) ngo-2022 ukuya kwiitoni ezili-1,700 ($5 yezigidi) ngo-2024, phantse kutshabalalisa ukukhuphisana kwayo kwimarike. Nangona ukuthunyelwa kwe-MDI nge-polymeric kuye kwagcina umthamo othile (iitoni ezingama-225,600 ngo-2022, iitoni ezingama-230,200 ngo-2023, kunye neetoni ezingama-268,000 ngo-2024), amaxabiso entengiselwano atshintshile kakhulu ($473 yezigidi, i-$319 yezigidi, kunye ne-$392 yezigidi ngokulandelelana), nto leyo ebonisa uxinzelelo lwamaxabiso olucacileyo kunye nokuncipha rhoqo kwemida yenzuzo kumashishini.

Kwisiqingatha sokuqala sowama-2025, uxinzelelo oludibeneyo oluvela kuphando lokulwa nokulahla inkunkuma kunye nemigaqo-nkqubo yerhafu sele ibonakalise iziphumo. Idatha yokuthumela ngaphandle evela kwiinyanga ezisixhenxe zokuqala ityhila ukuba iRashiya ibe yindawo ephambili yokuthumela ngaphandle kwe-MDI ye-polymeric yaseTshayina ngeetoni ezingama-50,300, ngelixa imarike eyayisakuba yeyona iphambili e-US iye yehla yaya kwindawo yesihlanu. Isabelo semarike ye-MDI yaseTshayina e-US siyawohloka ngokukhawuleza. Ukuba iSebe lezoRhwebo lase-US likhupha isigqibo sokugqibela esivumayo, abavelisi abakhulu be-MDI baseTshayina baya kujongana noxinzelelo olunzima ngakumbi lwemarike. Abakhuphisanayo abanjengoBASF Korea kunye noKumho Mitsui sele becebe ukwandisa ukuthunyelwa kwamanye amazwe e-US, bejolise ekubambeni isabelo semarike esasibanjwe ziinkampani zaseTshayina ngaphambili. Kwangaxeshanye, ukunikezelwa kwe-MDI kummandla we-Asia-Pacific kulindeleke ukuba kuqine ngenxa yokuthunyelwa kwamanye amazwe okuqondiswe kwenye indawo, okushiya iinkampani zaseTshayina zasekhaya zijongene nomngeni ophindwe kabini wokulahlekelwa ziimarike zaphesheya kwaye zijongane nokuguquguquka kwikhonkco lokubonelela lendawo.
