Kua whakatakotohia e te Hononga o Amerika he taake taumaha ki runga i ngā MDI Hainamana, me ngā reiti taake tuatahi mō tētahi umanga nui o Haina kua whakaritea kia eke ki te 376%-511%. E matapaetia ana ka pā tēnei ki te whakaurunga o te mākete kaweake, ā, ka kaha ake pea te pēhanga ki ngā hoko ā-rohe.

I whakapuakina e te US ngā hua tuatahi o tana rangahau ārai-dumping ki te MDI i ahu mai i Haina, ā, i ohorere te umanga matū katoa i ngā reiti taripa tino teitei.

I whakatauhia e te Tari Tauhokohoko o Amerika i hokona e ngā kaihanga me ngā kaweake MDI Hainamana ā rātou hua ki te US i roto i ngā tawhē tāpaetanga mai i te 376.12% ki te 511.75%. I whiwhi te kamupene Hainamana matua i te reiti takoha tuatahi motuhake o te 376.12%, i te mea he maha atu ngā kaihanga Hainamana kāore i uru ki te rangahau e pāngia ana e te reiti takoha ōrite puta noa i te motu o te 511.75%.

Ko te tikanga o tēnei nekehanga, i te mea kei te tatari kia puta he whakataunga whakamutunga, me utu e ngā kamupene Hainamana e tika ana ngā moni tāpui ki te Tari Taake o Amerika—he maha ngā wā e nui ake ai te uara o ā rātou hua—ina kaweake ana i te MDI ki te Hononga o Amerika. Nā tēnei ka hangaia he arai hokohoko tata kore e taea te wikitoria i roto i te wā poto, ka tino whakararuraru i ngā rere hokohoko noa o te MDI Hainamana ki te US.

I tīmatahia te rangahau e te "Coalition for Fair MDI Trade," i titoa mai i a Dow Chemical me BASF i te US. Ko tana arotahi matua ko te tiaki hokohoko mai i ngā hua MDI Hainamana e hokona ana i ngā utu iti i te mākete o Amerika, e whakaatu ana i te whakaaro pōhēhē me te arotahi. He hua kaweake nui te MDI mō te kamupene Hainamana matua, me ngā kaweake ki te US e tata ana ki te 26% o ana kaweake MDI katoa. He nui te pānga o tēnei tikanga tiaki hokohoko ki te kamupene me ētahi atu kaihanga MDI Hainamana.

Hei rauemi mata matua mō ngā ahumahi pēnei i ngā paninga me ngā matū, ka pā tika ngā huringa o ngā mahi hokohoko MDI ki te mekameka ahumahi ā-rohe katoa. Kua tino heke te kaweake a Haina i te MDI parakore ki te US i ngā tau e toru kua pahure ake nei, mai i te 4,700 tāne ($21 miriona) i te tau 2022 ki te 1,700 tāne ($5 miriona) i te tau 2024, tata tonu te whakakore i tōna whakataetae mākete. Ahakoa i mau tonu te nui o ngā kaweake MDI polymeric (225,600 tāne i te tau 2022, 230,200 tāne i te tau 2023, me te 268,000 tāne i te tau 2024), kua tino piki haere ngā uara tauwhitinga ($473 miriona, $319 miriona, me te $392 miriona), e tohu ana i te pēhanga utu mārama me te heke tonu o ngā tawhē hua mō ngā umanga.

I te haurua tuatahi o te tau 2025, kua kitea kētia ngā pānga o te pēhanga whakakotahi mai i te rangahau ārai-tuku me ngā kaupapa here taripa. E whakaatu ana ngā raraunga kaweake mai i ngā marama tuatahi e whitu kua riro a Rūhia hei wāhi matua mō ngā kaweake MDI polymeric a Haina me te 50,300 tana, i te mea kua heke te mākete matua o Amerika ki te tuarima o ngā tūranga. Kei te tere te memeha o te wāhi mākete MDI a Haina i te US. Mena ka tukuna e te Tari Tauhokohoko o Amerika he whakataunga whakamutunga, ka nui ake te pēhanga mākete mō ngā kaihanga MDI nui o Haina. Kua whakamahere kē ngā kaiwhakataetae pēnei i a BASF Korea me Kumho Mitsui ki te whakanui ake i ngā kaweake ki te US, me te whai kia hopukina te wāhi mākete i puritia e ngā kamupene Haina i mua. I te wā kotahi, e matapaetia ana ka whakawhāitihia te tuku MDI i roto i te rohe o Āhia-Moana-nui-a-Kiwa nā te mea kua hurihia ngā kaweake, ka waiho ngā kamupene Haina o roto e anga atu ana ki te wero rua o te ngaronga o ngā mākete o tāwāhi me te tūtaki ki te huringa o te mekameka tuku ā-rohe.
