8-dii bishii May ee waqtiga maxalliga ah, Boqortooyada Ingiriiska iyo Maraykanku waxay gaadheen heshiis ku saabsan qodobbada heshiiska ganacsiga tariifada, iyadoo diiradda lagu saarayo hagaajinta tacriifadaha wax soo saarka iyo alaabta ceeriin, iyadooqiimaha alaabta aluminiumqabanqaabada oo noqonaysa mid ka mid ah arrimaha ugu muhiimsan ee wada xaajoodka laba geesoodka ah. Sida ku cad qaab-dhismeedka heshiiska, dawladda Ingriisku waxay ku beddeshay dhimista tacriifta warshadaha mudnaanta leh ee UK iyadoo hagaajinaysa caqabadaha qaybo gaar ah, halka Maraykanku uu sii haysto 10% tariif aasaasiga ah ee aagagga asaasiga ah sida "xadka dhismaha."

Bayaan rasmi ah oo ay soo saartay dawladda Ingiriiska isla maalintaas ayaa muujisay in isbeddelka tacriifadda ay si weyn u saamaysay warshadaha wax soo saarka biraha: canshuuraha UK u dhoofinta birta iyo aluminiumka ee Maraykanka ayaa laga dhimi doonaa 25% eber. Siyaasaddani waxay si toos ah u dabooshaa qaybaha ugu muhiimsan ee alaabta aluminiumka ah ee ay UK u dhoofiso Maraykanka, oo ay ku jiraan aluminiumka aan shaqayn, profile-yada aluminiumka, iyo qaybo aluminium ah oo la farsameeyey. Xogtu waxay muujineysaa in UK ay u dhoofisay ku dhawaad ​​180,000 oo tan oo aluminium ah Mareykanka sanadka 2024, siyaasada eber-tarifka ayaa la filayaa inay badbaadiso shirkadaha wax soo saarka aluminium ee UK qiyaastii £80 milyan oo qarashka canshuuraha ah sanadkii, taasoo si weyn kor ugu qaadaysa tartankooda qiimaha suuqa Waqooyiga Ameerika. Waxaa xusid mudan, halka Mareykanku uu meesha ka saaray canshuuraha alaabada aluminiumka, waxay u baahneyd in UK la dhoofiyoalaabta aluminium si ay ula kulmaanHeerarka raadraaca "soosaarka kaarboon-yar", kuwaas oo ah in ugu yaraan 75% tamarta wax-soo-saarka ay tahay inay ka yimaadaan ilo dib loo cusboonaysiin karo. Xaaladdan dheeriga ah waxay rabta in ay la jaanqaado istiraatijiyadda "wax-soo-saarka cagaarka" gudaha Mareykanka.

Qaybta baabuurta, tacriifadda baabuurta UK ee loo dhoofiyo Maraykanka ayaa laga dhimi doonaa 27.5% ilaa 10%, laakiin baaxaddu waxay ku kooban tahay 100,000 baabuur sannadkii (oo daboolaya 98% wadarta guud ee baabuurta UK u dhoofiso Maraykanka 2024). Labada dhinacba waxay si gaar ah u caddeeyeen in qaybaha chassis-ka aluminiumka, qaybaha dhismaha jirka, iyo qaybaha kale ee aluminium-ku-saleysan ee baabuurta la dhimay ay tahay in ay ku xisaabtamaan wax aan ka yarayn 15%, taas oo si aan toos ahayn u kicinaysa warshadaha baabuurta UK si ay u kordhiyaan saamiga isticmaalka aluminium gudaha iyo xoojinta iskaashiga UK-US ee silsiladda warshadaha baabuurta tamarta cusub.

Falanqeeyayaasha ayaa tilmaamaya in "tarifka eber" ee aluminiumka iyo shuruudaha raadraaca-kaarboon-yar aysan ka tarjumaynin aqoonsiga Maraykanka ee tignoolajiyada warshadaynta aluminium ee UK laakiin sidoo kale waxay tusinaysaa qaabkeeda istaraatiijiyadeed ee cagaarinta silsiladda sahayda aluminiumka caalamiga ah. Boqortooyada Midowday (UK), siyaasadda eber-tarifku waxay u furaysaa gelitaanka suuqa Maraykanka ee alaabteeda aluminium, laakiin waa inay dardargelisaa beddelka kaarboonkawax soo saarka aluminium electrolyticawoodda-hadda, qiyaastii 60% wax soo saarka aluminium ee UK ayaa wali ku tiirsan gaaska dabiiciga ah. Mustaqbalka, waxa ay u baahan doontaa in ay la kulanto heerarka Maraykanka iyada oo soo bandhigaysa tamarta la cusboonaysiin karo ama farsamada qabashada kaarboonka. Dadka u dhuun daloola warshaduhu waxay aaminsan yihiin in tani ay ku qasbi karto warshadaha aluminium ee UK inay dardargeliyaan isbeddelkooda iyo cusboonaysiinta si ay u gaadhaan silsilad-warshadeed buuxa oo-carbonization-yar marka la gaadho 2030.
