N'ime yinye ụlọ ọrụ hydrocarbon aromatic, ọ fọrọ nke nta ka ọ bụrụ azụmaahịa ngwaahịa na-esi ísì ụtọ n'etiti ala China na United States. Agbanyeghị, US na-ebubata akụkụ dị ukwuu nke ngwaahịa na-esi ísì ụtọ sitere na Eshia, yana ndị na-ebubata Asia na-aza 40-55% nke US mbubata benzene, paraxylene (PX), toluene, na ngwakọta xylenes. A na-enyocha mmetụta ndị bụ isi n'okpuru:
Benzene
China na-ebubata nke ukwuu maka benzene, yana South Korea dị ka onye na-ebubata ya. Ma China na US bụ ndị na-eri benzene net, na-enweghị azụmaahịa ọ bụla n'etiti ha, na-ebelata mmetụta tarifu kpọmkwem na ahịa benzene nke China. Na 2024, ihe ndị South Korea ruru 46% nke mbubata benzene US. Dabere na data kọstọm South Korea, South Korea ebupụrụ ihe karịrị 600,000 metric ton nke benzene na US na 2024. Otú ọ dị, kemgbe Q4 2023, windo mkpebi dị n'etiti South Korea na US mechiri, na-emegharị South Korea benzene na-asọba na China-onye ahịa benzene kasị ukwuu nke Asia na ahịa China na-ebubata ọnụ ahịa dị elu. Ọ bụrụ na amanye tarifu US na-enweghị ewepu maka benzene dabere na mmanụ ala, ihe enyemaka zuru ụwa ọnụ nke ebuburu US nwere ike ibuga China, na-akwado oke mbubata. N'okpuru ala, mbupụ nke ngwaahịa benzene ewepụtara (dịka ọmụmaatụ, ngwa ụlọ, akwa) nwere ike chere nzaghachi na-adịghị mma n'ihi ịrị elu tarifu.
Toluene
Mbupụ toluene nke China etoola nke ọma n'afọ ndị na-adịbeghị anya, nke na-elekwasị anya na Ndịda Ebe Ọwụwa Anyanwụ Eshia na India, na azụmaahịa na-enweghị isi na US Agbanyeghị, US na-ebubata oke toluene sitere na Eshia, gụnyere 230,000 metric ton si South Korea na 2024 (57% nke mkpokọta US toluene mbubata). Tarifụ US nwere ike ịkpaghasị mbupụ toluene South Korea na US, na-eme ka oke ibu na Eshia na-abawanye asọmpi n'ahịa dị ka Ndịda Ebe Ọwụwa Anyanwụ Eshia na India, nwere ike imebi oke mbupụ China.
Xylene
China ka bụ onye na-ebubata ụgbụ nke xylenes agwakọta, na-enweghị azụmaahịa ya na US US na-ebubata nnukwu xylenes, ọkachasị na South Korea (57% nke mbubata US n'okpuru koodu HS 27073000). Agbanyeghị, ngwaahịa a gụnyere na ndepụta mwepu tarifu US, na-ebelata mmetụta na mmemme mkpezi Eshia-US.
Styrene
US bụ onye na-ebupụ styrene zuru ụwa ọnụ, na-ebunye Mexico, South America, na Europe, yana mbubata pere mpe (ton 210,000 na 2024, ihe fọrọ nke nta ka ọ bụrụ na Canada niile). A na-ebubata ahịa styrene nke China, na amụma mgbochi mkpofu egbochila azụmaahịa US-China ogologo oge. Agbanyeghị, US na-ezube itinye tarifu 25% na benzene South Korea, nke nwere ike ịbawanye ọkọnọ styrene Asia. Ka ọ dị ugbu a, mbupụ ngwa ụlọ sitere na styrene nke China (dịka ọmụmaatụ, ikuku oyi, friji) na-eche tarifụ US na-arị elu (ihe ruru ~ 80%), na-emetụta ngalaba a nke ukwuu. Ya mere, tarifụ US ga-emetụta ụlọ ọrụ styrene nke China site na ọnụ ahịa na-arị elu yana ebelata ọchịchọ ala.
Paraxylene (PX)
China na-ebupụ ihe fọrọ nke nta ka ọ bụrụ enweghị PX ma dabere na mbubata sitere na South Korea, Japan na Ndịda Ebe Ọwụwa Anyanwụ Eshia, na-enweghị azụmaahịa US. Na 2024, South Korea wetara 22.5% nke US PX mbubata (300,000 metric ton, 6% nke mkpokọta mbupụ South Korea). Tarifụ US nwere ike ibelata mgbaba South Korea PX na US, mana ọbụlagodi na ebuga ya na China, olu ahụ ga-enwe oke mmetụta. N'ozuzu, tarifụ US-China ga-emetụta ntakịrị PX mana ọ nwere ike na-amanye akwa akwa na mbupụ uwe na-apụtaghị ìhè.
Tarifụ US "ntụgharị uche" ga-emezigharị usoro ahia ahia zuru ụwa ọnụ nke hydrocarbons aromatic kama ịkpaghasị azụmahịa China na US ozugbo. Ihe egwu ndị dị mkpa gụnyere oke ibu n'ahịa Eshia, asọmpi siri ike maka ebe mbupụ, na nrụgide mgbada sitere na tarifụ dị elu na ngwa ahịa emechara (dịka ọmụmaatụ, ngwa, akwa akwa). Ụlọ ọrụ na-esi ísì ụtọ nke China aghaghị ịnyagharịa n'agbụ ọkọnọ atụgharịgharị wee mee mgbanwe n'usoro ihe achọrọ zuru ụwa ọnụ.
