I te 7 o Tīhema, i roto i tētahi pūrongo, i kī te British Iron and Steel Association, ko te pikinga ake o ngā utu hiko i ērā atu whenua Pākehā ka pā kino ki te whakawhiti waro-iti o te umanga maitai o Peretānia. Nō reira, i karanga te rōpū ki te kāwanatanga o Peretānia kia tapahia āna ake utu hiko.
E ai ki te pūrongo, me utu e ngā kaihanga rino o Peretānia he 61% te nui ake o ngā pire hiko i ō rātou hoa mahi i Tiamana, me te 51% te nui ake o ngā pire hiko i ō rātou hoa mahi i Wīwī.
"I te tau kua hipa, kua tata rua te pikinga o te rerekētanga utu hiko i waenga i te UK me te toenga o Ūropi," te kī a Gareth Stace, te kaiwhakahaere matua o te British Iron and Steel Institute. Kāore e taea e te umanga maitai te haumi nui ki ngā taputapu hou matatau e kaha ana ki te whakamahi i te hiko, ā, ka uaua ki te whakatutuki i te whakawhiti iti-waro."
E ai ki ngā pūrongo, mēnā ka hurihia te oumu waro i te UK hei taputapu hanga maitai hauwai, ka piki ake te whakapaunga hiko mā te 250%; mēnā ka hurihia hei taputapu hanga maitai pewa hiko, ka piki ake te whakapaunga hiko mā te 150%. E ai ki ngā utu hiko o nāianei i te UK, ko te whakahaere i te umanga hanga maitai hauwai i te whenua ka tata ki te 300 miriona pauna/tau (tata ki te US$398 miriona/tau) te utu nui ake i te whakahaere i te umanga hanga maitai hauwai i Tiamana.
