Nk'uko ibitangazamakuru byo mu mahanga byatanga raporo ku ya 29 Gicurasi, ku isi hosealuminiumProducer yasubiyemo amadorari 175 kuri toni ya aluminiUm koherezwa mu Buyapani mu gihembwe cya gatatu cyuyu mwaka, kiba gifite imyaka 18-21% kurenza igiciro mugihembwe cya kabiri. Nta gushidikanya ko aya magambo ya Scain yerekanye nta gushidikanya ko asaba amatero yo gutanga amaso asabwa ku isoko rya aluminium ku isi.

 
Aluminum premium, nkitandukaniro riri hagati yigiciro cya aluminium nigiciro cyibipimo, mubisanzwe bifatwa nkimyambaro yo gutanga isoko nibisabwa. Mu gihembwe cya kabiri cy'uyu mwaka, abaguzi b'Abayapani bemeye kwishyura mbere y'amadorari 145 kugeza $ 148 kuri toni ya alumini, yiyongereye ugereranije n'igihembwe gishize. Ariko mugihe twinjiye mugihembwe cya gatatu, kwiyongera mubiciro bya aluminium biratangaje, byerekana ko amakimbirane yo gutanga mu isoko rya aluminium ahora akomera.
Intandaro yiki gihe kigizwe no gutanga isoko kumuryango wa aluminium yisi yose. Ku ruhande rumwe, kwiyongera guhoraho mu rwego rwo kunywa ku buhunzi mu karere ka Aluminium byatumye abahinzi ba aluminiyumu bahindukirira isoko ry'ibihugu by'Uburayi, bityo bikagabanya amasoko y'Abanyaburayi mu karere ka Aziya. Iri sembano yo kurengera mu karere yarushijeho kubura ikibazo cyo gutanga amakuru ya Aluminum mu karere ka Aziya, cyane cyane ku isoko ry'Ubuyapani.

 
Ku rundi ruhande, amafaranga menshi ya alumunum muri Amerika ya ruguru ni hejuru cyane kuruta uko muri Aziya, arushaho kwerekana ubusumbane mu isoko rya jo ku isi. Uku kubumba ntabwo bigaragarira gusa muri kariya karere gusa, ahubwo bigaragarira no ku isi yose. Hamwe no gukiza ubukungu bwisi yose, icyifuzo cya aluminium buhoro buhoro, ariko itangwa ntirikomeza mugihe gikwiye, kiganisha ku kwiyongera gumbye mubiciro bya alumini.

 
Nubwo abaguzi ba ku isi yose, abaguzi b'Abayapani ba aluminiyu bemeza ko amagambo avuye mu gutanga abatanga amakuru yo mu mahanga ari hejuru cyane. Ibi biterwa ahanini no gukenera uburwayi mu nganda zo mu Buyapani no kubaka inganda zo mu Buyapani, hamwe n'ibarura ry'imbere mu gihugu mu Buyapani. Kubwibyo, abaguzi b'Abayapani ba aluminiyumu bitondera amagambo avuye mu gutanga abatanga amakuru ahishwa.
