ʻO MIT-IVY INDUSTRY CO., LTD kahi mea hana a me ka mea hoʻokuʻu aku i nā mea hoʻonaninani kemika maikaʻi a me nā mea hana lāʻau lapaʻau ma Kina.
ʻOi aku ka hana ʻana i nā huahana moʻo aniline a me nā huahana moʻo chlorine.
ʻO MIT –IVY Chemicals Industry Co., Ltd. kahi mea hana kemika alakaʻi no 21 mau makahiki me nā lako hana piha a me ka hoʻokele pono a me ka mālama ʻana i nā mīkini.
Hoʻohana mākou i ka ʻenehana hana holomua a me nā ʻano hoʻāʻo e hoʻokō i ka hana ʻana, ka kaohi maikaʻi e hoʻokō i ke kūlana. Ua ʻae ʻia mākou e SGS, ISO9001, ISO140 01, GB/HS16949 a me T28001.
ʻO nā huahana nui a Mit-Ivy e like me kēia:
API, nā mea lapaʻau lāʻau lapaʻau, nā mea hoʻoheheʻe kala, nā kemika maikaʻi, nā kemika kūikawā, ka pena ʻoihana wai a me nā mea ikehu hou.
ʻO kā mākou mau mākeke nui e pili ana iā ʻAmelika, India, ʻApelika, Indonesia, Turkey, Asia Hema-Hikina, Asia Komohana a pēlā aku. Loaʻa i nā huahana MIT-IVY Industry Main nā 97% o ka mākeke kūloko e loea ana i ka hana ʻana a me ka hoʻokele, hiki iā mākou ke hoʻolako i nā huahana me ke kumukūʻai hoʻokūkū. me ke kūlana kiʻekiʻe a me ke kumukūʻai a hoʻokipa ʻia e kūkākūkā. Loaʻa i kā mākou hui nā poʻe loea e koʻikoʻi ana i ka R&D kemika a me ka hoʻokele sicentific, hoʻolako i nā huahana kemika maikaʻi me ke kūlana kiʻekiʻe a me ka lawelawe kokoke, hoʻolako pū i nā huahana i hana ʻia e like me nā koi o kā mākou mea kūʻai aku. Loaʻa iā mākou kahi hui hana hoʻokele maikaʻi a hoʻoikaika ponoʻī me kahi ʻano maʻamau, mālama a me ka hoʻokō ma o ka hana hui, hoʻoikaika kā mākou hui e hoʻokō i ka holomua i ka hauʻoli ʻana i kā mākou mea kūʻai aku a me mākou iho. hoʻomau mākou i ka hana hou ʻana i kā mākou huahana a hoʻomaikaʻi i kā mākou lawelawe, pūnaewele kūʻai aku. No laila, hoʻomaka mākou i ke ʻano kūʻai mua ma ka pūnaewele ma Kina, ʻo ia ke kālepa kūʻai liʻiliʻi o nā ʻano hoʻokele like ʻole. Hoʻokuʻu nui ʻia kā mākou huahana i Korea Hema, Vietnam, Australia, ʻEulopa a me ʻAmelika Hema, i ʻōlelo nui ʻia e kā mākou mea kūʻai aku. Ke koi nei mākou i ka manaʻo hoʻokele "ʻO ka mākeke kā mākou panana, ʻO ka maikaʻi ko mākou ola, ʻO ka hōʻaiʻē ko mākou ʻuhane". ʻO ka hilinaʻi o nā mea kūʻai aku kā mākou pauka mua, ʻo ko lākou ʻoluʻolu kā mākou pahuhopu hakakā.
Hana lawelawe mea kūʻai aku:
Hoʻomohala a hoʻokō kā mākou pūnaewele hui lawelawe mea kūʻai aku JIT ma Kina i nā manaʻo i hana kūikawā ʻia no ka hoʻolako kūpono ʻana i kā mākou mea kūʻai aku me nā kemika ʻoihana a me nā kemika kūikawā.
ʻO kāu mau pono:
● Kākoʻo ka lawelawe mea kūʻai aku kikowaena i ka maʻalahi o nā kaʻina hana hoʻomalu, e hopena ana i ka mālama manawa a me ke kālā.
● Hōʻoia kā mākou pūnaewele Kina a me nā hoʻonā logistics akamai e hoʻolako ʻia nā kemika o ke ʻano like i nā mea kūʻai aku me kekahi mau wahi hana a kōkua i ka palekana i ka hoʻolālā a me ka hilinaʻi o nā kaʻina hana.
● Hoʻomaikaʻi mau ʻia kā mākou mau kaʻina hana a hoʻololi ʻia i nā ʻano a me nā koi e loli nei o kā mākou mea kūʻai aku.
ʻOi aku ka maikaʻi o ka lawelawe Chemistry Logistics:
He ʻoihana loa ka lawelawe logistic kemika a pono e ʻoi aku ka maikaʻi ma lalo o ke kānāwai UN, ʻoi aku hoʻi no ka moʻo DGR Class. Hāʻawi mākou i kahi hopena kūikawā e hoʻomaikaʻi i ka logistic a me ka lawelawe hui hoʻopili kūpono a me ka lepili no kā mākou mau luna. ʻO kā mākou mau awa Kina nui me nā hale kūʻai kemika DGR e hana i nā kemika kūikawā a hoʻopili i nā palapala pili āpau e pili ana.
ʻO kā mākou mau hiki ke hoʻolaha:
● Nā hoʻouna maʻalahi, nā hoʻonā akamai
● Mai nā hoʻouna nui ʻana he mau tausani tone a hiki i ka hoʻouna liʻiliʻi loa o nā waiwai i hoʻopaʻa ʻia a me nā laʻana.
● Nui - ka mālama ʻana a me ka lawe ʻana i nā pauka a me nā wai - ka neʻe ʻana o nā waiwai ma nā moku - nā pauka a me nā wai nui
● Ka mālama ʻana i nā meaʻai lāʻau lapaʻau, nā meaʻai hānai a me nā meaʻai i nā kūlana i hōʻoia ʻia
● Nā mea i hoʻokaʻawale ʻia e ka ʻāpana ʻoihana a me ka hoʻokaʻawale ʻana i nā pōpilikia
● Ka mālama ʻana a me ka lawe ʻana i ka mahana i kāohi ʻia
● Ka hoʻokele waiwai kūpono
● Hoʻopili hou ʻana, hoʻopiha pahu, ʻeke ʻana, haehae ʻana a me ka hoʻohuli ʻana
