Pehea e kūʻai mai ai iā mākou

Hiki iā Chemwin ke hāʻawi i ka nui o nā hydrocarbons nui a me nā mea hoʻoheheʻe kemika no nā mea kūʻai aku ʻoihana.Ma mua o kēlā, e heluhelu i ka ʻike kumu e pili ana i ka hana ʻana me mākou:

1. Palekana

ʻO ka palekana kā mākou mea nui.Ma waho aʻe o ka hāʻawi ʻana i nā mea kūʻai aku i ka ʻike e pili ana i ka hoʻohana palekana a me ka hoʻohana ʻana i ka nohona o kā mākou huahana, ua paʻa pū mākou i ka hōʻoia ʻana e hōʻemi ʻia nā pilikia palekana o nā limahana a me nā mea hana ʻaelike i kahi liʻiliʻi kūpono a hiki.No laila, koi mākou i ka mea kūʻai aku e hōʻoia i ka hoʻokō ʻana i nā kūlana palekana kūpono no ka wehe ʻana a me ka mālama ʻana ma mua o kā mākou hoʻouna ʻana (e ʻoluʻolu e nānā i ka appendix HSSE ma nā ʻōlelo a me nā kūlana kūʻai ma lalo).Hiki i kā mākou mau loea HSSE ke hāʻawi i ke alakaʻi i kēia mau kūlana.

2. Keʻano hoʻouna

Hiki i nā mea kūʻai ke kauoha a hāʻawi i nā huahana mai chemwin, a i ʻole hiki iā lākou ke loaʻa nā huahana mai kā mākou hale hana.ʻO nā ʻano kaʻa kaʻa i loaʻa ke kaʻa kaʻa, kaʻaahi a i ʻole ka halihali multimodal (e pili ana nā kūlana kaʻawale).

I ka hihia o nā koi o ka mea kūʻai aku, hiki iā mākou ke kuhikuhi i nā koi o nā moku a i ʻole nā pahu pahu a kau i nā kūlana palekana / loiloi kūikawā a me nā koi.

3. Ka nui kauoha liʻiliʻi

Inā kūʻai ʻoe i nā huahana mai kā mākou pūnaewele, ʻo ka liʻiliʻi liʻiliʻi he 30 tons.

4. Uku

ʻO ke ala uku maʻamau ka unuhi pololei ʻana i loko o 30 mau lā mai ka invoice.

5. Nā palapala hoʻouna

Hāʻawi ʻia kēia mau palapala i kēlā me kēia hoʻouna:

· Bill of Lading, CMR Waybill a i ʻole nā palapala halihali e pili ana

· Palapala hōʻoia o ka nānā ʻana a i ʻole Conformity (inā koi ʻia)

· Nā palapala pili i ka HSSE e like me nā lula

· Nā palapala dute e like me nā lula (inā pono)
