Ukupakisha kunye nokuHanjiswa

Ukupakisha oku-1:Ibhandeji yentsimbi ukuze kube lula ukuyiphatha. Iibhloko zomthi okanye i-dunnage zifakwa phakathi kweenqwaba ukuze kuthintelwe ukutshintsha kwezitho ngexesha lokuthuthwa. Unyango lomphezulu (ukhetho): Ukupenda okumnyama, ioyile yokuthintela umhlwa, ifilimu yeplastiki. Iinqwaba ze-galvanized ezitshixwayo ezishushu zinokugqunywa ngefilimu yokukhusela yexeshana ukuze kuthintelwe ukukrweleka kumphezulu. Iipakethe ezenziwe ngokwezifiso zinokubonelelwa.

2 Ukuhanjiswa:Ubude bempahla eqhelekileyo: 6m, 12m. Ifumaneka ngobude obuqhelekileyo. Iza neSea Rail kunye neNdlela Efanelekileyo. Ifanelekile ukuthutha ngolwandle, ngololiwe okanye ngemoto. Ixesha lokuhambisa lidla ngokuba ziintsuku ezili-15-30 emva kokufumana intlawulo, kuxhomekeke kubungakanani kunye neenkcukacha. Ifanelekile ukuthunyelwa kwamanye amazwe kwihlabathi liphela, kunye noxwebhu olupheleleyo (isatifikethi sokuhlola, uluhlu lokupakisha, i-bill of lading).

Amanyathelo okuzikhusela amathathu:Musa ukusebenzisa izilingi okanye iihoko ezingenazo iipadi ukuze zisebenze ngqo kumphezulu wombhobho ukuze uphephe ukuba umbhobho ungaguquki. Gcina kwindawo epholileyo, eyomileyo nengena umoya kakuhle, kuphephe ukugqwala ngaphambi kokuba ufake. Ukuthunyelwa okugqithisileyo nobunzima obugqithisileyo nceda ulandele imigaqo yokuthunyelwa kwempahla yasekuhlaleni.
