ILeta yoMyalelo woMhambisi (i-SLI) luxwebhu oluyimfuneko olukhutshwe ngumthengisi, ukhokela umthumeli wempahla okanye umthwali ekulawuleni nasekuthuthweni kwempahla. Kumxholo we-US, i-SLI inyanzelekile kuzo zonke iimpahla ezithunyelwa ngaphandle ezivela e-US kwaye kufuneka zigqitywe ngaphambi kokuqokelela iimpahla, iphinda isebenze njengoxwebhu lokugunyazwa kumthengisi wempahla ukuba asebenze njengommeli womthumeli wolawulo lokuthumela ngaphandle kunye neenjongo zamasiko, kuquka ukusebenzisa iindlela ze-elektroniki ezifana ne-Automated Export System (AES) ukuhambisa i-Electronic Export Information (EEI).
I-SLI ibalulekile ekuthotyelweni kwemimiselo kwaye ngokuqhelekileyo ibandakanya iinkcukacha ezinjengomthumeli kunye nolwazi loqhagamshelwano lomthumeli, ukuhanjiswa kwempahla, i-Incoterms, imilinganiselo kunye nobunzima bokuthunyelwa, inkcazo yempahla, kunye neekhowudi ezifanelekileyo ezifana ne-HS kunye neenombolo ze-UN, apho kufanelekileyo.
