Kev Sau Npe Ua Raws CaiCov ntawv lo ob hom lus (Lus Askiv + Lus Mev) raug siv nrog cov lus qhia meej txog cov khoom siv, cov lus qhia tshwj xeeb, HS code, pawg thiab tus lej qhia txog kev xeem.
Kev koom tes ruaj khov nrog cov tuam txhab xa khoom xws li MSK, MSC, COSCO ua haujlwm tau zoo hauv kev pabcuam logistics, peb yog qhov koj txaus siab.
Peb ua raws li cov qauv ntawm kev tswj hwm zoo ISO9001 hauv txhua txoj kev ua haujlwm, thiab muaj kev tswj hwm nruj heev los ntawm kev yuav khoom ntim khoom mus rau kev thauj mus los. Qhov no lav cov kav hlau los ntawm lub Hoobkas mus txog qhov chaw ua haujlwm, pab koj tsim kom muaj lub hauv paus ruaj khov rau qhov project tsis muaj teeb meem!
Q: Koj cov kav dej hlau ua tau raws li cov qauv twg rau Central America?
A:Lawv ua tau raws li ASTM A53 Qib B thiab kuj tuaj yeem ua raws li cov qauv hauv zos.
Q: Lub sijhawm xa khoom?
A:45–60 hnub suav nrog kev tsim khoom thiab kev lis kev cai; kev xa khoom sai sai muaj.
Q: Kev pab txog kev lis kev cai?
A:Yog, peb ua haujlwm nrog cov neeg ua lag luam hauv zos los daws cov kev lis kev cai, se, thiab cov ntaub ntawv kom xa khoom tau zoo.
