Please take note that:
1) Our method is ADB in GAD, if AR it will be in
GAR.
2) We don’t accept NAR/NCV as basis for
spec/billing; it's only for reference.
3) Price for CIF will be given upon request and
we need destination port for freight
calculation. Bear in mind different shipping
companies have different ship/freight
charges of their own.
