Typical Response Time
We Have Two Mining Owners And Government High Level Chief Join Together
We Are Mandate And Shareholder Of All Sources
One From Indonesia 62% Trail 50000mt And 100000mt/per Month Can Accept Cif
One From Mexico Only Fob And Tt Only And Buyer Need Arrange Shippement By Himself And Need Pay The Expoting Tax And The Mine To Port Shipping Fee
62-64% 100000mt/per Month
At Now Had Spot 8million Mt Only 30-45% Iron Ore Need To Arrange To Be Choiced Into 55%-60% And Delived To Shipping From Peru By Fob
We Also Have Several Endbuyer From Chinese Steel Refinery Of State Or Govement Central
So If You Are The Endbuyer Or His Mandate
Pls Send The Loi To Us
our miner was indonesia 62%
we only work on endbuyer or his mandate
if you send the loi to us
price may be LME-?%
can detail to discussion follow procedure
we direct the miner seller of south amreica
only fob payment term accept
100000~200000mt/month
trial order:40000mt~80000mt
sgs:62.25%
if you are endbuyer pls send me the loi/pof
