If you are a producer, tell us what you have and the volumes you can hold. If you are a buyer, send us your specification and annual requirement. We will come back with something concrete either way.
A useful first email from a buyer names the material, the grade or specification, the annual tonnage and the delivery point. A useful first email from a producer names the material, typical and guaranteed assay, monthly availability and the load port.
Anything less and we will simply write back asking for it.
