How do assay reports for ores differ from material test certificates for processed metals?

Ores require assay reports that detail the elemental content and impurity levels, which determine the value per tonne. Processed metals like steel fines need material test certificates confirming temper, yield strength, and dimensional tolerances. Confusing these documents leads to quotes that cannot be compared because they measure completely different attributes of the material.

What specification is missing from a generic Magnetite Iron listing?

A generic listing rarely states the iron content percentage or the silica and alumina ratios that affect smelting efficiency. Buyers must ask for the specific chemical breakdown because magnetite quality varies significantly by deposit. Without these details, the price per unit of pure iron remains unknown until the lot is tested.

Why does the physical state of steel fines affect freight classification?

Steel fines are fine particles that can shift or become hazardous during transit if not properly secured. Their particle size and moisture content determine whether they are classified as bulk cargo or require special handling. This physical state directly impacts the stowage factor and the insurance premiums charged by freight forwarders.

How does the export documentation for Ecuador differ for ores versus processed metals?

Ores often require environmental clearance and specific geological export permits from the origin country. Processed metals typically need commercial invoices and packing lists that detail the weight and dimensions of each bundle or container. The paperwork chain is distinct because one is a raw resource and the other is a manufactured good.

What goes wrong when comparing quotes for Manganese Ore versus processed steel?

Quotes for Manganese Ore are usually priced per dry tonne based on manganese content, while processed steel is priced per metric tonne or kilogram based on weight and shape. Comparing them directly ignores the value added by processing and the different cost structures of raw extraction versus manufacturing. You must normalize for content and form.

What packing requirement is critical for steel fines leaving Ecuador?

Steel fines must be packed in containers or bulk bags that prevent leakage and moisture absorption. Standard open-top containers may not suffice if the fines are prone to shifting during rough seas. Buyers should confirm the packing method with the seller to ensure the goods arrive intact and do not incur demurrage charges due to improper loading.

Why is the condition of scrap metal different from virgin ore in terms of inspection?

Scrap metal requires visual inspection for contamination, size segregation, and moisture content, whereas virgin ore relies on chemical assay. The variability in scrap quality means that two lots with the same title can have vastly different melting yields. Buyers must request photos or third-party inspection reports to verify the actual condition of the scrap.
