How does silica content in kaolin affect payable weight?

Kaolin buyers pay for the usable clay fraction, so silica acts as dead weight that reduces the net payable mass. A higher silica percentage means you receive less product per tonne shipped, directly lowering the effective value of the lot regardless of the headline price.

Why is the mill test certificate essential for barite?

The mill test certificate provides the definitive chemical assay and specific gravity data required by smelters and drilling fluid manufacturers. Without this document, you cannot verify that the barite meets the density specifications necessary for its intended industrial application, making the lot untradeable.

What happens if radiation screening fails for mica?

Mica is a natural mineral that often contains trace radioactive elements, triggering strict screening protocols at many destination ports. If the radiation levels exceed the import threshold, the entire container is rejected or destroyed, resulting in a total loss of the shipment and freight costs.

How does gypsum density impact container loading?

Gypsum is relatively dense, meaning its weight limit is reached before the container is physically full. This forces you to pay for the full weight allowance even if the box is not visually packed, making the stowage factor a critical calculation for accurate landed cost estimation.

Why does fluorspar pricing expire so quickly?

Fluorspar prices are tied to daily industrial indices that fluctuate with steel and aluminum production cycles. A quote held for more than a few days becomes invalid as the underlying index shifts, requiring immediate confirmation to lock in the agreed valuation.

What role does moisture play in iron ore shipments?

Excess moisture can cause iron ore to liquefy during transit, creating a safety hazard that may lead to vessel refusal. Buyers must ensure the moisture content is within the transportable limit specified by the classification society, or risk the cargo being rejected at discharge.

How does the mineral export licence affect timeline?

South Korea (Republic Of Korea) requires a valid mineral export licence for most ore categories, which must be obtained before loading. This administrative step adds a fixed lead time to the process, so buyers must account for licence issuance when planning their supply chain schedule.
