Unlike refined copper cathode, which trades at or near the LME spot price, copper concentrates are priced based on payable metal content minus treatment and refining charges (TC/RC) negotiated between the mining company and the smelter. Importers and smelters also account for deductions for penalty elements such as arsenic, bismuth, or fluorine that complicate smelting.

Copper concentrates are typically shipped as bulk cargo in vessels or in containers, and their moisture content must be carefully managed to stay below the transportable moisture limit (TML) to prevent cargo liquefaction — a significant maritime safety concern. Port receiving facilities must be equipped for bulk unloading, and environmental controls for dust and runoff are standard requirements.
