Each PGM has its own pair of subheadings: palladium unwrought or in powder form falls under 711021, and palladium semimanufactured under 711029, while the equivalent platinum subheadings are 711011 and 711019. The metal identity must be declared precisely, as palladium and platinum carry different duty treatments and market values.

South Africa accounts for the majority of global primary PGM mine output, so labor disruptions, power constraints, or export-policy changes there can tighten global availability rapidly. Importers relying on just-in-time delivery for catalytic-converter or fuel-cell production should monitor South African supply conditions and consider strategic inventory buffers.
