Autocatalysts: Movement

Why precious metals fly while catalyst bricks go by road

What this tab covers How it moves between countries: share of output traded, physical form and transport, the largest exporters and importers, main routes, India's trade, and handling rules in transit.

UN Comtrade 2024, reported by each country (exports by exporters, imports by importers), all partners. Some countries (for example Russia and Iran) do not report, so their shares are missing. HS codes can be broader than the tile: check the code before reading a share as the whole market.

How it moves

MeasureFigure
Share tradedhigh for metal; coated bricks often made in the country of vehicle assembly (indicative)
How it movesCoated bricks in crates by road and container; PGMs by secure air freight; spent converters as scrap
Routes and chokepointsPGMs from South Africa and Russia to Europe, China, Japan, the US and India; scrap converters from the US and Europe to refiners in Belgium, the UK, Germany and the US.
IndiaIndia imports all PGMs and some coated catalysts. HS 381512: India imported $201 million (1.8% of world imports, rank 12) and exported $35 million (0.3% of world exports, rank 23) (UN Comtrade 2024).
Handling in transitCoated catalysts not dangerous goods; theft risk for scrap converters.
