Polysilicon: Movement

How ultra-clean chunks travel double-bagged around Asia

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 tradedmoderate: most Chinese polysilicon is used in China; Wacker, OCI and Hemlock export to Asian wafer makers (indicative)
How it movesChunks in double-bagged clean packaging, granules in sealed containers; shipped by container; semiconductor grade by air in some cases (Conway)
Routes and chokepointsGermany and Malaysia to China, Taiwan, Korea and Southeast Asia; China internal flows from Inner Mongolia, Xinjiang, Sichuan and Yunnan to wafer clusters. HS 280461.
IndiaIndia imports most wafers and some polysilicon from China; HS 280461 figures. HS 280461: India imported $31 thousand (0.0% of world imports, rank 45) and exported $0 thousand (0.0% of world exports, rank 35) (UN Comtrade 2024).
Handling in transitPolysilicon is not dangerous goods; chlorosilane intermediates (TCS UN1295) are highly flammable and water-reactive but are not shipped far.
