Wollastonite: Movement
How it hides inside a catch-all trade code
What this tab covers How it flows between countries: the largest bilateral trade routes drawn on a world map, 2024 UN Comtrade export and import values with the top exporters and importers by share, plus shipping routes, chokepoints and trade restrictions.There is no separate trade code for wollastonite, so flows are described from USGS import data. It travels under HS 2530.90, a catch-all for mineral substances not elsewhere specified. The United States was a net exporter in 2025 yet still imported, mainly from China and India. Material moves in bags or bulk bags by container, since tonnages are modest. The US tariff on this heading is free.
No distinct HS trade code for this commodity, so trade flows are not charted.
