# Caesium: Movement

How cesium hides under general chemical headings

Source page: https://www.materialinsights.org/commodities/cesium/movement/

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 cesium, so flows are described from USGS import data. Cesium compounds cross borders under general chemical headings such as other alkali metals (HS 2805.19), iodides, carbonates and nitrates, which carry US tariffs of 3.5% to 5.5%. No reliable data on the origin of US cesium ore imports have existed since 1988. Before 2016, Canada was thought to be the main supplier of ore and refined chemicals. Recent import data point to China and Germany as sources of cesium chemicals. Tailings reprocessed at Zimbabwe's Bikita Mine are shipped to China.

No distinct HS trade code for this commodity, so trade flows are not charted.
