Pick a material, a stage and the country to depend less on. The tool lists every other producer in the same source table, how large it is without that country, and what else the atlas knows about it.
Without China, the other listed countries hold 19.6 % of world mining output of graphite.
This is arithmetic on one source table, not a forecast. It leaves out prices, stocks, substitution, new mines and how fast anyone could react.

Concentration among the others (HHIHerfindahl–Hirschman indexA measure of concentration: the sum of the squared percentage shares of all countries. 10,000 means one country produces everything; below 1,500 is usually called unconcentrated.)

Share of world reserves: Reserves, 2025· Export control on record:
HHI is the sum of squared country shares (10,000 = one country). Where the table leaves part of world output unattributed, it is a lower bound.
2.6 % of world output in this table is not attributed to a country and stays outside the calculation.
