97% of the magnesium used in the EU comes from China.

Omissions

• The 97% figure refers specifically to magnesium metal; Eurostat's broader measure of all magnesium imports into the EU puts the Chinese share at 92%, so the headline percentage is definition-dependent.
• The claim presents an import-dependence figure as a share of magnesium 'used' in the EU; this is a reasonable proxy because EU domestic production is negligible, but it is not a direct consumption statistic.
• The 97% figure is supported by Euronews reporting citing European Commission data; no primary Commission database entry explicitly stating 97% was retrieved within the search limit.
