Uranium ores and concentrates — commonly traded as yellowcake (uranium oxide concentrate) — are subject to a specialized regulatory framework that goes well beyond standard customs entry, requiring Nuclear Regulatory Commission (NRC) licensing for import and strict compliance with nuclear non-proliferation controls. The single 10-digit line 2612100000 captures all forms under this heading, with no further US tariff-schedule subdivision. Australia and Namibia are the leading sources entering the US market, reflecting their status as major uranium-producing nations with established export licensing regimes.
