US Tariff Rates on Imports from the United Kingdom
The UK gets a partial Section 232 framework: eligible steel and aluminum melted and cast in the UK can enter under a lower framework rate than the general 50%. Section 122 applies where goods are not excluded; there is no general US-UK FTA post-Brexit.

The UK melt/cast distinction
Proclamation 11021 split the Section 232 steel and aluminum rate by metal-origin: UK-melted and -cast metal qualifies for the 25% rate, while metal of other origin imported through the UK pays the general 50%.
Importers must produce mill certificates showing UK melt and cast to claim the carve-out. CBP has been actively auditing this distinction since the rate diverged.
