How this was calculated

The maximum exposure includes AD/CVD cash deposits AD 372.81% (A570036) + CVD 25.93% (C570037). AD and CVD from the same investigation are added together. The 4 case families cover mutually exclusive goods, so the family with the highest total is used. The all-others rate is shown; the actual rate follows the exporter or producer and each order's scope, and deposits are not final duties.
