Requires the Commissioner, in the case of an affirmative preliminary determination, to: (1) suspend liquidation of each unliquidated entry of the covered merchandise and extend the liquidation of covered merchandise entered before such determination, (2) review and reassess the amount of bond or other security required to be posted for each entry of covered merchandise, (3) require the posting of a cash deposit for each entry, and (4) take other appropriate measures to ensure the collection of any duties that may be owed on covered merchandise.

Requires the Commissioner, in the case of an affirmative final determination, to: (1) suspend or continue to suspend liquidation of each entry of covered merchandise and extend the liquidation of covered merchandise entered before such determination, (2) notify the administering authority (Secretary of Commerce or other responsible U.S. officer) of the determination and request identification of the applicable antidumping or countervailing duties or cash deposit rate for such entries, (3) require the posting of cash deposits and assess duties, (4) review and reassess the amount of bond or other security required to be posted for covered merchandise entered on or after the date of such determination, and (5) take appropriate additional enforcement measures.

Requires the administering authority to apply the highest applicable cash deposit or antidumping or countervailing duty in cases where the producer or exporter of covered merchandise is unknown.

Applies the amendments made by this Act to goods from Canada and Mexico.

Requires the Commissioner, to the maximum extent practicable, to ensure that CBP employs and assigns sufficient personnel to prevent the entry of covered merchandise in a manner that evades antidumping and countervailing duty orders or findings.

Requires the Secretary of Homeland Security (DHS), the Commissioner, and the Assistant Secretary for U.S. Immigration and Customs Enforcement (ICE) to assess and properly allocate the resources of CBP and ICE to improve efforts to investigate and combat evasion.

Directs the Comptroller General to report on: (1) efforts to prevent the entry of covered merchandise into the U.S. customs territory through evasion, and (2) the estimated amount of duties that could not be collected on covered merchandise that entered U.S. customs territory through evasion during FY2011-FY2012 because the Commissioner did not have the authority to reliquidate the entries of such merchandise.
