The assessment of countervailing duties by CBP on shipments or entries of this merchandise is subject to the provisions of section 778 of the Tariff Act of 1930, as amended. Section 778 requires that CBP pay interest on overpayments or assess interest on underpayments of the required amounts deposited as estimated countervailing duties. The interest provisions are not applicable to cash posted as estimated countervailing duties before the date of publication of the countervailing duty order. Interest shall be calculated from the date payment of estimated countervailing duties is required through the date of liquidation. The rate at which such interest is payable is the rate in effect under section 6621 of the Internal Revenue Code of 1954 for such period. 7. This instruction to liquidate entries covered by this message does not limit CBP's independent authority, including its authority to suspend, continue to suspend, or extend liquidation of entries addressed by this message. Accordingly, CBP should examine all entries for which this message directs liquidation to determine whether any such entries are subject to suspension, continued suspension, or extension of liquidation pursuant to CBP's independent authority (e.g., Enforce and Protect Act under section 517 of the Tariff Act of 1930, as amended). If entries of subject merchandise covered by this message are subject to suspension, continued suspension, or extension of liquidation pursuant to CBP's own authority, CBP port officials should follow CBP's internal procedures with respect to continuing any suspension, the lifting of suspension, and/or continuing any extension of liquidation for such entries. 8. If there are any questions by the importing public regarding this message, please contact the Call Center for the Office of AD/CVD Operations, Enforcement and Compliance, International Trade Administration, U.S. Department of Commerce at (202) 482-0984. CBP ports should submit their inquiries through authorized CBP channels only. (This message was generated by OIX:CD.) 9. There are no restrictions on the release of this information. Alexander Amdur
