1. Commerce does not automatically conduct administrative reviews of antidumping duty orders. Instead, reviews must be requested pursuant to section 751(a)(1) of the Tariff Act of 1930, as amended, and in accordance with 19 CFR 351.213. 2. Commerce has not received a request for an administrative review of the antidumping duty order for the period and on the merchandise identified below except for the firms listed in paragraph 4. Therefore, in accordance with 19 CFR 351.212(c), you are to liquidate all entries for all firms except those listed in paragraph 4 and assess antidumping duties on merchandise entered, or withdrawn from warehouse, for consumption at the cash deposit rate in effect on the date of entry: Product: Mattresses Period: 12/2/2023-6/30/2025 Country: Burma Case number: A-546-001 3. Entries for the period 06/29/2024 (first day provisional measures are no longer in effect) through 07/04/2024 (day prior to the publication of the ITC final determination), should be liquidated via message 4211403, dated 07/29/2024. 4. Entries of merchandise of the firms listed below should not be liquidated until specific instructions are issued. Continue to suspend liquidation of all entries of merchandise produced and/or exported by the listed firms entered, or withdrawn from warehouse, for consumption during the period 12/2/2023 through 6/30/2025: Company: Glory Home Myanmar Limited Case number: A-546-001-001 Company: Hangtai (Myanmar) Co., Ltd. Case number: No case number was in place for this company during the period of review. Entries may have been made under A-546-001-000, or other company-specific numbers. CBP officers must also examine entries under A-546-001-000, and all existing company-specific case numbers to ensure the continued suspension of liquidation of entries during the applicable period of review for the producer and/or exporter listed above. 5. There are no injunctions applicable to the entries covered by this instruction. 6. Notice of the lifting of suspension of liquidation of entries of subject merchandise covered by paragraph 2 occurred with the publication of the notice of initiation of administrative review for the 7/2025 anniversary month (90 FR 41043, 8/22/2025). Unless instructed otherwise, for all other shipments of mattresses from Burma you shall continue to collect cash deposits of estimated antidumping duties for the merchandise at the current rates. 7. The assessment of antidumping 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 antidumping duties. The interest provisions are not applicable to cash posted as estimated antidumping duties before the date of publication of the antidumping duty order. Interest shall be calculated from the date payment of estimated antidumping 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. 8. Upon assessment of antidumping duties, CBP shall require that the importer provide a reimbursement certification in accordance with 19 CFR 351.402(f)(2) and as described under this paragraph: a. The importer must certify with CBP prior to liquidation (except as provided below) whether the importer has or has not been reimbursed or entered into any agreement or understanding for the payment or for the refunding to the importer by the manufacturer, producer, seller, or exporter for all or any part of the antidumping and/or countervailing duties, as appropriate. Such certification should identify the commodity and country and contain the information necessary to link the certification to the relevant entry or entry line number(s). b. The certification may be filed either electronically or in paper in accordance with CBP's requirements, as applicable. c. If an importer does not provide its certification prior to liquidation, CBP may accept the certification in accordance with its protest procedures under 19 U.S.C. 1514, unless otherwise directed. d. Certifications are required for entries of the relevant commodity that have been imported on or after the date of publication of the antidumping notice in the Federal Register that first suspended liquidation in that proceeding. e. Consistent with 19 CFR 351.402(f)(3), if an importer fails to file the certification, Commerce may presume that the importer was paid or reimbursed the antidumping or countervailing duties. Therefore, if the importer does not provide the certification prior to liquidation (or as provided above), reimbursement of the duties shall be presumed. Accordingly, if there is no certification with respect to the antidumping duty, CBP shall increase the antidumping duty by the amount of the antidumping duty. In addition, if there is no certification with respect to any applicable countervailing duty, CBP shall increase the antidumping duty by the amount of the countervailing duty. Further, if the importer certifies that it has an agreement with the manufacturer, producer, seller, or exporter, to be reimbursed antidumping duties, CBP shall increase the antidumping duty by the amount of the antidumping duty. In addition, if the importer certifies that it has an agreement with the manufacturer, producer, seller, or exporter, to be reimbursed any applicable countervailing duties, CBP shall increase the antidumping duty by the amount of the countervailing duty. 9. 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. 10. 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:DC.) 11. There are no restrictions on the release of this information.
