The Bureau of Customs (BOC) will start imposing the definitive anti-dumping duties on imports of gypsum board from Thailand on February 27.
BOC Management Information Systems and Technology Group Memo No. 05-2026 indicates that the anti-dumping measure has been set in the agency’s Electronic-to-Mobile System.
The implementation of the anti-dumping measure is pursuant to Department of Trade and Industry (DTI) Department Administrative Order (DAO) No. 2025-05, which mandates the levy for five years.

It follows the Tariff Commission’s (TC) order after its investigation established that “dumped imports from Thailand caused material injury to the domestic industry…”
The tariff will be imposed on imports of standard gypsum board, faced or reinforced with paper or paperboard only, classified under AHTN (ASEAN Harmonized Tariff Nomenclature) 2022 subheading 6809.11.000 originating from Thailand.
The dumping margin (as a percentage of export price) for Gypman Tech Co. Ltd. is 8.5%, and for Thai Gypsum Products PCL and all other exporters from Thailand at 9.18%.
DAO 2025-05 said the highest dumping margin will serve as the residual duty or “all other rate” that will be applied to foreign exporters of gypsum boards who did not make themselves known to TC; those that did not cooperate sufficiently during the conduct of formal investigation, and those that are new foreign exporters who have not exported to the Philippines during the period of investigation (POI) from January 2022 to May 2023.
For exporters or producers in Thailand who have not exported standard gypsum board, faced or reinforced with paper or paperboard, to the Philippines from 2019 to September 2024, their individual margins of dumping will be determined following a review. No anti-dumping duties will be levied on imports from such exporters or producers while the review is being carried out.
Excluded from the anti-dumping duties are specialty or technical gypsum boards that are also classified under AHTN 2022 subheading 6809.11.000; and gypsum boards, faced or reinforced with materials other than paper or paperboard that are classified under AHTN 2022 subheading 6809.19.90.
With regard to the cash bond that has been filed and collected as provisional anti-dumping duty pursuant to DAO No. 24-10, and given that the same is in excess of the anti-dumping duty assessed by TC, the remainder or the difference will be returned to the concerned importers upon effectivity of DAO 2025-05.
DAO 24-10 issued in 2024 approved the imposition for four months of provisional dumping duty in the form of cash bond on imports of gypsum board from Thailand.
Under DAO 2025-05, it takes effect after the lapse of the period to file a motion for reconsideration or upon a negative resolution of the motion for reconsideration if one has been filed, and upon issuance of the relevant BOC order implementing the DAO. BOC earlier issued Customs Memorandum Circular No. 10-2026.
Knauf Gypsum Philippines, Inc.—the only manufacturer of gypsum board in the country—filed a petition for anti-dumping duty on imported gypsum board for Thailand on November 24, 2023, alleging that such imports are being dumped in the country and is causing material injury to the domestic gypsum board industry.
The volume of imports of standard gypsum board at dumped prices is not negligible, accounting for 71% of the total Philippine imports of standard gypsum board from 2019 to September 2024.
