The Vietnamese Ministry of Industry and Trade (MoIT) has officially issued Decision No. 121/QD-BCT, establishing a definitive anti-dumping duty on wood fiberboard products originating from China and Thailand.
Effective immediately following the January 19, 2026 announcement, this ruling marks the conclusion of a year-long investigation (Case AD21). The Ministry has determined that imported fiberboard is being dumped into the Vietnamese market at prices that cause "significant threat of material injury" to domestic manufacturers.
New Tariff Rates
The duties apply to wood fiberboard products classified under HS codes 4411.12.00, 4411.13.00, 4411.14.00, 4411.92.00, 4411.93.00, and 4411.94.00.
Unlike a blanket tariff, the rates vary significantly depending on the specific manufacturer and their level of cooperation during the investigation.
- China: Duties range from 2.59% to 39.88%.
Note: The maximum rate of roughly 40% applies to uncooperative exporters or those not specifically named in the decision. - Thailand: Duties range from 3.09% to 20.20%.
Why the Duty Was Imposed
The investigation revealed that Chinese and Thai exporters were selling fiberboard in Vietnam at prices lower than their normal value in their home markets. This aggressive pricing strategy forced Vietnamese producers to lower their prices to unsustainable levels, eroding margins and market share.
By imposing this Vietnam anti-dumping duty on wood fiberboard, the government aims to level the playing field and allow domestic producers—such as VRG Dongwha and Kim Tin MDF—to recover.
Impact on Supply Chains
For furniture manufacturers and construction firms in Vietnam who rely on imported raw materials, this decision necessitates an immediate audit of your supply chain.
- Check Your Supplier: Verify if your specific Chinese or Thai supplier is on the list of "cooperative" companies with lower duty rates (e.g., ~2-3%).
- Calculate Landed Cost: If your supplier falls into the "All Others" category, your material costs will instantly rise by nearly 40%.
- Review HS Codes: Ensure your customs broker is correctly classifying your imports. Misclassification to avoid duties is a serious offense that can lead to retroactive penalties.
