Investigation Initiation Date: 27 July 2026
Product under Investigation: Certain prestressing steel bar products originating from China
HS Codes: 7227.20.00, 7228.20.11, 7228.20.19, and 7229.20.00
First Key Deadline: 03 August 2026 (expected deadline for submission of the sampling questionnaire, subject to MOIT’s official schedule)
Why Should You Act Now?
This investigation may result in the imposition of provisional and definitive anti-dumping duties on imports of the investigated products from China.
Should anti-dumping duties be imposed, Chinese exporters may face significantly higher import costs in the Vietnamese market, reducing the competitiveness of their products and potentially affecting existing contracts, future orders, and long-term business relationships with Vietnamese customers.
For exporters with substantial sales to Vietnam, failing to participate in the investigation from the outset may result in the loss of opportunities to:
- Demonstrate their actual dumping margin;
- Clarify the scope of products exported;
- Protect confidential business information;
- Minimize the risk of being subject to adverse or punitive duty rates.
Key Information
The investigating authority is the Ministry of Industry and Trade of Vietnam (MOIT), which is responsible for conducting the investigation and issuing the final determination in Vietnam’s trade remedy proceedings.
According to the initiation decision, the investigation aims to determine whether imports of certain prestressing steel bar products from China are being dumped into the Vietnamese market and whether such imports have caused or threaten to cause material injury to Vietnam’s domestic industry.
The precise product scope will continue to be clarified during the investigation through the public case file, the Product Control Number (PCN) system, and the questionnaires issued by MOIT.
Participation in the Investigation
All interested parties, including foreign manufacturers, exporters, importers, industry associations, and other stakeholders, may participate in the investigation by registering as interested parties with MOIT and submitting comments, factual information, legal arguments, and supporting evidence.
Key Investigation Timeline
| Event | Expected Deadline |
| Initiation of investigation | 27 July 2026 |
| Issuance of Sampling Questionnaire | No later than 3 August 2026 |
| Deadline for submitting Sampling Questionnaire | No later than 20 August 2026 |
| Selection of sampled foreign manufacturers/exporters | Expected: 30–31 August 2026 |
| Issuance of Main Questionnaire | Expected: 10 September 2026 |
| Deadline for responding to the Main Questionnaire | Expected: 17 October 2026 (may be extended for up to 30 days) |
Note: In practice, MOIT generally selects three to five of the largest foreign producers/exporters for individual examination and requires them to complete the full questionnaire. Foreign producers/exporters that submit the sampling questionnaire on time but are not selected for individual examination are generally assigned the weighted-average anti-dumping duty calculated based on the margins determined for the selected cooperating respondents.
By contrast, foreign producers or exporters that fail to submit the sampling questionnaire within the prescribed deadline are typically treated as non-cooperating interested parties and may be subject to the highest anti-dumping duty determined in the investigation.
What You Should Do
All foreign manufacturers and exporters of the investigated products are strongly encouraged to participate in the investigation from its earliest stage.
Specifically, companies should:
- Register as an interested party with MOIT before 16 October 2026;
- Closely monitor and respond to the Sampling Questionnaire within the prescribed deadline;
- Prepare all necessary information and supporting documents for the questionnaire responses.
Failure to cooperate fully with the investigating authority may result in the application of Adverse Facts Available (AFA), which could lead to substantially higher anti-dumping duty rates.
