Vietnam Anti-dumping Investigation on Prestressed Steel Bars from China – AD24: What Interested Parties Should Know

On July 27, 2026, The Vietnam Ministry of Industry and Trade (MOIT) issued Decision No. 1903/QD-BCT to formally commence the anti-dumping investigation on prestressed steel bars originating from China (Case AD24) 

What the Anti-dumping Investigation on Prestressed Steel Bars Covers

The investigation covers certain prestressed steel bar products originating from China, classified under HS codes 7227.20.00, 7228.20.11, 7228.20.19, and 7229.20.00. 

The decision follows an assessment, carried out under Vietnam’s trade remedy law, of a request dossier that was filed fully and validly by producers representing the domestic industry.

The domestic industry has alleged that prestressed steel bar products originating from China have been dumped into the Vietnamese market, causing significant injury to domestic production.

Next Steps in the Anti-dumping Investigation on Prestressed Steel Bars

The next steps follow Decree No. 86/2025/NĐ-CP dated April 11, 2025, which details certain articles of the Law on Foreign Trade Management concerning trade remedy measures.

After initiation, the Ministry will send a sampling questionnaire to interested parties, namely: (i) producers and exporters of the investigated goods into Vietnam that the investigating authority is aware of, and (ii) the representative in Vietnam of the country or territory that produces or exports the investigated goods. A foreign producer or exporter that does not respond to the sampling questionnaire within the set time limit is treated as a not cooperating interested party.

Where there are many foreign producers or exporters from the same country or territory, or a large number of product types subject to the request, the Ministry may limit the scope of the investigation by sampling.

The Ministry will then send an investigation questionnaire to collect information for the analysis of the allegations, covering: (i) the dumping conduct of exporters from the investigated country, (ii) the injury to the domestic industry, and (iii) the causal link between the dumping and that injury.

Where necessary, and based on the preliminary determination, the Ministry may apply a temporary anti-dumping measure to prevent dumping from continuing to cause significant injury to the domestic industry.

Before finalizing its official conclusion, the Ministry will verify the information provided by interested parties. It will also hold a public consultation so that interested parties can exchange information and present their views before the final conclusion is reached.

Who Should Register as an Interested Party

The Ministry recommends that all organizations and individuals importing, exporting, distributing, trading, or using the investigated goods register as interested parties and provide the necessary information. This helps protect their rights and interests under the law.

How to Register and the Deadline

Interested parties register using the interested party registration form and submit it to the investigating authority within 60 working days from the effective date of the decision attached to the notice.

The form may also be submitted by one of two methods: (i) post or (ii) email.

The deadline to register as an interested party is October 16, 2026.
