What is Vietnam’s AD22 Anti-Dumping Case and Why Now?

On 18 July 2025, Vietnam’s Ministry of Industry and Trade (MoIT) initiated an anti-dumping investigation into colorless float glass from Indonesia and Malaysia (case AD22). The investigated goods are classified under HS 7005.29.20 / 7005.29.90. The case was opened upon a petition from domestic producers alleging dumped imports and material injury. 

The Immediate Action Item: Respond to the Foreign Producer/Exporter Questionnaire in AD22 Anti-dumping Case

Foreign producers and exporters have been issued an official questionnaire and must submit responses by the end of 8 September 2025 (Hanoi time). Submissions must be made through TRAV ONLINE, and the filing is only considered timely after all documents are uploaded. Then, send a signed hard copy (confirmation page) and a USB containing the full submission to the authority’s Hanoi address.   

MoIT’s public notice confirms the deadline and references Notice No. 109/TB-PVTM (1 Aug 2025). The authority emphasizes confidentiality protection under the Law on Foreign Trade Management and warns that non-cooperation or late/incomplete responses may trigger “facts available” treatment.   

Scope Details and Methodology Signals of Vietnam’s AD22 Anti-Dumping Case

Definition: The product is colorless float glass produced by horizontal drawing/float process, without mesh core and without absorbent/reflective/non-reflective coatings; not unprocessed optical glass. 

POI & injury period: Dumping POI (Jul 2024 – Jun 2025); injury period (Jul 2021 – Jun 2025). 

Alleged margins (from petition/decision summary): Indonesia ~60.68%; Malaysia ~23.02% (indicative at this stage; actual rates depend on the investigation). 

How to File Correctly

1. Register and download the pack. Use questionnaire from the authority’s sites/TRAV ONLINE. 

2. Prepare two versions: Confidential and Limited circulation (non-confidential) electronic sets, with proper bracketed redactions and meaningful summaries. 

3. Submit via TRAV ONLINE first; then signed hard copy (confirmation page) plus USB to Trade Remedies Authority of Vietnam.   

4. Audit your sales & cost trails. Align invoice, payment, shipment, and accounting records to the POI; reconcile to financials. (If selected for on-site verification, this is where most submissions crack.) The authority has explicitly reserved the right to verify on site. 

5. Coordinate with importers & end-users in Vietnam. Their questionnaire data (prices/volumes/uses) often corroborate your narrative and gaps can invite adverse inferences. 

6. Register as an interested/related party within the designated window to receive disclosures and participate fully. 

7. If timing is tight, request an extension early. Vietnam practice allows extensions on reasoned requests.

Risks of Non-Cooperation

Failing to respond on time or supplying incomplete/incorrect information can lead the authority to apply “facts available,” which typically results in much higher provisional/final margins than cooperative respondents. The notice is explicit on this point. 

What Exporters Should Prepare

Master product mapping: thickness, sizes, processing, and how your models fit the scope definition. 

Sales databases: POI exports to Vietnam; home-market/third-country sales as required; transaction-by-transaction with price terms and adjustments.

Cost of production (COP): Bills of materials, utilities, labor, depreciation, yield/loss, overhead allocation keys.

Affiliations & ownership: Any links with Vietnam importers or other entities in the chain.

Policy & process memos: Discounts/rebates, freight policies, warranty, and accounting practices (to show consistency).

Verification kit: Index of source records (trial balance, ledgers, invoices, GRNs, payment proofs) and ready for on-site review.

Market/Strategy Watch

Given parallel float glass trade actions in other jurisdictions, multijurisdictional alignment of your data story matters. While each system differs, consistency across filings protects credibility and reduces the risk of adverse inferences.

  Vietnam has officially launched Vietnam anti-dumping investigation AD23 against ceramic and porcelain tiles originating from India. This case, announced through Decision No. 2333/QD-BCT on August 18, 2025, represents a significant trade development for exporters and importers alike.

The Ministry of Industry and Trade (MOIT), through the Trade Remedies Authority of Vietnam (TRAV), has issued a Sampling Questionnaire to foreign producers and exporters, requiring urgent attention. The deadline for submission is September 10, 2025 (Hanoi time).

We refer to Announcement No. 131/TB-PVTM dated August 25, 2025 and Vietnam’s alignment with WTO anti-dumping rules to provide a structured guide on the investigation process, legal obligations, deadlines, and practical strategies that exporters should follow to safeguard their commercial interests.

Background of Anti-dumping Investigation AD23

The Vietnam anti-dumping investigation AD23 concerns certain ceramic and porcelain tiles exported from India to Vietnam. Vietnamese producers alleged that imports were being dumped, thereby threatening or causing material injury to the domestic industry.

Based on preliminary evidence, MOIT initiated the case to determine whether dumping exists and whether trade remedies are warranted.

The period of investigation runs from July 1st, 2024 to June 30th, 2025. Additional years of data may be reviewed to assess trends in injury.

Legal Basis of Anti-dumping Investigation AD23

The investigation is conducted under:

• The Law on Foreign Trade Management (2017);
• Decree No. 86/2025/ND-CP on trade remedies;
• Circular 26/2025/TT-BCT; and
• WTO Anti-Dumping Agreement provisions.

This ensures that Vietnam anti-dumping investigation AD23 is consistent with international standards of transparency, due process, and rights of defense.

The Sampling Questionnaire

The central immediate task for foreign producers/exporters is the Sampling Questionnaire.

• Purpose: To allow TRAV to select representative companies for the full investigation.
• Content: Information on company structure, production, sales, costs, exports to Vietnam, and domestic sales.
• Format: Two versions – a Confidential version and a Limited Circulation version.
• Submission: Must be uploaded via TRAV system and followed by a signed hard copy plus USB submission .

Failure to submit by the deadline will result in the company being treated as non-cooperative, which can lead to reliance on adverse facts available, typically resulting in higher dumping margins.

Timeline and Procedures

The investigation follows a step-by-step process:

1. Initiation – MOIT’s decision to investigate.
2. Questionnaire Phase – September 10th, 2025 as the deadline.
3. Verification – TRAV may conduct on-site verification at company headquarters or production sites to confirm submitted data.
4. Preliminary Findings – MOIT may impose provisional duties within 90–180 days if evidence supports dumping and injury.
5. Final Decision – within 12 months (extendable to 18 months), a final ruling on dumping and anti-dumping duties is made.

For exporters, full cooperation at each stage of Vietnam anti-dumping investigation AD23 is essential.

Confidentiality and Data Protection

Under Article 75 of the Law on Foreign Trade Management, exporters can request confidential treatment of sensitive business information. However, non-confidential summaries must also be provided. Companies should carefully mark confidential sections and prepare parallel public versions to avoid disclosure of trade secrets while still complying with the rules.

Risks of Non-Cooperation

Failure to respond to the Sampling Questionnaire or incomplete/incorrect submissions can result in:

• Application of highest possible dumping margins;
• Loss of procedural rights, including access to case files;
• Reduced ability to challenge findings.

In short, ignoring or mishandling the questionnaire in Vietnam anti-dumping investigation AD23 is likely to lead to a much worse outcome.

Cooperation Guidance for Exporters

Exporters facing Vietnam anti-dumping investigation AD23 should take the following actions immediately:

1. Engage experienced legal counsel familiar with Vietnam’s trade remedy system.
2. Assign internal resources to collect, translate, and verify accounting, sales, and production data.
3. Submit on time via TRAV system, ensuring technical and procedural compliance.
4. Prepare for verification visits by TRAV, which may include plant tours and access to original records.
5. Coordinate with industry associations or other exporters where appropriate, to ensure consistent arguments.

Implications for Importers and Vietnamese Buyers

Importers in Vietnam relying on Indian tile supplies should anticipate potential cost increases. If anti-dumping duties are imposed, landed prices may rise significantly, and supply chain adjustments may be necessary. Monitoring the progress of Vietnam anti-dumping investigation AD23 is therefore equally critical for downstream businesses.

Conclusion

The launch of Vietnam anti-dumping investigation AD23 signals a serious development in Vietnam’s trade remedy practice. Exporters and importers should treat the Sampling Questionnaire and upcoming deadlines with utmost priority. Early, accurate, and cooperative participation is the only effective way to mitigate risks and safeguard market access in Vietnam.

Our firm is closely monitoring the investigation and is ready to assist exporters and importers in preparing submissions, responding to TRAV, and ensuring compliance with Vietnamese and WTO trade remedy rules.

Deadline reminder: Responses to the Sampling Questionnaire must be submitted by September 10, 2025.
