Anti-Dumping Investigation on Solar Glass from Vietnam: 7 Checks for Exporters

Turkey has opened an anti-dumping investigation on solar glass from Vietnam, China, and Malaysia. The notice ran in the Turkish Official Gazette dated Jun 19th, 2026, No. 33285. For a Vietnam exporter, the first question is whether products, your buyer, or your group sales route is inside the case.

Interested parties have 37 days from the publication date to file their questionnaire responses. 

The First Test Is the Turkey Connection

A Vietnam company should first check whether its solar glass reached Turkey.

A factory in Vietnam may sell to a trader, an affiliate, a regional sales office, or a solar module maker. The export file at the factory may never show Turkey as the buyer.

If the goods reached Turkey through another party, the case can still impact your business. Trace the route before you decide it belongs to the buyer. This is why a trade remedy notice is part of your international trade and tax risk, not a remote customs matter.

What Turkey Is Reviewing

The case covers solar glass from China, Malaysia, and Vietnam, under tariff headings 70.06 and 70.07. The complaint was filed by several Turkish glass producers. The authority is reviewing import data from 2022 to 2025.

For a business team, the practical scope may include solar glass, photovoltaic glass, PV glass, solar panel glass, processed glass for solar modules, tempered glass for solar modules, and safety glass used in solar applications.

This is not a case against every solar product. A company selling batteries, inverters, mounting parts, or EPC services is not automatically covered. A company that makes or supplies the glass inside solar modules should check with care.

The product name on the invoice is only one clue. The better review looks at the technical sheet, the customs code, the buyer use, the shipment record, and how the product was described in sales documents.

A Public Notice May Not Name Your Company

An exporter should not wait to see its own name in the news.

Trade remedy cases target a product from a country. Once the product and the origin fit, a company can become relevant even when no early report names it.

This is common in Vietnam, because the factory, the trader, and the overseas group office each see only part of the deal. One team holds the product file. Another holds the invoice. A broker holds the export papers. The Turkish buyer holds the import notice. For how these cases usually run, our notes on anti-dumping and trade remedy matters in Vietnam give the wider picture.

Seven Checks for Vietnam Exporters

A short exposure review beats a late response. I would start with these seven checks.

Product Check

Confirm whether the company makes, processes, exports, or trades solar glass, PV glass, photovoltaic glass, solar panel glass, tempered solar glass, worked glass for solar modules, or safety glass for solar use.

Tariff Check

Compare the product file with export declarations and invoices. Watch HS 7006, HS 7007, and any related code used on shipments that may have reached Turkey.

Shipment Path Check

Trace direct and indirect sales. Look at traders, distributors, affiliates, group sales offices, and customers who may resell or ship onward to Turkey.

Customer Check

Ask Turkish buyers, importers, and distributors whether they received any notice, questionnaire, or request for information from the Turkish Ministry of Trade.

Document Check

Keep contracts, purchase orders, invoices, packing lists, customs declarations, bills of lading, product sheets, production records, cost files, and buyer emails.

Data Control Check

Make sure sales, accounting, production, logistics, and group offices use the same product and transaction data. Small gaps grow into large problems when a foreign authority asks for proof.

Decision Check

Decide early whether to respond, to coordinate with your Turkish buyer, or to document why you sit outside the case. Where customs codes or export records are unclear, a quick review with customs lawyers in Vietnam helps avoid a wrong first conclusion.

The Main Risk Is Losing Control of Your Own Facts

The risk in this anti-dumping investigation on solar glass from Vietnam is not only a possible duty.

The nearer risk is that the authority may decide the case without your company data if you do not cooperate when cooperation is needed. In plain terms, your own numbers may not be used to explain your prices, your costs, your product differences, and your sales route.

That reaches your pricing and your customer trust. A Turkish buyer may ask for a plan before any final duty is set. If you cannot answer, the buyer may look for another source. A company with clear records keeps its options. A company with scattered records loses them.

The Deadline Is 37 Days from Publication

Interested parties have 37 days from the Jun 19th, 2026 publication date to submit their questionnaire responses to the Turkish Ministry of Trade. A company that receives a direct notice should still confirm its own date from that letter, because direct service can change the count.

What Management Should Not Do

Management should not assume the case is harmless because the company is not named.

Management should not leave the file only with the sales team. Sales may know the buyer, but accounting, customs, and production hold the data that will be needed.

Management should not send unreviewed statements to buyers or to the authority. A fast wrong answer creates a larger problem than a careful answer sent after the records are checked.

Management should not ignore indirect exports. This is where many Vietnam factories underestimate their exposure.

When a Company May Be Outside the Case

A company may be outside the case if it does not make or sell the relevant solar glass, has no Turkey shipments, and has no indirect Turkey route through traders, affiliates, or customers.

Even then, document the conclusion. A short internal note on product scope, shipment review, and customer check protects you if a buyer or a group office asks later. If the answer is unclear, a limited review first is the safer step.

FAQs on the Anti-Dumping Investigation on Solar Glass from Vietnam

Q1: Is the anti-dumping investigation on solar glass from Vietnam already a duty?

No. It is at the investigation stage. A final duty has not been set.

Q2: What product should Vietnam companies check first?

Solar glass, photovoltaic glass, PV glass, solar panel glass, processed glass for solar modules, and glass under or near HS 7006 and HS 7007.

Q3: Does the case cover all solar panels from Vietnam?

No. The case is about solar glass. A module maker should check the glass part and its supply chain, but the case is not a case against every solar product.

Q4: Does indirect export to Turkey matter?

Yes. If the goods reached Turkey through a trader, an affiliate, a distributor, or a group sales office, the case may still reach the Vietnam producer or exporter.

Q5: What happens if a relevant exporter does nothing?

The authority may rely on the information available to it, and the company may lose the chance to explain its own data. That tends to mean a weaker outcome and more customer pressure.

Q6: Who should manage the file inside the company?

One senior person should hold the file and coordinate sales, accounting, production, customs documents, group offices, Turkish buyers, and outside advisers.

Conclusion

The next step is a short exposure review. A Vietnam company making solar glass, PV glass, solar panel glass, HS 7006, HS 7007, or Turkey sales should check product scope, shipment path, documents, and the deadline now.
