Borosil shares jump 5% as DGTR backs duty on Chinese glass

Why Borosil stock moved on Friday

Borosil’s share price rose sharply on Friday after the Directorate General of Trade Remedies (DGTR) issued its final findings in an anti-dumping investigation focused on Chinese borosilicate table and kitchen glassware. The market reaction reflected expectations that duties, if implemented, could reduce the price advantage of imported products in the covered category.

The trigger was the DGTR’s recommendation of an anti-dumping duty on most covered imports from China. The recommendation came as a policy step under India’s trade-remedy framework, where the DGTR investigates dumping and suggests duties, while the Ministry of Finance is the implementing authority.

DGTR’s recommendation on borosilicate table and kitchen glassware

In its final findings, the DGTR recommended an anti-dumping duty of $1,526 per tonne on most covered imports of Chinese borosilicate table and kitchen glassware.

For a qualifying producer, Anhui Deli Glassware Group, the recommended duty was lower at $103 per tonne. The presence of a separate rate for a qualifying producer indicates differentiated treatment within the investigation’s scope.

The article did not provide additional product definitions, investigation dates, or the timeline for Finance Ministry notification for this specific borosilicate tableware case, beyond noting the issuance of final findings and the recommended duty levels.

Borosil share price: intraday levels cited

Borosil shares rallied as much as 5.57% to Rs 274.70 on the BSE following the report.

Later in the session, at 12:25 pm, the stock was trading 1.48% higher at Rs 264.05 on the BSE. These levels highlight a classic intraday pattern seen on policy headlines, where initial moves can cool as traders reassess implications and timelines.

A separate DGTR proceeding: textured tempered glass (TTG)

Separately, the DGTR issued provisional findings in an anti-dumping investigation into Textured Tempered Glass (TTG) imports from China and Vietnam. This investigation was initiated following an application by domestic manufacturer Borosil Renewables.

The notice referenced File No.: 6/31/2025-DGTR. A news item datelined New Delhi, Nov 9 (KNN) said the DGTR’s order was dated November 5 and ran to 40 pages.

What the TTG investigation found about import dominance

According to the provisional findings referenced, Chinese and Vietnamese imports dominated India’s TTG market, accounting for 98% of total imports between February and November 2024.

The DGTR indicated that the proposed duty would be set at the lower of the dumping margin and the injury margin, a standard approach in trade-remedy practice aimed at providing relief without exceeding the demonstrated impact.

The article also stated that the Ministry of Finance holds the final authority on implementation.

DGTR’s approach to China’s market status in the TTG case

In response to industry feedback in the TTG proceeding, the DGTR considered China as a non-market economy under Article 15(a)(i) of China’s Accession Protocol.

The rationale cited was insufficient verifiable data for establishing normal value calculations. This element matters because the methodology used to construct normal value can influence dumping margins and ultimately the level of recommended duty.

Process and stakeholder timeline for TTG provisional findings

The DGTR’s order provided stakeholders a 30-day window to comment on the provisional findings, followed by oral hearings. This step sits within the broader process where submissions and hearings can shape the final findings before a recommendation goes to the Finance Ministry.

Finance Ministry notification: anti-dumping duty on specific solar glass

The article also detailed a Finance Ministry notification imposing anti-dumping duty on solar glass originating in or exported from China and Vietnam.

Key elements cited:

• The duty applies for five years.
• It is effective from December 4, 2024.
• The Finance Ministry notification was dated May 8, 2025.

The duty range mentioned was $170 per tonne to $164 per tonne on textured toughened (tempered) glass meeting specific technical criteria, including:

• Minimum 90.5% transmission
• Thickness not exceeding 4.2 mm
• At least one dimension exceeding 1,500 mm
• Coated or uncoated

The Finance Ministry noted that the measure would remain effective for five years from the date of imposition of the provisional anti-dumping duty (December 4, 2024), unless revoked, amended, or superseded earlier.

Borosil Renewables’ role and industry positioning

The DGTR probe on solar glass followed applications from Borosil Renewables Ltd on behalf of the domestic industry. The article said Borosil Renewables, in a BSE filing, welcomed the decision and stated it would encourage rapid and significant growth in domestic manufacturing of solar glass.

The same set of notes also referenced the broader investigation sequence: initiation on February 13, 2024, preliminary findings in November 2024, and a provisional anti-dumping duty in December 2024 for six months.

Key figures and dates at a glance

Market impact: what is confirmed from the reported data

The immediate market impact in the reported session was visible in Borosil’s intraday move on the BSE, with the stock rising up to 5.57% before paring gains.

On the policy side, the report confirms that duties are being recommended or imposed across multiple glass segments. The DGTR’s role is investigative and recommendatory, while the Finance Ministry’s notification on solar glass demonstrates how recommended duties can translate into enforceable tariffs with defined duration and technical scope.

Beyond these points, the article does not provide revenue, volume, or margin data for Borosil or Borosil Renewables, so the business impact cannot be quantified from the given text.

What to watch next

For the TTG case, stakeholders have a 30-day period to submit comments on the provisional findings, followed by oral hearings, before the process moves toward final findings and Finance Ministry action.

For the borosilicate tableware and kitchen glassware case, the next actionable step typically would be Finance Ministry consideration and notification, but the article only states that DGTR has issued its final findings and recommended duty levels.

Conclusion

Borosil’s stock response followed DGTR’s final recommendation of anti-dumping duty on Chinese borosilicate table and kitchen glassware, with differentiated rates including a lower duty for Anhui Deli Glassware Group. In parallel, the broader trade-remedy backdrop includes ongoing DGTR action on TTG imports and a Finance Ministry notification imposing five-year anti-dumping duties on specified solar glass from China and Vietnam starting December 4, 2024.
