India Challenges US Safeguard Tariffs on Quartz Products at WTO
New Delhi, India – India has formally initiated consultations with the World Trade Organization (WTO) in response to the Donald Trump administration’s recent decision to impose safeguard tariffs ranging from 25% to 55% on imports of quartz surface products, effective August 15. The move underscores significant concerns within the Indian export sector, heavily reliant on the US market for these specific goods.
On August 14, India formally approached the WTO, seeking consultations with Washington under the WTO Agreement on Safeguards. India asserted a "substantial interest" in the measure and requested access to information provided by the US, an opportunity to discuss the safeguard action, and the protection of its rights under WTO rules. While no date has been finalized, India has proposed virtual discussions at a mutually convenient time.
Significant Impact on Indian Exports
The gravity of the situation for Indian manufacturers is highlighted by the fact that the United States accounted for a staggering 72.5% of India’s quartz surface-product exports in FY2026, according to a Global Trade Research Initiative (GTRI) report. During that fiscal year, India shipped agglomerated-quartz slabs and certain quartz and glass surface products worth $233.3 million to the US, making the industry largely dependent on this single export destination.
Quartz surfaces, engineered stone products made from crushed quartz or silica, resins, and pigments, are widely used for kitchen countertops, bathroom vanities, flooring, and wall cladding. Indian production is primarily concentrated in Gujarat, Rajasthan, and Telangana, with additional manufacturing capacity in Andhra Pradesh, Tamil Nadu, and Karnataka.
Key Indian exporters in this sector include Pokarna Engineered Stone (marketed under the Quantra brand), Marudhar Quartz Surfaces, KalingaStone-linked companies, ARO Granite Industries, Pacific Quartz Surfaces, Camrola Quartz, Esprit Stones, Mahi Granites, Keros Stone, and Quartzkraft, as detailed in the GTRI report.
The report also emphasizes the challenge faced by Indian manufacturers: "Indian manufacturers have designed their slab sizes, patterns, certifications and distribution networks for the large US countertop and home-renovation market, making it difficult to shift quickly to other markets."
Details of the Safeguard Measures and India’s Position
The newly imposed safeguard tariffs will apply to Indian exports of quartz surface products valued at $233.3 million. This action by India does not yet constitute a formal WTO dispute. During these consultations, India could challenge the US assessment of increased imports and alleged injury to domestic producers. It may also seek an exemption, a dedicated quota, or modifications to the safeguard measures.
The US safeguard will remain in force for four years, from August 15, 2026, through August 14, 2030. During the first year, a global quota of 13.006 million square meters will be in effect, divided into four quarterly allocations. Critically, India has not been assigned a specific quota, meaning it will have to compete with other countries covered by the measure for access to the US market.
Imports falling within the quota will incur an additional 25% duty, while shipments exceeding the quota will face a 50% tariff. This means quartz countertop slabs, previously allowed to enter the US duty-free, will now face tariffs ranging from 25% to 50%. For covered glass products, which already carry a 5% tariff, the overall duty burden will rise to between 30% and 55%. These tariffs could be further compounded by existing antidumping and countervailing duties.
Significantly, Canada, Mexico, Australia, South Korea, Singapore, and several other US free-trade partners, along with certain small developing-country suppliers, have been excluded from the safeguard. However, India and China remain subject to the measure.
Cumulative Impact and Future Outlook
Ajay Srivastava, founder of GTRI, highlighted that a substantial portion of Indian exports of these products already face antidumping and countervailing duties in the US. While Pokarna, Marudhar, and 44 other Indian companies that have undergone review currently have a zero antidumping rate, unreviewed suppliers generally face a 1.02% rate. Countervailing duties range between 1.57% and 2.34%, with an "all others" rate of 2.17%. An outlier, Antique Marbonite, received an antidumping margin of 323.12% in an earlier review. The newly imposed safeguard duties will be added on top of these existing company-specific duties.
Srivastava stated, "India may question whether the US established increased imports, serious injury and a clear causal link under WTO rules. It may also challenge the representative period, quota size, absence of an India-specific allocation, cumulative duties and different treatment of excluded suppliers. India’s immediate objective may be an exclusion or negotiated country arrangement, alongside transparent quota administration."
He further added, "Indian producers may also accelerate diversification into Europe and the Gulf, develop lower-silica surfaces and expand domestic demand. If consultations fail, India has preserved its right to pursue further WTO action."
This episode serves as a stark reminder of the risks associated with over-reliance on a single export market. As GTRI concludes, "Indian producers may therefore need to diversify into Europe, the Gulf and other markets, develop lower-silica products and expand domestic demand, while the government builds an early-warning system to respond to foreign trade-remedy investigations before decisions are finalised." The outcome of these WTO consultations will be closely watched by the Indian export industry and trade policy circles.
