The slowdown in US construction activity is reshaping the balance of power in decorative stones. Quartzite emerges as the big winner, premium marble remains resilient, and granite faces a historic decline.
The Macroeconomic Picture and the Construction “Breather”
During the first quarter of 2026, the United States economy demonstrated remarkable resilience. Real GDP grew at an annual rate of 2.0%, supported primarily by business investments, exports, and consumer spending.
However, the outlook for the construction and building materials sector is significantly more cautious. The slowdown in the housing market, which had already begun to surface in 2025, was clearly reflected at the start of the year, with a decline in building permits, projects under construction, and housing completions.
At the same time, the homebuilder confidence index (NAHB/Wells Fargo Housing Market Index – HMI) dropped significantly to 37–38 points, far below the 45–50 levels recorded in 2024. Low prospective buyer traffic due to high interest rates is forcing builders to operate with less momentum and increased caution, gradually adjusting their orders and inventories to actual market conditions.
Imports: From Stockpiling to Adjustment
The construction downturn dragged down imports of key surface cladding materials. Unlike the first quarter of 2025, when the fear of new tariffs led to preemptive over-buying and high stockpiling, the first quarter of 2026 was characterized by “just-in-time” inventory management and more mature orders, signaling that the market has entered an adjustment phase.
It is worth noting that imports this quarter reflect agreements finalized months prior. Consequently, the escalation of the geopolitical crisis in the Middle East (the war in Iran) and the subsequent rise in energy and shipping costs are not the root cause of the current decline, but rather factors that will exert stronger pressure in the upcoming quarters.
The Great Decade Restructuring (2016–2026)
A comparison of data over the past decade reveals a profound structural shift in US market preferences, which does not merely follow typical economic cycles but fundamentally redefines inter-material competition.
The most dramatic transformation is recorded in the processed granite market, the decade’s major loser. While in Q1 2016 granite imports amounted to $246.5 million and 336,000 tons, ten years later, in Q1 2026, they plummeted to $75.9 million and 121,900 tons. This represents a staggering loss of 69% in value and 64% in volume, indicating a permanent weakening of its competitiveness against materials with a stronger aesthetic identity.
On the flip side, natural quartzite is the absolute ruler of the period. Its imports skyrocketed from $72.4 million in 2016 to $165.9 million in Q1 2026, marking an impressive 129% increase, alongside a 74% rise in imported volumes. Even more striking is that its average import price climbed to $1,127 per ton, now surpassing even marble, certifying a strong and sustainable demand for materials that combine aesthetic luxury with functional durability.
Processed marble followed a much more balanced and mature trajectory. Maintaining its premium character for high-end projects, its import value grew from $235.6 million in Q1 2016 to a historic high of $309.0 million in Q1 2025, before easing to $255.3 million in Q1 2026. Despite this correction, the average import price held strong at $1,098 per ton, while total value remained virtually on par with 2023 levels ($254.1 million), proving the material’s strong resilience during periods of high interest rates.
Finally, ceramic tiles and large slabs remain the undisputed leaders of mass consumption, despite recording a significant drop to $355.8 million in Q1 2026, compared to $488.9 million the previous year. As they are directly tied to mass construction, their imports react faster to mortgage pressures, though their average price remained stable near $640 per ton.
Why Quartzite and Marble are Gaining Ground
The market shift toward natural stone is not just an aesthetic choice; it is directly linked to public health concerns and legal liability. Growing anxieties regarding occupational exposure to respirable crystalline silica and the restrictions being enforced or evaluated internationally for engineered quartz act as major catalysts. Architects and builders are turning back to natural marble and quartzite, as they offer high aesthetic value without carrying the same regulatory and legal risks.
Geographical Map of Suppliers: The Italy – Turkey Duopoly
In terms of international competition, the US market now exhibits greater diversification and complexity, with a clear separation of roles among major suppliers:
-
Italy (Value Leader): Further solidified its position in the premium segment, controlling over one-third (1/3) of total import value, even though its volume share remains lower.
-
Turkey (Volume Leader): Confirms its absolute dominance in terms of quantity, supplying nearly half (50%) of all imported tons, while maintaining a strong presence in value through competitive pricing.
Meanwhile, China continues its long-term market share decline due to the trade environment, whereas countries like India and Vietnam are gradually expanding their footprint, broadening the geographical sourcing base.
Catalysts Determining the Future (2026–2027)
Market performance in the coming months is expected to be shaped by three critical factors:
-
Tariff Policy (Section 301): Proposed USTR tariffs could heavily penalize marble and granite from Brazil. However, because natural quartzite appears to be excluded, this development is expected to further accelerate the shift of Brazilian exports toward quartzite.
-
Geopolitical & Freight Costs: The crisis surrounding Iran is driving up freight rates and risk premiums. This disproportionately affects natural stones due to their high weight-to-value ratio, pushing a portion of the market toward regional supply chains (e.g., Mexico).
-
Labor Market Pressures: The rising cost of compliance with strict silica protection rules, combined with shifting US immigration policies, could limit the availability of skilled fabricators in stone workshops, driving up project execution costs.
Conclusion: The Resilience of Premium
The overarching conclusion is that the US market is not facing a collapse, but rather a selective deceleration. The premium segment—as evidenced by the sustained high prices of Italian and Greek products, as well as the resilience of the over-$2,000-per-ton category—shows remarkable immunity to economic cycles.
For export-oriented companies, the real battle is no longer fought on the ground of the lowest price, but on the level of value, differentiation, material safety, and architectural prestige.
