A new federal trade action is changing the cost of certain imported quartz products, adding to wider cost pressures across the surface industry. The rule is now in place, but its effects on supplier pricing, availability and individual projects will not be one-size-fits-all.
On August 15, 2026, a new federal safeguard measure took effect on certain imported engineered quartz. Since then, suppliers, importers and fabricators across the country have been working quickly to understand what it means for their products and customers. The headline is straightforward: some imported quartz is now subject to a new duty. The reality is more layered. The rate can change depending on how much covered quartz has entered the country, many countries are exempt, and natural stone and porcelain are not included in this particular safeguard.
That distinction does not mean those materials are insulated from separate duties, supplier increases or wider market costs. A separate federal trade action that took effect July 22 added a 25% duty to most imports from Brazil, affecting certain natural stone products while exempting others. This includes some Brazilian granite and marble products, although certain quartzite products were excluded from the additional duty.
These multiple recent trade actions are only part of a much broader cost picture. Suppliers are increasing prices across quartz, natural stone, porcelain and other material categories, including some products that are not directly covered by either measure. Freight, fuel, tooling, equipment and other costs involved in fabrication and service are also continuing to rise. The most important thing to understand is that each federal action began on a specific date, but the overall cost impact is reaching the industry in different ways and at different times.
How we got here
The process began in September 2025, when the Quartz Manufacturing Alliance of America petitioned the U.S. International Trade Commission for relief from rising imports. The Commission then opened a formal investigation under Section 201 of the Trade Act of 1974.
Section 201 is designed to give a domestic industry temporary protection when increased imports are found to be a substantial cause of serious injury. Unlike some trade cases, it does not require a finding that another country engaged in unfair trade practices. During its investigation, the Commission examined import levels, domestic production, market share, financial performance and other conditions across the U.S. quartz industry. It reported that imports increased 78.3% between 2020 and 2024 and represented 88.3% of apparent U.S. consumption in 2024.
The Commission determined that increased imports were a substantial cause of serious injury to the domestic industry and recommended temporary relief. The President then issued Proclamation 11051, establishing the final safeguard measure that took effect on August 15, 2026.
This is not a single flat tariff
The new measure is a tariff-rate quota. In plain terms, that means a set amount of covered quartz can enter the United States at one duty rate. Once imports exceed that shared national limit, additional covered products face a higher rate.
During the first year, approximately 140 million square feet of covered quartz can enter at a 25% duty. Covered imports above that amount face a 50% duty. The quota is divided across four quarters, and unused space from one quarter may carry into the next. Because this is one national quota, no individual supplier or fabricator controls when the higher rate may begin applying. That uncertainty is one reason pricing may continue to develop throughout the year.
The safeguard is scheduled to last four years. The quota grows and the rates decline minimally over time:
| Safeguard period | Approximate annual quota | Within-quota duty | Above-quota duty |
|---|---|---|---|
| Year 1 Aug. 15, 2026 to Aug. 14, 2027 | 140 million sq. ft. | 25% | 50% |
| Year 2 Aug. 15, 2027 to Aug. 14, 2028 | 159 million sq. ft. | 23% | 49% |
| Year 3 Aug. 15, 2028 to Aug. 14, 2029 | 164 million sq. ft. | 21% | 48% |
| Year 4 Aug. 15, 2029 to Aug. 14, 2030 | 169 million sq. ft. | 19% | 47% |
Not every product is affected in the same way
While the safeguard directly covers certain imported engineered quartz slabs and finished products, rather than natural stone or porcelain, that distinction determines only which products are assigned duties under that specific action. A separate federal trade action that took effect July 22 added a 25% duty to most imports from Brazil, including certain natural stone products, while exempting others. Together, these distinctions show why the impact cannot be understood by looking at material categories alone.
The impact reaching suppliers and fabricators is also shaped by existing inventory, sourcing, freight, replacement costs and how each supplier chooses to respond. Some may adjust only directly affected products, while others may change pricing across broader collections, including natural stone, domestic products and porcelain.
Quartz from a number of countries is exempt from the safeguard. These include Canada and Mexico, several U.S. free-trade partners and certain developing countries named in the proclamation. The exemptions can change if imports from an excluded country increase beyond established limits or if the federal government identifies efforts to avoid the measure.
For customers and fabricators, the practical takeaway is simple: a brand name or general material category does not always tell the full story. One supplier may offer products made in several countries, so one color may be affected while another is not. Where the product was manufactured, how it is classified and which trade action applies all matter.
The effective dates are fixed, but the market response is not.
The Brazil action took effect July 22, and the quartz safeguard took effect August 15, but suppliers did not all reflect those changes on the same dates. Some entered the changes with material already in U.S. inventory. Others had shipments in transit or products coming from a mix of covered and exempt countries. Some suppliers have announced new pricing, while others are still evaluating the effects or holding their current pricing for a period of time.
That is why a 25% import duty does not automatically mean an immediate 25% increase on every affected project. The cost that eventually reaches a fabricator can depend on:
- Whether the product is covered or exempt under either action
- Where it was manufactured
- How the product is classified
- When the material entered the United States
- Whether covered quartz imports are still within the national quota
- Other duties already attached to the product
- Freight, warehousing and replacement inventory costs
- How and when each supplier changes its pricing
The new duties may also influence products that are not directly covered. If demand shifts toward domestic quartz, products from exempt countries, natural stone, porcelain or other surfaces, manufacturers and distributors may reconsider pricing, inventory and availability across their collections.
That does not mean every product outside the scope of these duties will increase. It means the wider market response cannot be understood by looking only at the headline duty rates. Any responsible pricing response must consider the overall cost impact that actually reaches the business, rather than applying those percentages broadly across an entire project.
What the industry may see next
It is too early to predict exactly how the market will settle, but several developments are worth watching.
Sourcing decisions may change. Suppliers may place greater emphasis on domestic quartz, products from exempt countries or natural stone classifications that are not subject to the new duties. Customers may also take a closer look at natural stone, porcelain and other surface options.
Pricing may change in stages. Suppliers have different levels of exposure and different amounts of inventory. Updates are likely to arrive at different times rather than through one coordinated industry-wide increase. Suppliers may also decide to handle the combined impacts of these trade actions with broader changes that increase costs on products not directly subject to new duties.
Availability may shift. If demand concentrates around products outside the scope of the new duties, popular colors could face longer lead times or tighter inventory. Other colors and materials may become more prominent as suppliers adjust their offerings.
Domestic production may receive new investment. The purpose of the quartz safeguard is to give U.S. quartz producers time to strengthen their position. The proclamation also allows trade agreements that could include commitments to invest in domestic slab production.
The rules may continue to evolve. The federal government retained the ability to respond to import surges from countries exempt from the quartz safeguard, attempts to avoid the measure and new trade agreements. The scope of other trade actions may also change through future decisions or negotiations.
These are possible market responses, not promises of what will happen. What we can say with confidence is that origin, classification, timing and supplier strategy will all matter, and the industry will need to keep evaluating the effects as real pricing and purchasing information becomes available.
Premier’s perspective
At Premier Granite & Stone, we are evaluating the overall cost impact reaching our business rather than treating the headline duty rates as the sole basis for project pricing. The new trade actions are an important part of that impact, but they are arriving alongside supplier increases across multiple material categories and rising costs in freight, fuel, tooling, equipment and other areas that support the material, fabrication and service behind every project.
These conditions cannot be addressed responsibly by applying the tariff percentages broadly across every material or project. Our approach is to consider the combined impact of the costs and market conditions we are actually seeing while recognizing that different products, suppliers and material categories may be affected in different ways.
Many suppliers are still finalizing their own pricing, and the market will continue developing over the coming months. We will keep evaluating the impact as the picture becomes clearer and remain open about how changing conditions influence our decisions.
We know our customers are managing many of these same pressures in their businesses, and we do not take that lightly. Our commitment is to price our work fairly, communicate changes openly and limit the impact wherever we responsibly can. Every company in the industry will decide how to navigate this change. Our approach is to stay informed, respond thoughtfully and remain transparent about the decisions we make. In a market moving this quickly, a willingness to keep evaluating the response is just as important as the first decision.
