ITC Section 201 Quartz Tariff: Indiana Fabricators Need to Audit Their Supplier Mix Now

The Quartz Manufacturing Alliance of America-a coalition including Minnesota-based Cambria, DalTile (a Mohawk Industries subsidiary), and other domestic producers-has petitioned the ITC under Section 201 of U.S. trade law for a 50% global safeguard tariff on all engineered quartz surface imports, regardless of country of origin.

Here's what makes Section 201 different from the AD/CVD orders you've seen before: it requires no finding of unfair trade practices from any specific country. It targets every import source simultaneously. Prior AD/CVD orders on Chinese, Indian, and Turkish quartz were imposed in 2019 and renewed just last December-and they didn't stop the import surge. Buyers rerouted through Vietnam and Thailand. The market was already running the same play again.

By January 2026, engineered quartz imports had collapsed 61% year over year. Brazilian quartzite-a natural stone product in an adjacent but distinct category-surged nearly 100% over the same month a year earlier, hitting $57 million. That pattern is consistent with buyers prepositioning toward natural stone alternatives ahead of the ruling, though some of that surge likely reflects inventory front-running rather than permanent sourcing shifts.

Natural stone alternatives sit entirely outside whatever tariff the president ultimately imposes. The president has full discretion to adopt, modify, or reject the ITC's proposed remedy-and whatever he decides sets the imposition timeline. If your supplier mix includes engineered quartz-residential construction, kitchen and bath fabrication, countertop supply chains-the time to audit that exposure is today.
