Comment from Quartz Manufacturing Alliance of America

Summary: The Countertop Manufacturers Association of America (ACMC) supports targeted tariffs and safeguards against imported "cut-to-size" or prefabricated quartz products because they bypass domestic manufacturing. However, the organization opposes broad tariffs or quotas on quartz slabs, arguing that such measures would cause material shortages, price spikes, and instability for the domestic supply chain.
