Steps
Confirm the USITC's 1 April 2026 injury determination (2-1 vote) that quartz surface product imports are a substantial cause of serious injury to the domestic industry (Investigation No. TA-201-79)
Review the USITC's 5 May 2026 remedy vote recommending a four-year tariff-rate quota: 140 million square feet annual quota, 25% in-quota / 40% above-quota tariff in Year 1, stepping down one point per year
Confirm Canada, Mexico, Singapore, and South Korea are recommended for FTA exclusion from the safeguard tariff
Check whether a presidential proclamation implementing, modifying, or rejecting the USITC's recommendation has been issued — no proclamation had been issued as of mid-June 2026, with historical Section 201 timing suggesting action within roughly 60 days of the report
Track federalregister.gov's Quartz Surface Products docket for the final USTR/White House action and effective date
Known gotchas
This was a proposed remedy, not yet a final tariff, as of the most recently confirmed status (mid-2026) — do not quote a client a locked-in tariff rate as if it were already in effect
This 2026 safeguard action stacks on top of the existing country-specific AD/CVD orders on China, India, and Turkiye — a slab from an AD/CVD-covered country could face both duty regimes simultaneously
