A Section 201 safeguard took effect on 15 August 2026 for quartz surface products under HTS 6810.99.00.20, 6810.99.00.40 and 7020.00.60.00 (Proclamation 11051).
It is a tariff-rate quota, so there are two rates: 25% within the quota and 50% above it. Which one applies depends on whether the quarterly quota is still open when your entry is filed, and that is not something we can know from an HTS code and a country of origin.
So we do not guess. On these lanes `summary.total_resolved_ad_valorem_rate` is now `null`, and `rate_conditional.alternatives` carries both rates with their conditions. If your integration totals our response, it will need to read that block rather than the summary. The rates step down each year: 23%/49% from August 2027, then 21%/48%, then 19%/47%.
Most origins are exempt. The proclamation excludes 124 countries and territories, including Canada, Mexico, South Korea, Australia, Israel, Singapore, Brazil and the CAFTA-DR and Caribbean Basin parties. Those lanes are unchanged.
If you ask about an 8-digit heading that spans both covered and uncovered lines, such as 6810.99.00, we return a normal total and show the safeguard as advisory, because whether it applies depends on the 10-digit line your goods classify to.
We were late: the safeguard was in force from 15 August and our answers did not reflect it until 16 August. Lookups on these three codes in that window came back too low. If you priced shipments from them, re-run them.
