In July 2026, the U.S. imposed a Section 201 safeguard tariff-rate quota (TRQ) on imports of Quartz Surface Products (QSP), effective August 15, 2026 — and the stakes are real. Every entry within quota clears at the in-quota duty rate. The moment that tranche's prorating threshold is crossed, the rate doesn't step up gradually — it jumps, immediately, on every unit that follows. There's no grace period, and CBP gives no advance warning beyond the daily bulletin itself.
Quota periods reset regularly, and CBP does publish fill data every day — but it's a dense government feed that's easy to miss, and it tells you nothing about where the pace is headed. This tracker turns that raw data into a daily signal, so you see the threshold coming days in advance, instead of finding out your duty rate just doubled.
In-quota duty: 25% · over-quota duty: 50% (Year 1). The quota year runs Aug 15 to Aug 14; annual volumes rise and duty rates decline in Years 2–4 through the safeguard's expiration in August 2030.
This tool is for informational purposes only and does not constitute legal, customs, or trade compliance advice. Fill rates, burn rates, and threshold projections are estimates based on published CBP quota data and recent entry pace — they are not guarantees of when a tranche will close or prorate. Always verify current quota status directly with U.S. Customs and Border Protection and consult a licensed customs broker or attorney before making entry timing decisions.
