CBP issued two quota bulletins on October 20, 2026, one for the 2027 second-quarter Quartz Surface Products tariff-rate quota and one for the third tranche of the 2026 beef TRQ under the "Further Ensuring Affordable Beef for the American Consumer" proclamation. Importers and brokers in these commodity sectors need to review each bulletin for open dates, fill thresholds, and entry instructions before filing.

What changed: two new CBP quota bulletins

CBP's Quota and Agriculture Branch releases commodity-specific quota bulletins to announce the administration of each tariff-rate quota period. Two bulletins published simultaneously on October 20, 2026 affect very different product categories, quartz surface products and beef, but both require immediate attention from importers and brokers who routinely file entries in these chapters.

Quartz Surface Products: 2027 Q2 TRQ details

CSMS 70241036 announces that Quota Bulletin 26-601 for the 2027 Quartz Surface Products second-quarter TRQ has been published on CBP's quota bulletin webpage. The commodity is Quartz Surface Products as classified under HTSUS Chapters 68 and 70 subheadings, Chapter 99 Additional U.S. Note 41, and addressed in the relevant Presidential Proclamation and its annex (Proclamation 11051).

Quartz surface products have been subject to a Section 201 safeguard tariff-rate quota. Each quarterly bulletin specifies the quota quantity, the in-quota and over-quota duty rates, the opening date and time for ACE quota entries, and any applicable prior-import or first-come-first-served procedures. Importers should pull the full bulletin from CBP's quota bulletin page to confirm the exact open date and the HTSUS subheadings covered before preparing entry documentation.

Beef: 2026 Further Ensuring Affordable Beef Tranche 3

CSMS 70240656 announces that Quota Bulletin 26-232 for the 2026 "Further Ensuring Affordable Beef for the American Consumer" Tranche 3 TRQ has been published. The commodity is beef as classified under HTSUS Chapter 2 subheadings and Additional United States Note 3, governed by the relevant Presidential Proclamation and its annex.

This is the third tranche of the beef TRQ for 2026, meaning two earlier tranches have already opened and, depending on fill rates, may be exhausted. Importers of fresh, chilled, or frozen beef should verify whether in-quota quantities remain available and whether their specific HTSUS Chapter 2 subheadings are covered under AUSN 3. Over-quota entries will be subject to the higher Column 1 general rate of duty, so confirming quota availability before filing is essential.

ACE Certification maintenance window: filing impact

CSMS 70245314 notified trade participants of an ACE Certification Extended Invasive Maintenance Window on October 21, 2026, from 5:00 pm to 9:00 pm ET. The Certification environment is used for testing entry transmissions, PGA message sets, and quota filing procedures before submitting to ACE Production. Brokers and software vendors who were conducting pre-filing tests around quota open periods should verify that any test transmissions sent during this window completed successfully.

Lindsey O. Graham Sanctioning Russia and Iran Act: what we know

A Federal Register document published October 21, 2026 addresses implementation of the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026. The notice signals that trade flows involving goods of Russian or Iranian origin, or transactions routed through entities subject to the Act, may face additional restrictions or duty exposure. Importers with supply chains touching either country, or intermediate processors in third countries, should review the full text for covered goods, applicable entities, and effective dates. Denied-party and sanctioned-entity screening should be updated to reflect any new designations that accompany this implementation.

What importers and brokers should do now

• Pull Quota Bulletin 26-601 from CBP's quota bulletin page, confirm the open date, quantity, and covered HTSUS Chapter 68 and 70 subheadings for the 2027 Q2 Quartz Surface Products TRQ, and queue ACE quota entries accordingly.
• Pull Quota Bulletin 26-232 and verify remaining in-quota quantities for the 2026 Beef Tranche 3 TRQ under HTSUS Chapter 2 and AUSN 3 before filing to avoid inadvertent over-quota duty exposure.
• Review the full text of the Federal Register notice implementing the Graham Sanctioning Russia and Iran Act and update denied-party screening lists for any newly designated entities.
• Confirm that any ACE Certification test transmissions attempted during the October 21, 2026, 5:00 to 9:00 pm ET maintenance window completed without error before relying on those results for production filings.
