Quartz surface products face 25% within-quota and 50% over-quota safeguard duties

A four-year tariff-rate quota begins for covered quartz surface products entered for consumption or withdrawn from warehouse for consumption on or after August 15, 2026. Within-quota entries face an additional 25% duty and over-quota entries face an additional 50% duty in the first year; the rates step down on August 15, 2027, August 15, 2028, and August 15, 2029, as specified in the annex. The additional duties are cumulative with the underlying Chapter 68 or 70 duty and do not displace applicable antidumping, countervailing, or other duties. (White House)

The measure covers QSP slabs and other surfaces whose silica content exceeds that of any other single material, including fabricated or unfinished countertops, tiles, and similar products, including merchandise finished or fabricated in a third country; quarried granite, marble, soapstone, and quartzite are outside the stated scope. The country-of-origin line is material: Canada, Mexico, Australia, Colombia, the listed CAFTA-DR countries, Israel, Korea, Panama, Peru, Singapore, CBERA beneficiaries, and listed developing countries are excluded and do not count toward the quota, subject to the developing-country thresholds and future revisions described in the proclamation. For a non-exempt product entered within the applicable quarterly quantity, report heading 9903.45.30; for excess quantity, report heading 9903.45.31. (White House)

Post-summary corrections require ACH payment for increased duties, taxes, and fees

Effective August 5, 2026, increased duties, taxes, and fees resulting from a Post Summary Correction must be paid electronically through Automated Clearinghouse. CBP will no longer accept check or cash for those increases. The filer submits the payment authorization through the Automated Broker Interface and must use either the ACH Debit or ACH Credit program. For ACH Debit, CBP sends a preliminary statement, requires one authorization per statement, and generally sends a final statement on the first business day after processing; the account is usually debited two business days after CBP accepts the authorization. For ACH Credit, the transaction must originate at least one day before the settlement date and cannot be reversed once initiated.

The rule reaches filers submitting PSCs that increase duties, taxes, or fees, regardless of whether they pay when the PSC is submitted or wait for CBP to bill the full increase at liquidation. Partial payment is not accepted, and a filer that waits for liquidation cannot submit subsequent PSCs in ACE until the initial PSC is paid. Interest cannot be paid before liquidation; it is due when CBP bills the interest. The 300-day PSC filing limit has an exception only when liquidation remains suspended beyond 300 days after entry and the entry has an associated suspension basis at the time of filing, such as CVD, ADD, AD/CVD, EAPA, or a court injunction.
