Section 301 Tariffs on Brazil Imports Take Effect July 22, 2026

USTR imposes 25% Section 301 tariffs on Brazilian imports

Effective July 22, 2026, the Office of the United States Trade Representative (USTR) is imposing 25 percent tariffs on all imports of goods that are the product of Brazil, with certain exemptions, under Section 301 of the Trade Act of 1974. The action was published at 91 FR 45516. CBP issued CSMS #69302472 on July 21, 2026, providing filing guidance for importers, brokers, and filers submitting entries on Brazilian-origin articles.

What this means for importers

The new Section 301 action adds Brazil to the list of countries subject to additional tariff exposure. Key points from the CBP guidance:

• The 25 percent additional duty applies to articles that are the product of Brazil, as defined by applicable country-of-origin rules.
• Certain exemptions exist. Importers must review the Federal Register notice at 91 FR 45516 to determine whether their specific goods qualify for an exemption before filing.
• Entry submissions to ACE must follow the instructions provided in CSMS #69302472 to correctly report the applicable Section 301 chapter 99 HTS provision.
• Goods entered or withdrawn from warehouse for consumption on or after July 22, 2026, are subject to the additional duty. Entries with earlier dates of entry may not be affected, but importers should confirm their entry dates carefully.

ACE certification maintenance window: July 22, 2026

Also on July 22, 2026, CBP has scheduled an extended invasive maintenance window for ACE Certification from 5:00 p.m. ET to 10:00 p.m. ET (CSMS #69297862). This window affects the certification environment. Brokers and filers testing Brazil-related entry formats or other new ACE functionality should plan testing outside of that window to avoid disruptions.

Entry Type 13 mail processing guides also updated

Separately, CBP has published additional implementation guides for the Entry Type 13 (ET13) test in ACE, covering U.S. Mail Processing (INT-057) and the Mail Entry Type 13 Test (CBP-290), per CSMS #69298180. While this is unrelated to the Brazil tariff action, brokers handling mail entries should review the updated guides to stay current with ACE test requirements.

What importers should do

• Review 91 FR 45516 and CSMS #69302472 immediately to identify which Brazilian-origin goods are subject to the 25% additional duty and which qualify for exemptions.
• Update HTS classifications and entry preparation workflows to include the correct Section 301 chapter 99 provision for affected Brazilian goods.
• Audit open purchase orders and shipments already in transit to assess duty exposure for goods entering on or after July 22, 2026.
• Schedule any ACE certification environment testing before 5:00 p.m. ET on July 22, 2026, or after 10:00 p.m. ET to avoid the maintenance window.
