CBP has pushed two Harmonized System Updates into ACE, HSU 2623 and HSU 2624, that change how Section 232 and Section 338 Canada duties are coded and assessed. A separate CBP notice also confirms that the annual customs broker permit user fee will increase to $190.88 beginning October 1, 2026. The links in this article go to the primary documents: the proclamations, Federal Register notices, and official CBP messaging themselves. Read the source.

What changed in ACE: HSU 2623 and HSU 2624

On September 9, 2026, CBP released HSU 2623, a large update containing 83 harmonized tariff records and 450 Automated Broker Interface (ABI) records. Two days later, on September 11, 2026, CBP released HSU 2624, a narrower update carrying 6 harmonized tariff records and 18 ABI records. Both updates are now live in the Automated Commercial Environment (ACE), and filings made against affected HTS subheadings will be processed under the revised parameters immediately.

Section 232 updates in HSU 2623

HSU 2623 is driven by Section 232 tariff changes. CBP's CSMS message directs readers to CSMS # 69738151 for the underlying operational detail. Brokers and importers filing entries on goods subject to Section 232 duties, including steel and aluminum derivatives, should verify that their ACE filing software has pulled the updated ABI records. Mismatched HTS classifications or stale tariff codes in a broker's system can result in incorrect duty assessment or entry rejection. Cross-check your classification against the current Harmonized Tariff Schedule to confirm alignment with the 83 updated records.

Section 338 Canada scope changes in HSU 2624

HSU 2624 implements a White House proclamation that modifies the scope of products of Canada subject to Section 338 additional duties. Those duties were originally imposed to offset Canadian measures that discriminate against U.S. alcoholic beverage commerce and were first published at 91 FR 46639 on July 23, 2026. The new proclamation, referenced in the CSMS # 69980710 message, modifies the original Annex, meaning the list of covered Canadian goods has changed. Importers of Canadian alcoholic beverages, or U.S. exporters whose Canadian customers are retaliating with purchase restrictions, should review the revised Annex at the White House website to determine whether their products are newly included in or removed from scope.

Pork assessment rate reduction in HSU 2623

HSU 2623 also carries a non-tariff update: a decrease in assessment rates for live porcine animals and pork products collected under the Pork Promotion, Research, and Consumer Information Order (the "Pork Checkoff"). Importers of live pigs and pork products will see a lower importer assessment applied at the time of entry. Verify with your entry software vendor that the new rate is reflected before filing post-September 9, 2026 entries.

Customs broker permit user fee increase effective October 1, 2026

Separately, CSMS # 69847323 confirms that CBP is adjusting COBRA user fees for Fiscal Year 2027. The customs broker permit user fee will increase from $185.38 to $190.88, pursuant to the General Notice published at 91 FR 48398 on July 31, 2026. Any broker permit issued on or after October 1, 2026 is subject to the new $190.88 fee. This is a routine annual COBRA adjustment, but the payment deadline coincides with the start of the federal fiscal year, so firms managing multiple permits should budget accordingly.

Required actions for importers, brokers, and compliance teams

• Update ACE filing software to incorporate the 450 ABI records from HSU 2623 and the 18 ABI records from HSU 2624 before submitting entries on Section 232 or Section 338 Canada goods.
• Review the revised Section 338 Canada Annex (modifying 91 FR 46639) at the White House website to confirm whether your Canadian alcoholic beverage products are in or out of scope under the updated proclamation.
• Confirm the new pork assessment rate is reflected in your entry preparation system for live porcine animals and pork product shipments filed after September 9, 2026.
• Budget $190.88 per broker permit for any permit issued or renewed on or after October 1, 2026, per 91 FR 48398.
