CBP announced Harmonized System Update 2626, created October 9, 2026, containing Section 232 updates and PGA HTS flagging updates.

This is a U.S. Customs and Border Protection (CBP) Harmonized System Update (HSU) that revises the Harmonized Tariff Schedule of the United States (HTSUS) data used for entry filing. A Section 232 update generally reflects trade measures applied under Section 232 of the Trade Expansion Act, commonly involving products determined to affect national security. The update may also adjust Partner Government Agency (PGA) flags, which indicate when another U.S. agency’s requirements or data may apply.

It typically affects importers, customs brokers, freight forwarders, and other filers whose goods use HTSUS classifications covered by the update. The key issue is not only the product description, but the complete tariff classification and any applicable Chapter 99 provisions, exclusions, quota arrangements, country rules, or PGA reporting indicators. Incorrect classification or missing required information can lead to rejected filings, additional duty liability, delays, or compliance inquiries.

What to check

• Confirm the product’s correct HTSUS classification using its material, function, specifications, and condition—not only its commercial name.
• Check the official Section 232 instructions and the relevant Chapter 99 provisions to determine whether an additional measure, exclusion, quota treatment, or country-specific rule applies.
• Review the entry data and broker instructions for required reporting of applicable secondary tariff numbers and any required duty or value information.
• Check the updated PGA flags and identify whether another agency requires permits, certifications, product data, admissibility review, or electronic messaging.
• Keep supporting records, and ask a qualified customs broker or trade counsel to review uncertain classification, origin, scope, or exclusion questions.
