CBP HSU 2617: Section 301 Forced Labor HTS Updates and FWS PGA Flag Changes

CBP published Harmonized System Update (HSU) 2617 on July 23, 2026. The update carries 124 harmonized tariff records and 379 Automated Broker Interface (ABI) records. Two distinct sets of changes are bundled inside it, and both have practical filing consequences.

Section 301 Forced Labor HTS updates

HSU 2617 includes revisions to HTS codes tied to Section 301 Forced Labor enforcement. CBP has not published the full list of affected codes in the CSMS notice itself, but brokers and importers should treat any affected HTS lines as potentially carrying changed duty treatment or entry-filing requirements. If your product lines fall anywhere near goods previously flagged for forced-labor scrutiny, pulling the updated tariff schedule now, before your next entry, is essential.

U.S. Fish and Wildlife PGA flag changes: FW2 to FW1

Several HTS codes have been reclassified from the FW2 PGA message-set flag to FW1. In ACE, the distinction between FW1 and FW2 controls which data elements and permits are required at the time of entry filing for U.S. Fish and Wildlife Service (FWS) regulated goods. A code moving from FW2 to FW1 changes the filing obligation at the line level. The specific HTS codes affected are listed in a companion notice, CSMS 69247555, which covers the FWS Final Rule amending 50 CFR.

If you file entries covering wildlife, wildlife products, or other FWS-regulated commodities, you need to cross-reference your active HTS codes against the list in CSMS 69247555 before your next ACE transmission. Submitting a filing with the wrong PGA flag can result in holds, requests for additional data, or entry rejection.

ABI record count matters for system validation

With 379 ABI records included in this HSU, trade software and tariff databases need to be synchronized before entries referencing any of the changed lines are submitted. Brokers relying on third-party classification tools should confirm their vendors have ingested HSU 2617 in full.

What importers and brokers should do

• Review CSMS 69357309 and the companion CSMS 69247555 to identify every HTS code your shipments use that is affected by either the Section 301 Forced Labor updates or the FW2-to-FW1 flag changes.
• Confirm your ACE-filing software and tariff database have been updated to reflect all 379 ABI records in HSU 2617 before submitting new entries on affected lines.
• For any FWS-regulated commodity lines shifting from FW2 to FW1, verify that the correct PGA data elements and permit references are included in your entry filings.
• Flag any Section 301 Forced Labor HTS changes to your compliance team for review against open purchase orders and shipments already in transit.
