CBP Adds Updated ACE Monitoring Reports
On May 6, 2026, CBP issued CSMS #68554727 providing updated operational guidance and ACE reporting functionality tied to the recently published technical corrections for Section 232 aluminum, steel, and copper duties.
CBP revised the Metals HTS List and introduced additional ACE reports designed to help brokers and importers monitor affected entries and CAPE refund activity related to Section 232 measures.
The update follows technical corrections published on April 29, 2026, and includes changes impacting HTS classifications and duty reporting requirements for certain metals products.
Importers and brokers handling affected products should verify HTS classifications and ACE workflows before submitting protests, PSCs, or CAPE refund declarations to ensure reporting aligns with the updated guidance.
Why This Matters
The additional ACE monitoring tools may help importers and brokers:
- Track affected Section 232 entries more efficiently
- Monitor CAPE refund activity
- Identify reporting discrepancies earlier
- Improve internal reconciliation and compliance workflows
Companies with active Section 232 exposure should review the updated guidance and confirm internal reporting procedures align with the revised HTS references and ACE functionality.

What Changed
1. New HTSUS Subheading for Non-Metal Articles
A new subheading has been added to clarify treatment for goods that are classified under affected HTSUS provisions but do not actually contain aluminum, steel, or copper.
- These products are not subject to Section 232 duties
- Importers must use the new Chapter 99 subheading to properly declare eligibility
- This correction prevents unintended duty application on non-metal goods
2. Correction to U.S. Note 16 (Annex IV)
The notice corrects an inconsistency within Note 16, which defines the scope of covered derivative products.
- Removes conflicting language in subpart (e)
- Aligns the tariff structure with the intended product scope
- Ensures consistency across HTS reporting and duty application
3. Effective Date (Retroactive Impact)
These corrections apply to entries:
- Entered or withdrawn on or after April 6, 2026
- This aligns with the effective date of the underlying tariff changes
This means previously filed entries may require review or correction, depending on classification and product composition.
Why This Matters for Importers
While labeled as “technical corrections,” the impact is operational:
- Prevents overpayment of duties on non-metal products
- Requires precise HTS classification and product composition validation
- May trigger retroactive adjustments to entries already filed
- Increases scrutiny on how derivative products are defined and declared
Even minor classification errors could result in incorrect duty application under expanded Section 232 tariffs.
Key Takeaways
- Not all goods listed under affected HTS codes are subject to Section 232 duties
- Proper use of the new subheading is critical to avoid unnecessary tariffs
- Importers should review recent entries for potential corrections or refunds
- Classification accuracy is now even more important under expanded metals tariffs
