📌 ETDETA brief — importer impact summary (educational)

Brief takeaway: According to this CBP notice, importers of certain copper articles will need to report where the copper was smelted and cast when new ACE functionality goes live.

What changed: The notice states that under Proclamation 11021 (issued April 2, 2026), importers must provide CBP the information needed to identify the countries where copper used in covered copper articles is smelted and where the articles are cast. The notice says ACE functionality for accepting these smelt and cast fields deploys to the certification environment on July 16, 2026, and to production on July 30, 2026.

Who's affected: The notice cites certain copper articles covered by Proclamation 11021 and Section 232, imported from all countries of origin except the U.S. Specific HTS codes are not listed in this message; the notice references 91 FR 18201 and CSMS 68253075 for further detail.

What to review:
- Review whether your copper article imports fall within the scope of Proclamation 11021 as described in the referenced Federal Register and CSMS materials.
- Confirm with your broker how to report the primary country of smelt and country of cast, and whether a secondary country may be reported.
- Check the July 30, 2026 effective date and ACE production availability for these reporting fields.
- Confirm your sourcing records can support the smelt and cast country information CBP requires.
