The new guidance eliminates ambiguity by allowing “UN” to be used instead of placeholder ISO country codes. However, a 200% duty rate applies in this case.
CBP has issued new guidance for importers on completing Section 232 aluminum reporting when the country of smelt and cast is unknown.
The update, which will take effect on June 28, 2025, requires filers to report “UN” (for Unknown) in ACE when origin information is not available.
This replaces previous instructions, where importers of aluminum derivatives were required to enter an ISO country code—even when the country of smelt and cast was unknown.
CBP had previously directed filers to choose any valid ISO country code other than “US” and permitted them to submit a Post-Summary Correction (PSC) once the correct information became available.
According to the updated guidance, when importers report “UN” instead of an ISO country code for smelt or cast, they must also report the appropriate HTS code (either HTS 9903.85.67 or HTS 9903.85.68).
The entry will be assessed the 200% Section 232 duty, which is the same rate applied to aluminum imports from Russia.
As part of Section 232 aluminum reporting obligations, importers must declare the following using valid ISO codes:
When submitting entries through ACE, importers must report “Y” for the primary and/or secondary country of smelt. Reporting “N” for both fields is not permitted.
For the Importer's Additional Declaration Record Type '07', if either the derivative aluminum primary and/or secondary country of smelt or country of cast is unknown, importers must report ‘UN’ for the ISO country code.
CBP has updated the ACE Entry Summary Create/Update CATAIR (v105) with additional technical details and reporting requirements to support the new Section 232 aluminum reporting procedures.
Moreover, the Entry Summary Error Dictionary now includes two new error codes:
