ACE error F884 rejects Section 338 exemptions without a dutiable Chapter 99 number
CBP title: Update to ACE CATAIR Entry Summary Error Dictionary (V53)
What did CBP announce?
CBP posted an updated ACE CATAIR Error Dictionary V53 on CBP.gov. It adds error F884, EXEMPT HTS NOT ALLOWED FOR SECTION 338. The error rejects a Section 338 exemption HTS number on a line that has no appropriate dutiable Chapter 99 number. The error went into the certification and production environments on August 26, 2026.
What is Allied's position?
This error affects only entry lines that claim a Section 338 exemption. We report the exemption only with the dutiable Chapter 99 number that the line requires, so clients do not need to act.
