CSMS #69100111 · Update to ACE CATAIR Error Dictionary: New Error “F876 DUTY HTS REQUIRES NON-DUTY HTS”

📌 ETDETA brief — importer impact summary (educational)

Brief takeaway: CBP has added a new fatal ACE validation that blocks an Entry Summary line from carrying both a dutiable Auto Part HTS and a dutiable MHDV HTS at the same time.

What changed: According to the notice, CBP posted an updated ACE CATAIR Error Dictionary (V4.9) that creates a new fatal error, F876 "DUTY HTS REQUIRES NON-DUTY HTS." The notice states that when an Entry Summary line contains both a common Auto Part HTS number and a Medium and Heavy-Duty Vehicles (MHDV) HTS number, only one may be a dutiable Chapter 99 HTS; the notice adds it is permissible for both to be non-dutiable CH99 numbers. The notice says the update was deployed to the certification and production environments on June 25, 2026.

Who's affected: The notice cites common Auto Part HTS numbers and MHDV HTS numbers, along with associated dutiable and non-dutiable Chapter 99 (CH99) HTS numbers. Specific product descriptions and countries of origin are not otherwise specified.

What to review:
- Review whether your Entry Summary lines combine an Auto Part HTS and an MHDV HTS, and how CH99 numbers are reported on those lines.
- Confirm with your broker whether only one of the two HTS numbers is being reported as dutiable CH99.
- Check whether your ACE filing software reflects the updated CATAIR Error Dictionary V4.9.
- Confirm technical or reporting questions with your assigned CBP Client Representative or ESAR.
