New ACE Validation for Section 232 Import Adjustment Offsets on Automobile and Medium/Heavy-Duty Vehicle Parts — Deploys July 18, 2026
CBP will deploy a new ACE validation on July 18, 2026, for import adjustment offsets related to Section 232 duties on automobiles and medium and heavy-duty vehicle parts; a new CATAIR error code will accompany this change. Importers and filers claiming these offsets must ensure their entry data conforms to the updated validation rules before the deployment date.
We are reviewing the updated CATAIR error dictionary now and will be adjusting our filing templates accordingly — filers claiming Section 232 auto/parts adjustments should expect potential rejections if data is not aligned by July 18. Reach out to us before that date to verify your offset entries.
