Know the moment a tariff on your codes changes.
HTSAlert watches your HTS codes daily and alerts you when a duty rate changes — with the effective date, governing action, and 9903 subheading for your entry summary.
- Daily monitoring
- We check your HTS codes against the official USITC tariff schedule every morning — rate changes surface within 24 hours.
- Actionable alerts
- Each alert includes the old and new rate, the effective date, the governing action (Section 301/232), and the Chapter 99 subheading for your entry summary.
- Audit record
- Every detected rate change is stored as an immutable, timestamped record — a searchable compliance trail for every code you watch.
