DutyLookout classifies your catalogue under the US Harmonized Tariff Schedule in two passes. The first works out the tariff subheading. The second reads the 10-digit statistical lines published under it and picks the one that fits, so the last four digits come from the schedule, not the model's memory. A code you already hold is validated and kept, or flagged for review, never replaced without your approval. Duty is arithmetic against a versioned rate snapshot, with no AI involved.

• Two passes: the 10-digit line is chosen from the published tariff, not recalled
• A written rationale and a confidence level on every suggested code
• Codes you already hold are validated and kept, never replaced without approval
• Duty computed by arithmetic against a versioned rate snapshot, with no AI
• Daily tariff monitoring with per-SKU email alerts, included as standard
