Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureDutyLookout gives every product in your catalog a 10-digit US HTS code. A first pass works out the tariff subheading; a second picks the statistical line from the lines actually published under it. Each code comes with a confidence score and a plain-English reason. Approve codes in bulk, or let high-confidence ones auto-approve, and they are written to every variant.
This app helps international merchants automate cross-border compliance. By continuously auditing active and historical orders, it identifies product variations that lack mandatory customs details. The app's intelligent database generates matching international HS codes and bulk-populates the missing fields across your product catalog in a single click.
- 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
- Scans active orders to find products missing mandatory customs information.
- Generates accurate six-digit global codes based on product descriptions.
- Updates missing data fields across multiple variants in a single click.
- Generates invoices and packing slips with information needed for customs.
