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.
Apply approved codes to Shopify as you evaluate the app. Upgrade to Catalog Watch to monitor catalog changes, manage review queues, approve classifications in bulk, and lower the cost of classifying your full catalog.
- Two passes: the 10-digit line is chosen from the published tariff, not recalled

- Codes you already hold are validated and kept, never replaced without approval
