Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureScan read-only for missing HS codes, origin, weight, SKUs, categories, and images. Free: up to 100 products and the first 20 issue rows. Pro: up to 10,000 products, the first 1,000 rows, complete exports, five completed scans, and weekly scans with in-app results. Scans support up to 100 variants per product; if a product exceeds that limit, the scan fails without partial results.
DutyLookout 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.
- Scan catalog data for missing HS codes, origins, weights, and SKUs
- Review prioritized issue rows with product links and next actions
- Export cleanup worksheets and track new or fixed issues over time
- 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
