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.
Manage your shipping rates in an easy and rapid way. Don't rely on thirds. Do bulk uploads of your rates with just a few clicks. Manage multiple rates from different couriers. Show the shipping cost prior to checkout, so customers won't be surprised and abandon their cart. Calculate rates based on weight and dimensions. Compatible with every country.
- 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
- Manage multiple shipping costs. You can show multuple rates on checkout
- Bulk upload your rates and save time
- Show your shpping costs on the product or cart pages.
