Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCross-border shipping means every product needs a correct customs code — that code and its origin decide the duties. Customs Guard scans your catalog, proposes an HS heading and flags Country of Origin gaps — every proposal shows its reasoning, not just a code, so you can judge it instead of trusting it blindly. Track de-minimis threshold changes across the US, EU and UK, and export an audit trail for your broker.
Dutycode automatically assigns HS codes to products in bulk. Extend classifications with EU CN8, UK Commodity Codes, and US HTS Codes. Each assignment includes a confidence score and explanation. Export results to CSV or Excel, or write HS codes directly to product metafields.
