TariffCatalog provides a set of free, catalog-first customs readiness tools for ecommerce sellers — upload product CSV files from Shopify, WooCommerce, Amazon, or custom exports to get candidate HS codes, check missing country of origin, estimate duty inputs, and prepare printable customs document drafts.
What is TariffCatalog?
TariffCatalog is a free web-based platform that helps ecommerce sellers prepare customs data for product catalogs before shipping internationally. It takes product information from CSV exports (Shopify, WooCommerce, Amazon, or custom formats) or manual entry, and outputs candidate HS codes with confidence labels, estimated duty figures, and draft customs documents (commercial invoices, proforma invoices, packing lists, CN22/CN23 forms). The platform is built by TariffCatalog and operates entirely in the browser with local CSV parsing — no data is uploaded to servers.
