TariffCatalog

What is TariffCatalog?

TariffCatalog is a free suite of customs-data tools built for ecommerce sellers who need to prepare HS codes, duty estimates, and customs document drafts before shipping internationally. It works directly with product catalogs from Shopify, WooCommerce, Amazon, and custom CSV exports, turning raw product data into review-ready customs inputs. The platform covers the full pre-shipment workflow: finding candidate HS codes, checking low-value shipment assumptions, estimating landed cost, and generating draft documents like commercial invoices and CN22/CN23 forms.

Who it's for

• Shopify store owners who need to map HS codes and country of origin fields from product exports before creating labels or invoices.
• Marketplace sellers on Amazon or WooCommerce who want to flag missing origin data and weak product descriptions across large SKU lists.
• Freelance ecommerce operators and small logistics teams who prepare customs paperwork manually and need printable draft documents for review before filing.

Key features

HS Code Finder

Enter a product description and receive candidate HS codes with confidence labels plus verification questions. This helps you narrow down the correct heading before committing to a code for filing.

De Minimis Calculator

Check whether a low-value shipment may qualify for simplified duty treatment based on destination rules. This is useful for testing assumptions before you quote DDP pricing.

Import Duty Calculator

Estimate customs value, base duty, additional tariff, VAT or import tax, fees, and total import cost. You can choose FOB, CIF, or manual customs value basis, and the output is clearly marked as estimate-only.

Document Generators

Prepare commercial invoice, proforma invoice, packing list, and CN22/CN23 draft data with HS code, origin, Incoterms, line items, and quantity. Printable PDF previews let you review everything before shipment.

What stands out

TariffCatalog turns messy product catalogs into review-ready customs data before you ever quote a shipment.

Most duty calculators stop at a single number. TariffCatalog instead focuses on the catalog-first workflow: you upload a CSV, map SKU, title, origin, and HS code fields, then review candidate codes, confidence labels, missing origin flags, and weak descriptions in one pass. The tool also pairs practical guides—like CN22 vs CN23 and customs value vs declared value—with daily playbooks, so you're not just getting outputs but also learning the reasoning behind each customs decision.

Worth checking out if…

You sell across multiple channels and need to standardize customs data without hiring a broker. If you're tired of manually checking HS codes in spreadsheets or guessing whether a shipment qualifies for de minimis treatment, TariffCatalog gives you a free, structured starting point. It's also valuable if you prepare your own commercial invoices or CN22/CN23 forms and want printable drafts with readiness checks before shipping.
