TariffCatalog

TariffCatalog is a curated suite of free, estimate-only tools designed to help ecommerce merchants, logistics professionals, and customs compliance teams prepare product data for international shipping. Unlike complex, enterprise-grade customs software, TariffCatalog focuses on the critical pre-filing workflow: finding candidate HS codes, checking for missing country of origin, estimating duty inputs, and preparing draft customs documents. The product is built for catalog-first operations, meaning it works directly with product feeds from Shopify, WooCommerce, Amazon, and standard CSV exports. The core value proposition is quality over quantity—TariffCatalog does not replace official customs filings but instead provides a safer, more informed starting point. Users can parse local CSV files locally in their browser, receive candidate HS code suggestions with confidence labels, flag weak product descriptions, and generate printable drafts of commercial invoices, proforma invoices, packing lists, and CN22/CN23 forms. The platform also includes official-source checks, guiding users to verify final classification and tariff treatment against authoritative sources like the USITC HTS, CBP, and USTR. This approach reduces the risk of costly errors before engaging a customs broker or filing with authorities. TariffCatalog is ideal for small to mid-size businesses that need practical, straightforward tools without the overhead of full-scale compliance software.

HS Code Finder with Confidence Labels

This feature helps users identify candidate HS codes for their products by entering a product description or partial code. Results include confidence labels that indicate how well a candidate code matches the product, along with verification questions to prompt critical review before finalizing. The tool is designed to narrow down options efficiently, not to replace professional classification.

CSV Catalog Checker

Users can upload product catalogs in CSV format from Shopify, WooCommerce, Amazon, or custom exports. The tool maps key fields like SKU, product title, country of origin, and HS code, then scans the entire catalog. It flags missing country of origin entries, weak product descriptions, and suggests candidate HS codes for each SKU, enabling bulk preparation before shipping.

Import Duty Calculator

This feature allows users to estimate the total landed cost of an import by inputting customs value, base duty rate, additional tariffs (such as Section 301), VAT or import tax, and fees. It supports FOB, CIF, or manual customs value basis. The output is an estimate-only calculation designed for planning and quoting, not for official filing.

Commercial Invoice Generator

Users can build a draft commercial invoice by entering line items with HS codes, country of origin, Incoterms, quantities, and values. The generator produces a printable PDF preview that can be reviewed and adjusted before finalizing. It also supports proforma invoice and packing list drafts, making it a versatile tool for document preparation.

Preparing a Shopify Product Catalog for International Shipment

An ecommerce merchant using Shopify can export their product catalog as a CSV and upload it to TariffCatalog. The tool scans each SKU, flags any missing country of origin, suggests candidate HS codes, and identifies weak product descriptions. The merchant can then correct these issues and use the duty calculator to estimate landed costs before setting international prices.

Estimating Landed Costs for a New Product Line

A product manager evaluating a new product line from a supplier can use the Import Duty Calculator to estimate the total cost of importing. By inputting the customs value, expected duty rates, and destination VAT, the manager can generate a quick landed cost estimate. This helps in deciding whether the product will be profitable at the intended retail price.

Drafting Customs Documents for a Low-Value Shipment

A small business sending a low-value parcel internationally can use the De Minimis Calculator to check if the shipment qualifies for simplified duty treatment. Then, using the CN22/CN23 Generator, they can prepare a postal customs declaration draft with item tables and a printable preview. This ensures the package has the correct documentation before mailing.

Reviewing a Multi-Component Product for HS Classification

A logistics coordinator handling a product kit or bundle can use the Kit and Bundle HS Review tool. They can input the individual components and the overall product to determine whether it should be classified as a set, kit, bundle, or separate items. This helps in preparing accurate catalog data and invoice lines for customs.

What is the difference between TariffCatalog and official customs filing software?

TariffCatalog is designed for pre-filing preparation and estimation only. It helps users find candidate HS codes, check for missing data, and draft documents, but it does not submit filings to customs authorities. Users must verify all information against official sources like the USITC HTS, CBP, or USTR before finalizing any customs entry.

Does TariffCatalog store my product data or uploaded CSV files?

No. All CSV parsing and data processing happens locally in your browser. TariffCatalog does not upload or store your product catalogs on its servers. This design ensures that your sensitive product and pricing data remains private and under your control.

Can I use TariffCatalog for any country's customs requirements?

TariffCatalog currently focuses on US import requirements, with tools referencing the USITC HTS, CBP, and USTR. The duty calculator and de minimis tool are designed with US rules in mind. While some tools like the commercial invoice generator may be broadly applicable, users should verify against the specific requirements of their destination country.

How accurate are the candidate HS codes suggested by the tool?

Candidate HS codes are suggestions based on the product description you provide. They are not guaranteed to be correct for your specific product. The tool includes confidence labels and verification questions to encourage careful review. Always verify the final HS code with the official tariff schedule or a licensed customs broker.

TariffCatalog offers a free tier that includes access to all six core tools: US HTS Lookup, HS Code Finder, De Minimis Calculator, CN22/CN23 Generator, Import Duty Calculator, and Commercial Invoice Generator. Additional tools like the CSV Catalog Checker, HS Code Validator, and Invoice Consistency Checker are also available at no cost. There is no pricing information provided for paid plans or tiers. The product is currently free to use for preparing customs data before shipping.
