Whether you’re a seasoned global seller or just starting out, this tool can save you time, money, and compliance headaches.

What Is TariffGuide.ai?
TariffGuide.ai is a new feature from Shopify that uses AI to help merchants easily find the correct U.S. Harmonized System (HS) code and estimate duties for their products. It works by letting you type in a product description and then instantly returning:
- A relevant HS code
- An estimated duty rate
- All in plain English
This means no more manually digging through customs websites or guessing with suppliers. It’s a huge step toward making cross-border e-commerce more transparent and predictable.
How to Use TariffGuide.ai on Your Shopify Store
In the search bar, enter a clear, specific description of your product. For example:
- “Women’s canvas backpack”
- “Smartphone tripod stand”
- “Reusable glass water bottle”
The AI tool will provide:
- The U.S. HS code
- An estimated duty percentage or fee
This allows you to set pricing or calculate total costs more confidently.
