# Canada Tariff Watch

> Free, always-fresh API and data for calculating import duty INTO CANADA. Give an HS code and a country of origin; get the total landed-duty rate — or a range when the code is imprecise — from primary government sources. Tracks new surtax / remission / SIMA orders as they are registered, often ahead of standard tariff tables and customs brokers. Canada-import only, on purpose.

## What it does
- Import duty into Canada by HS code + country of origin: base duty + surtax layers + GST (shown separately, recoverable)
- Returns a low/mid/high range for imprecise HS codes — a business-costing tool
- Does NOT classify products (you supply the HS code); covers Canada only
