Good day:
It depends what country you live in? Can your supplier give you the HS Code (harmonization code) of that item. If they can, you can call CBSA - Canada, and CPB customs border patrol, and they can let you know what taxes, you can expect. Also point you in the right direction for duties.
You have to pick up the phone and call. If doing this gives you the sinking feeling. Go through a freight forwarder, with a worldwide presence. They will go through all the heavy lifting " ie. customs clearance" and figure all of this out for you.
