Dump truck cross-border tax: the border matters when you buy iron, not haul it

Buying a truck at a US auction: the bid is not the cost

US auction sites move a lot of used dump trucks, and the hammer price is where your real cost starts, not where it ends. The purchase converts to Canadian dollars at the actual payment-date exchange rate, then the buyer's premium, transport home, brokerage, any duty and the registration fees stack on top. That full landed figure is the truck's capital cost — the base for CCA and, one day, for recapture when you sell. Book the bid price alone and every one of those numbers is wrong.

Origin and paperwork decide the duty

Duty follows where the truck was built, not where it was auctioned. Kenworths, Peterbilts, Macks and Internationals assembled in the US, Canada or Mexico enter duty-free — but only with a valid CUSMA certification of origin in hand at import; a US auction invoice by itself proves nothing. Without the paperwork, the truck pays the ordinary tariff rate for goods-transport vehicles, which is real money on a six-figure unit. On-road trucks also clear through the RIV program with a federal inspection before Ontario plates them, and admissibility is worth confirming with a broker before you bid, not after you have paid. One age rule works in your favour: vehicles 15 years or older are exempt from RIV entirely — which matters in a market where older iron still earns — though Ontario will still want its own safety inspection before plating. The CBSA import guide walks through the duty and tax mechanics.

The same logic covers the rest of the iron — pup trailers, live-bottoms, spare boxes and attachments bought from US sellers. Each import pays 5 percent GST at the border on the converted value, and a registered hauler recovers it as an input tax credit as long as the customs entry names the business rather than a courier's account.

Once it is home, the file is Canadian

After import day, the truck is just a Canadian asset: heavy freight-hauling trucks generally sit in Class 16 at 40 percent declining balance — worth confirming against how the unit is actually used — and the repairs, tires and fuel that follow are ordinary domestic expenses with ordinary ITCs. Per-load and hourly revenue carries 13 percent HST like any other hauling service. Keeping that engine of loads, fuel and maintenance tied out month to month is the job of our dump truck bookkeeping service, and it is where the fee actually earns itself.

The day a US haul shows up

Occasionally a hauler near Windsor or Niagara gets offered work across the river, and the tax character of the business changes the moment the truck does. Inter-jurisdictional running means IFTA and IRP instead of plain Ontario plates and fuel tax, US-source revenue means treaty filings even when no US tax is ultimately owed, and none of it should be improvised the week the load is booked. The full picture — Article VIII(4), the protective 1120-F, fuel tax by jurisdiction — lives on our cross-border trucking page, and the setup work runs through our cross-border tax practice. If US work is a one-time question rather than a plan, the honest answer is often to pass on the load.
