Bike shop cross-border tax: USD suppliers, tariffs, and a US-priced internet

Your real cross-border exposure is on the buying side

Several major bike and outdoor brands bill Canadian dealers out of the United States, and Asian manufacturers and component makers add a second layer of foreign-currency purchasing on top of that. The tax question here is not a complicated one — a Canadian corporation buying inventory from a US or overseas supplier does not create a US filing obligation on its own — but the currency exposure is real and ongoing, since a fall order invoiced in USD and paid months later under a dating program can cost noticeably more or less than the number booked at order time depending on where the exchange rate lands.

A shop buying from several distributors at once is effectively running a small foreign-exchange book without necessarily treating it as one. Some shops hold a USD business account to pay these invoices directly rather than converting on the fly through a Canadian-dollar account each time, which can smooth out some of the timing risk, though it introduces its own reconciliation step in the bookkeeping. Either approach is fine — the point is picking one deliberately rather than letting the exchange rate be whatever the bank happened to charge that day.

Tariffs and duty follow the country of origin, not the currency

What a bike, e-bike, or component costs to land in Canada depends on where it was actually made, not which country invoiced you — a frame assembled in the US may qualify for CUSMA preferential treatment with the right origin certification, while the same model sourced through a US distributor but manufactured in Asia pays duty based on that true country of origin regardless of the invoice address. Tariff and trade-remedy actions between Canada, the US, and Asian manufacturing countries have shifted more than once in recent years and can affect bike, e-bike, and parts categories specifically, so landed cost is worth confirming per order rather than assumed to be stable year over year — this is a live file, not a settled one, and we say that deliberately rather than guess at a rate that may already be out of date by the time you read it.

US online competition is a pricing problem, not a filing one

Canadian customers who buy bikes and gear directly from US retailers online are a competitive pressure on your floor, not a tax exposure for your shop — you are not responsible for what a customer chooses to import personally, and any duty or GST due on that purchase is between the customer and the border, not your business. Where it does touch your books is warranty and service: a shop that agrees to service a bike bought online from a US retailer is providing ordinary taxable labour, with no special cross-border treatment, and it is worth deciding in advance whether that policy makes sense for your shop rather than working it out at the counter.

The same logic applies to parts sourced for a warranty or repair job on a US-bought bike — if a customer needs a component your usual distributor does not carry for their model, ordering it yourself from a US parts supplier just makes you the importer for that one part, subject to the same duty and origin rules as any other purchase, nothing more exotic than that.

If you sell into the US yourself

A shop that starts shipping bikes, parts, or accessories to US customers online steps into more familiar cross-border territory — sales to US customers are generally zero-rated for GST/HST purposes, and depending on volume and the states involved, US economic nexus rules can eventually require state sales tax registration. That is a smaller-scale version of the questions our e-commerce clients face, and it is worth a conversation before volume grows rather than after a state notice arrives — most shops that sell occasional parts or gear to a US customer through their website never approach nexus thresholds, but a shop that starts shipping regularly should not assume that will always stay true. The broader Canada-US practice behind all of this is described on our cross-border tax services page, and the domestic side of running the shop is covered on our bike shop bookkeeping page.
