Canada's counter-tariffs reach low-value US parcels

In force · updated 8 September 2026 · reviewed 23 October 2026 · North America

Since 8 September 2026 Canada has applied surtaxes of 15%, 25% and 50% to C$27.6 billion of US goods, including steel, aluminium, furniture, apparel, appliances, dairy and seafood. CBSA guidance (Customs Notice 26-23) says the surtax applies even to goods that would otherwise qualify for relief under the Postal Imports Remission Order or the Courier Imports Remission Order, so low-value parcels from US retailers are not carved out.

For a parcel A US-origin parcel of covered goods now owes surtax in Canada even below the C$40 and C$150 thresholds, so it must be accounted for and charged.

What to prepare

  • Update Canada-bound landed-cost calculators with surtax by tariff line and origin marking, including for low-value orders
  • Make sure DDP checkouts collect the surtax up front to avoid refused deliveries
  • Check whether US sellers can ship affected goods from non-US stock or Canadian warehouses

Our reading

Removing the low-value carve-out turns a trade dispute into a per-parcel cost for cross-border e-commerce, which favours sellers holding stock in Canada. Expect the lists to move with each round of the Section 338 escalation.
