What the courier actually collects

Two things go wrong on a cross-border parcel and both are structural rather than a matter of looking up the right rate. First, the duty is added to the value before the tax is worked out, so taxing the value alone always comes out short — on a 200 dollar shipment at 6.5 per cent duty and 13 per cent HST the gap is 1.69, small per parcel and the whole margin on a low-value line. Second, there are two thresholds and they are different numbers, so a 100 dollar parcel from the United States pays tax and no duty at all. This page works out both, per shipment.

Logistics & Shipping

Canadian e-commerce sellers and small importers pricing cross-border orders, and the people who reconcile what the courier billed.

How it works

  1. Enter the shipment: reference, what is in it, and the value for duty.
  2. Say how it arrives — courier from the US or Mexico, courier from elsewhere, or postal — because that decides which thresholds apply.
  3. Enter the duty rate for the tariff line and the GST/HST rate for the destination province.
  4. Read what is collected, and how much taxing the value alone would have missed.

What you gain

  • Calculates exactly which customs duty and tax a courier parcel owes based on its real value and origin, so the amount collected at the door isn't a surprise.

Frequently asked questions

What does this tool actually calculate?

It calculates import duty and tax for a single shipment, applying the correct thresholds (e.g., $150 duty / $40 tax for US-Mexico courier) and stacking the tax base on top of the duty amount.

Does it store my shipment data?

No. All values you enter are processed in your browser only and are not saved or transmitted to any server.

Can it handle shipments from any country?

It supports the two main scenarios: courier from US/Mexico (with dual thresholds) and all other routes (postal or courier) using the old $20 threshold for both duty and tax.
