Cross-border
Shipping from Canada to the USA
A practical, independent overview of the carriers, customs steps and delivery expectations for parcels moving from Canada into the United States.
Carrier options
Most Canadians ship to the US using one of four networks: Canada Post (with USPS on the American side), Purolator, UPS Canada, and FedEx Canada. Each has strengths — Canada Post is often lowest-cost for lightweight parcels, while UPS and FedEx typically win on express service and business shipping.
Compare head-to-head in the carrier comparison hub.
Customs documentation
Every parcel crossing into the US requires a customs declaration. At minimum you'll need: the sender and recipient details, an accurate content description, a declared value, and the country of origin. Business shipments generally also require a commercial invoice.
Vague descriptions like “gift” or “merchandise” are a common cause of customs delays. Describe what is actually inside the box.
Duties, taxes and de minimis
The US applies duty and taxes based on classification, declared value and country of origin. Thresholds and rules change; always confirm current requirements with US Customs and Border Protection or a licensed broker before shipping commercial goods.
Prohibited and restricted items
Many items can't cross the border, or require special permits — including certain foods, plants, live animals, weapons, tobacco and some cosmetics. Check with your carrier and US CBP before shipping anything you are unsure about.
Tracking cross-border shipments
Cross-border parcels often show a pause when handed to the destination-country partner (for example, Canada Post to USPS). This is normal and typically clears once the receiving carrier scans the shipment.
Returns
US-to-Canada return shipments have their own customs rules — including provisions for returned Canadian goods. Retain your original export documentation to simplify the return.
