Shipping Canada to the US Without Getting Wrecked by Duty
If you are a Canadian founder shipping into the US and still packing boxes yourself, the duty side of cross-border is where margin quietly disappears. We have been on your side of the table. We co-founded Tru Earth, scaled it to a spot on the Globe and Mail's Top Growing Companies list with 944% three-year growth, and shipped a lot of product south before we built Breakthrough Studio. This guide is the plain-English version of what we wish someone had handed us early.
Before you read another word, a tool to bookmark: our free Cross-Border Duty + Landed Cost Calculator. Run your real numbers as you go. It makes the rest of this concrete.
This is general information, not customs, tax, or legal advice. Confirm your product classification and duty rates with a licensed customs broker before you rely on any of it.
1. The $800 de minimis is gone (and that changed everything)
For years, one rule shaped cross-border ecommerce more than any other. Under US Section 321, parcels valued under 800 USD shipped to a US consumer cleared without duty. A single direct-to-consumer order under 800 USD crossed the border duty-free, and a lot of Canadian brands built their whole US strategy on it.
That door is closed. The US ended de minimis for all countries on August 29, 2025. It came off Canada and Mexico earlier in 2025 and off China in May, then went worldwide at the end of August. Today, shipments valued at 800 USD or less are subject to applicable duties no matter where they ship from. The direct-to-consumer carve-out that used to save you is gone.
So the old mental model, where small direct-to-consumer parcels cleared free and only bulk commercial inbound drew a duty bill, no longer holds. Now essentially everything crossing into the US can owe duty, the single 40 USD parcel and the pallet of 5,000 units alike. What decides your rate is no longer how the goods cross the border. It is what the product is and whether it qualifies under a trade agreement. That makes the next two levers, CUSMA origin and a duty-deferral hub, more important than they have ever been.
2. CUSMA rules of origin
Now the second lever, and the one most founders underuse. CUSMA, the Canada-United-States-Mexico Agreement, lets qualifying goods enter duty-free.
The word doing the work is "qualifying." A product qualifies based on rules of origin, meaning it was made in Canada, the US, or Mexico with enough qualifying regional content. If your product meets the rule for its category and you have the paperwork to prove it, that commercial shipment can enter the US duty-free.
If your product does not qualify, made largely from components sourced outside North America, for example, it pays the standard duty rate for its HTS classification. HTS is the Harmonized Tariff Schedule, the code that tells customs exactly what your product is and what rate applies.
Two things matter here. First, qualifying is not automatic. You need a CUSMA certification of origin and records that back it up. Second, classification is not a guess. The HTS code you use decides the rate, and getting it wrong costs you in either direction. This is exactly where a licensed customs broker earns their fee.
3. The duty-deferral and hub play
The third piece is about cash flow and speed, and it is the one that changed how we shipped.
When you send a bulk commercial shipment into the US, you typically pay duty on the whole lot as it enters. You have now paid duty on inventory you have not sold yet. Your cash is sitting in a warehouse as boxes.
A strategic duty-deferral hub flips that. You hold inventory in the hub, defer the duty on what you have not sold, and then ship duty-paid to the customer as orders come in. You pay duty closer to the moment of sale instead of all of it up front. Your cash stays in your business longer, and because the inventory is already positioned for fast domestic shipping, delivery times to your US customer shrink.
Smoother cash flow and faster delivery, from the same inventory. That is the play.
A simple worked example
Say you make a personal-care product in Canada and you want to sell it in the US.
A US customer orders one unit for 40 USD and you ship it direct as a parcel. Before September 2025, that parcel cleared duty-free under Section 321. Not anymore. With de minimis gone, even this small direct-to-consumer parcel is subject to duty unless the product qualifies under CUSMA. The question that used to matter only for bulk shipments, does my product qualify, now applies to every order.
Now scale it up. You ship 5,000 units across the border as one commercial shipment to position inventory closer to your customers. The same two paths decide the duty, and they are the same two paths that now apply to your direct-to-consumer parcels too:
- Your product is made in Canada and meets the CUSMA rule of origin for its category. With a valid certification of origin and proper records, that shipment can enter duty-free.
- Your product does not qualify. It pays the duty rate tied to its HTS classification, applied to the full value of the goods.
If you hold that qualifying inventory in a duty-deferral hub, you defer duty exposure on unsold units and ship duty-paid and fast as orders land, instead of tying up cash on day one.
Run your own version of this in the Cross-Border Duty + Landed Cost Calculator and confirm the classification and rates with a licensed customs broker. The example above shows the shape of the decision, not your exact numbers.
The short version
The $800 de minimis ended on August 29, 2025, so direct-to-consumer parcels and bulk commercial inbound alike can owe duty entering the US. Origin and classification now decide your rate on everything. Qualify under CUSMA and keep the paperwork to ship duty-free. Hold inventory in a duty-deferral hub to protect cash flow and ship fast.
