Expanding from Canada into the U.S. market comes with a tax and duty picture that catches most brands off guard. The assumption that Canada-to-U.S. shipping is straightforward because the markets are adjacent is one of the most common and costly mistakes Canadian brands make in their first year of U.S. operations.
If you are trying to:
- Understand what duties and taxes apply when shipping from Canada into the U.S.
- Know how USMCA affects your landed cost and what qualifies
- Figure out whether DDP or DDU is the right structure for your U.S. customers
- Avoid compliance issues that delay shipments and generate unexpected cost
…here is what to get right before you ship your first U.S. order.
What Actually Gets Taxed When You Ship South
Canadian brands shipping into the U.S. face a different duty and tax structure than they’re used to domestically. The key variables:
U.S. customs duty applies to most imported goods and is calculated using the U.S. Harmonized Tariff Schedule (HTS). The rate depends on the product category and country of origin. Many Canadian goods qualify for preferential treatment under USMCA, but that qualification is not automatic — it requires proper documentation and origin certification.
De minimis threshold in the U.S. is currently USD $800. Shipments valued below that threshold clear customs without formal entry or duty payment. For DTC brands shipping individual consumer orders, the de minimis threshold covers most transactions — but it applies per shipment, not per customer, and it does not exempt all product categories.
State sales tax is a separate layer. The U.S. does not have a federal sales tax equivalent to Canadian GST. Instead, 45 states and D.C. levy their own sales tax, with different rates, rules, and nexus thresholds. Canadian brands with significant U.S. sales volume may trigger economic nexus in states where they have no physical presence, creating a registration and remittance obligation.
USMCA and What It Actually Means for Your Products
USMCA replaced NAFTA in 2020 and provides preferential duty rates for qualifying goods traded between Canada, the U.S., and Mexico. For Canadian brands, USMCA can eliminate or significantly reduce duty on goods shipped into the U.S. — but eligibility depends on origin rules that vary by product category.
To claim USMCA preferential treatment, your goods need to:
- Meet the specific rules of origin for their HTS classification
- Be accompanied by a valid certificate of origin or written certification
- Be correctly classified under the U.S. tariff schedule
The practical implication: a Canadian brand shipping apparel, personal care, or consumer electronics into the U.S. may qualify for zero duty under USMCA — but without proper origin documentation and correct HTS codes, they will pay the standard rate regardless.
Get your HTS codes reviewed and your origin documentation in order before you start shipping volume. A single misclassification across a high-volume SKU generates meaningful overpayment at scale.
DDP vs. DDU for U.S. Customers
The same logic that applies to U.S. brands shipping into Canada applies in reverse. DDU creates a poor customer experience when the buyer encounters unexpected charges at delivery. DDP gives the customer a clean, all-in purchase price.
For Canadian DTC brands entering the U.S., DDP is almost always the right structure. Most U.S. consumer orders fall under the de minimis threshold, which means duty is not owed — making DDP straightforward to implement without significant cost impact. For higher-value orders or product categories that do not qualify for de minimis treatment, building duty and tax into the landed price at checkout is still the cleaner customer experience.
State Sales Tax: What Triggers It and How to Handle It
Economic nexus laws in the U.S. mean that selling into a state at sufficient volume creates a tax collection obligation, even without a physical presence. Most states set their threshold at USD $100,000 in annual sales or 200 transactions in the state.
For a Canadian brand in early U.S. expansion, this typically becomes relevant within the first 12 to 18 months. The steps to get ahead of it:
- Register in states where you have crossed or are approaching the threshold. Most states process registrations within a few weeks.
- Use a tax calculation tool integrated with your e-commerce platform to apply the correct state and local rate at checkout.
- File returns on the required cadence — monthly, quarterly, or annually depending on volume and state requirements.
The compliance cost is real but manageable. The penalty cost for non-compliance compounds quickly and becomes difficult to unwind once flagged.
Building a Duty and Tax Strategy That Scales
The brands that handle U.S. market entry cleanly treat duty, tariff, and tax strategy as pre-launch work, not a problem to solve after the first customs hold. The practical checklist:
- HTS codes reviewed against U.S. tariff schedule for your top 20 SKUs
- USMCA eligibility confirmed and origin documentation prepared
- De minimis threshold understood relative to your average order value
- State sales tax nexus monitored from day one
- DDP structure confirmed with your logistics partner
Getting these in place before you start shipping means your U.S. customers get a clean purchase experience, your landed cost is predictable, and your compliance posture is defensible as volume grows.
