US de minimis for Canada: what changes for webshop orders?

If your checkout still says “no duties below $800,” that promise needs reviewing. The old threshold was a shortcut for small commercial imports. Its removal means a low selling price is no longer enough to establish duty-free treatment. Your shop needs a product decision and a delivery decision, rather than one country-wide checkbox.

This guide is for a Canadian business selling physical goods to American customers. Official guidance and the AirPost rate page were checked on October 14, 2026. The focus is which decisions belong in your order workflow; a tariff must be confirmed for the exact goods and entry date.

Does a small order still cross the border without an assessment? #

The February 2026 continuation order maintained the suspension across origins and transport methods for covered articles. It distinguishes international postal handling from other entry procedures. A courier parcel and a postal parcel can therefore share a low merchandise value while needing different customs processing.

Do not read that as “every product now has the same duty.” An exemption, a preferential rate, an additional tariff and an admissibility restriction answer different questions. Your carrier or broker needs enough information to identify the applicable provisions. Keep the product specification, origin evidence and submitted value together so you can explain a particular assessment instead of debating a general shipping headline.

Why does CUSMA no longer mean that every charge disappears? #

The current Canadian government explanation says compliant goods remain exempt from Section 301 tariffs, while Section 338 tariffs have no equivalent CUSMA exemption. It also identifies sectoral measures that require separate treatment. A valid origin certification is useful evidence, but its scope is narrower than a promise of zero landed charges.

That distinction changes how you approve a US product listing. First determine whether the goods qualify as originating. Then ask which preference is being claimed and which additional provisions still apply. Keep the answers separate in your product record. A customer service agent should be able to explain why a qualifying product can still attract a charge without suggesting that the certificate was necessarily rejected.

Avoid copying the tariff percentage from an older article into every checkout. The legal basis and product coverage have changed during 2026. A useful review asks for the tariff provision, its effective date, any exclusion and the reason it applies to your particular item. Save that review with the product version; a supplier changing materials or manufacturing location can make an earlier conclusion unreliable.

Does Canada Post handle preference in the same way as a courier? #

The Trade Commissioner Service’s current tariff resource explicitly distinguishes postal collections from CUSMA preference through commercial channels. Its postal warning says duties are collected regardless of CUSMA compliance. Canada Post separately requires its assessment and Declaration ID workflow. Do not assume an uploaded certificate switches a postal shipment into a commercial entry.

For a courier alternative, ask how the service submits preference, who acts as importer and who receives the customs bill. Request the complete charge structure, including clearance and advancement costs. A lower headline transport price can lose its advantage if the entry process cannot support the intended treatment. Conversely, the ability to claim preference does not guarantee that all additional measures disappear.

What should your checkout actually tell the American buyer? #

State whether the displayed total includes the import charges your service will collect, or whether charges remain payable through the delivery process. Make that statement match the service you book. If your shop collects an estimated duty amount, identify how it reaches the party handling clearance. A checkout line labeled “duties” is not evidence that money has been remitted for the parcel.

Maintain an order-level record of the terms shown at purchase. Link it to the selected carrier service and its assessment. This helps resolve a buyer’s report of a second payment request: you can check whether the request concerns government duty, an operator fee or a service booked with a different payer arrangement. Do not promise a refund for an assessment before checking that distinction.

A free-shipping offer needs the same review. Free shipping describes what you charge the customer for transport; it does not establish duty relief. If your product margin must cover shipping and import charges, assess both before extending the promotion to US destinations. For classification work, the HS versus US HTS explanation helps separate product codes from carrier settings.

Can a US sender remove the border from each customer order? #

After an inventory batch has been lawfully imported and released in the US, orders to US customers can ship domestically. With AirPost local fulfillment, a sender holds your agreed stock, packs orders and hands them to the selected carrier. The shop remains responsible for the incoming goods and their customs information; a sender’s address is a receiving location, not automatic acceptance of importer obligations.

Here is a cost floor, not a complete fulfillment quote. On AirPost’s US domestic page, a small USPS Ground Advantage parcel displayed an indicative US$7.78 starting price on October 14, 2026. Two such displayed label amounts total US$15.56. The platform fee is already included; add the sender compensation you agree, materials and the incoming batch costs. Local postage cannot cancel duty owed when stock enters the US.

The page presents converted starting amounts and says settlement is in euros. Keep the actual currency and quote when budgeting; do not silently equate a displayed US-dollar estimate with a guaranteed US-dollar invoice. The CA-to-US URL returned a Canadian domestic selection on the same date, so it supplied no usable cross-border comparator. Obtain a real southbound service quote before calculating savings.

Which products should you review before changing your whole operation? #

Start with the products you actually sell to American buyers and group them by their evidence and entry requirements. Separate unchanged imported goods from products you manufacture. Flag anything with uncertain classification, restricted content or an unsupported origin statement. Those are questions to resolve before moving stock, regardless of whether you intend to ship each order from Canada or replenish a US sender.

For each group, compare a documented direct-shipping quote with the cost of importing a batch and fulfilling domestically. Use your own order history to allocate batch costs and model unsold inventory. There is no universal volume at which a US location wins. A domestic label can improve the outbound cost while inventory, import administration or returns make the overall choice less attractive.
