For years, a lot of cross-border ecommerce quietly depended on a customs rule most shoppers had never heard of. Low-value shipments could enter many countries duty-free under a de minimis threshold, so a brand could ship a small parcel internationally without calculating duties, collecting them at checkout, or filing a formal entry. That assumption was baked into pricing, checkout, and fulfillment logic across the industry.
In 2026 that assumption came apart. The United States indefinitely suspended the de minimis exemption for imports arriving through all modes, following an earlier executive action suspending duty-free de minimis treatment for all countries. The European Union moved to remove its 150-euro customs duty exemption threshold as of 2026. The practical result is the same on both sides of the Atlantic: duties and formal handling now apply to a far wider range of international orders, including the small, low-value parcels that used to pass through untouched.
That is a policy change on paper. In an operation, it is a data and timing problem. Every affected international order now needs an accurate duty and landed-cost calculation, applied early enough to be useful, and a fulfillment path that accounts for customs. Handling that at the carrier, after the order is placed, is too late. It has to happen in the order flow.
What de minimis was quietly doing for your operation
The old thresholds did more than save shoppers money. They let brands avoid a whole class of operational work. Without duties on low-value parcels, there was no need to classify products for customs at checkout, no need to calculate and collect duties before shipping, and less need for formal customs entries on small orders. Cross-border could be treated, operationally, almost like domestic shipping with a longer transit time.
Take the exemptions away and that work comes back for every order that now falls in scope. Products need correct classification. Duties and taxes need to be calculated against the destination country’s rules. Someone has to decide whether the shopper pays those costs at checkout or receives a bill on delivery. And the fulfillment path has to route the order in a way that clears customs without stranding the parcel or surprising the customer. The orders did not get more valuable. They got more complex.
Why landed cost is an order operations decision
The instinct is to treat this as a checkout problem: add a duty estimate to the cart and move on. Accurate landed cost at checkout matters, and shoppers strongly prefer to see the full cost up front. Baymard Institute research consistently finds that the most common reason shoppers abandon at checkout is extra costs like shipping, taxes, and fees being too high or unexpected. A duty that appears as a surprise bill on the doorstep is the worst version of that problem.
But a number in the cart is only correct if it reflects where the order will actually ship from, which product is actually available, and what the destination rules actually are at that moment. Those are order operations questions. Landed cost depends on the origin warehouse, because duty and shipping differ by where the parcel starts. It depends on live inventory, because promising a duty and delivery date for a unit that is out of stock at the assumed location is a promise you cannot keep. And it depends on routing, because for many brands the right answer to higher cross-border duties is to fulfill from in-region stock where possible, which changes the calculation entirely.
So the same decision that sets the customer’s landed cost also sets the fulfillment path. Splitting those two apart, a checkout tool guessing at duties and a separate system deciding where to ship from, is how the number in the cart stops matching the parcel that arrives.
What real-time order operations do with a cross-border order
An order operations layer sits between your storefront and channels and your fulfillment network, and it makes the cross-border decisions in one place, in real time, as the order comes in.
It reads live inventory across every location, so the origin decision is based on what is actually available. It routes the order to the fulfillment node that best serves the destination, which for cross-border often means favoring in-region stock to reduce duty exposure and transit time. It calculates landed cost against the chosen origin and destination, so the duty and delivery promise reflect the real path rather than an assumption. And it does this fast enough to surface an accurate figure while the shopper is still in the cart, then carry that same decision through to fulfillment so the parcel matches what was promised.
That last point is where operations and experience meet. When landed cost is calculated from the same real-time inventory and routing logic that will fulfill the order, the customer sees an accurate total, the parcel clears customs on the expected terms, and the delivery date holds. When they are calculated separately, the gaps between them become customer-service tickets, abandoned deliveries, and refused parcels.
Building for a moving target
The specific thresholds and rules will keep changing. Suspensions can be adjusted, countries set their own thresholds, and trade policy is unusually active right now. That volatility is itself an argument for handling duties and landed cost in a layer you control rather than hard-coding assumptions into a checkout flow or a set of per-country rules that a developer has to revisit every time policy shifts.
An operation designed around real-time data adapts to a rule change as a configuration update: adjust the calculation inputs, and the routing and checkout logic that depend on them follow. An operation with de minimis assumptions baked into fixed rules has to be reworked each time, and in the meantime it is quoting customers numbers that are wrong.
Cross-border keeps getting more complex, and duty-free treatment for low-value parcels keeps narrowing. The brands that keep cross-border profitable are the ones that treat every international order as a routing and landed-cost decision made in real time, from live data, in one place, rather than a domestic order with extra paperwork bolted on at the end.
